Description
[technical field]
The present invention relates to a kind of mini-sound device, especially relate to a kind of minitype acoustic generator that has hearing-aid function.
[background technology]
In recent years along with the fast development of mobile communication technology, the consumer uses mobile communication equipment more and more, and for example portable phone, the portable phone that can surf the Net, personal digital assistant, laptop computer, laptop computer, figure input card maybe can be by other equipment public or that dedicated communications network communicates.The growing demand of the said equipment has promoted the improvement of manufacturing process, power consumption and the miniaturization aspect of integrated audio components thereon.
Please join shown in Figure 1, the mini-sound device 1 of dependency structure ', it comprise basin frame 11 ', be contained in the magnetic bowl 12 of basin frame 11 ' interior ', be placed in the permanent magnet 13 of magnetic bowl 12 ' interior ', be arranged on permanent magnet 13 ' and magnetic bowl 12 ' between voice coil loudspeaker voice coil 14 ', with the vibrating diaphragm 15 of voice coil loudspeaker voice coil 14 ' be connected ', lid be connected to basin frame 11 ' on lid 16 ' and fit in lid 16 ' on hearing aid coil 17 '.Listening help circle 17 ' be the service function that provides for the dysaudia personage, utilize the alternating electromagnetic field and the induction of the hearing aids in Hearing Impaired's ear of listening help circle 17 ' generation, can help the Hearing Impaired to hear sound.
Wherein, the insulating barrier (not shown) of listening help circle 17 ' be located at the sheet metal periphery by continuous sheet metal (not shown) and bag is entwined.Listening help circle 17 ' the volume that utilizes canoe to make is bigger, if with its be fixed in lid 16 ' on, certainly will take mini-sound device 1 ' volume inside, cause mini-sound device 1 ' volume very big, can't adapt to the direction of miniaturization development.
Therefore, be necessary the minitype acoustic generator of dependency structure is improved.
[summary of the invention]
The technical problem that the present invention need solve provides the minitype acoustic generator that a kind of volume is little, hearing-aid function is good.
According to the above-mentioned technical problem that needs solution; the present invention has designed a kind of minitype acoustic generator; involving vibrations system, magnetic circuit system, protecgulum, basin frame; vibrational system and magnetic circuit system are contained in the basin frame; protecgulum comprises upper surface and lower surface; the lower surface of protecgulum links to each other with the basin frame; on the upper surface of protecgulum or lower surface, be provided with the hearing aid element of ring-type, described hearing aid element comprise first protective layer, second insulating barrier and be sandwiched in first protective layer and second insulating barrier between thin, surperficial spiral coating coil.
The present invention also provides the manufacture method of this hearing aid element, comprising:
(1), first protective layer of ring-type is provided;
(2), on first protective layer, adopt the way of sputter or evaporation to plate the thin copper of one deck;
(3), then the principle that adopts photoetching to take a picture erodes the copper of not wanting after developing with chemical reagent, obtain spiral helicine coating coil;
(4), on the coating coil, coat second insulating barrier again.
Further improve as the present invention, first protective layer, second insulating barrier are made by protection glue or silica gel.
Coating voice coil loudspeaker voice coil of the present invention erodes material not by a thin copper sheet by chemical reagent, obtains spiral helicine coil, and its function is equivalent to the spiral coil that very thin copper cash in one plane is entwined.This coating coil also can produce alternating electromagnetic field after energising, reach the function of hearing aid.More excellent is, coating voice coil loudspeaker voice coil of the present invention can be made very thinly, and whole hearing aid element has thin advantage, and compared with prior art, hearing aid component size of the present invention is little, does not take up space, and helps the microminiaturization of product.

Fig. 1 is the cross-sectional schematic of prior art minitype acoustic generator;
Fig. 2 is the cross-sectional schematic of minitype acoustic generator of the present invention;
Fig. 3 is the enlarged drawing at A place among Fig. 2;
Fig. 4 is the exploded perspective view of hearing aid element of the present invention.
[embodiment]
The invention will be further described below in conjunction with drawings and embodiments.
As Fig. 2, shown in Figure 3, be minitype acoustic generator 1 of the present invention, involving vibrations system, magnetic circuit system, protecgulum 16, basin frame 11.
Vibrational system comprises voice coil loudspeaker voice coil 14 and vibrating diaphragm 15.Magnetic circuit system comprises magnet frame 12, permanent magnet 13 and pole piece 18.Magnet frame 12 is contained in the basin frame 11, and permanent magnet 13 and pole piece 18 are contained in the magnet frame and form magnetic gap, and voice coil loudspeaker voice coil links to each other with vibrating diaphragm and is suspended in the magnetic gap, and vibrating diaphragm 15 peripheries are fixed on the basin frame 11.Protecgulum comprises upper surface and lower surface, and lower surface closes on vibrating diaphragm, links to each other with the basin frame.Present embodiment is provided with hearing aid element 17 on the lower surface of protecgulum.As shown in Figure 4; this hearing aid element 17 comprises first protective layer 171, second insulating barrier 172 and coating coil 170; coating coil 170 is shape in the shape of a spiral, is sandwiched between first protective layer, second insulating barrier, and the function of first protective layer, second insulating barrier is the protective coating coil and is used for insulation.The present invention also is provided with the hearing aid element at the upper surface of protecgulum.The hearing aid element can be bonded on the upper surface or lower surface of protecgulum by the mode of glue gummed.
The manufacture method of this hearing aid element is:
