Abstract

The utility model relates to a large voice coil loudspeaker which is equipped with a transparent vibration diaphragm, including the vibration diaphragm, a corrugated rim, a voice coil and a magnetic circuit system. The voice coil is fixed on the periphery part of the vibration diaphragm which is made of transparent material. And the vibration diaphragm is not connected with other parts except the periphery part of the voice coil. The large voice coil loudspeaker of the utility model effectively solves the problem that the acoustics of a present loudspeaker is generally influenced by the segmentation vibration and the anti-vibration of a side ring, and improves the efficiency and the power of the loudspeaker. Furthermore, the loudspeaker adopts the transparent diaphragm which ensures the appearance of the large voice coil loudspeaker to be look like that the loudspeaker is only equipped with a narrow ring-shaped side frame, thus fully representing the unique working mode of the large voice coil loudspeaker of the vibration diaphragm periphery driving type, improves the enjoyment and the novelty of the loudspeaker, and enlarges the application range of the loudspeaker.

Description

The big voice-coil speaker of the transparent vibrating diaphragm of tool
Technical field
The utility model relates to loud speaker, is specifically related to a kind of big voice-coil speaker.
Background technology
Existing traditional cone woofer and some New-type loudspeakers such as panel speaker etc. all are that the center by vibrating diaphragm is connected voice coil loudspeaker voice coil, the diameter of voice coil loudspeaker voice coil is less than diaphragm diameter, this version of doing the single-piece piston vibration from the centre-driven vibrating diaphragm, owing to be subjected to factor affecting such as vibrating diaphragm rigidity and oscillating mass contradict, vibrating diaphragm can produce when making piston vibration in various degree harmful cuts apart vibration and side ring is counter shakes, and is difficult to make loud speaker tonequality and performance to reach comparatively ideal effect.In addition, the inherent structure of tradition cone woofer makes the centring disk of its compliance and stroke and loud speaker that bigger relation be arranged, because the diameter and the elasticity of centring disk are limited, and strengthen voice coil diameter the movable scope of centring disk will be reduced, thereby cause loud speaker compliance and stroke to reduce, because the relative vibrating diaphragm of voice coil loudspeaker voice coil can not major diameter design, improve thereby also limited performances such as loudspeaker enclosure, power widely.
In addition, the vibrating diaphragm of existing loud speaker generally adopts non-transparent material to make, and is also not enough to some extent aspect sight and novelty, limited further application.
Summary of the invention
The purpose of this utility model is the problems referred to above at existing loud speaker existence, provide a kind of and can eliminate effectively that side ring is counter to shake, cut apart vibration, reduce distortion rate, can improve electro-acoustic conversion efficiency and function, can enlarge the big voice-coil speaker of the transparent vibrating diaphragm of tool of loudspeaker applications.
The purpose of this utility model is achieved in that the utility model comprises vibrating diaphragm, ring, voice coil loudspeaker voice coil and magnetic circuit system, described voice coil loudspeaker voice coil is fixedly connected on the peripheral part of vibrating diaphragm, described vibrating diaphragm is made by transparent material, and vibrating diaphragm does not link to each other with other parts except that peripheral part.
Described voice coil loudspeaker voice coil is fixed on the junction part of the periphery and the ring of vibrating diaphragm.More firmly bonding like this.
Technique effect of the present utility model is:
1, the utility model is because voice coil loudspeaker voice coil is connected the periphery of vibrating diaphragm, formation is by the structure of peripheral drive vibrating diaphragm vibration, and this structure has been eliminated existing loud speaker effectively and shaken to the influence of tonequality because of the stiff problem of vibrating diaphragm causes the radial deformation vibration to cause that side ring is counter from the centre-driven vibrating diaphragm.
2, the utility model can be stablized more, effectively vibrating diaphragm be controlled owing to adopt the major diameter voice coil loudspeaker voice coil, makes it be difficult for deforming when seesawing, thereby reduces distortion rate.
3, this peripheral drive structure of the utility model has strengthened the diameter of voice coil loudspeaker voice coil, can improve the efficient and the power of loud speaker.
4, vibrating diaphragm of the present utility model does not link to each other with miscellaneous part except that the edge part, and vibrating diaphragm adopts transparent material to make, make loud speaker from seeming in appearance except transparent vibrating diaphragm, has only a narrow annular peripheral frame, this and conventional loudspeakers all are very different by the working method and the structure of centre-driven, therefore can demonstrate fully the work characteristics of this loud speaker; In addition,, improved the sight and the novelty of loud speaker, enlarged the range of application of loud speaker because vibrating diaphragm has adopted transparent material to make.
Description of drawings
Fig. 1 is the Facad structure figure of the utility model one embodiment.
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
Referring to Fig. 1 and Fig. 2, present embodiment comprises ring 1, vibrating diaphragm 2, voice coil loudspeaker voice coil 3, magnetic circuit system and frame, frame is combined by upper side frame 501 and lower frame 502, the edge of vibrating diaphragm 2 is fixed on the upper side frame 5 by ring 1, the shape of vibrating diaphragm 2 and voice coil loudspeaker voice coil 3 is supporting, be circle, the diameter of voice coil loudspeaker voice coil 3 is slightly less than the diameter of vibrating diaphragm 2, voice coil loudspeaker voice coil 3 is fixed on the junction part of the periphery and the ring 1 of vibrating diaphragm 2, magnetic circuit system adopts external magnetic type, by upper magnetic steel 401, magnet steel clamping plate 402 and lower magnetic steel 403 are formed, and its structure is existing mature technology, do not describe in detail at this, magnetic circuit system is installed in the frame, and voice coil loudspeaker voice coil 2 is suspended from the magnetic loop of magnetic circuit system, and vibrating diaphragm 2 is made by the transparent polyvinyl chloride material, and vibrating diaphragm 2 does not link to each other with other parts except that peripheral part, and this has constituted the big voice-coil speaker with transparent vibrating diaphragm like this.
Vibrating diaphragm in the utility model also can select for use polymethyl methacrylate, transparent propene nitrile-butadiene-styrene copolymer compound (being transparent ABS) or clear polycarbonate transparent materials such as (being transparent PC) to make.
The shape of vibrating diaphragm and voice coil loudspeaker voice coil is supporting in the utility model, they can be made into shapes such as circle, ellipse, rectangle, square, polygon or triangle, the size of voice coil loudspeaker voice coil is identical with the big I of vibrating diaphragm, also can be smaller so that both connections are more firm and be convenient to batch process.
Vibrating diaphragm is plane or the curved surface that certain radian is arranged in the utility model.
Magnetic circuit system in the utility model also can adopt existing ripe internal magnetization magnetic circuit system.
