Abstract
The utility model relates to an ultrathin receiver which comprises a support, a magnetic cover, magnetic steel, a pole chip, a voice coil, a diaphragm and a front cover. The voice coil is bound and fixed with the diaphragm, the voice coil is sleeved on the pole chip, the pole chip, the magnetic steel and the magnetic cover are successively bound and fixed, the edge of the diaphragm is bound and fixed with the support, the magnetic cover and the support are fixedly mounted, and the front cover is arranged over the diaphragm and fixed with the support. According to the utility model, the thickness of a prior receiver is decreased to the largest extent, so that the ultrathin receiver can be more suitable for mobile phones with narrow frames or even without frames; and on the basis that the thickness is reduced, a runway type magnetic circuit is employed, so that the sound quality is improved to some extent compared with the prior art.
Description
Technical field
The utility model relates to a kind of ultrathin receiver
,the electroacoustic component that belongs to communication, information system.
Background technology
Receiver is widely used on the meanss of communication such as mobile phone, microminiaturization along with electronic device, receiver is assembled on mobile phone as components and parts independently, receiver in the market, after reduction processing, the tonequality performance weakens, the utility model is the requirement to the sound index of terminal according to mobile phone production firm, two channel sound outputs have been designed, rationally determine its acoustic load impedance, the comprehensive quality of sound is effectively improved, comprise the subjective and objective index such as power output, richness, the distortion factor of loud speaker.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, to greatest extent the thickness of existing receiver has been carried out to attenuate, and has not affected the ultrathin receiver of its performance.
The technical scheme in the invention for solving the above technical problem is: this ultrathin type receiver, comprise support, magnetic cover, magnet steel, pole piece sheet, voice coil loudspeaker voice coil, vibrating diaphragm, protecgulum, described voice coil loudspeaker voice coil and vibrating diaphragm are adhesively fixed, and voice coil loudspeaker voice coil is placed in outside the pole piece sheet, pole piece sheet, magnet steel, magnetic cover are adhesively fixed successively, vibrating diaphragm edge and support are adhesively fixed, magnetic cover and support fixed installation, and the front vibrating diaphragm top that is covered on fixedly mounts with support.
The outline of voice coil loudspeaker voice coil described in the utility model, vibrating diaphragm is stadium of track and field runway shape.
Support integrated injection molding described in the utility model forms.
The utility model compared with prior art, have the following advantages and effect: the utility model has carried out attenuate to the thickness of existing receiver to greatest extent, more be applicable to as narrow frame or close to the structure of the mobile phone of " Rimless ", thereby on the basis of reduced thickness, adopt track and field racetrack magnetic circuit compared with prior art to have a certain upgrade on performance tonequality.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is plan structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail.
Embodiment:
Referring to Fig. 1 to Fig. 2, ultrathin receiver described in the utility model, comprise support 1, magnetic cover 2, magnet steel 3, pole piece sheet 5, voice coil loudspeaker voice coil 6, vibrating diaphragm 7, protecgulum 4, described voice coil loudspeaker voice coil 6 is adhesively fixed with vibrating diaphragm 7, and voice coil loudspeaker voice coil 6 is placed in outside pole piece sheet 5, between voice coil loudspeaker voice coil 6 and pole piece sheet 5, leaves space, pole piece sheet 5, magnet steel 3, magnetic cover 2 are adhesively fixed successively, the edge of vibrating diaphragm 7 and support 1 are adhesively fixed, magnetic cover 2 and support 1 fixed installation, and protecgulum 4 is located at vibrating diaphragm 7 tops and support 1 fixed installation.
The outline of voice coil loudspeaker voice coil 6 described in the utility model, vibrating diaphragm 7 is stadium of track and field runway shape, between two semicircles, is rectangle.
Support integrated injection molding described in the utility model forms.
The utility model outline is stadium of track and field runway shape, has increased magnetic circuit, thereby can promote the performance of receiver, meets the requirement of consumer to mobile phone tonequality.
