Abstract
The utility model relates to a loudspeaker, and provides a loudspeaker with an auxiliary membrane, which aims to solve the problems of insufficient rear sound cavity, high improvement cost and low yield of the existing loudspeaker.
Description
Technical Field
The utility model relates to a loudspeaker, in particular to a loudspeaker with a secondary membrane.
Background
Along with the continuous development of communication equipment and the continuous improvement of the consumer ability of people, the requirements of people on the audio effect of electronic products are also higher and higher, the music is more graceful, the voice is more clear, and the like. The current industry conditions are:
1. the rear sound cavity is not enough, and sound-absorbing cotton or even Bass powder is needed to be added for low-frequency promotion, so that the cost is increased;
2. the monomer itself raises the low frequency but typically results in a loss of yield.
In summary, the existing loudspeaker has the problems of insufficient rear sound cavity, high improvement cost and low yield.
Disclosure of Invention
The utility model aims to solve the technical problems that: in order to solve the problems of insufficient rear sound cavity, high improvement cost and low yield of the traditional loudspeaker, the loudspeaker with the auxiliary membrane is provided.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides a take speaker of vice membrane, includes voice coil loudspeaker voice coil and basin frame, the voice coil loudspeaker voice coil is long strip that has long side and short side, all is provided with at least one vice membrane on long side and the short side of voice coil loudspeaker voice coil, vice membrane and voice coil loudspeaker voice coil set up in the basin frame.
Further, the basin frame also comprises welding pieces, the welding pieces and the basin frame are integrally formed, the number of the welding pieces is two, the basin frame is in a strip shape with long sides and short sides, and the welding pieces are respectively arranged on the short sides of the two sides of the basin frame.
Further, still include main sound membrane, flexible circuit board, polar plate, magnet steel and magnetism bowl, main sound membrane sets up the front end at flexible circuit board, and flexible circuit board's rear end sets up the voice coil loudspeaker voice coil, polar plate and magnet steel paste each other and set up in the voice coil loudspeaker voice coil, and magnetism bowl cover is established in the voice coil loudspeaker voice coil outside, and main sound membrane, flexible circuit board, voice coil loudspeaker voice coil, polar plate, magnet steel and magnetism bowl set up in the basin frame simultaneously.
Further, the polar plate, the magnetic steel and the magnetic bowl form a magnetic circuit unit, and the magnetic circuit unit is a single magnetic circuit.
Further, the auxiliary membrane is of a strip-shaped structure with an omega-shaped end face, the arc-shaped bending part is sleeved on the voice coil, and the outwards protruding parts on the two sides are matched with the groove on the inner side of the basin frame.
Further, when the number of the sub-films is single on each side, the sub-films are disposed at the intermediate positions of the long sides and the short sides of the voice coil.
The loudspeaker with the auxiliary film has the beneficial effects that the vibration unit (the voice coil, the sound film, the flexible circuit board and the auxiliary film) brings a good low-frequency effect, after the design mode with the auxiliary film is used, the vibration of the loudspeaker can be balanced well to bring high-quality audio, meanwhile, the yield and the production efficiency of a production line are ensured, and the welding lug is adopted to replace the traditional connecting wire or the flexible circuit board, so that the resonance risk of an electronic wire when the electronic wire is routed in the loudspeaker is reduced.
