Abstract

The utility model relates to a vibrating diaphragm periphery promoting loudspeaker. The loudspeaker takes use of the piston vibration of a vibrating diaphragm in the periphery driving form of the vibrating diaphragm, thereby effectively solving the problem that the acoustics of a traditional loudspeaker is commonly affected by the segmentation vibration and the reverse vibration of a side ring and improving the efficiency and the power of the loudspeaker.

Description

A kind of vibrating diaphragm periphery repulsive-type maglev panel speaker
Technical field
The utility model relates to a kind of vibrating diaphragm periphery repulsive-type maglev panel speaker.
Background technology
Existing panel speaker and traditional cone bass unit all are that the center by vibrating diaphragm is connected voice coil loudspeaker voice coil, its voice coil diameter is much smaller 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, vibrating diaphragm can produce when making piston vibration harmful cuts apart vibration and side ring is counter shakes, be difficult to make loud speaker tonequality and performance to reach comparatively ideal effect, simultaneously also because of being subjected to the loud speaker compliance, the restriction voice coil loudspeaker voice coil of diaphragm diameter is difficult to the major diameter design, thereby also limited current loudspeaker enclosure widely, performances such as power improve, this this problem performance more outstanding in the thin flat loud speaker, and in frequency response, be easy to produce big peak or large space between muscles makes frequency response curve not straight.
Summary of the invention
The purpose of this utility model provides a kind ofly can effectively eliminate the anti-driving high-performance loadspeaker structure in vibrating diaphragm edge that shakes, cuts apart vibration, can improve electro-acoustic conversion efficiency and power of side ring.
Embodiment of the present utility model is: the utility model comprises voice coil loudspeaker voice coil, vibrating diaphragm, ring, magnetic circuit, bullet ripple, and described voice coil loudspeaker voice coil is fastened on the periphery of vibrating diaphragm.
The utility model is because voice coil loudspeaker voice coil is connected the periphery of vibrating diaphragm, formation is made the piston vibration structure by the peripheral drive vibrating diaphragm, this structure has been eliminated current loud speaker effectively and has been 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, strengthen the diameter of voice coil loudspeaker voice coil in addition again because of this drive form, therefrom also can improve the efficient and the power of loud speaker.
Description of drawings
Fig. 1 is an external magnetic circuit structural representation of the present utility model; Fig. 2 is an internal magnetic circuit structural representation of the present utility model; Fig. 3 is the high-power bass unit structural representation of the utility model.
With reference to Fig. 1, this vibrating diaphragm peripheral drive type loudspeaker by 1, ring 2, vibrating diaphragm 3, voice coil loudspeaker voice coil 4, outer Magnetic circuit system forms.
With reference to Fig. 2, this peripheral drive type loudspeaker internal magnetization by 1, ring, 2, vibrating diaphragm 3, voice coil loudspeaker voice coil 4, in Magnetic circuit system forms.
With reference to Fig. 3, the high-power woofer of this peripheral drive type by: 1, ring, 2, the prominent solid of the back of the body are flat Face vibrating diaphragm, 3, voice coil loudspeaker voice coil 4, magnetic circuit system 5, bullet wave component.
Embodiment
In the embodiment shown in fig. 1, the diameter of voice coil loudspeaker voice coil 3 diameter by vibrating diaphragm 2 is designed and produced, magnetic circuit becomes external magnetic circuit system 4 by voice coil loudspeaker voice coil 3 size design, with voice coil loudspeaker voice coil 3 routinely loud speaker assembling technology be fixed on the periphery of vibrating diaphragm 2, be assembled into external magnetic type vibrating diaphragm periphery repulsive-type maglev panel speaker.
In the embodiment shown in Figure 2, magnetic circuit becomes internal magnetic circuit system 4 by voice coil loudspeaker voice coil 3 size design, and all the other are assembled into internal magnetization vibrating diaphragm periphery repulsive-type maglev panel speaker with embodiment illustrated in fig. 1.
In another embodiment shown in Figure 3, the diameter of voice coil loudspeaker voice coil 3 is made by the size design of the prominent solid plane diaphragm 2 of the back of the body, magnetic circuit system 4 becomes external magnetic type by voice coil loudspeaker voice coil 3 size design, also can adopt the internal magnetization design, with voice coil loudspeaker voice coil 3 routinely loud speaker assembling technology be fixed on the periphery of the prominent solid plane diaphragm 2 of the back of the body, be assembled into high-power bass vibrating diaphragm periphery repulsive-type maglev panel speaker.
In the implementation procedure of the present utility model, also can as required voice coil diameter be designed to be slightly less than the diameter of vibrating diaphragm for fastness and the batch process that connects.
