Abstract
The utility model discloses a kind of loudspeaker, comprise loudspeaker skeleton, annular magnet, magnetic core, voice coil loudspeaker voice coil and cone, in loudspeaker skeleton, bottom is provided with annular magnet, annular magnet centre position is provided with magnetic core, voice coil loudspeaker voice coil is placed in magnetic core by speech coil framework, speech coil framework is arranged in the gap between annular magnet and magnetic core, respectively there is a groove matched with binding post at described speech coil framework two ends, voice coil loudspeaker voice coil upper surface is provided with dust cover, its periphery, upper end is connected with elastic membrane, and described cone lower end is connected on speech coil framework.The utility model overcomes the deficiencies in the prior art, can simplify assembly technology, saves installation time, improves the fixed structure of the coil of assembly quality.
Description
Technical field
The utility model relates to small-bore loudspeaker technical field, specifically belongs to a kind of loudspeaker.
Background technology
Loudspeaker are loud speaker again, be a kind of very conventional electro-acoustic transducer device, divide moving-coil type (electrodynamic type), condenser type (electrostatic), piezoelectric type (crystal or pottery), electromagnetic type (compressed spring type), electric ion type and pneumatic type loudspeaker etc. by transducing mechanism and structure; The coil that existing loudspeaker use, normally first passes coil rack hole by lead-out wires of coil when assembling, then through printed board hole, is then welded in printed board by lead-out wires of coil end.The assembly method complex process of this lead-out wires of coil, time-consumingly takes a lot of work, and skeleton inner bottom part does not have reinforcement, and it is not very stable for making during mounting circuit boards.
Utility model content
For the problems referred to above, the purpose of this utility model there is provided a kind of loudspeaker, overcomes the deficiencies in the prior art, can simplify assembly technology, saves installation time, improves the fixed structure of the coil of assembly quality.
The technical solution adopted in the utility model is as follows:
A kind of loudspeaker, comprise loudspeaker skeleton, annular magnet, magnetic core, voice coil loudspeaker voice coil and cone, in described loudspeaker skeleton, bottom is provided with annular magnet, annular magnet centre position is provided with magnetic core, voice coil loudspeaker voice coil is placed in magnetic core by speech coil framework, speech coil framework is arranged in the gap between annular magnet and magnetic core, respectively there is a groove matched with binding post at described speech coil framework two ends, voice coil loudspeaker voice coil upper surface is provided with dust cover, its periphery, upper end is connected with elastic membrane, and described cone lower end is connected on speech coil framework.
The open side of described loudspeaker skeleton is also provided with a flanging.
The described loudspeaker skeleton back side is provided with wire joint pin.
The described loudspeaker back side is connected with loudspeaker and installs elastic supporting plate.
Elastomeric pad is provided with below described speech coil framework.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model, by voice coil loudspeaker voice coil lower end linking springs pad, makes voice coil loudspeaker voice coil and sound basin have good linear working characteristic, reduces the nonlinear distortion of sound basin motion, makes loudspeaker have the service behaviour of high efficiency, high-fidelity; Respectively design a groove at coil rack two ends, two binding posts on fixed printed board simultaneously, eliminate for two of threading apertures on original coil rack, improve installation effectiveness.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
