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 the acoustical generator field, relates in particular to the strong acoustical generator of a kind of antijamming capability.
[background technology]
Along with development of electronic technology, electronic communication equipment develops to directions such as frivolous, high tone qualities gradually.Therefore, how under the prerequisite that guarantees production reliability, to realize the electronic communication equipment thin design, have the problem that the high tone quality performance has just become industry relatively to pay close attention to again.
The acoustical generator of correlation technique, comprise protecgulum, voice coil loudspeaker voice coil and the magnet frame of accommodating voice coil loudspeaker voice coil, the acoustical generator of this structure, under the protecgulum of acoustical generator or in the bottom of magnet frame, add a listening help circle, its problem is: add a listening help circle and can take a lot of oscillation spaces under the height-limited situation of acoustical generator, simultaneously the induced field of its listening help circle can be too not strong yet, antijamming capability a little less than.
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 provides 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, and the bottom surface that described magnet frame is provided with sidewall and links to each other with sidewall further comprises listening help circle, and described listening help circle is sheathed on the 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 of described sidewall and described bottom surface formation is 0 °～180 °.
Preferably, the angle of described sidewall and bottom surface formation is 45 °.
The beneficial effects of the utility model are: made full use of the magnet frame in the magnetic structure as the iron core in the coil, significantly strengthen the magnetic field of listening help circle, thereby improve the hearing-aid function of acoustical generator integral body, can not take simultaneously the height of acoustical generator again, can provide bigger oscillation space for vibrational system.
[description of drawings]

Fig. 2 is acoustical generator one an embodiment magnetic circuit system schematic diagram of the present invention.
[embodiment]
The invention will be further described below in conjunction with drawings and embodiments.
As shown in Figure 1, be acoustical generator one embodiment perspective exploded view of the present invention, the acoustical generator of this structure, involving vibrations system (not indicating), magnetic circuit system (not indicating) and the auxiliary system (not indicating) of accommodating vibrational system and magnetic circuit system, described vibrational system comprises vibrating diaphragm 1, described magnetic circuit system comprises pole piece 2, voice coil loudspeaker voice coil 3 and the magnet frame 4 of accommodating voice coil loudspeaker voice coil 3, described auxiliary system comprises protecgulum 5 and basin frame 6, described magnet frame 4 is contained in the basin frame 6, described magnet frame 4 is provided with sidewall (not indicating), described sidewall is divided into disjunct four parts mutually, at non-conterminous two parts sheathed first listening help circle 7 of difference of described sidewall and second listening help circle 8; Described magnet frame 4 is provided with bottom surface 41, and described first listening help circle 7 and second listening help circle 8 are 45 ° with the angle that described bottom surface 41 forms.
As shown in Figure 2, be one embodiment of the invention magnetic circuit system schematic diagram, described magnetic circuit system comprises magnet (not shown), pole piece 2, voice coil loudspeaker voice coil 3 and the magnet frame 4 of accommodating voice coil loudspeaker voice coil 3, the superimposed successively setting of described pole piece 2, magnet and described magnet frame 4; Described voice coil loudspeaker voice coil 3 is annuluses, it is twined to be provided with by the multiturn metal wire and forms, as: copper conductor etc., described voice coil loudspeaker voice coil 3 can correspondingly produce magnetic field after energising, 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, make full use of the magnet frame 4 in the magnetic circuit system as the iron core in the coil, significantly strengthened the magnetic field of listening help circle, thereby improved the hearing-aid function of acoustical generator integral body, can not take simultaneously the height of acoustical generator again, can provide bigger oscillation space for vibrational system.
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.
