Therefore, be necessary to design and a kind ofly bear the comparatively large and panel speaker that volume is little of power.
Utility model content
For the above-mentioned problems in the prior art, the purpose of this utility model is to provide a kind of super-thin high power loud speaker, and it can bear relatively high power and highly sensitive.
To achieve these goals, the technical scheme that adopts of the utility model is as follows:
A kind of super-thin high power loud speaker, comprise frame, vibrating diaphragm, voice coil loudspeaker voice coil and magnetic circuit assembly, described magnetic circuit assembly comprises washer, magnet and U iron, described vibrating diaphragm comprises rectangular trunk and around the outstanding limit being arranged on described trunk outer rim, the shape of described voice coil loudspeaker voice coil is identical with the shape of described vibrating diaphragm, the shape of described washer and described magnet all with the mating shapes of described voice coil loudspeaker voice coil, the area of described voice coil loudspeaker voice coil accounts for more than 40% of described vibrating diaphragm area, described frame comprises the body of rectangle, be located in described body one end face for settling the step trough of described vibrating diaphragm and being located at the block for spacing described U iron on described body other end, the through hole for installing described voice coil loudspeaker voice coil and described magnetic circuit assembly is had in described step trough.
Compared to prior art, the beneficial effect of the utility model super-thin high power loud speaker is:
The thicker wire of wire diameter is coordinated to promote vibrating diaphragm by arranging the larger rectangular voice coil loudspeaker voice coil of caliber size and magnetic circuit assembly, more powerful than bearing of conventional speakers; Height after assembling only has 3mm, and adopts rectangular vibrating diaphragm to be more suitable for space narrow in ultra-thin panel computer, and improves the vibration area of vibrating diaphragm, the energy of efficiency utilization voice coil loudspeaker voice coil; Its structure is simple, easy to assembly, it is large and highly sensitive to bear power.
