The content of the invention
The purpose of the present invention is to propose to the audio cavity structure that a kind of side simple in construction, more frivolous is spoken.
To reach above-mentioned purpose, the present invention proposes the audio cavity structure that a kind of side is spoken, including the bottom being mutually fastened Shell and top shell, circuit board and loudspeaker are built-in between the drain pan and top shell, the loudspeaker is electrically connected to circuit board, described Drain pan goes out acoustic aperture in the sidepiece close to loudspeaker provided with side, and the loudspeaker includes vibrating diaphragm, ring, voice coil loudspeaker voice coil 43, frame and magnet steel, The frame is on magnet steel, and the voice coil loudspeaker voice coil is sheathed in magnet steel, and the vibrating diaphragm and ring are sequentially arranged in frame, and described Vibrating diaphragm is spoken facing to magnet steel, and sound wave caused by the vibrating diaphragm goes out acoustic aperture via the sidepiece and side of magnet steel and sent.
Further, in the audio cavity structure that above-mentioned side is spoken, the drain pan be provided with the first cavity and with first chamber The second adjacent cavity of body phase, first cavity and the second cavity peripheral edge are provided with multiple fixed columns, the multiple fixed column Interior to be provided with mounting hole, the circuit board cover is fixed on one on the first cavity and the second cavity, and by fixture and drain pan Rise.
Further, in the audio cavity structure that above-mentioned side is spoken, first cavity and the second cavity are separated by dividing plate.
Further, in the audio cavity structure that above-mentioned side is spoken, the bottom of first cavity and the second cavity passes through a tunnel Road hole communicates.
Further, in the audio cavity structure that above-mentioned side is spoken, the loudspeaker is placed in the second cavity, described to raise one's voice The rear sound chamber of one sealing is formed on device, circuit board, dividing plate and the bottom of the first cavity and the second cavity.
Further, in the audio cavity structure that above-mentioned side is spoken, the vibrating diaphragm is spoken facing to magnet steel, the side of the magnet steel Portion goes out acoustic aperture towards side.
The audio cavity structure that side of the present invention is spoken is set by the way that the vibrating diaphragm of loudspeaker is spoken facing to magnet steel direction, with magnet steel Sidepiece as go out sound face, so as to reduce parts, simplify structure, reduce the thickness and weight of whole audio cavity structure, It is very beneficial for realizing the lightening requirement of product.
Brief description of the drawings
Fig. 1 is the structural representation for the audio cavity structure that prior art side is spoken;
Fig. 2 is the decomposition texture schematic diagram for the audio cavity structure that side of the present invention is spoken;
Fig. 3 is the diagrammatic cross-section for the audio cavity structure that side of the present invention is spoken;
Fig. 4 is another diagrammatic cross-section for the audio cavity structure that side of the present invention is spoken.
Embodiment
The preferred embodiment that the invention will now be described in detail with reference to the accompanying drawings.
Fig. 2, Fig. 3 and Fig. 4 are referred to, the audio cavity structure that side of the present invention is spoken includes the drain pan 1 being mutually fastened and top Shell 2, is built-in with circuit board 3 and loudspeaker 4 between the drain pan 1 and top shell 2, the loudspeaker 4 is electrically connected to circuit board 3, institute State drain pan 1 and be provided with side in the sidepiece close to loudspeaker 4 and go out acoustic aperture 12, the loudspeaker 4 including vibrating diaphragm 41, ring 42, voice coil loudspeaker voice coil 43, Frame 44 and magnet steel 45, on the magnet steel 45, the voice coil loudspeaker voice coil 43 is sheathed in magnet steel 45 frame 44, the vibrating diaphragm 41 and Ring 42 is sequentially arranged in frame 44, and the vibrating diaphragm 41 is spoken facing to magnet steel 46, and sound wave caused by the vibrating diaphragm 41 passes through Go out acoustic aperture 12 by the sidepiece and side of magnet steel 46 to send.
Wherein, the drain pan 1 is provided with the first cavity 14 and second cavity 16 adjacent with first cavity 14, described First cavity 14 and the peripheral edge of the second cavity 16 are provided with multiple fixed columns 15, and mounting hole is provided with the multiple fixed column 15 (Figure is not marked), the circuit board 3 is covered on the first cavity 14 and the second cavity 16, and is fixed by fixture 32 and drain pan 1 Together.In the present embodiment, the mounting hole is screw, and the fixture 32 is screw.
The cavity 16 of first cavity 14 and second is separated by dividing plate 17, the bottom of the cavity 16 of the first cavity 14 and second Portion is communicated by a Tunnel-hole 18.The loudspeaker 4 is placed in the second cavity 16, and the vibrating diaphragm is spoken facing to magnetic Steel, the sidepiece of the magnet steel go out acoustic aperture 12 towards side.So, the loudspeaker 4, circuit board 3, the cavity 14 of dividing plate 17 and first and The rear sound chamber 5 of one sealing is formed on the bottom of the second cavity 16.
During the audio cavity structure work that side of the present invention is spoken, voice-frequency signalling current is produced on circuit board 3, the voice-frequency signalling current By loudspeaker 4 voice coil loudspeaker voice coil when, voice coil loudspeaker voice coil forced vibration in magnetic field, meanwhile, the vibrating diaphragm also shakes in the drive of voice coil loudspeaker voice coil It is dynamic, sound wave is produced so as to excite air to produce resonance, due to speaking facing to magnet steel for the vibrating diaphragm in the present invention, thus, it is described The sidepiece of magnet steel is sound face, and sound wave caused by the vibrating diaphragm goes out acoustic aperture 12 by the sidepiece of magnet steel and the side of drain pan 1 and spread out of, from And realize the effect that side is spoken.Because sound wave caused by vibrating diaphragm in the present invention is directly to go out acoustic aperture 12 by magnet steel and side to export, Sound shell need not be led and pilot hole is oriented to sound wave, so as to reduce parts, simplify structure, reduce whole sound chamber knot The thickness and weight of structure, efficiently solve the design of general sound chamber it is complicated, part is more the defects of, be very beneficial for realizing The lightening design requirement of product, can be widely used in ultra thin handset and ultra-thin tablet computer.
Compared to prior art, the audio cavity structure that side of the present invention is spoken is by the way that the vibrating diaphragm of loudspeaker is spoken facing to magnet steel Direction is set, and using the sidepiece of magnet steel as sound face is gone out, so as to reduce parts, is simplified structure, is reduced whole sound chamber knot The thickness and weight of structure, it is very beneficial for realizing the lightening requirement of product.
