  A speaker 5 is accommodated in the speaker accommodating portion 3a. The speaker 5 is electrically connected to the control device 12b described above. The speaker 5 is mounted so that it can receive the electric signal from the control device 12b and radiate the sound radiated from the diaphragm 38 downward. That is, as shown in FIGS. 2 and 3, the speaker 5 has a posture in which the diaphragm 38 faces downward, and the speaker main body 40 including a coil and a magnet (not shown) constituting the speaker 5 faces upward. It is inserted and accommodated from above into the accommodating portion 3a.

  The leg ceiling portion 3b is a flat plate-like portion in plan view, and has an outer diameter that is slightly larger than the outer diameter of the speaker housing portion 3a. The leg ceiling portion 3b has a through hole 3e at a substantially central portion thereof. The opening diameter of the through hole 3e is slightly smaller than the opening diameter of the speaker housing portion 3a. Therefore, the speaker 5 accommodated in the speaker accommodating portion 3a is in a state where the outer peripheral portion of the diaphragm 38 is supported by the leg ceiling portion 3b.

  The speaker housing portion 3a and the leg ceiling portion 3b are provided with a ventilation vertical through hole 51 and a ventilation horizontal through hole 52. The ventilation vertical through hole 51 is a through hole penetrating in the vertical direction. The ventilation vertical through-hole 51 has one end opened to the leg ceiling 3b and the other end opened to the inclined surface 3h of the notch 3g.

  As shown in FIG. 6D, the ventilating vertical through hole 51 has an enlarged diameter portion 51a. The enlarged diameter portion 51a is provided in a portion from the vicinity of the inclined surface 3h to the opening of the inclined surface 3h in the ventilation vertical through hole 51. When the flow direction of air or the like flowing through the ventilation vertical through hole 51 from the outside to the inside of the main body portion 2 is assumed, the enlarged diameter portion 51a passes through the ventilation vertical direction from the upstream side to the downstream side in the flow direction of the air or the like. This is a portion where the inner diameter of the through-hole 51, that is, the flow path cross-sectional area gradually increases. The channel cross-sectional area of the enlarged diameter portion 51a is larger than the channel cross-sectional area of the ventilating vertical through hole 51 on the upstream side in the flow direction of the air or the like. That is, the flow passage cross-sectional area of the enlarged diameter portion 51 a is larger than the opening area of the vent vertical through hole 51 on the leg ceiling portion 3 b side. Accordingly, the ventilation vertical through hole 51 has an opening area on the inclined surface 3h side larger than an opening area on the leg ceiling 3b side.

  Further, the ventilation side hole 52 is in the vicinity of the boundary portion between the speaker housing portion 3a and the leg ceiling portion 3b, specifically, as shown in FIG. A part of the opening region is provided so as to reach a portion deviated downward.

  A ventilation film 57 (film body) is attached to the inclined surface 3h of the notch 3g provided on the inner peripheral surface of the speaker housing 3a so as to close the opening of the ventilation vertical through hole 51. The gas permeable membrane 57 has a characteristic that allows passage of air but does not allow passage of water. Therefore, even if hot water enters from the opening on the lower surface side of the leg ceiling portion 3b, the ventilation vertical through hole 51 is prevented from moving by the ventilation film 57, and the ventilation through-hole 51 is located above the opening on the speaker housing portion 3a side. I can't get out.

  In the speaker housing portion 3 a, the inclined surface 3 h of the notch 3 g is inclined with respect to the extending direction of the ventilation vertical through hole 51. On the other hand, the ventilating vertical through-hole 51 extends linearly along the axial direction of the cylindrical speaker housing portion 3a. Therefore, the ventilation vertical through hole 51 has an opening area on the inclined surface 3h side of the speaker housing portion 3a larger than an opening area on the lower surface side of the leg ceiling portion 3b.

  Further, the inclined surface 3h is located at the end of the enlarged diameter portion 51a, that is, at the downstream side in the flow direction of air or the like flowing in the flow direction of air or the like flowing through the ventilation through hole 51 from the outside to the inside of the main body portion 2. Therefore, the ventilating vertical through hole 51 has an inner diameter (channel cross-sectional area) on the inclined surface 3h side, an inner diameter (channel cross-sectional area) on the upstream side in the flow direction of air or the like, and the leg ceiling portion 3b. It is larger than the opening diameter (opening area). Therefore, the opening area of the ventilation vertical through hole 51 on the inclined surface 3h side is further enlarged by the amount of the enlarged diameter portion 51 compared to the case where the inclined surface 3h is simply provided and the opening area is enlarged. Therefore, the ventilation membrane 57 is attached to the opening portion on the lower surface side of the leg ceiling portion 3 b or the ventilation vertical through hole 51 as compared with the case where the ventilation membrane 57 is attached so as to cross substantially perpendicular to the ventilation vertical through hole 51. The area that crosses (the cross-sectional area) is large.

  On the other hand, the ventilation side holes 52 are opened in the outer peripheral surface of the speaker housing 3a. Specifically, among the openings of the ventilation lateral holes 52 formed on the outer peripheral surface of the speaker housing 3a, the upper part in FIG. 6C is formed in the protrusion 43a, and the lower part is It is located on the radially inner side of the speaker housing 3a than the protrusion 43a. In other words, the opening portion of the vent hole 52 has a step difference between the upper portion and the lower portion. When viewed from the outside of the speaker housing portion 3a, the lower portion is compared to the upper portion. It is the state located in the back side (diameter direction inner side of the speaker accommodating part 3a).

  The leg bottom portion 3c has a shape having a conical portion 3f having a substantially mountain shape in the substantially central portion of a plate body that is substantially circular in plan view. The conical portion 3f is inclined at the same inclination over substantially the entire circumference so that the top portion is located on the central axis passing through the center of the through hole 3e. The standing portion 3d is a portion erected between the leg ceiling portion 3b and the leg bottom portion 3c so as to be connected to each other, and is provided at two positions in the circumferential direction of the leg portion 3 that are shifted from each other by 180 degrees. Yes. In the outer periphery of the leg bottom 3c excluding the position where the standing part 3d is provided, the leg 3 is opened with the space between the leg top 3b and the leg bottom 3c facing outward in the circumferential direction of the leg 3. It is in the state.

  As shown in FIG. 2 and FIG. 6B, the leg portion 3 has a flange portion 24b provided at the lower end portion of the built-in case 8 in the state where the speaker 5 is accommodated in the speaker accommodation portion 3a. While engaging with 3a from above, the engaging portion 24c provided on the lower side of the flange portion 24b is engaged with the notch portion 3g provided in the speaker accommodating portion 3a, and the flange portion 24b, the speaker accommodating portion 3a, It is integrated by screwing. Specifically, as described above, the lower surface side of the engaging portion 24c and the inclined surface 3h constituting the cutout portion 3g of the speaker housing portion 3a are both inclined, and the inclinations of both are the same. ing. Therefore, when the built-in case 8 and the leg portion 3 are integrated, the lower surface side of the engaging portion 24c and the inclined surface 3h face each other substantially in parallel as shown in FIG. The air-permeable membrane 57 is sandwiched between them. In addition, as a result, the ventilating vertical through holes 50 and 51 are continuous in the vertical direction through the vent film 57.

  By integrating the built-in case 8 and the leg 3 as described above, a ventilation path 55 is formed by the ventilation vertical through holes 50 and 51 and the ventilation lateral hole 52. That is, in a state where the main body portion 2 and the leg portion 3 are integrated, the air passage 55 is formed on the region A side formed with the boundary surface X that vertically cuts the main body portion 2, and the main body on the region B side. A case body 20 that forms the main part of the part 2 is formed.

  Here, as described above, the ventilating vertical through-hole 51 provided on the leg 3 side has a configuration in which the ventilating film 57 is attached to the opening on the inner peripheral surface 3g side of the speaker housing 3a. . Therefore, when the built-in case 8 and the leg portion 3 are integrated, the ventilation film is formed so as to intersect the extending direction of the ventilation path 55 in the middle of the ventilation path 55 extending linearly in the vertical direction in a normal installation state. 57 is provided.

  As shown in FIG. 6B and the like, the ventilation film 57 is provided so as to merge with a series of passages (hereinafter also referred to as main ventilation passages 55a) constituted by the ventilation vertical through holes 50 and 51. It exists in a position closer to the inside of the main body cylinder 2 than the horizontal hole 52 (hereinafter also referred to as a secondary ventilation path 55b). That is, when the outer side of the main body 2 is defined as the upstream side in the flow direction of air or water in the ventilation path 55 and the inner side of the main body 2 is defined as the downstream side, the secondary ventilation path 55b constituted by the ventilation lateral holes 52 is provided for ventilation. It communicates with the main ventilation path 55a on the upstream side with respect to the ventilation film 57 provided in the middle of the main ventilation path 55a constituted by the vertical through holes 50 and 51.

  Further, when the bottom part 22 and the leg part 3 of the main body part 2 are integrated, the diaphragm 35 of the speaker 5 attached to the main body part 2 side is connected to the leg bottom part 3c through the through hole 3e provided in the leg top part 3b. It will be in the state which opposes the cone part 3f provided in. Therefore, the sound radiated from the speaker 5 hits and reflects off the conical part 3f provided on the leg bottom part 3c, and spreads outward from the open part provided on the side of the leg part 3.

  The audio apparatus 1 of the present embodiment integrates the main body 2 and the leg 3 as described above, and covers the outer cover 7 from above the main body 2 to rotate the outer cover 7 in the circumferential direction. It is formed by screwing a screw (not shown) formed inside the exterior cover 7 and a connecting means 41 provided on the leg 3. In the audio device 1 with the outer cover 7 attached, the inner peripheral surface of the outer cover 7 is in surface contact with the protruding portion 43a provided on the outer periphery of the speaker housing portion 3a constituting the leg 3, and the groove 43b It is sealed by the provided O-ring 45. Thereby, a watertight space (watertight portion 47) is formed inside the main body 2.

  As shown in FIG. 6B, in the audio device 1, a slight gap 60 is formed between the lower end portion of the outer cover 7 and the leg top portion 3 b of the leg portion 3 in a state where the outer cover 7 is attached. The Further, as described above, the vent holes 52 provided in the outer peripheral surface of the leg portion 3 have different opening portions, and are lower than the protrusion 43a in a state where the leg portion 3 is observed from the outside. The part is located behind the upper part, that is, on the radially inner side of the leg part 3. Therefore, in a state in which the exterior cover 7 is attached, a part of the opening of the ventilation lateral hole 52, that is, the lower part of the opening is separated from the exterior cover 7. Further, the ventilation side hole 52 is opened slightly above the portion where the gap 60 is formed. Therefore, the audio apparatus 1 has a ventilation region 65 through which air from the gap 60 to the ventilation side hole 52 can pass, as indicated by arrows in FIGS. 6B and 6D. Further, as shown by arrows in FIGS. 6B and 6D, the ventilation region 65 once rises up the air flowing inward from the gap 60 and then guides it to the ventilation side hole 52. It is possible shape.

In addition, the audio device 1 is mounted so as to cover the exterior cover 7 that is the second component member with respect to the built-in case 8 and the leg portion 3 that is the first component member, and relatively rotates the exterior cover 7 and the leg portion 3. As a result, both are engaged, and a watertight portion 47 is formed inside. When the outer cover 7 and the leg 3 are thus relatively rotated until they are engaged with each other, the buttons 17 provided on the top surface 7a of the outer cover 7 are provided on the top surface 21a of the built-in case 8. Arrives at a position corresponding to each opening 27.

  That is, in the audio device 1 of the present embodiment, the buttons 17 provided on the top surface 7a and the openings 27 provided on the top surface 21a of the built-in case 8 are arranged so that the exterior cover 7 and the leg 3 are arranged. It is adjusted so that it will arrive at the position corresponding to each other only after it will be in the engaged state. Accordingly, the audio device 1 engages the exterior cover 7 and the leg portion 3 and presses the button 17 provided on the top surface of the exterior cover 7 unless the watertight portion 47 formed by the both is firmly watertight. Even so, the switches 30 provided on the control device 12a inside the opening 27 of the built-in case 8 cannot be operated.

  The audio device 1 has a light-transmitting property with the display device 29 provided on the arc portion 23 of the case body 20 constituting the built-in case 8 from the outer peripheral surface 7b side of the outer cover 7 in a state where the outer cover 7 is attached. It can be visually recognized from the outer peripheral surface 7 b of the exterior cover 7.

  Further, as shown in FIG. 2B, the audio device 1 projects the extended portion 13 of the exterior cover 7 toward the installation surface in a state where the leg portion 3 is installed on the installation surface with the legs 3 facing downward. A projection area β formed by projecting the speaker 5 toward the installation surface is included in the formed projection area α. Therefore, in the audio device 1, the exterior cover 7 functions as an umbrella with respect to the speaker 5, and even if hot water is applied from above the audio device 1, this prevents the speaker from getting wet directly. Can be prevented.

  Next, the normal usage pattern and the normal usage pattern of the audio apparatus 1 will be described. The audio device 1 can be suitably used in an environment where hot water is used, such as in a bathroom or kitchen, or outdoors, and can be carried and installed in any place according to the user's wishes. . The audio device 1 is used by setting a battery in a battery box 6 inside the built-in case 8. That is, the audio apparatus 1 is configured to operate using a battery set in the battery box 6 as a power source. The audio device 1 is used in a state where an external memory 33 such as a USB memory in which music data is recorded is connected to a connection terminal 31 provided in the built-in case 8.

  The audio apparatus 1 is installed on an installation surface composed of a shelf or a stand provided in a bathroom, kitchen, or the like, with the legs 3 facing downward and the main body 2 standing up as shown in FIG. As a result, the audio device 1 is in a state in which the portion forming the bottom surface of the main body 2, that is, the leg ceiling 3 b of the leg 3 is separated upward from the installation surface. Further, the ventilation vertical through hole 51 of the ventilation path 55 provided in the leg ceiling 3b is in a state of opening downward.

  In the audio apparatus 1, the case main body 20 exists on the region B side with the boundary surface X as a boundary. For this reason, when the audio device 1 is installed so that the user can visually recognize the display device 20 provided in the case body 20, the region A is positioned on the side opposite to the user side. That is, the display device 20 is located on the front side with respect to the user, and the region A is located on the back side. Therefore, when the audio device 1 is installed so that the user can visually recognize the display device 20, the air passage 55 provided in the region A is positioned on the back side as viewed from the user.

  The audio device 1 can operate the control device 12a by pressing the button 17 provided on the top surface 7a of the exterior cover 7 in the state of being installed as described above. Then, by performing a predetermined operation using the button 17, the audio data recorded in the external memory 33 can be reproduced via the speaker 5 provided on the bottom side of the main body 2. The sound radiated from the speaker 5 is reflected by the leg bottom 3c of the leg 3 and the mountain-shaped cone 3f (reflecting part) provided on the leg 3 and is emitted toward the outside of the audio device 1.

  In the state of being installed as described above, the audio device 1 has substantially the same pressure inside and outside the main body 2 regardless of the temperature of the installation atmosphere. That is, as described above, in the audio device 1, the ventilation vertical through hole 51 constituting the ventilation path 55 is opened in the leg ceiling 3 b of the leg 3 that closes the bottom side of the main body 2. Through this, the inside and outside of the main body 2 communicate with each other in the vertical direction on the basis of the installation state. Further, the ventilation side holes 52 constituting the ventilation path 55 are opened in the outer peripheral surface of the leg ceiling part 3b constituting the leg part 3, and the vertical direction in which the ventilation vertical through holes 50 and 51 are formed to communicate with each other. It communicates with the passage that extends to. Further, as shown in FIG. 6B and the like, the ventilation vent 52 communicates with the outside of the audio device 1 through a gap 60 and a ventilation area 65 formed between the leg ceiling 3b and the outer cover 7. ing. Therefore, the audio apparatus 1 is in a state in which the main body 2 can be ventilated through the ventilation path 55. Therefore, even if the audio apparatus 1 is installed in an atmosphere with a large change in room temperature such as a bathroom, the inside and outside of the main body 2 are maintained at substantially the same pressure. Therefore, even if the audio apparatus 1 is used in an atmosphere such as a bathroom where the change in room temperature is large, problems such as the malfunction of the speaker 5 or the malfunction of the speaker 5 are unlikely to occur.

  As described above, in the ventilation path 55a, the ventilation film 57 that allows the passage of air and does not allow the passage of moisture is provided in the middle of the main ventilation path 55a constituted by the vertical through holes 50 and 51 for ventilation. Yes. Further, the main ventilation path 55a constituting the ventilation path 55 is opened downward in a normal installation state. Therefore, even if the audio apparatus 1 is used in an environment where hot water is applied as in a bathroom, the hot water does not easily enter the main body 2 through the main ventilation path 55a.

  In the audio device 1, the opening of the secondary ventilation path 55 b is located inside the exterior cover 7 in the assembled state of the audio device 1. Furthermore, the audio device 1 has a flow path from the gap 60 formed between the exterior cover 7 and the leg top 3b of the leg 3 to the opening of the secondary ventilation path 55b through the ventilation area 65. The flow of air or the like flowing from the outside through the flow path rises upward in the middle. Therefore, even if hot water flows in through the gap 60, the moisture may fall due to its own weight while passing through the ventilation region 65, and the moisture will enter the ventilation side hole 52 constituting the secondary ventilation path 55b. The possibility of intrusion can be minimized.

  Moreover, when the audio apparatus 1 is installed in a normal posture, the ventilating horizontal hole 52 is opened at a position higher than a portion where the gap 60 is provided. For this reason, even if hot water enters the gap 60, it is unlikely that it directly flows into the vent hole 52. Furthermore, the ventilation side hole 52 is connected to the main ventilation path 55 a on the upstream side in the flow direction of air or the like introduced from the outside through the main ventilation path 55 with respect to the ventilation film 57 provided in the middle of the main ventilation path 55. Have joined. For this reason, even if hot water enters the ventilation side hole 52 constituting the secondary ventilation path 55b, this does not enter the main body 2.

  As described above, the air passage 55 has the main air passage 55a extending in the vertical direction in the normal installation state and the sub air passage 55b extending in a direction intersecting with the main air passage 55a, and both join together. Therefore, in the audio apparatus 1, even if a water film is formed in the main air passage 55a, the water film is eliminated by the air introduced from the outside through the sub air passage 55b. Air introduced through 55b can be introduced into the inside of the main body 2. Therefore, the audio apparatus 1 can smoothly enter and exit the main body 2. Therefore, the audio apparatus 1 can maintain the inside and outside of the main body 2 at substantially the same pressure even when installed in a bathroom or the like where the temperature changes greatly, and can prevent malfunction or failure of the speaker 5 or the like.

  As described above, in the audio device 1, the main ventilation path 55a and the secondary ventilation path 55b communicate with each other, and both the primary ventilation path 55a and the secondary ventilation path 55b can take in air from the outside. Therefore, in the audio apparatus 1, the air flowing through the main air passage 55a and the air flowing through the sub air passage 55b collide with each other (55a, 55b) in the air passage 55, resulting in a turbulent state. Further, the junction of the main ventilation path 55 a and the secondary ventilation path 55 b is upstream of the ventilation film 57 in the flow direction of air or the like and is near the ventilation film 57. Therefore, in the audio device 1, the ventilation film 57 is exposed to air in a turbulent state. Therefore, even if the audio device 1 is formed with a water film so as to cover the surface of the ventilation film 57 or the water film extends across the flow path in the middle of the ventilation path 55, the water film Is likely to be resolved by exposure to air in a turbulent state as described above. Therefore, in the audio device 1, there is a possibility that air cannot pass through the air passage 55 due to a water film being stretched or the like, or a pressure difference between the inside and the outside of the main body 2 is generated due to this. Low.

  As described above, the audio device 1 is used by being installed in a posture in which the legs 3 are directed downward on an installation surface such as a bathroom, a kitchen, or the outdoors. However, the audio device 1 is not a so-called stationary device that is fixedly used with respect to the installation surface, such as a remote control device installed in a bathroom, but is installed and used by a user at a desired position. This is a so-called portable device. Therefore, when the user's body or object hits or the installation surface shakes, the audio device 1 falls on the installation surface or falls from the installation surface, and hot water such as a bathtub or a sink is collected. There is a possibility of falling to the place. In this case, when the audio device 1 is submerged, or when hot water enters the air passage 55 provided in the audio device 1 to form a water film so that air cannot reach the main body 2, the speaker 5. Therefore, there is a possibility that troubles such as no longer radiating sound or failure of the speaker 5 may occur.

  Therefore, assuming such a situation, as shown in FIGS. 7A and 7B, the audio device 1 of the present embodiment is provided in the leg ceiling portion 3 b even when it is dropped with respect to the water surface M. The opening of the vertical ventilation hole 51 for ventilation constituting the main ventilation path 55a and the opening of the horizontal ventilation hole constituting the secondary ventilation path 55b are floated on the water surface M in a posture positioned above the water surface M. Yes. More specifically, as described above, the audio device 1 of the present embodiment has the battery box 6 in the region B on one side partitioned by the boundary surface X, and is used in a state where a battery is set in the battery box 6. Is done. Further, the main part of the control device 12a constituting the audio device 1, the control device 12b, and the display device 29 are also present on the region B side.

  On the other hand, the audio device 1 is a space inside the exterior cover 7, and a portion corresponding to the region A located on the opposite side to the region B is substantially hollow. In the audio device 1 of the present embodiment, the speaker 5 is provided on the bottom side of the main body 2. Therefore, the audio device 1 has a weight balance (center of gravity) on the region B side and biased toward the bottom side of the main body 2.

  The audio apparatus 1 has a space on the region B side as well as the cavity on the region A side as described above. Therefore, as shown in FIG. 7, the audio device 1 floats on the water surface M without being submerged even if it falls on the water surface M such as a bathtub filled with hot water. In addition, since the center of gravity is unevenly distributed on the region B side, the audio device 1 floats on the water surface M in a posture in which the region A side faces upward with respect to the region B side. Therefore, the audio device 1 falls toward the water surface M at the opening of the ventilation vertical through hole 51 of the ventilation path 55 provided on the leg top surface 3b and the opening of the ventilation horizontal hole 52 provided on the leg 3. However, it is always located above the water surface M. Therefore, in the audio device 1 in a state where it floats toward the water surface M, there is a low possibility that hot water enters from the opening of the ventilation vertical through hole 51 and the ventilation horizontal hole 52.

  In addition, since the center of gravity of the audio device 1 is biased toward the bottom side of the main body 2, the audio device 1 is inclined so that the bottom side is slightly lower than the top surface side of the main body 2. Therefore, as shown in FIG. 7B, the main ventilation path 55 a is inclined downward as it goes from the inside to the outside of the main body 2 when the audio device 1 is floating on the water surface M.

  Further, the ventilation side hole 52 is in a state of being slightly inclined with respect to the vertical direction and communicating in the vertical direction. Therefore, even if the audio device 1 may have hot water infiltrated into the ventilating vertical through hole 51 or the ventilating horizontal hole 52 due to the influence of the rippling water surface M due to an impact at the time of dropping, etc. The hot water flows toward the outside of the main body 2 along the inclination of the main ventilation path 55a and the secondary ventilation path 55b, and is discharged. Therefore, when the audio device 1 falls toward the water surface M, even if hot water enters from the opening of the ventilation vertical through hole 51 or the ventilation horizontal hole 52 for some reason, it immediately flows outward. Problems such as hot water remaining in the air passage 55 or a water film formed in the air passage 55 so that the air cannot reach the main body 2 are unlikely to occur.

  In addition, even when the audio device 1 is dropped toward the water surface M, when the audio device 1 is picked up and used in a normal usage mode, the air smoothly flows inside and outside the main body 2 through the air passage 55. Since it can go back and forth, the pressure inside and outside the main body 2 is maintained at substantially the same pressure, and the malfunction of the speaker 5 or the malfunction of the speaker 5 is less likely to occur.

  In the audio device 1 of the above embodiment, the main ventilation path 55a (the ventilation vertical through holes 50 and 51) constituting the ventilation path 55 in a state of being floated on the water surface M is obliquely downward from the inside to the outside of the main body. However, the present invention is not limited to this, and the main ventilation path 55a may be horizontal with respect to the water surface M, for example.

  When the audio device 1 floats on the water surface M, the direction of the main air passage 55a and the sub air passage 55b is as described above. Even if the hot water falls into the air passage 55, even if a small amount of hot water enters the air passage 55, the hot water may accumulate in the air passage 55 or enter the air passage 55. It is possible to prevent the formation of a water film that inhibits the passage of gas (air).

  In the audio device 1 shown in the above embodiment, the battery box 6 containing the battery, the control device 12b, the display device 29, and the like are unevenly distributed on the region B side, and at the top portion 21 of the built-in case 8 constituting the main body portion 2. The loudspeaker 5 that is heavier than the control device 12a accommodated is provided on the bottom side of the main body 2, and the members are arranged so that the center of gravity is on the region B side and is located on the bottom side of the main body 2. Was. However, the present invention is not limited to this. For example, by appropriately adjusting the position of the speaker 5 and the battery box 6 and the like, the weight balance between the top surface side and the bottom side of the main body 2 is substantially uniform. It is good also as the structure which carried out.

  In the audio device 1 shown in the above embodiment, in a normal usage pattern, the central axis of the main body 2 made of a cylindrical body is oriented vertically and the legs 3 are directed downward, and the legs 3 are installed. Used on the surface. In this state, the opening of the main air passage 55 a constituting the air passage 55 is open to the leg ceiling portion 3 b of the leg portion 3 that forms the bottom of the main body portion 2. For this reason, the audio device 1 may have a possibility that hot water may enter the air passage 55 or a water film may be formed in the air passage 55 even if a shower is taken from above in a state where the audio device 1 is installed in the bathroom. Low.

  In addition, the audio device 1 forms the bottom of the main body 2 and is located on the peripheral edge of the speaker 5 accommodated in the speaker accommodating portion 3 a of the leg 3, and functions as a support for the speaker 5. A main air passage 55a constituting the air passage 55 is opened. That is, in this embodiment, the vertical leg through hole 51 that forms the main ventilation path 55 a is formed in the annular leg ceiling 3 b provided to support the speaker 5, and is provided in the leg 3. The space is used as much as possible. Therefore, according to the above-described configuration, the speaker 5 having the large diaphragm 38 can be adopted while the audio device 1 is made compact.

  The audio device 1 described above has a configuration in which the main body portion 2 has a cylindrical shape, and the diaphragm 38 of the speaker 5 provided on the bottom side can emit sound toward the lower side of the main body portion 2. Then, the audio device 1 has the leg ceiling 3a that forms the bottom of the main body 2 and the watertight portion 47 formed in the main body 2 in a state where the leg 3 is installed on a predetermined installation surface with the legs 3 facing downward. Exists at a position away from the installation surface. Therefore, in the audio device 1, even if the main body 2 is wet with hot water in a normal usage pattern, the possibility that the speaker 5 gets wet with hot water or breaks down is low.

  In the above-described embodiment, an example in which the speaker 5 is classified as a cone type according to the shape of the diaphragm 38 is exemplified, but the present invention is not limited to this, and a dome-shaped diaphragm is used. It may be classified into a dome type speaker, a flat type, a bending wave type, or the like. Further, the speaker 5 can be appropriately selected from those known in the art such as those classified into dynamic types by classification based on conversion methods, magnetic types, capacitor types (electrostatic types), and piezoelectric types. The speaker 5 can be appropriately selected for classification based on the vibration radiation method and classification based on the reproduction band.

  The audio apparatus 1 shown in the above embodiment is provided with a ventilation film 57 in the middle of the main ventilation path 55a constituting the ventilation path 55, and is attached so as to be inclined with respect to the extending direction of the main ventilation path 55a. The cross-sectional area of the ventilation film 57 was large. However, the present invention is not limited to this, and a ventilation film 57 is extended to the opening portion of the main ventilation path 55a formed in the middle of the main ventilation path 55a or at the end on the main body 2 side. It is good also as a structure attached so that it might orthogonally cross with respect to the direction.

  Also, the audio device 1 has a configuration in which the enlarged diameter portion 51a is provided in the vicinity of the opening on the inclined surface 3h side of the vertical ventilation hole 51 for ventilation that forms the middle of the main ventilation passage 55a, and the ventilation film 57 is attached thereto. However, the present invention is not limited to this. Specifically, it is configured not to have the enlarged diameter portion 51a, or in the vicinity of the opening on the main body 2 side of the main ventilation path 55a, that is, in the middle of the ventilation vertical through hole 50 or in the vicinity of the opening of the ventilation vertical through hole 50. It is good also as a structure which provided the enlarged diameter part 51a and attached the ventilation film 57 to the said enlarged diameter part 51a.

  Moreover, in the said embodiment, the structure which attached the ventilation film 57 to the terminal part of the enlarged diameter part 51a, ie, the opening part by the side of the inclined surface 3h located in the flow direction downstream of the air etc. which flow through the main ventilation path 55a was illustrated. However, the present invention is not limited to this, and the gas permeable membrane 57 may be attached to a position corresponding to a midway in the flow direction of air or the like in the enlarged diameter portion 51a. Also in the case of such a configuration, the gas permeable membrane 57 is mainly used as compared with the case where the gas permeable membrane 57 is not provided, or the gas permeable membrane 57 is attached to a portion upstream of the diameter enlarged portion 51a in the flow direction of air or the like. The area of the region exposed to the air flowing through the ventilation path 55a can be increased.

  Further, if the enlarged diameter portion 51a is provided as described above, or the inclined surface 3h is provided to ensure a large area where the ventilation film 57 is exposed to the air flowing through the main ventilation path 55a, the main ventilation path 55a is provided. On the other hand, an opening functioning as an entrance for air or the like from the outside, that is, an opening provided in the leg ceiling portion 3b can be suppressed to a necessary minimum. For this reason, with the above-described configuration, entry of hot water from the outside into the air passage 55 is minimized, and a water film is formed so as to block the air passage 55. It is possible to suppress the occurrence of problems such as malfunctions and failures. In addition, by suppressing the opening diameter of the main air passage 55a to a minimum, it is possible to prevent the occurrence of problems such as foreign matter entering the air passage 55 or damage to the air-permeable membrane 57 due to foreign matter.

  In the said embodiment, although the enlarged diameter part 51a was provided in the middle of the main ventilation path 55a, and the structure which attached the ventilation film 57 to this was illustrated, this invention is not limited to this, The enlarged diameter part 51a is provided. It is good also as a structure which does not provide. Moreover, in the said embodiment, while providing the enlarged diameter part 51a, the inclined surface 3h is provided in the terminal part of the enlarged diameter part 51a, ie, the position of the edge part of the flow direction downstream side of the air etc. which flow through the main ventilation path 55a. Although the configuration in which the area of the region where the air-permeable membrane 57 is exposed to the air flowing through the main air passage 55a due to the synergistic effect is increased, only one of the configurations may be employed. Even in the case of such a configuration, the main body 2 can be sufficiently ventilated, and problems and failures of the speaker 5 can be suppressed.

  In the above embodiment, the ventilation film 57 is provided in the middle of the main ventilation path 55a. However, the present invention is not limited to this, and the middle of the secondary ventilation path 55b or the secondary ventilation path 55a. A structure corresponding to the gas permeable membrane 57 may be provided at a boundary portion with the air passage 55b or the like. Further, the ventilation film 57 may be provided at a plurality of locations of the ventilation path 55.

  Although the boundary surface X assumed in the audio device 1 described above passes through substantially the center of the audio device 1 and vertically cuts the main body 2, the present invention is not limited to this. That is, the boundary surface X may cross the main body 2 or may cross (pass through) the axis of the main body 2 obliquely. Also in the case of such a configuration, as described in the audio device 1 described above, the center of gravity is in one area defined by the boundary surface X, the air passage 55 is opened in the other area, and the water surface M The air passage 55 is positioned above the water surface M in a state where the air passage 55 is floated, and the air passage 55 is horizontal or inclined downward from the inside to the outside of the main body 2. it can. Even in the case of such a configuration, it is possible to prevent the speaker 5 from malfunctioning or malfunctioning due to the accumulation of hot water in the air passage 55 or the formation of a water film in the air passage 55. Can do.
