Description

Composite sound film loudspeaker monomer

Technical Field

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

Background

The loudspeaker is a transducer for converting an electric signal into an acoustic signal, and the quality of the loudspeaker has great influence on the sound quality. The loudspeaker is the weakest component in the audio equipment, and is the most important component for the audio effect. Loudspeakers are of a wide variety and vary widely in price. The audio frequency electric energy makes the paper cone or the diaphragm vibrate and generate resonance (resonance) with the surrounding air through electromagnetic, piezoelectric or electrostatic effect to make sound.

With the advent of the mobile internet era, the electronic products are updated more and more rapidly, and people have higher and higher requirements on various aspects of performance of the electronic products, one of which is a high-quality music function, so that the performance of an electroacoustic system needs to be continuously improved, and a high-quality loudspeaker module is one of necessary conditions for realizing the high-quality music function.

The common loudspeaker products adopted in the current market are mainly characterized in that: (1) three magnetic structures, PEEK sound film, (2) single magnetic structure, ordinary cloth film. Both of these products have the disadvantages of weak low and high frequencies, low intermediate frequency and high cost.

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: the composite sound film loudspeaker monomer has rich low-frequency and high-frequency auditory sensations, can effectively reduce or even avoid sound film polarization, and has small noise and good sound effect.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a compound sound membrane speaker monomer, including the basin frame of taking the cavity, the below of basin frame is equipped with the magnetism bowl, the top of basin frame is equipped with the sound membrane, be equipped with compound cloth layer on the ball top upper surface of sound membrane, be equipped with central magnet steel in the cavity of basin frame, be equipped with rather than complex center polar plate on the center magnet steel, the both sides limit of center magnet steel all is equipped with the side magnet steel, be equipped with on the side magnet steel rather than complex side polar plate, interval L has between center magnet steel and the side magnet steel, be equipped with the voice coil loudspeaker voice coil in the.

The voice coil loudspeaker voice coil in this application can also be hollow voice coil loudspeaker voice coil for ordinary voice coil loudspeaker voice coil, and hollow voice coil loudspeaker voice coil indicates the voice coil loudspeaker voice coil that does not have skeleton and lead silk thread, because the voice coil loudspeaker voice coil does not have skeleton and lead silk thread, lead silk thread not with external circuit connection, so the free other parts of speaker need not dodge the design, this makes the free structural design of speaker become simple, the free volume of speaker reduces to can reduce effectively and avoid the polarization of bubble cotton sound membrane even, the noise is little, sound effect is good.

Further, compound cloth layer includes silk cloth layer, silica gel layer and PU layer, the upper surface on silica gel layer on be equipped with the silk cloth layer, be equipped with the PU layer on the lower surface on silica gel layer.

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

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

Furthermore, the shape of the cross section of the voice coil is the same as that of the central magnetic steel.

The utility model has the advantages that: the utility model has abundant low-frequency and high-frequency auditory senses, can effectively reduce or even avoid the polarization of the sound film, has small noise, good sound effect and higher loudness; the cost is reduced more.
