Detailed Description
Fig. 1 is a schematic diagram of an electronic device according to an embodiment of the invention. Referring to fig. 1, in the present embodiment, an electronic device 100 includes a housing 110 and a magnetic element 120. The electronic device 100 includes a processor, a circuit board, a battery, a display panel, a touch panel, an input/output port, or other suitable electronic components, which are not shown, and are disposed in the housing 110. The magnetic element 120 is disposed in the housing 110 and located in the housing 110, for example, at the side 112 of the housing 110. Thereby, the housing 110 of the electronic device 100 can be connected to another object 102 through the magnetic element 120.
In detail, in the embodiment, the electronic device 100 is, for example, a tablet PC (tablet PC), and the object 102 is, for example, an expansion seat having a keyboard module and a touch pad. The electronic device 100 of the present embodiment is further configured with a combining portion 130, which is located at the side 112 of the housing 110 and is adjacent to the magnetic element 120. Correspondingly, the object 102 is configured with another combining portion 102a corresponding to the combining portion 130 and another magnetic element 102b corresponding to the magnetic element 120. The combining portions 130 and 102a are, for example, a combination of a slot and a buckle, but the invention is not limited thereto. Thus, the housing 110 is adapted to be coupled to the coupling portion 102a of the object 102 through the coupling portion 130, and to be coupled to the object 102 through the magnetic element 102b attracted to the object 102 by the magnetic element 120. In other words, the housing 110 of the electronic device 100 may be further connected to the object 102 by mechanical force and magnetic attraction. However, the present invention is not limited to the configuration of the connection portion 130, and it can be adjusted according to the requirement.
In addition, in other embodiments not shown, the electronic device may also be a notebook computer. The casing and the electronic components arranged in the casing form an upper body, and the object can be a lower body of the electronic device. The upper body composed of the casing and the electronic component and the lower body as the object can be connected by a pivot module, so that the upper body can rotate relative to the lower body, and is also connected to the lower body through a magnetic element arranged in the casing, and further covers the lower body, so that the notebook computer as the electronic device is in a closed state. In addition, the magnetic element used in the electronic device is not limited to be used as a connecting member, and can also be used for triggering the sensing element located in the lower body to turn on the sleep state. The invention does not limit the type of the electronic device and the usage of the magnetic element.
Fig. 2 is a partial schematic view of the electronic device of fig. 1. Fig. 3 is a partial schematic view of the enclosure structure of fig. 2. Fig. 4 is a cross-sectional schematic view of the electronic device of fig. 2. Referring to fig. 1 to 4, in the present embodiment, the housing 110 of the electronic device 100 is adapted to be connected to the object 102 or removed from the object 102 by the movement of the magnetic element 120, and the magnetic element 120 generates a hitting sound when contacting the internal structure of the housing 110 due to the movement. The impact sound is more harsh, so the sound box structure 140 is configured in the housing 110 of the electronic device 100 to change the frequency of the impact sound, so that the electronic device 100 generates a specific impact sound.
Specifically, in the present embodiment, the electronic device 100 includes a housing 110, a magnetic element 120, and a sound box structure 140. The housing 110 has a receiving groove 114 located in the housing 110. The speaker structure 140 is located in the housing 110 and adjacent to the receiving groove 114. The acoustic enclosure structure 140 includes a resonant cavity 142 and an acoustic outlet 144. The resonant cavity 142 is connected to the receiving cavity 114, and the sound outlet 144 penetrates through the housing 110 and is connected to the resonant cavity 142. The magnetic element 120 is disposed in the receiving groove 114 and is adapted to move in the receiving groove 114, such that the housing 110 is adapted to be attached to the object 102 or removed from the object 102 by the side 112 (as shown in fig. 1). In the embodiment, the accommodating groove 114 and the sound box structure are adjacent to the side 112 of the casing 110, so that the casing 110 is suitable for being connected to the object 102 by the side 112, but the invention is not limited thereto. The impact sound generated when the magnetic element 120 moves in the receiving cavity 114 and contacts the receiving cavity 114 is transmitted out of the sound outlet 144 after the resonant cavity 142 changes the frequency from the receiving cavity 114.
Furthermore, in the present embodiment, the electronic device 100 further includes a magnetic induction element 150. The magnetic sensing element 150 is disposed at a side of the receiving slot 114 away from the side 112. The magnetic element 120 is, for example, a magnet, and the magnetic induction element 150 is, for example, a metal sheet, but the invention is not limited thereto. In addition, the electronic device 100 further includes two buffer elements 160a and 160b and a metal element 170. The buffer elements 160a and 160b are disposed on opposite sides of the magnetic element 120, and the metal element 170 is disposed between the magnetic element 120 and the magnetic induction element 150, so as to enhance the magnetic attraction between the magnetic element 120 and the magnetic induction element 150. In other words, the buffering element 160a and the metal element 170 are located between the magnetic element 120 and the magnetic induction element 150, and the buffering element 160b is located between the magnetic element 120 and the side 112. However, the present invention is not limited to the arrangement of the buffer elements 160a and 160b and the metal element 170, and can be adjusted according to the requirement.
In the present embodiment, the height H1 of the accommodating slot 114 in the moving axial direction D1 is greater than the width W1 of the magnetic element 120 in the moving axial direction D1. The width W1 shown in fig. 4 is actually the thickness of the magnetic element 120, the buffer elements 160a and 160b, and the metal piece 170 stacked on top of each other. However, the present invention is not limited to the magnetic sensing element 150, the buffering elements 160a and 160b and the metal element 170, and they can be adjusted according to the requirement. Therefore, in other embodiments without the buffer elements 160a and 160b and the metal element 170, the width W1 is the thickness of the magnetic element 120. Thus, the above-mentioned dimension of the receiving slot 114 allows the magnetic element 120 to move in the moving axial direction D1 toward the magnetic sensing element 150 or the side 112 of the housing 110 relative to the receiving slot 114.
Thus, in the present embodiment, the magnetic element 120 is adapted to be attracted to the magnetic sensing element 150 to contact a side of the accommodating groove 114 far from the side 112, and is adapted to be attracted by the magnetic element 102b (shown in fig. 1) of the object 102 when the casing 110 approaches the object 102, and move a distance along the moving axial direction D1 to contact and impact a side of the accommodating groove 114 near the side 112, and further make the casing 110 adhere to the object 102 to connect the side 112 to the object 102. The buffering elements 160a and 160b are adapted to correspondingly contact the magnetic sensing element 150 (as shown in fig. 2) or a side of the receiving slot 114 adjacent to the side 112 (as shown in fig. 4) when the magnetic element 120 moves in the receiving slot 114, but the impact sound is generated when the magnetic element 120 moves to contact the magnetic sensing element 150 or the side of the receiving slot 114 adjacent to the side 112.
In other words, in the embodiment, when the housing 110 is not close to the object 102, the magnetic element 120 is attracted to the magnetic induction element 150. When the housing 110 approaches the object 102, the magnetic element 120 is attracted by a magnetic element 102b (shown in fig. 1) on the object 102, and the magnetic attraction between the magnetic element 120 and the magnetic element 102b is greater than the magnetic attraction between the magnetic element 120 and the magnetic induction element 150, so that the magnetic element 120 is turned to move toward the side 112 corresponding to the object 102, and the housing 110 is thereby coupled to the object 102 with the side 112. The above design can extend the distance between the magnetic element 120 and the side 112 and the object 102, so as to prevent the magnetic element 120 from being attracted by the magnetic element 102b on the object 102 when the housing 110 is close to the object 102 but the distance is short of a predetermined condition, or prevent the magnetic element 120 from being attracted by other magnetic devices placed near the housing 110 to affect the operation of the electronic device 100.
On the other hand, in the present embodiment, the resonant cavity 142 of the sound box structure 140 is located at one side of the receiving groove 114 and is connected to the receiving groove 114, and the sound outlet 144 penetrates through the casing 110 and is connected to the resonant cavity 142. In other words, the receiving cavity 114, the resonant cavity 142 and the sound outlet 144 are communicated with each other and further communicated to the outside of the casing 110. Thus, when the housing 110 is connected to the object 102 through the magnetic element 120, the magnetic element 120 moves from the magnetic sensing element 150 toward the side 112 corresponding to the object 102, and then hits a side of the receiving groove 114 adjacent to the side 112. At this time, when the housing 110 is connected to the object 102, the impact sound generated by the magnetic element 120 moving to the side of the receiving slot 114 adjacent to the side 112 can be transmitted out of the sound outlet 144 from the receiving slot 114 through the resonant cavity 142 after changing the frequency. The impact sound coming out through the sound outlet hole 144 is different from the impact sound generated by the magnetic element 120 directly impacting the side 112 of the housing 110. Thus, the electronic device 100 can generate a specific impact sound. Similarly, when the housing 110 is removed from the object 102, the magnetic element 120 moves to the magnetic sensing element 150 again and adheres to the magnetic sensing element 150, so that the impact sound generated by the magnetic sensing element 150 can also be transmitted out of the sound outlet 144 from the accommodating groove 114 through the resonant cavity 142 after changing the frequency.
Specifically, in the present embodiment, the volume of the receiving groove 114 is greater than the volume of the resonant cavity 142, and the volume of the resonant cavity 142 is greater than the volume of the sound outlet 144. More specifically, the cross-sectional area of the receiving groove 114 (indicated by the height H1 of the receiving groove 114 in the moving axial direction D1 in fig. 4) is larger than the cross-sectional area of the resonant cavity 142 (indicated by the height H2 of the resonant cavity 142 in the moving axial direction D1 in fig. 4), and the cross-sectional area of the resonant cavity 142 is larger than the cross-sectional area of the acoustic port 144 (indicated by the width W2 of the acoustic port 144 in fig. 4).
Furthermore, in this embodiment, the sound box structure 140 further includes a channel 146. The accommodating groove 114 is communicated to the resonant cavity 142 through the passage 146, wherein a cross-sectional area of the passage 146 (indicated by a height H3 of the passage 146 in the moving axial direction D1 in fig. 4) is smaller than a cross-sectional area of the resonant cavity 142 (indicated by a height H2 of the resonant cavity 142 in the moving axial direction D1 in fig. 4), and the cross-sectional area of the passage 146 is smaller than a cross-sectional area of the accommodating groove 114 (indicated by a height H1 of the accommodating groove 114 in the moving axial direction D1 in fig. 4). As such, the channel 146 may be considered as a necked region between the receiving groove 114 and the resonant cavity 142.
Thus, in the present embodiment, the impact sound can be dispersed in the receiving groove 114 with a larger volume, and then concentrated through the passage 146 forming the necking region, and then emitted through the sound emitting hole 144 with a smaller cross-sectional area after generating resonance in the resonant cavity 142. The impact sound changes its frequency during the transmission of the above path, so the impact sound transmitted from the sound hole 144 is different from the impact sound generated by the magnetic element 120 impacting the side 112 of the housing 110. Preferably, the electronic device 100 can transmit a specific impact sound from the sound outlet hole 144, such as a low frequency and a heavy and heavy auditory sensation, but the invention is not limited to the frequency of the impact sound, which can be adjusted according to the requirement.
With the above design, in the present embodiment, the sound box structure 140 of the electronic device 100 is similar to a bass reflex cabinet (bass reflex cabinet), and the sound outlet 144 can be used as a reflex port. The impact sound can be resonated by the resonant cavity 142 to reduce the frequency before being transmitted out of the sound outlet 144.
In detail, in the present embodiment, the above components are preferably dimensioned to comply with Helmholtz resonance (Helmholtz resonance) principle commonly used for bass reflex enclosure design. That is, the frequency of the impact sound transmitted from the magnetic element 120 through the sound output hole 144 is proportional to the volume of the resonant cavity 142, the cross-sectional area of the sound output hole 144 (indicated by the width W2 in fig. 4) and the length of the sound output hole 144 (indicated by the height H4 in fig. 4), and the proportional relationship is the helmholtz formula:
in the above formula, f is the frequency of the impact sound transmitted from the magnetic element 120 through the sound output hole 144 (i.e. the frequency of the impact sound sensed by the user), c is the sound velocity, V is the volume of the resonant cavity 142, S is the cross-sectional area of the sound output hole 144, and L is the length of the sound output hole 144. According to the above formula, the frequency of the impact sound transmitted from the magnetic element 120 through the sound output hole 144 is proportional to the sectional area of the sound output hole 144, and inversely proportional to the volume of the resonant cavity 142 and the length of the sound output hole 144. Therefore, in order to reduce the frequency of the impact sound transmitted from the magnetic element 120 through the sound outlet 144, the cross-sectional area of the sound outlet 144 can be reduced according to the requirement, and the volume of the resonant cavity 142 or the length of the sound outlet 144 can be increased according to the requirement.
For example, in the present embodiment, the sound box structure 140 further includes an extension 148 extending from the sound outlet 144 to the resonant cavity 142. The impact sound is collected from the containing slot 114 through the passage 146 and transmitted out of the sound outlet hole 144 through the extension 148 after the resonant cavity 142 changes the frequency. Accordingly, in the above formula, the length of the sound emitting hole 144 (i.e. the parameter L of the above formula, which is represented by the height H4 in fig. 4) is the sum of the depth of the sound emitting hole 144 on the casing 110 (i.e. the thickness of the casing 110) and the length of the extension 148. In other words, the extension 148 helps to increase the length of the sound hole 144, so that the frequency of the impact sound transmitted from the magnetic element 120 through the sound hole 144 is reduced, and the impact sound is converted from a striking sound to a heavy and heavy auditory sensation. However, in other embodiments without the extension 148, the length of the sound emitting hole 144 is the depth of the sound emitting hole 144 on the casing 110 (i.e. the thickness of the casing 110), and the frequency of the impact sound can be changed by adjusting the sectional area of the sound emitting hole 144 or the volume of the resonant cavity 142. The present invention is not limited to the configuration of the extension 148, and can be adjusted according to the requirement.
Furthermore, in the embodiment, the sound box structure 140 for making the electronic device 100 generate the specific impact sound is disposed in the casing 110, and only the sound outlet 144 is exposed to the side 112 of the casing 110, so the design of the sound box structure 140 does not interfere with the operation that the casing 110 is combined with the combining portion 102a (shown in fig. 1) of the object 102 through the combining portion 130 and is connected to the object 102 through the side 112 by the magnetic element 102b attracted to the object 10 by the magnetic element 120, and does not affect the appearance of the electronic device 100.
In summary, in the electronic device of the present invention, the magnetic element is disposed in the accommodating slot of the housing, so that the housing is connected to or removed from the object by the side edge through the movement of the magnetic element in the accommodating slot, and the sound box structure is disposed in the housing, so as to change the frequency of the impact sound generated when the magnetic element moves in the accommodating slot and contacts the accommodating slot. Furthermore, the sound box structure comprises a resonant cavity communicated with the accommodating groove and a sound outlet communicated with the resonant cavity, so that the impact sound generated by the magnetic element can be transmitted out of the sound outlet after the frequency of the impact sound is changed by the resonant cavity from the accommodating groove. The frequency of the impact sound transmitted by the magnetic element through the sound outlet hole is in a proportional relation with the volume of the resonant cavity, the sectional area of the sound outlet hole and the length of the sound outlet hole. Accordingly, the electronic device of the invention can generate specific impact sound when being connected to another object.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
