Abstract
The invention provides an acoustic generator which comprises a magnetic frame and a hearing aid voice coil, wherein the magnetic frame is provided with a side wall and a lower bottom surface connected with the side wall; and the hearing aid voice coil is sleeved on the side wall. The acoustic generator can greatly improve the induced magnetic field of the hearing aid voice coil so as to improve the integral hearing aid function of the acoustic generator.
Description
[technical field]
The present invention designs acoustical generator field, particularly relates to the acoustical generator that a kind of antijamming capability is strong.
[background technology]
Along with the development of electronic technology, electronic communication equipment is gradually to future developments such as frivolous, high tone qualities.Therefore, how under the prerequisite ensureing production reliability, to realize electronic communication equipment thin design, there is again high tone quality performance and just become industry to compare the problem of concern.
The acoustical generator of correlation technique, comprise the magnet frame of protecgulum, voice coil loudspeaker voice coil and collecting voice coil loudspeaker voice coil, the acoustical generator of this structure, a listening help circle is added under the protecgulum of acoustical generator or in the bottom of magnet frame, its problem is: add a listening help circle when acoustical generator is height-limited and can take a lot of oscillation space, the induced field of its listening help circle also can not be too strong simultaneously, and antijamming capability is more weak.
Therefore be necessary to provide a kind of novel acoustical generator in fact.
[summary of the invention]
The technical problem that the present invention need solve is to provide the strong acoustical generator of a kind of antijamming capability.
For solving the problems of the technologies described above, the invention provides a kind of acoustical generator, it comprises magnet frame, the bottom surface that described magnet frame is provided with sidewall and is connected with sidewall, and comprise listening help circle further, described listening help circle is sheathed on described sidewall.
Preferably, described sidewall is divided into disjunct four parts mutually, at sheathed two listening help circles of the non-conterminous two parts of described sidewall.
Preferably, the angle that described sidewall and described bottom surface are formed is 0 ° ~ 180 °.
Preferably, the angle that described sidewall and bottom surface are formed is 45 °.
The beneficial effects of the utility model are: take full advantage of magnet frame in magnetic structure as the iron core in coil, significantly strengthen the magnetic field of listening help circle, thus improve the hearing-aid function of acoustical generator entirety, the height of acoustical generator can not be taken again simultaneously, larger oscillation space can be provided for vibrational system.
[accompanying drawing explanation]
Fig. 1 is acoustical generator one embodiment perspective exploded view of the present invention;
Fig. 2 is acoustical generator one embodiment magnetic circuit system schematic diagram of the present invention.
[embodiment]
Below in conjunction with drawings and embodiments, the invention will be further described.
As shown in Figure 1, for acoustical generator one embodiment perspective exploded view of the present invention, the acoustical generator of this structure, involving vibrations system (sign), the auxiliary system (sign) of magnetic circuit system (sign) and collecting vibrational system and magnetic circuit system, described vibrational system comprises vibrating diaphragm 1, described magnetic circuit system comprises pole piece 2, the magnet frame 4 of voice coil loudspeaker voice coil 3 and collecting voice coil loudspeaker voice coil 3, described auxiliary system comprises protecgulum 5 and frame 6, described magnet frame 4 is contained in frame 6, described magnet frame 4 is provided with sidewall (sign), described sidewall is divided into disjunct four parts mutually, at the non-conterminous two parts of described sidewall sheathed first listening help circle 7 and the second listening help circle 8 respectively, described magnet frame 4 is provided with bottom surface 41, and the angle that described first listening help circle 7 and the second listening help circle 8 and described bottom surface 41 are formed is 45 °.
As shown in Figure 2, be one embodiment of the invention magnetic circuit system schematic diagram, described magnetic circuit system comprises the magnet frame 4 of magnet (not shown), pole piece 2, voice coil loudspeaker voice coil 3 and collecting voice coil loudspeaker voice coil 3, the superimposed setting successively of described pole piece 2, magnet and described magnet frame 4; Described voice coil loudspeaker voice coil 3 is annuluses, it is wound around to arrange by multiturn metal wire and is formed, as: copper conductor etc., described voice coil loudspeaker voice coil 3 correspondingly can produce magnetic field after powered up, described magnet frame 4 is provided with bottom surface 41, and preferred as in the present embodiment, the angle of described sidewall and described bottom surface 41 is 45 °, certainly, the angle of described sidewall and described bottom surface 41 can be the arbitrary value of 0 ° ~ 180 ° of centres.
The acoustical generator of structure of the present invention, take full advantage of magnet frame 4 in magnetic circuit system as the iron core in coil, significantly strengthen the magnetic field of listening help circle, thus improve the hearing-aid function of acoustical generator entirety, the height of acoustical generator can not be taken again simultaneously, larger oscillation space can be provided for vibrational system.
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.
