Abstract

(57) [Summary] [Purpose] The objective is to improve the waterproof structure of the speaker mounting part that is mounted on the case of a wireless communication device. [Structure] An elastic packing 3 is interposed between a speaker 2 and a case 1 in which the speaker 2 is mounted.
The elastic packing 3 has a rib 3a projecting toward the speaker 2 on the outer peripheral side, and a kamaboko-shaped rib 3b projecting on the case 1 side to be mounted on the inner peripheral side. When 2 is attached to the case 1, the rib 3b of the elastic packing 3 is pushed toward the speaker side and the rib 3a on the outer diameter side wraps the mounting surface of the speaker 2 to form a waterproof structure.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a waterproof structure of a speaker mounting portion of a portable wireless communication device or audio equipment.

[0002]

[Prior art]

 Conventionally, in the case of a portable wireless communication device or an audio device used outdoors, the speaker was attached in consideration of waterproofness. FIG. 3 is a sectional view showing a waterproof structure of a conventional speaker mounting portion.

The figure will be described. Reference numeral 1 is a case of a wireless communication device or the like. 2 is a speaker and 4 is an O-ring. In this mounting structure, an O-ring 4 is put in contact with the inside of the mounting side of the speaker 2. When the O-ring 4 is attached to the speaker 2, the O-ring 4 has a thickness that protrudes from the mounting surface of the speaker 2 so that the O-ring 4 can exhibit sufficient elasticity even when the speaker 2 is completely pressed and attached. Is necessary. Moreover, the O-ring 4 as a whole is crushed on average by the pressure of the speaker 2, so that the waterproof effect is obtained. Therefore, it is necessary to apply a sufficient pressure evenly between the speaker 2, the O-ring 4 and the case 1 to be attached.

[0004]

[Problems to be solved by the device]

 In the waterproof structure using the O-ring of the speaker mounting portion according to the related art, it is necessary to apply strong pressure from the speaker side to press the O-ring. Further, if this pressing force is not applied evenly, sufficient waterproofness cannot be obtained. An object of the present invention is to provide a mounting structure that requires less pressing force and has a high waterproof effect.

[0005]

[Means for Solving the Problems]

 In order to obtain the waterproof effect of the speaker mounting part, elastic packing is interposed between the speaker and the case to be mounted. The elastic packing has a shape in which ribs are protruded on the outer peripheral side on the speaker side and on the inner peripheral side on the case side to be mounted. The ribs on the radial side are in close contact with the outer periphery of the speaker mounting surface, and the ribs on the inner diameter side are pressed and bent toward the speaker side by the mounting surface of the case to be mounted, so that waterproofness is achieved.

[0006]

[Action]

 When the speaker is attached, the rib on the inner diameter side of the elastic packing comes into close contact with the outer periphery of the mounting surface of the speaker, and by pressing the mounting surface of the speaker, the rib on the inner diameter side of the elastic packing becomes flat on the case surface to be mounted. When pressed up, the ribs are deformed so that they are bent toward the speaker. For this reason, there is no risk of water entering from either the case side where the elastic packing is attached or the speaker side.

【Example】

 FIG. 1 is a block diagram showing a structure for mounting a speaker according to the present invention. In the figure, 1 is a case of a wireless communication device, 2 is a speaker, and 3 is elastic packing. This elastic packing 3 has a shape different from that of a packing inserted between ordinary members. That is, the protruding rib 3a provided on the outer peripheral edge of the elastic packing for closely contacting the outer peripheral portion of the mounting surface of the speaker 2 and the inner peripheral edge protruding toward the case 1 to be mounted. It is an elastic packing having a structure including a kamaboko-shaped rib 3b.

To mount the speaker 2, first, the elastic packing 3 is attached to the speaker 2. In this state, the speaker is mounted on the speaker mounting portion of the case 1 using a screw or a mounting bracket (not shown). The rib 3b needs a force enough to push and bend it toward the speaker side, but this pushing force can be set with a smaller pressure than the conventional O-ring type.

FIG. 2 is a sectional view showing a state where the speaker according to the present invention is mounted, FIG. 2 (a) is a sectional view showing a state where elastic packing is mounted on the speaker, and FIG. 2 (b) is a case of the speaker. It is a sectional view showing the state where it was attached to. The figure will be described.

FIG. 2A shows a first step for mounting the speaker 2 on the case 1. In the figure, 3a is a rib provided on the outer peripheral edge of the elastic packing 3, and 3b is a semi-cylindrical rib provided on the inner peripheral edge of the elastic packing 3. Using the elasticity of the elastic packing 3, the elastic packing 3 is stretched and slightly attached to the speaker 2. Therefore, the ribs 3a of the elastic packing 3 are closely contacted with the outer peripheral portion of the speaker 2 to enhance waterproofness with the speaker 2.

FIG. 2B is a cross-sectional view showing a state in which the speaker 2 is attached to the case 1, and FIG. 2B will be described. In the state where the elastic packing 3 is attached to the speaker 2 in FIG. 2A, the speaker 1 is attached to the case 1 with a screw or a mounting bracket (not shown). At this time, the hook-shaped rib 3b of the elastic packing 3 is pushed by the mounting surface of the case 1 to make the case side flat, and the rib 3b on the inner diameter side is pressed by the speaker 2 side so that it is bent toward the speaker side. Then install. Therefore, when the rib 3b on the inner diameter side of the elastic packing 3 is pressed and bent by the mounting surface of the case 1 to be mounted, the mounting surface of the speaker 2 is deformed into a shape wrapping with the rib 3a on the outer diameter side. Therefore, due to the elastic packing 3, a sufficient waterproof effect can be obtained on both the speaker 2 side and the case 1 side.

[0012]

[Effect of device]

 According to the present invention, the waterproof structure of the speaker mounting portion is a structure of elastic packing provided between the speaker and the case of the wireless communication device, etc., and a rib is projected toward the speaker side at the outer peripheral edge of the elastic packing. Since the inner peripheral edge has a hook-shaped rib protruding toward the case to be mounted, the outer diameter rib is in close contact with the outer periphery of the speaker mounting surface, and the inner diameter rib is The mounting surface of the mounting case pushes it toward the speaker side and the two ribs wrap the speaker's mounting surface to create a waterproof structure that requires less force to press the elastic packing, and also provides a complete waterproof effect. can get.
