  In a wireless microphone device, a loud sound can be heard from a speaker when the housing of the device is hit. For example, when wearing a metal ring, mechanical vibration noise enters the microphone device when it comes into contact with a metal microphone housing. As a result, an unfavorable sound is produced at a loud volume from the speaker. This also causes damage to the amplifier and speakers.

  Also, the microphone becomes unsanitary when used for a long time. Not only is it unsanitary, it also looks dirty. This is a big problem in karaoke stores where many people change and use. The entire wireless microphone device is not hygienic, but what matters here is the upper / lower exterior of the hand. The most dirty part is the microphone head, which becomes dirty when saliva or solids fly from the mouth when singing, and is generally handled by alcohol disinfection, but this is outside the scope of the present invention.

  Many recesses are generated in the upper part of the exterior and the lower part of the exterior due to hand sweat. This is believed to be due to corrosion of the aluminum. When this occurs, the alumite on the surface is peeled off and it is dirty and unpleasant.

  In addition, when the design of characters, advertisements, etc. is given to the casing of the wireless microphone device, that is, the upper part of the exterior and the lower part of the exterior, when the rechargeable battery arranged in the lower part of the exterior is replaced, It may happen that the pattern is slightly shifted at the lower part of the exterior. A female screw is formed at the lower part of the exterior, and it is fixed by fitting with the external thread at the upper part of the exterior, but if the exterior lower part is tightened or if another exterior lower part is used, the design position will be It will shift at the top / bottom. This is also a problem in use.

  The present invention is intended to solve the problems of such a conventional configuration, such as mechanical vibration noise, unsanitary conditions, generation of recesses due to hand sweat, etc., and the pattern slightly deviates. An object of the present invention is to provide a wireless microphone device that can solve these problems simultaneously.

  In the present invention, in order to achieve the above object, in a wireless microphone device having a sound signal input unit, a microphone head unit, a power switch unit, an upper part and a lower part made of aluminum, and a signal radiating part, A film for attenuating the sound signal is disposed in the lower part excluding the power switch part and the signal radiating part, and this film is adhered to the upper part and the lower part of the exterior by intermolecular force.

The operation of the above solution is as follows.
Vibrations (noise) and the like that enter the interior due to the vibration of the housing of the wireless microphone device are blocked by a film that absorbs sound signals. In addition, since the upper part and the lower part of the exterior are covered with a film, it can be replaced if it gets dirty and can be used in a sanitary manner. In addition, when a film is present, a design image, characters, and the like can be displayed and decorated, so that it can be comfortably used in a good-looking state. Furthermore, it can be used in a gorgeous mood. Of course, it can also be used for advertising. In addition, if there is a rechargeable battery storage part in the lower part of the exterior, it is necessary to remove the lower part of the exterior, but in the present invention, since the film is only attached by intermolecular force, it can be easily peeled off and attached again. The rechargeable battery can be easily inserted and removed. Moreover, since it is not necessary to divide the film between the upper part of the exterior and the lower part of the exterior, design images and characters are not shifted.

  Since the present invention is configured as described above, the following effects can be obtained. That is, it is possible to reduce vibration noise (noise) that enters the inside as vibration of the housing. It prevents unsanitary and prevents corrosion caused by hand sweat. Also, the pattern will not be shifted. A wireless microphone device that realizes these simultaneously can be provided.

It is a perspective view for demonstrating the wireless microphone apparatus of this invention, and is a figure of the state which peeled off the film 7 partially. It is a disassembled block diagram of the conventional wireless microphone apparatus. It is an expanded view of the film which attenuates a sound signal.

Embodiments of the present invention will be described based on examples with reference to the drawings.
A sound signal input unit 6 that converts a sound signal into an electrical signal, a microphone head unit 1 that covers the sound signal input unit 6, a power switch unit 4, an exterior upper part 2 and an exterior lower part 3 made of aluminum covering the sound signal processing circuit board, In the wireless microphone device having the signal radiating unit 5 that emits infrared rays and radio waves, a film 7 for attenuating the sound signal is provided on the exterior upper part 2 and the exterior lower part 3 except for the power switch part 4 and the signal radiating part 5. The film 7 is attached to the exterior part by intermolecular force. The thickness of the film 7 is desirably 0.1 mm to 0.5 mm so that the conventional handling such as insertion into a charger can be performed. FIG. 1 is a perspective view for explaining a wireless microphone device of the present invention, and shows a state in which a film 7 is partially peeled off.

  The film 7 has a hole 8 for a power switch part, which is attached and fixed to the upper part of the exterior and the lower part of the exterior. In this embodiment, vinyl chloride is used as the film 7. This film is further provided with an adhesive (glue) that adheres with an intermolecular force instead of a binding adhesive. The film surface is printed with acrylic, and catch copy letters, barcodes, and photographs are printed. In addition, when thick printing is performed by gloss printing or the like, an effect such as a band filter can be given to mechanical vibration noise, or simply decorativeness can be given.

  Since the film 7 and the exterior upper part 2 and the exterior lower part 3 are in close contact with each other, vibration (noise) entering the interior is reduced. Moreover, since it has the hand, ie, the exterior upper part 2 and the exterior lower part 3 vicinity is covered with the film 7, when it gets dirty, it can be replaced | exchanged and it can use now hygienically. It can also be used for other purposes such as advertising and barcodes, and can be used in the gorgeous mood inherent in karaoke. Moreover, since there exists a rechargeable battery storage part in the exterior lower part 3, it is necessary to remove an exterior lower part, but in a present Example, a rechargeable battery can be replaced | exchanged easily by peeling a film. Moreover, since it is not necessary to divide the film between the upper part of the exterior and the lower part of the exterior, the design image and characters are not shifted.
