Description

Novel loudspeaker monomer

Technical Field

The utility model belongs to the technical field of the electroacoustic conversion technique and specifically relates to a novel speaker monomer.

Background

In recent years, with the development of thinner speakers, there is a demand for parts and components with a reduced height while maintaining performance. The products adopting the foam cotton sound film in the market at present are mainly characterized by a single magnetic structure, a track-shaped sound film and a structure with a framework or silk threads, and have the defects of high height, high distortion and high cost.

However, the thinning of the speaker body inevitably causes the overall strength of the speaker body to be reduced, and the speaker body is likely to be weak in strength, deformed, and the like, and finally affects the acoustic performance of the speaker. In addition, in the process of testing the performance of the single loudspeaker, if the strength is weak, the phenomena of test failure and distortion can be caused.

Therefore, it is very necessary to provide a novel diaphragm, and the performance of the loudspeaker can be ensured to a certain extent after the loudspeaker is thinned.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: to provide a sound box which can be lowered in height and can be easily fitted into a sound cavity; the distortion of a low-frequency part is reduced by the structure of the square foam sound film; after the framework and the lead wire are eliminated by the hollow voice coil, the cost is reduced more.

The utility model provides a technical scheme that its technical problem adopted is: a novel loudspeaker unit comprises a basin frame with a cavity, main magnetic steel is arranged in the cavity of the basin frame, a magnetic bowl is arranged below the basin frame, a foam sound film with a square cross section is arranged above the main magnetic steel, secondary magnetic steels are arranged on two side edges of the main magnetic steel, a main pole plate matched with the main magnetic steel is arranged on the upper surface of the main magnetic steel, a secondary pole plate matched with the secondary magnetic steel is arranged on the secondary magnetic steel, a gap is arranged between the main magnetic steel and the secondary magnetic steel, a hollow voice coil is arranged in the gap, the hollow voice coil is a voice coil without a framework and a nylon wire, because the voice coil is not provided with the framework and the silk thread wire which is not connected with an external circuit, other parts of the single loudspeaker body do not need to be subjected to avoidance design, the structural design of the single loudspeaker body is simplified, the volume of the single loudspeaker body is reduced, and can reduce effectively even avoid the cotton sound membrane polarization of bubble, the noise is little, and the sound effect is good.

Furthermore, the basin frame and the magnetic bowl are fixed by welding through a soldering lug.

Furthermore, the main magnetic steel and the hollow voice coil are coaxially arranged.

Furthermore, the cross section of the hollow voice coil is the same as that of the main magnet steel.

Furthermore, a flexible circuit board is arranged below the magnetic bowl.

The utility model has the advantages that: after the utility model adopts the novel structure, the height can be reduced, and the sound cavity can be more easily arranged; the distortion of a low-frequency part is reduced by the structure of the square foam sound film; after the framework and the lead wire are omitted, the cost is reduced greatly, the polarization of the foam sound film can be effectively reduced or even avoided, the noise is low, and the sound effect is good.
