Efficiency is low, pollution environment, and fixed effect is bad.
Utility model content
The purpose of this utility model is to provide a kind of passive basin apparatus and audio amplifier it is intended to solve driven disc in prior art
Using glue fixing when operation is numerous and diverse, low production efficiency, pollution environment, and the bad problem of fixed effect.
This utility model is achieved in that and provides a kind of passive basin apparatus, including the housing with chamber and set
In the driven disc of described within the chamber, also include a compression piece, described chamber bottom has an opening of chamber described in insertion, described open
The periphery of mouth is provided with annular groove, and described driven disc neighboring is provided with the ring side of projection, and the edge on described ring side is provided with
The bulge loop in described annular groove can be stuck in, described compression piece pressure and is fixed on described on described driven disc by securing member
Within the chamber.
Alternatively, the vertical section of described annular groove is in fall " v " font structure, and the vertical section of described bulge loop is in " v " font
Structure.
Alternatively, described compression piece is annular in shape, and described securing member is screw, described annular piece pass through screw with described
Chamber bottom is fixedly connected.
Alternatively, the periphery of described annular piece is provided with multiple engaging lugs, each described engaging lug be provided be available for described
The through hole that screw passes through, the diapire of described chamber is provided with screw corresponding with described through hole.
This utility model additionally provides a kind of audio amplifier, including casing and loudspeaker, also includes above-mentioned passive basin apparatus.
In this utility model, the ring side of the driven disc bulge loop of setting up cooperate clamping corresponding with chamber opening with
Annular groove, during assembling, bulge loop is stuck in annular groove, so so that driven disc is tightly sealed with opening, strengthens driven disc
With the sealing effectiveness of chamber, simultaneously by compressing the pressuring action of piece it is ensured that driven disc is firmly secured within the chamber, prevent it from taking off
Fall；Said structure is simple, and easy to assembly, improve production efficiency to environment, and will not ensure that consolidating of driven disc
Determine intensity, and, using said structure under the premise of the sealing realizing driven disc and fixing, can correspondingly reduce the width on ring side
Degree, thus ensure the low-frequency effect of audio amplifier.

Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only in order to explain this
Utility model, is not used to limit this utility model.
The passive basin apparatus providing referring to figs. 1 to Fig. 5, this utility model embodiment, including the housing 10 with chamber 11
And the driven disc 20 in chamber 11, also include a compression piece 30, chamber 11 diapire has the opening 12 of insertion chamber 11,
The periphery of opening 12 is provided with annular groove 13, and driven disc 20 neighboring is provided with the ring side 21 of projection, described ring side 21
Edge is provided with the bulge loop 22 being stuck in annular groove 13, and compression piece 30 is pressed on driven disc 20 and fixing by securing member 40
In chamber 11.
In the present embodiment, set up the clamping that cooperates the ring side 21 of driven disc 20 is corresponding with chamber 11 opening 12
Bulge loop 22 and annular groove 13, during assembling, bulge loop 22 is stuck in annular groove 13, so so that driven disc 20 and opening 12 quilt
