Description

A kind of modified vibration aluminium film loudspeaker

Technical field

The utility model relates to a kind of modifieds to vibrate 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.

The high smart phone loudspeaker of integrated level at present on the market, the U cup used above and oscillation ring are since structure is set The reason of meter, mostly uses the mode for applying glue connection to be connected, and this mode is vibrated due to the easy excessive glue of the relatively narrow glue of glue sites Phenomena such as the problem of piece viscose glue, voice coil viscose glue, and then product can be made noise occur, sound is small, without friction.

Utility model content

To solve the above-mentioned problems, the purpose of the utility model is to provide a kind of structures simply, facilitates raw quality steady Determine, sound quality is good, is provided simultaneously with loudspeaker, the three-in-one rectangular vibration aluminium film loudspeaker of earpiece and vibrating function.

In order to achieve the above objectives, the technical solution of the utility model is as follows: a kind of modified vibration aluminium film loudspeaker, the loudspeaker It is made of front cover, diaphragm, voice coil, bracket, vibrating reed, U glasss, quality loop, washer, magnet, rear cover, weld tabs, it is characterised in that: institute Vibrating reed is stated to be connected to form one with the bracket by way of injection molding；The vibrating reed is in quadrangle, including inner ring, side Shape outer ring, shaker arm；The shaker arm is equipped with four groups；The inner ring is connected with the rectangular outer ring by the shaker arm；Institute It states and opens up several semi-circular grooves on four sides of rectangular outer ring respectively；Circular arc I is machined on the inside of described rectangular outer ring one end；It is described Circular arc II is machined on the inside of the rectangular outer ring other end；The inner ring is in double concave, two sides both ends evagination, intermediate indent； Described U glasss is in convex shape, is made of section I, section II；Described section II is in double concave, two sides both ends evagination, intermediate indent；Institute The section and the interior ring cross-section for stating section II exactly match；Described U glasss is connected by the way of laser welding with vibrating reed；It is described Also injection molding is connected with two panels weld tabs on bracket；The quality loop is square, and centre opens up square through hole I；The bottom of the quality loop The hole II to match with the section of U glasss of the section II is opened up on face.

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；The magnet, is sequentially arranged in U glasss described washer；Described U glasss is fixed on the vibration On movable plate；The quality loop is mounted on the U cup；Described U glasss runs through the quality loop；The rear cover is adhesive in the bracket Lower end surface on.

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) circular arc I is arranged on the rectangular outer ring of the utility model to step down, increases space, be convenient for pad Installation；Setting circular arc II is stepped down, and has effectively been avoided the fillet radian that voice coil is coiled into, has been prevented the sound in operational vibration The generation for the problem of circle collides with vibrating reed and causes noise or tone-off；(3) section II of the U cup of the utility model and vibration The inner ring of movable plate is in double concave, U glasss big with the contact area of vibrating reed, is easy to use the mode of laser welding to connect, while U Cup and vibrating reed are connected using the mode of laser welding, have prevented loudspeaker and have occurred that noise, sound be small, vibrationless problem.
