Abstract
The invention provides a sound generator, comprising a voice coil with voice coil leads, a diaphragm connected with the voice coil and a circuit board electrically connected with the voice coil, wherein the diaphragm comprises a spherical top and a corrugated rim part extending along the periphery of the spherical top; the circuit board is provided with lugs; the lugs are provided with pads for welding the voice coil leads; and the diaphragm is provided with nicks which correspond to the lugs and are used for placing the lugs. The sound generator can reduce the noises produced when the diaphragm touches the circuit board when the loudspeaker vibrates.
Description
[technical field]
The present invention relates to a kind of acoustical generator, relate in particular to a kind of diaphragm structure of acoustical generator.
[background technology]
Along with the continuous development of science and technology, the technology content of acoustical generator self design and user's requirement are more and more higher, and especially the sound performance to acoustical generator requires more and more higher.
The acoustical generator of correlation technique, comprise the voice coil loudspeaker voice coil that is provided with voice coil leads, the vibrating diaphragm that is connected with voice coil loudspeaker voice coil, and the wiring board that is electrically connected with voice coil loudspeaker voice coil, described wiring board is provided with pad, and described voice coil leads is welded on the pad, do not dodge owing to doing accordingly at ball top, pad place, it is a lot of so just to cause wiring board will give prominence to the ball top, makes the ring portion of acoustical generator vibrating diaphragm when vibration can run into wiring board, thereby produces noise.
Therefore, be necessary to provide a kind of new acoustical generator.
[summary of the invention]
The acoustical generator that the object of the invention is to solve said structure during owing to vibration vibrating diaphragm run into the deficiency that flexible circuit board produces noise or different sound, and provide 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 that is provided with voice coil leads, the vibrating diaphragm that is connected with voice coil loudspeaker voice coil, and the wiring board that is electrically connected with voice coil loudspeaker voice coil, described vibrating diaphragm comprises ball top and the ring portion of extending along described ball top periphery, 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 that lug is placed in be used to corresponding with lug.
Preferably, described wiring board is a flexible circuit board.
Preferably, described lug is positioned at breach fully.
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 of ring portion.
Beneficial effect of the present invention is: because vibrating diaphragm is provided with the breach that lug is placed in be used to corresponding with lug, acoustical generator vibrating diaphragm when vibration is run into wiring board with regard to less like this, thereby reduces noise.
[description of drawings]
Fig. 1 is acoustical generator one an embodiment three-dimensional exploded view of the present invention.
[embodiment]
Below in conjunction with drawings and embodiments is that the invention will be further described for example with the loud speaker.
Ask as 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 be used to accommodate the framework 40 of vibrational system 10, wiring board 20 and magnetic circuit system 30.
Described vibrational system 10 comprises voice coil loudspeaker voice coil 12 and the vibrating diaphragm 11 that is connected with voice coil loudspeaker voice coil 12, and described voice coil loudspeaker voice coil 12 is annuluses, and it can correspondingly produce magnetic field after energising, and described voice coil loudspeaker voice coil 12 comprises a pair of voice coil leads 121; Described vibrating diaphragm 11 comprises ball top 112 and the ring portion 111 of extending along described ball top periphery.
Described wiring board 20 stacks setting with vibrating diaphragm 11, and interconnects, and wiring board 20 is provided with lug 21, and described lug 21 is provided with pad (not shown), and described voice coil leads 121 is welded on the pad, and thus, wiring board 20 is realized being electrically connected with voice coil loudspeaker voice coil 12.Also be provided with conducting terminal 22 on the wiring board 20, conducting terminal 22 is electrically connected with the external circuit board 50.
Described magnetic circuit system 30 comprises 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 33 superimposed placements of second pole piece, and corresponding being contained in the receiving space of described magnetic bowl 34.
In loud speaker of the present invention, described wiring board 20 is a flexible circuit board, and described vibrating diaphragm 11 is provided with the breach 1121 corresponding with lug 21, and preferred, described breach 1121 is arranged on the periphery at ball top 112.Described breach is used to place lug 21, lug 21 also can be positioned at breach 1121 fully, thus, the part at lug 21 outstanding ball tops 112 reduces, when voice coil loudspeaker voice coil 12 feeds alternating current, voice coil loudspeaker voice coil 12 can be because the effect in magnetic field produces motion, along with the variation of the sense of current, this motion also can change thereupon, moves up and down thereby drive vibrating diaphragm 11, just lessly when ring portion 111 moves up and down run into wiring board 20, thereby reach the purpose that reduces noise.Certainly, described breach 1121 also can be located at the periphery of ring portion 111.
In the present embodiment, voice coil loudspeaker voice coil is provided with a pair of 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 a two magnetic route structure, promptly 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 only is embodiments of the present invention, should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the invention design, can also make improvement, but these all belongs to protection scope of the present invention.
