  However, in the conventional speaker, a light emitting diode and a light guide must be provided below the dust cap and on the back side of the diaphragm, which causes a problem that the structure and processing become complicated and the manufacturing cost increases. . In addition, when transmitting light to the diaphragm, it is necessary to use a speaker unit using a transparent material such as polypropylene resin for the diaphragm, and for a speaker using a conventional opaque material for the diaphragm, There was a problem that this invention could not be applied.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a speaker device that can produce an effect by sound and light even when a speaker unit having an opaque diaphragm is used without making the structure and processing complicated.

  The present invention has the following configuration as means for solving the above problems.

  In this configuration, a plurality of reflection / transmission pieces for reflecting light and a plurality of reflection / transmission pieces for transmitting light are provided facing the diaphragm of the speaker unit, and light is emitted from the light source to the plurality of reflection / transmission pieces. . When an audio signal is input to the speaker unit from the outside, the diaphragm vibrates according to the audio signal, the vibration is transmitted to the reflection / transmission piece using air as a medium, and the reflection / transmission piece vibrates. Since the reflection / transmission piece vibrates and reflects or transmits light from the light source, the light from the light source depends on the vibration of the diaphragm, that is, on the sound pressure and frequency of the sound emitted from the speaker unit. The light is irradiated in various directions while changing the direction. Therefore, the structure and processing are not complicated, and even if a speaker unit with an opaque diaphragm is used, it is possible to produce sound and light. It is also easy to process an existing speaker device into the speaker device of the present invention.

An enclosure to which the speaker unit is attached;
A port for guiding an air flow generated by vibration of the diaphragm to the outside of the enclosure;
A plurality of reflection / transmission pieces that are provided so as to vibrate facing the port and reflect or transmit light; and
A light source for irradiating the reflective / transmissive piece with light;
It is provided with.

  In this configuration, a plurality of reflection / transmission pieces that reflect light and a plurality of reflection / transmission pieces that transmit light are provided to face the port, and light is emitted from the light source to the plurality of reflection / transmission pieces. When an audio signal is input to the speaker unit from the outside, the diaphragm vibrates according to the audio signal, and an air flow generated by the vibration is guided to the outside of the enclosure by the port. Vibrate. Since the reflection / transmission piece vibrates and reflects or transmits light from the light source, the light from the light source depends on the vibration of the diaphragm, that is, on the sound pressure and frequency of the sound emitted from the speaker unit. The light is irradiated in various directions while changing the direction. Therefore, the structure and processing are not complicated, and even if a speaker unit with an opaque diaphragm is used, it is possible to produce sound and light.

  In this configuration, the air inlet of the storage case that stores the plurality of reflection / transmission pieces is connected to the port. The reflection / transmission piece is made of a material that reflects light or transmits light, and has a weight that scatters inside the storage case due to the pressure of air flowing in from the port (for example, aluminum foil or cellophane is finely cut. Etc.) is put in a storage case, and light is emitted from the light source to the storage case. When an audio signal is input to the speaker unit from the outside, the diaphragm vibrates according to the audio signal, and an air flow generated by the vibration is guided to the outside of the enclosure by the port, and this air flow is introduced into the storage case. Therefore, the reflection / transmission piece is scattered. Therefore, the reflection / transmission piece reflects or transmits the light from the light source while being scattered, so that the light from the light source is irregularly reflected by the reflection / transmission piece or the transmitted light changes depending on the scattering state. As a result, the structure and processing are not complicated, and it is possible to produce sound and light even when a speaker unit having an opaque diaphragm is used.

  According to the present invention, the reflection / transmission piece and the reflection / transmission piece irradiated with light are configured to vibrate or scatter according to the vibration of the diaphragm of the speaker unit. For this reason, the reflective transmission piece or the reflection transmission piece scatters light or changes the direction of the transmitted light to irradiate light in various directions, and depending on the loudness and frequency of sound emitted from the speaker unit. Thus, the light irradiation direction can be changed. Thereby, the effect by the light according to the sound emitted from a speaker unit can be performed. Moreover, even if a speaker unit with an opaque diaphragm is used without making the structure and processing complicated, it is possible to produce sound and light.

  Hereinafter, details of the speaker device according to the first embodiment of the present invention will be described. FIG. 1 is a schematic configuration diagram of a speaker device according to a first embodiment of the present invention. FIG. 1A is a side sectional view and a front view showing a configuration in which a reflection unit is vibrated by vibration of a diaphragm of a speaker unit. FIG. 1B is a rear view and a side cross-sectional view showing a configuration in which the reflection unit is vibrated by the air flow from the port. FIG. 1C is a side cross-sectional view illustrating a configuration in which the reflection unit is vibrated by the vibration of the diaphragm of the speaker unit and the air flow from the port.

  As shown in FIG. 1A, the speaker device 1 has a speaker unit 13 attached to the front side of the enclosure 11. In addition, a vibration unit 21 is provided in front of the speaker unit 13 so as to face the diaphragm 15 of the speaker unit 13.

It is attached. The vibration unit 21 is suspended so that a plurality of reflection / transmission pieces 27 can vibrate in front of the speaker unit 13 like warmth or mobile. As the reflection / transmission piece 27, a material that can produce an effect by light, such as a material that reflects light, a material that transmits light, or a material that splits light, or a surface-processed material is used. Different ones are randomly arranged. As the reflection / transmission piece 27, for example, a metal piece, a colored film, a prism, or the like may be used.

  A light (light source) 31 is attached to the front side of the enclosure 11 below the vibration unit 21. The light 31 irradiates the plurality of reflection / transmission pieces 27 of the vibration unit 21 with light. By using the light 31 whose light emission color changes at a predetermined time interval, it is possible to further improve the effect of light.

  In the speaker device 1, when an audio signal (electrical signal) is input to a signal line (not shown), the diaphragm 15 of the speaker unit 13 vibrates to emit sound. The vibration (sound pressure) of the diaphragm 15 is transmitted to each reflection / transmission piece 27 of the vibration unit 21 using air as a medium, and each reflection / transmission piece 27 vibrates. At this time, since the light 31 irradiates the reflection / transmission piece 27 with light from below, the reflection / transmission piece 27 causes light to be irregularly reflected or the direction in which the light is transmitted changes. Further, the vibration state of each reflection / transmission piece 27 differs depending on the volume and frequency of the sound emitted from the speaker unit 13. Therefore, it is possible to produce an effect of changing the movement of light according to the sound emitted from the speaker unit 13.

  Further, since the light 31 is irradiated from below the vibration unit 21, the light transmitted through the reflection / transmission piece 27 and the reflected light can be applied to the ceiling and surrounding walls of the room, and the atmosphere of the entire room is raised. be able to.

  The vibration unit 21 is not limited to a shape such as a warm bath or a mobile, and may be of any other shape as long as the vibration of the diaphragm 15 is transmitted to the plurality of reflection / transmission pieces 27 via air. good. For example, you may make it provide the net | network (transparent is suitable) which attached the some reflective transmission piece 27 in the front surface of the speaker unit 13. FIG. In this case, since the entire net vibrates due to the sound emitted from the speaker unit 13, the light according to the volume and frequency of the sound can be produced by the light from the light 31.

  Next, a case where a speaker device having a port in the enclosure is used will be described. In the speaker device 3 shown in FIG. 1B, a speaker unit 14 is attached to the front side of the enclosure 12. Further, a port 17 is provided behind the speaker unit 14 at a position lower than the mounting position of the speaker unit 14. Since the port 17 guides the air flow generated by the vibration of the diaphragm 16 of the speaker unit 14 to the outside of the enclosure 12, an air flow is generated in front of the port 17.

  In the present invention, the vibration unit is vibrated using this air flow. That is, a support plate 24 extending rearward from the upper surface of the enclosure 12 of the speaker device 3 is provided, and the vibration unit 22 is attached to the support plate 24. The vibration unit 22 has the same configuration as that of the vibration unit 21, and a plurality of reflection / transmission pieces 28 are attached to a plurality of transparent threads 26 having one end connected to the support plate 24 and the other end being free, respectively, at arbitrary intervals. It is a thing. In the vibration unit 22, a plurality of reflection / transmission pieces 28 face the port 17 and are suspended so as to be able to vibrate in front of the port 17, like warmth and mobile. As the reflection / transmission piece 28, similar to the reflection / transmission piece 27, one that reflects, transmits, or disperses light is used.

  As shown in FIG. 1B, by providing the vibration unit 22 in front of the port 17, the plurality of reflection / transmission pieces 28 can be vibrated by the air flow guided from the port 17 to the outside of the enclosure 12. At this time, similarly to the configuration shown in FIG. 1A, by providing the light 32 that irradiates light to the plurality of reflection / transmission pieces 28, the light is irregularly reflected by the reflection / transmission pieces 28, or Radiation direction changes. Further, the air flow guided from the port to the outside differs depending on the volume and frequency of the sound emitted from the speaker unit 14. Therefore, it is possible to produce an effect in which the intensity of the light emission direction and the degree of change are increased or decreased in accordance with the sound emitted from the speaker unit 14.

  In FIG. 1B, the case where the vibration unit 22 is provided at a position facing the port 17 is described. However, the present invention is not limited to this, and a speaker such as the speaker device 4 shown in FIG. The vibration unit 21 may be provided at a position facing the unit 14.

Further, a port 17 that guides an air flow generated by the vibration of the diaphragm 15 of the speaker unit 13 to the outside of the enclosure 12 is formed behind the enclosure 12. A storage case 41 is attached to the rear side of the enclosure 12 above the port 17. The storage case 41 has a wall surface formed of a transparent material, and stores particulate reflective / transmissive pieces. The air inlet 43 of the storage case 41 is connected to a part of the port 17, and a part of the air flow guided to the outside from the port 17 is guided into the storage case 41. The reflection / transmission small piece 29 accommodated in the storage case 41 is made of a material that reflects or transmits light or a material processed so as to have such characteristics. Further, as the reflection / transmission small piece 29, a small and light weight is used so that when the air flow from the port 17 is introduced into the storage case 41, the inside of the storage case 41 is scattered. To do. For example, aluminum foil or cellophane that has been finely cut may be used.

  The air inlet 43 connecting the storage case 41 and the port 17 is provided with a mesh (not shown) of finer mesh than the reflection / transmission small piece 29 so that the reflection / transmission small piece 29 does not come out of the storage case 41. .

A part of the air flow generated by the vibration of the diaphragm 16 of the speaker unit 14 is guided from the port 17 leading to the outside of the enclosure 12 through the air inlet 43 into the storage case 41. As a result, the plurality of reflection / transmission pieces 29 in the storage case 41 are scattered and reflect or transmit the light emitted from the light 32, so that the reflection / transmission pieces 29 are changed according to the amount of air guided from the port 17. The scattering state of changes. The amount of air guided from the port 17 to the air inlet 43 varies depending on the volume and frequency of the sound emitted by the speaker unit 14. Therefore, the scattering state of each reflection / transmission piece 29 can be changed according to the sound emitted from the speaker unit 14, and the light effect can be changed according to the sound.

  Note that the storage case 41 is not limited to the case where the air inlet 43 is connected to a part of the port 17. For example, the speaker case 6 shown in FIG. 43 may be connected to the entire port 17. In the case of such a configuration, it is necessary to provide the storage case 41 with an air outlet 44 to which a mesh of eyes smaller than the reflection / transmission piece 29 is attached.

  Further, as in the speaker device 7 shown in FIG. 2C, not only the storage case 41 is provided at the rear of the enclosure 12, but the diaphragm 16 of the speaker unit 14 is opposed to the diaphragm 16 as in FIG. Of course, it is also possible to provide the vibration unit 21.
