Description

A kind of vibration aluminium film loudspeaker

Technical field

The utility model relates to a kind of vibration aluminium film loudspeaker.

Background technique

With popularizing for people's smart phone, people are higher and higher to smart phone requirement, not only want audio well also outer The thin price of shape is low, and this requires smart phone loudspeaker to improve integration degree to adapt to the requirement in space and cost.City at present The smart phone loudspeaker that audio on face is good, thickness is thin are all the loudspeaker of simple function, and the three-in-one loudspeaker (tool that integrated level is high Standby loudspeaker, earpiece, motor function) since audio is poor, size is only used for greatly on the functional mobile phone that will be eliminated.Smart phone There is an urgent need to find the smart phone loudspeaker that a audio is good, size is small, integrated level is high for producer.

Utility model content

To solve the above-mentioned problems, that the purpose of the utility model is to provide a kind of audios is good, size is thin and is provided simultaneously with The three-in-one rectangular vibration aluminium film loudspeaker of loudspeaker, earpiece and motor function.

In order to achieve the above objectives, the technical solution of the utility model is as follows: a kind of vibration aluminium film loudspeaker, the loudspeaker are by preceding Lid, diaphragm, voice coil, bracket, vibrating reed, U glasss, quality loop, washer, magnet, rear cover, weld tabs composition, it is characterised in that: the branch Aperture among frame；The vibrating reed is connected to form one by way of injection molding with the bracket；The vibrating reed is in four sides Shape, including rectangular inner ring, rectangular outer ring, shaker arm；The shaker arm is equipped with four groups；The rectangular inner ring and the rectangular outer ring It is connected by the shaker arm；Several semi-circular grooves are opened up respectively on four sides of the rectangular outer ring；Described rectangular outer ring one end Inside be machined with circular arc I；Circular arc II is machined on the inside of the rectangular outer ring other end；Also injection molding is connected on the bracket Two panels weld tabs；The quality loop is square, and centre opens up square through hole.

Further, the voice coil is bonded on the diaphragm, is installed along on the front cover with the diaphragm；Before described Lid is mounted on the front end face of bracket, is heated and is fixed using cylindrical hot molten column；The magnet, is sequentially arranged at the U at washer In cup；Described U glasss runs through and is fixed on the vibrating reed；The quality loop is mounted on the vibrating reed；Described U glasss runs through The quality loop；The rear cover gluing is bonded on the lower end surface of the bracket using laser；The front cover is without before drawing side Lid.

The beneficial effects of the utility model are: (1) the utility model, which provides one kind, is provided simultaneously with loudspeaker, earpiece and vibration The square horn of function；(2) in quadrilateral structure, vibrating reed is also in quadrangle to the bracket of the utility model simultaneously, relatively using tradition Circular vibration piece, the size of loudspeaker can be done smaller, this utility model uses internal-welded type structure, therefore the size of loudspeaker can It is thinner with what is done；(3) front cover of the utility model is without the design of drawing side, and so matching used diaphragm size can be done Bigger, outer diameter even can be accomplished to flush with front cover size, be much larger than traditional design, effectively promote the utilization rate of diaphragm； The more traditional promotion of vibration ring width of diaphragm simultaneously by about one time, the more conducively promotion of product audio and the promotion of bass (4) Open up several semi-circular grooves respectively on four sides of the vibrating reed of the utility model so that vibrating reed and bracket be molded connect when more It is easy to operate, it connects stronger；(5) circular arc I is arranged on the rectangular outer ring of the utility model to step down, increases space, is convenient for The installation of pad；(6) circular arc II is arranged on the rectangular outer ring of the utility model to step down, has effectively avoided what voice coil was coiled into Fillet radian has prevented the generation for the problem of voice coil and vibrating reed collide and cause noise or tone-off in operational vibration.
