Abstract
The invention provides a loudspeaker, and is suitable for the technical field of microphones. The loudspeaker comprises a vibrating diaphragm and two strip-shaped voice coil units combined with the lower side of the vibrating diaphragm, wherein the voice coil units are arranged on the vibrating diaphragm in parallel; the vibrating diaphragm comprises a top part of a ball at the center of the vibrating diaphragm and a folding-ring part at the periphery of the vibrating diaphragm; the voice coil units are both combined with the top of the ball of the vibrating diaphragm; magnetic circuit mechanisms are correspondingly arranged on the voice coil units respectively; each magnetic circuit mechanism comprises a washer, a magnet and a basin stand, which are sequentially combined with the magnetic circuit mechanism and form a magnetic gap for accommodating the corresponding voice coil unit; and a shell used for accommodating and fixing the vibrating diaphragm, the voice coil units and the magnetic circuit mechanisms is adopted. The loudspeaker comprises the treble-bass shared vibrating diaphragm, the voice coil units and the magnetic circuit mechanism, and does not need to be designed separately, open a mold again and the like, thereby effectively reducing the production cost of a bass loudspeaker.
Description
Technical field
The present invention relates to the mike technique field, relate in particular to a kind of loud speaker.
Background technology
The consumer to the audio of electronic product require increasingly high, in order to obtain better tonequality, in loud speaker usually with the voice signal of high band and low-frequency range respectively by high pitch loudspeaker and woofer broadcast.
Woofer and high pitch loudspeaker have many differences in design, its best effort frequency range of the loud speaker that for example the vibrating diaphragm size is different with material is also different, and the loud speaker low frequency characteristic that bore is big more is also good more or the like.Therefore, the woofer in the existing design adopts different vibrational systems and magnetic circuit system respectively with high pitch loudspeaker usually, needs to be directed against a series of preparations such as woofer designs, die sinking tool separately, is unfavorable for the saving of cost.
Summary of the invention
The object of the present invention is to provide a kind of loud speaker, be intended to solve the prior art medium and low spectrum loudspeaker and adopt different vibrational systems and this road system, cost problem of higher respectively with high pitch loudspeaker.
The present invention is achieved in that a kind of loud speaker, and said loud speaker comprises:
A vibrating diaphragm;
Be incorporated into the voice coil unit of two strips of said vibrating diaphragm downside, said voice coil unit is set in parallel on the said vibrating diaphragm, and said vibrating diaphragm comprises the ring portion at the ball top and the edge at center, and said voice coil unit combines with the ball top of said vibrating diaphragm;
With the magnetic circuit mechanism of the corresponding setting of said voice coil unit, said magnetic circuit mechanism comprises the magnetic gap that corresponding voice coil unit is accommodated in the washer, magnet and the basin frame that combine successively and formation;
Accommodate the shell of fixing said vibrating diaphragm, voice coil unit and magnetic circuit mechanism.
As a kind of improvement, said voice coil unit comprises the speech coil framework of voice coil loudspeaker voice coil and fixing said voice coil loudspeaker voice coil, and said voice coil loudspeaker voice coil combines with said vibrating diaphragm through said speech coil framework.
Loud speaker provided by the invention comprises high pitch and shared vibrating diaphragm, voice coil unit and the magnetic circuit mechanism of bass, does not need to design separately, die sinking tool etc., has reduced the production cost of woofer effectively.
Description of drawings
Fig. 1 is the structural representation of loud speaker provided by the invention.
Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Fig. 1 shows the structural representation of loud speaker provided by the invention, for the ease of explanation, has only provided the part relevant with the present invention among the figure.
Loud speaker comprises vibrating diaphragm 1, voice coil unit 2 and magnetic circuit mechanism 3, and it is specially:
The protection structure of vibrating diaphragm 1 and shell formation woofer, vibrating diaphragm 1 comprises the ring portion at the ball top and the edge at center, wherein the ball top has certain rigidity.
Two voice coil units 2 are set in parallel on the vibrating diaphragm 1.
Magnetic circuit mechanism 3 and voice coil unit 2 corresponding settings.
Voice coil unit 2 and corresponding magnetic circuit mechanism 3 all adopt the parts in the high pitch loudspeaker; The design that this a plurality of high pitch loudspeaker voice coil unit 2 drives a woofer vibrating diaphragm 1 can be expanded frequency range effectively and realized bass effect; And these part parts do not need to design separately, die sinking tool etc., have reduced the production cost of woofer effectively.
In this embodiment, voice coil unit 2 is the strip structure, comprises the voice coil loudspeaker voice coil of strip and the fixing speech coil framework of voice coil loudspeaker voice coil, and voice coil loudspeaker voice coil combines with the ball top of vibrating diaphragm 1 through speech coil framework.Adopt strip voice coil loudspeaker voice coil structure, can increase bonded area with the ball top.
This loud speaker also is provided with the bullet ripple, and it is arranged between voice coil unit and the shell, and it is fixed in the bottom at voice coil unit 2 two ends, specifically is arranged at the two ends of speech coil framework bottom, can prevent in voice coil unit 2 vibration processes polarization to take place.The structure that this bullet ripple is arranged at the voice coil unit bottom can make full use of the space of inside loudspeakers, thereby can make product thinner.
In this embodiment, magnetic circuit mechanism 3 comprises washer, magnet and the basin frame that combines successively, and magnetic circuit mechanism 3 forms the magnetic gap of accommodating voice coil unit 2, and in this implementation process, magnetic circuit mechanism 3 comprises two independent parts, is convenient to simplify production technology.
Loud speaker provided by the invention comprises high pitch and shared vibrating diaphragm, voice coil unit and the magnetic circuit mechanism of bass, does not need to design separately, die sinking tool etc., has reduced the production cost of woofer effectively.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
