Abstract
The invention provides a kind of acoustical generator, it comprises the voice coil loudspeaker voice coil being provided with voice coil leads, the vibrating diaphragm be connected with voice coil loudspeaker voice coil, and the wiring board to be electrically connected with voice coil loudspeaker voice coil, the ring portion that described vibrating diaphragm comprises ball top and extends along described ball top peripheral, described wiring board is provided with lug, and described lug is provided with the pad of welding voice coil leads, and described vibrating diaphragm is provided with the breach for place lug corresponding with lug.When acoustical generator of the present invention can reduce loudspeaker vibration, vibrating diaphragm encounters wiring board and the noise sent.
Description
[technical field]
The present invention relates to a kind of acoustical generator, particularly relate to a kind of diaphragm structure of acoustical generator.
[background technology]
Along with the development of science and technology, the technology content of acoustical generator design itself and the requirement of user more and more higher, especially require more and more higher to the sound performance of acoustical generator.
The acoustical generator of correlation technique, comprise the voice coil loudspeaker voice coil being provided with voice coil leads, the vibrating diaphragm be connected with voice coil loudspeaker voice coil, and the wiring board to be electrically connected with voice coil loudspeaker voice coil, described wiring board is provided with pad, and described voice coil leads is welded on pad, dodge accordingly owing to not doing at ball top, pad place, so just cause wiring board will give prominence to ball top a lot, make the ring portion of acoustical generator vibrating diaphragm when vibrating encounter wiring board, thus produce noise.
Therefore, be necessary to provide a kind of new acoustical generator.
[summary of the invention]
The object of the invention is that the acoustical generator solving said structure is encountered flexible circuit board due to vibrating diaphragm during vibration and produces the deficiency of noise or different sound, and provides a kind of acoustical generator that can reduce noise.。
The present invention is achieved by the following technical solutions:
A kind of acoustical generator, it comprises the voice coil loudspeaker voice coil being provided with voice coil leads, the vibrating diaphragm be connected with voice coil loudspeaker voice coil, and the wiring board to be electrically connected with voice coil loudspeaker voice coil, the ring portion that described vibrating diaphragm comprises ball top and extends along described ball top peripheral, described wiring board is provided with lug, and described lug is provided with the pad of welding voice coil leads, and described vibrating diaphragm is provided with the breach for place lug corresponding with lug.
Preferably, described wiring board is flexible circuit board.
Preferably, described lug is positioned at breach completely.
Preferably, described breach is two, and lug is corresponding two.
Preferably, described breach is arranged on the periphery at ball top.
Preferably, described breach is arranged on the periphery in ring portion.
Beneficial effect of the present invention is: because vibrating diaphragm is provided with the breach for place lug corresponding with lug, and such acoustical generator vibrating diaphragm when vibrating is just less encounters wiring board, thus reduces noise.
[accompanying drawing explanation]
Fig. 1 is acoustical generator one embodiment three-dimensional exploded view of the present invention.
[embodiment]
Below in conjunction with drawings and embodiments, for loud speaker, the invention will be further described.
Required by Fig. 1, be loud speaker one embodiment three-dimensional exploded view of the present invention, this loud speaker involving vibrations system 10, wiring board 20, magnetic circuit system 30 and the framework 40 for accommodating vibrational system 10, wiring board 20 and magnetic circuit system 30.
The vibrating diaphragm 11 that described vibrational system 10 comprises voice coil loudspeaker voice coil 12 and is connected with voice coil loudspeaker voice coil 12, described voice coil loudspeaker voice coil 12 is annuluses, and it correspondingly can produce magnetic field after powered up, and described voice coil loudspeaker voice coil 12 comprises a pair voice coil leads 121; The ring portion 111 that described vibrating diaphragm 11 comprises ball top 112 and extends along described ball top peripheral.
Described wiring board 20 stacks setting with vibrating diaphragm 11, and be interconnected, described wiring board 20 is provided with circumferential body portion 23, the conducting terminal 22 be connected with the external circuit board 50 and connects the connecting portion 24 of conducting terminal 22 and main part 23, wiring board 20 is provided with the lug 21 that main body 23 extends outward, described lug 21 is provided with pad (not shown), described voice coil leads 121 is welded on pad, and thus, wiring board 20 realizes being electrically connected with voice coil loudspeaker voice coil 12.
Described magnetic circuit system 30 comprises the first pole piece 31, magnet 32, second pole piece 33 and magnetic bowl 34.Described magnetic bowl 34 surrounds an ostiolate receiving space, described first pole piece 31, magnet 32 and the superimposed placement of the second pole piece 33, and correspondence is contained in the receiving space of described magnetic bowl 34.
In loud speaker of the present invention, described wiring board 20 is flexible circuit board, and described vibrating diaphragm 11 is provided with the breach 1121 corresponding with lug 21, and preferably, described breach 1121 is arranged on the periphery at ball top 112.Described breach is for placing lug 21, lug 21 also can be positioned at breach 1121 completely, thus, lug 21 gives prominence to the part minimizing at ball top 112, when voice coil loudspeaker voice coil 12 passes into alternating current, voice coil loudspeaker voice coil 12 can because the effect in magnetic field produces motion, along with the change of the sense of current, this motion also can change thereupon, thus drives vibrating diaphragm 11 to move up and down, just lessly when ring portion 111 moves up and down encounter wiring board 20, thus reach the object reducing noise.Certainly, described breach 1121 also can be located at the periphery in ring portion 111.
In the present embodiment, voice coil loudspeaker voice coil is provided with a pair voice coil leads, so described breach is two, lug is corresponding two, can certainly be other number.
In the embodiment of the loud speaker of foregoing invention, loud speaker is two magnetic route structure, namely comprises two voice coil loudspeaker voice coils, two magnetic circuit systems, and certainly in other embodiments, loud speaker also can be single magnetic structure or multipath magnetic circuit structure.
Above-described is only embodiments of the present invention, it should be pointed out that for the person of ordinary skill of the art at this, without departing from the concept of the premise of the invention, can also make improvement, but these all belongs to protection scope of the present invention.
