The size in hole and position are engaged, and the insertion circle is embedded into the inner side of the first back-up ring, and the salient point is snapped onto in through hole.
Preferably, circular arc lid is formed in the upper plane of the insertion circle, is offered on the overhead surface of the circular arc lid
Six keynote holes being angularly distributed and six kidney-shaped consonant holes being angularly distributed, six keynote holes and six kidney-shapeds are auxiliary
The spaced distribution of sound hole, each angulation between kidney-shaped consonant hole and two adjacent keynote holes are equal.
Preferably, the overhead surface center of the circular arc lid is further opened with centre bore.
Compared with prior art, the utility model has the advantage of：The sound transmission of loudspeaker in itself is limited in one's ability and is in
Unordered state, in some special use environments, it is necessary to loudspeaker are put into sound intracavitary and is arranged and is optimized, just can guarantee that
Loudspeaker can be effectively good performance effect；Existing loudspeaker sound chamber positions cumbersome and easy loosening in assembling, loudspeaker performance and
Effect can not play well, and using effect is not good enough.The design of the utility model salient point and through hole, loudspeaker sound chamber can be caused in group
Positioned quickly and easily during dress, the design of screwed hole and rectangular channel can prevent bottom and top cover from relatively rotating, so as to prevent pine
Dynamic, through hole, centre bore, keynote hole and kidney-shaped consonant hole can preferably bring the performance of loudspeaker and effect into play, improve
Using effect.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model；
Fig. 2 is the rear structure figure of bottom of the present utility model.
Embodiment
As shown in Fig. 1~2, a kind of miniature moving-coil loudspeaker sound chamber, including bottom 1 and top cover 2；The upper horizontal edge of bottom 1
Form the first back-up ring 11 upwards, offer screwed hole 14 and through hole 15 on the circumference side of the first back-up ring 11, screwed hole 14 with
Formed angle is 180 degree between through hole 15；The upper planar central of bottom 1 forms the second back-up ring 13 upwards；The upper of bottom 1 is put down
Be further opened with face 12 through holes being angularly distributed, 12,12 through holes 12 be located at the first back-up ring 11 and the second back-up ring 13 it
Between；Bottom 1 is fixedly arranged above top cover 2, and collar 27 is formed on top cover 2, insertion is formed downwards on the lower plane of collar 27
Circle 21, insertion are enclosed on 21 circumference side and form rectangular channel 22 and salient point 27；Rectangular channel 22 and between salient point 27 it is formed
Angle is 180 degree, and the size of salient point 27 and position match with the size of through hole 15 and position merges the mutual clamping of energy, by top cover 2
On the inner sides that are embedded into the first back-up ring 11 of insertion circle 21, top cover 2 is then slowly rotated, until salient point 27 snaps onto through hole 15
In, then stop the rotation so as to complete to position, then twisted from outside to inside using supporting screw and wear screwed hole 14 and be inserted into top cover 2
On rectangular channel 22 in, so as to prevent top cover 2 from continuing to rotate；Circular arc lid 23, circular arc lid are formed in the upper plane of insertion circle 21
Offer six keynote being angularly distributed holes 24 and six kidney-shaped consonant holes 25 being angularly distributed on 23 overhead surface, six
Individual keynote hole 24 and six 25 spaced distributions of kidney-shaped consonant hole, each kidney-shaped consonant hole 25 and two adjacent keynote holes 24
Between angulation it is equal；The overhead surface center of circular arc lid 23 is further opened with centre bore 26.In use, by loudspeaker bottom
Portion is embedded in the second back-up ring 13 and causes the vibrating membranes of loudspeaker upward then be fastened top cover 2；Loudspeaker send sound
When, 12 through holes 12 make the air-flow of bottom 1 feed holding straight line and in order unobstructed, centre bore 26 and six masters as air admission hole
