Description

  The present invention relates to a sounding device such as a music box or a speaker, which is intended to improve appearance and sound quality, and is a sounding device having not only a function of listening to a pleasant sound but also a function as a decorative product.

  Music box devices and speaker devices are known as sounding devices. Generally, a music box device transmits a vibration of a music box body to a case surrounding the music box body and amplifies it to produce a loud sound. In general, the speaker device is composed of a sound source unit composed of a coil and a magnet, and a conical diaphragm made of paper, plastic, or the like.

  In a music box device, a box shape such as a jewel box or a cylindrical case is generally used for a portion where sound is reflected. On the other hand, music boxes with unique shapes, dolls, and various character types are also known. These are cases where a case is attached under a unique shape such as a doll, or a case is included in a character, and the case acts as a resonance body to amplify the vibration of the sound and produce a loud sound. It has become.

  However, with a music box device that generates sound by playing the scale plate simply by using the case as a resonator, the volume tends to be insufficient for a person to normally listen to. For this reason, conventionally, a music box device is known in which a cone is fixed to a sound source via a vibrating rod, and the sound is amplified to emit sound from the cone (see, for example, Patent Document 1). In a conventional music box device, sound can be magnified and radiated without using a special electric device.

  On the other hand, in the conventional speaker device, the diaphragm of the speaker is uniform and unattractive, and it is often covered with a coarse mesh cloth or net to make it look good and avoid direct contact with the eyes. In the field of music box devices, in order to improve the appearance, a music box device having a music box in a container such as a pot or basket that can use artificial flowers is known (for example, see Patent Document 2).

  The conventional music box device has a problem in that it is necessary to form the cone into a conical shape or a truncated cone shape, resulting in a high manufacturing cost. That is, in a music box device that amplifies the sound source emitted from the music box body with a cone or a truncated cone, the processing cost is high, and the price of the music box device itself is increased. In addition, it is difficult for a normal cone to amplify the sound as a soft and comfortable sound that depends on human hearing, and no effort has been made to make the sound amplifying part beautiful. Further, in the conventional music box apparatus, the sound-sounding portion is box-shaped, the conventional speaker cone is only conical, and the shape is not fun and cannot be easily attached and detached. For this reason, it was not easy to hear and compare sounds emitted from various materials.

  Embodiments will be described based on the following examples.

  FIG. 1 is a perspective view showing the overall configuration of a music box device as a sound producing device according to Embodiment 1 of the present invention, and FIG. 2 shows a side view thereof.

  As shown in the figure, the music box device 1 includes a sound generation mechanism 2 (music box sound generation mechanism), and the sound generation mechanism 2 has a rotating drum 3. The rotating drum 3 is attached to a base 5 as a frame through a support member 4, and a large number of pins 6 for playing a melody are planted on the outer periphery of the rotating drum 3. In addition, a spur gear or the like is attached to the input end of the main shaft of the rotary drum 3, and a spring 7 is disposed. The mainspring 7 is provided with a pinion gear 8 provided so as to rotate in conjunction with the central axis side, and the sub bar gear and the pinion gear 8 are engaged with each other. The mainspring 7 stores the rotation energy of the rotary drum 3 by the rotation of the handle 9.

  On the other hand, facing the outer periphery of the rotating drum 3, a musical scale plate 10 having a tip-like comb-like plate shape is attached to a main body frame 11 of the music box device 1. When the rotating drum 3 starts to rotate due to the stored energy of the spring 7, the tips of the comb-like plates of the musical scale plate 10 are played one after another by the pins 6 of the rotating drum 3. The mechanism portion is covered with a cover 17 to ensure safety.

  As the music box device 1, an electronic music box (an electronic music box sounding mechanism can be applied).

  Next, the main part of the music box apparatus 1 of the present invention will be described.

  The sound generated from the scale plate 10 as a sound source is transmitted as vibration energy to the main body frame 11, but the vibration of only the main body frame 11 has a relatively low volume as a sound appealing to human hearing. Further, although depending on the material of the main body frame 11 itself, the sound quality tends to be mechanical and inorganic, and it may be difficult to feel comfort.

  Therefore, in this embodiment, a plate-like paper as a paper member that is an article is detachably connected to the main body frame 11, and vibration energy is transmitted to the plate-like paper via a vibration medium, and the plate-like paper vibrates. The sound is emitted, the volume is increased, and the effect of producing a soft and comfortable sound is exhibited.

  In order to realize the above configuration, one end of a holding stand 12 formed of a metal wire as a vibration medium, for example, a wire material, a piano wire, or the like is fixed to the upper surface of the main body frame 11 with a screw 13. Further, the other end of the holding stand 12 is divided into two forks, and the tip of the holding stand 12 is bent into a bowl shape to form a flange portion 15. Further, a receiving portion 16 is formed at a position slightly below the intermediate portion of the holding stand 12, and the plate-like paper 14 is bent and held in a predetermined state between the collar portion 15 and the receiving portion 16 and held. Yes.

  By setting the distance between the upper edge side flange 15 and the lower edge side receiving part 16 of the holding stand 12 to an appropriate size, the curvature of the sheet paper 14 can be determined optimally. Moreover, by making the receiving part 16 slidable with respect to the holding stand 12, the sheet-like paper 14 can be curved to an arbitrary curvature radius (curvature changing means), and a sound volume adjusting function can be achieved. That is, if the radius of curvature of the sheet paper 14 can be changed, the volume generated from the sound source can be adjusted appropriately.

  The plate-like paper 14 has a plane that intersects the plane (horizontal direction) of the scale plate 10 (orthogonal: vertical direction) and intersects the slit formation direction of the scale plate 10 (orthogonal: the center of the drum 3). (Direction along the axis). For this reason, the vibration of the scale plate 10 is reliably transmitted.

  The sheet paper 14 will be described.

  As the plate-like paper 14, Western paper or Japanese paper is used. In particular, in the case of Japanese paper, it is preferable to use Japanese paper with good sound and bast fibers such as ganpi, strawberry, banana, kenaf, pinia. Japanese paper using these bast fibers has the effect of producing a soft and comfortable sound when the sound is transmitted. Note that even paper can produce a much softer sound than metal or plastic vibrating members.

  Since the sheet paper 14 can be freely removed, it can be exchanged according to the surrounding atmosphere, season, etc. by preparing multiple types of sheet paper 14 on which pictures and pictures of landscapes, plants, birds, etc. are printed. It can be used for a large number of scenes or as an original ornament. In addition, by preparing a plurality of types of plate-like paper 14 with torn pictures, pressed flowers, etc., it is possible to create value as an ornament or a room interior. Furthermore, aroma oil, a fragrance | flavor, etc. may be soaked in the plate-shaped paper 14, and a synergistic effect with an olfaction may be acquired. It can also be used as a store display or a restaurant table menu.

  It is also possible to illuminate the sheet paper 14 with illumination means. By using the lighting device, for example, soft light can be obtained through Japanese paper, and the value as a decorative product can be further increased.

  Further, by adding or coating titanium oxide on the sheet-like paper 14 or the holding stand 12 as an article, the color is finished beautifully and the deodorizing effect of the photocatalyst can be expected. Furthermore, the music box device 1 is placed at the entrance, etc., and is configured to emit a beautiful tone by detecting with a sensor when a visitor passes by or touches it (control means), and when the visitor passes A timbre can be greeted by visitors. In addition, by attaching a light source such as a light bulb or EL (electroluminescence) and interlocking with the illumination, a synergistic effect of sound, light, and shape can be given more presence, and visitors can be welcomed gently.

  Therefore, in the above-described first embodiment, by using a paper surface made of western paper or Japanese paper as a sound source medium, it is possible to make it an object of aesthetic appreciation as a decorative body and a softness of sound that has not existed in the past. It can be a very useful sounding device that can be developed.

Since the configuration of the sound generation mechanism 2 is the same as that of the first embodiment shown in FIGS. 1 and 2, the same reference numerals are given and duplicate descriptions are omitted. Example 2 shows an example of a sounding device in which an artificial flower portion as an article is resonated by a music box device.

  The vibration energy emitted from the sound generation mechanism 2 of the music box device is transmitted to the wire support 21 via the screw 13 as a vibration medium, and is transmitted to the Japanese paper decoration body 24 including the flowers 22 and the leaves 23 via the wire support 21. The decorative body 24 is made to resonate.

  More specifically, one end of a wire post 21 formed of a metal wire, for example, a wire material, a piano wire, or the like is fixed to the upper surface of the main body frame 11. An insertion socket 25 is provided at the other end of the wire support 21, and a branch / stem metal wire 26 to be a stem of the flower 22 and the leaf 23 is inserted into the insertion socket 25. The branch / stem metal wire 26 is colored with Japanese paper or cloth, but the joints of the flower 22 and the leaf 23 are directly connected to each other, and the vibration of the sound is generated by combing the Japanese paper or cloth. It can be communicated without losing energy.

  The artificial flower portion 22 and leaves 23 will be described.

  Flowers 22 and leaves 23 use Japanese paper or cloth. In particular, in the case of Japanese paper, it is preferable to use Japanese paper with good sound and bast fibers such as ganpi, strawberry, banana, kenaf, pinia. Japanese paper using these bast fibers has the effect of producing a soft and comfortable sound when the sound is transmitted. Also, when using a cloth, the sound is improved by hardening with glue, curving with a baking iron or the like, and giving tension to the surface. Furthermore, it is also possible to wrap the whole artificial flower portion in a bouquet shape with cellophane or Japanese paper. At this time, if the material is hard and the material is easy to resonate, and the wire strut 21 and the insertion socket 25 are firmly bound with a ribbon or the like, the sound is further improved.
