Description

A kind of vebrato chamber

Technical field

The utility model relates to a kind of vebrato chamber, mainly is applicable in the mobile phone.

Background technology

Conventional mobile phone vebrato chamber is earlier the vibrating loudspeakers monomer to be made, and then the monomer horn of the finished product sound chamber loam cake of packing into, welds lead-in wire, and the lower cover that closes is finished the assembling in sound chamber, and technology is more loaded down with trivial details, and acoustical quality is general, the cost height.

Summary of the invention

Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of reasonable in design is provided, and the vebrato chamber of excellent tonequality can be raised the efficiency and discharge to concise production process.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of vebrato chamber, comprise sound chamber loam cake, sound chamber lower cover, shell fragment, voice coil loudspeaker voice coil, vibrating diaphragm, quality loop, magnetic cover magnet steel, the pole piece sheet, terminal block and rubber-insulated wire, it is characterized in that: the pole piece sheet is connected with magnet steel, magnet steel is connected with the magnetic cover, magnetic cover and quality loop, shell fragment all connects, terminal block is connected with sound chamber loam cake, shell fragment is connected with sound chamber loam cake, voice coil loudspeaker voice coil is connected with vibrating diaphragm, the voice coil loudspeaker voice coil magnetic cover of packing into, magnet steel, between the pole piece sheet, vibrating diaphragm is connected with sound chamber loam cake, rubber-insulated wire and the welding of fishplate bar plate, and sound chamber loam cake is connected with sound chamber lower cover.

The utility model shell fragment and sound chamber loam cake link into an integrated entity.

Voice coil loudspeaker voice coil described in the utility model is resistant to elevated temperatures paper tube voice coil loudspeaker voice coil.

Vibrating diaphragm described in the utility model is a PU limit composite diaphragm.

The utility model compared with prior art has the following advantages and effect: 1. of the present utility model simple for structure, simplified the production stage of product, and improved production efficiency; 2. vibrating diaphragm of the present utility model is a PU limit composite diaphragm, can realize sound cavity Fo at 600Hz, and common pen film, the nearly approximate 1KHz of its F0, so the utility model acoustical quality is wanted a high last class; 3. adopt the paper tube voice coil loudspeaker voice coil, improved the power that bears in vebrato chamber, common its power of vebrato chamber is at 0.8W, and the utility model can reach the power of 2W.

The utility model has both vibration and two kinds of functions of voice, as be applied to field of mobile phones, promptly can replace vibrating motor to realize vibrating function again as electro-acoustic element, its operation principle is: utilize magnetic field and the coil that has alternating signal, make cutting magnetic line movement, realize that electric energy to magnetic energy and mechanical conversion of energy, causes the vibration of vibrating diaphragm, convert acoustic energy to.; On the other hand, the magnetic circuit of vibrating speaker partly is movable, and its important components is the vibration shell fragment, and shell fragment drives the vibration of magnetic cover under the reaction force of magnetosonic, thereby uses the vibration of whole sound chamber, has realized that electric energy is to mechanical transformation of energy.

The utility model is simple in structure, very easily produces in batches.
