Field of the Invention The present invention relates to a portable case for a small sound generating device, and more particularly to a portable case having a window with a breathable ultrathin waterproof film. The present invention relates to a waterproof case for a sound generating device.

2号公報等参照)。2. Description of the Related Art As is well known, a general plastic film or a bag made of this is highly preferable as a waterproof film or a waterproof case because of its high gas barrier property and low moisture permeability. I am involved in everyday life. For example, a sound generating device (for example, a radio, a tape recorder, etc.) is housed in a waterproof case (see, for example, Japanese Utility Model Laid-Open No. 59-143131), or a speaker or buzzer portion of the radio. Only the part is covered with a waterproof film (Japanese Utility Model Publication No. 58-19890, Japanese Utility Model Publication No. 1-2230).
No. 2).

ムで覆うことが示されている。The waterproof film will be described. In the above-cited Japanese Utility Model Publication No. 1-23022, when a loudspeaker opening is covered with a waterproof film and a speaker is provided in the opening through a packing, a minute projection is formed on the periphery of the opening where the packing hits. It is shown that a line is provided, and a waterproof film is provided between the periphery and the packing while providing tension, and waterproofing and deterioration of sound quality are prevented. On the other hand, the above-mentioned Japanese Utility Model Publication No. 58-19890 discloses that the back of a rainwater-penetrable speaker is covered with a breathable waterproof film.

あった。Therefore, it is conceivable to use the breathable waterproof film shown in the latter publication instead of the waterproof film covering the opening of the speaker shown in the former publication. However, when a breathable waterproof film is used in the opening of the speaker, the breathable waterproof film has extremely low mechanical strength, which makes it difficult to cover the film while tensioning the film and often breaks it. There was a problem.

ングで挟んで固着すればよい、ということに気付いた。Therefore, the inventors of the present invention have made earnest and trial-and-error attempts to solve such a problem. As a result, the breathable ultra-thin waterproof film does not deteriorate the sound quality even if the film is not tensioned. However, in order to allow the curtain vibration due to the sound, it has been found that the film ears may be sandwiched and fixed in advance by a pair of spacer rings.

ない。It is known that a breathable waterproof film is sandwiched by a pair of spacer rings inside the buzzer (see Japanese Utility Model Laid-Open No. 62-3188). Although the buzzer housing covers the outer surface of the waterproof film, the sound-generating component is directly located on the inner surface of the waterproof film, which may damage the breathable ultra-thin waterproof film when mounting the sound-generating component. Yes, it cannot be adopted.

を大にせず、小型音響発生機器に好都合となる。According to the present invention, a breathable waterproof film is provided on the outer surface side of the porous window zone of the waterproof case body, and the porous film protection is provided on the outer surface side of the waterproof film. Since a cover plate is provided and an edging ring sandwiched by a pair of spacer rings is provided at the entire ear portion of the waterproof film, it is an extremely thin waterproof film with low mechanical strength that allows ventilation. It is possible to prevent damage during film mounting work and use of audio equipment. Moreover, since the film curtain vibration due to the sound is allowed by the thickness of the pair of spacer rings, the deterioration of the sound quality of the audio equipment can be prevented. Furthermore, since it is composed of a waterproof case body, a waterproof film sandwiched between spacers having a thickness that allows curtain vibration, and a film protective cover plate, the overall thickness dimension is not increased, It is convenient for small sound generators.
