Abstract

The utility model discloses a miniature vibration loudspeaker, including the U cup bottom, the U cup bottom inside set up the top lid and closed the aluminium nail lid, aluminium nail lid top pass through the mutual block in installation arch and PCB board centre of a circle position, the U cup bottom with the aluminium nail lid between install the horn assembly for certain distance has between shell fragment and the magnet piece, the shell fragment passes through the protruding formation central point contact with the magnetic stripe piece that makes of installation of aluminium nail lid, makes the shell fragment amplitude bigger, and the low frequency effect is better, installs and reduces outside vibrations at the internal energy of earphone main part, thereby brings better sound and experiences the effect.

Description

Miniature vibration loudspeaker

Technical Field

The utility model belongs to the technical field of loudspeaker and specifically relates to a miniature vibration loudspeaker are related to.

Background

At present, consumers demand earphones more and more, require higher and more, and numerous earphones bass effect is poor on the market, because magnet piece and shell fragment are hugged closely, the unable earthquake of shell fragment has leaded to phenomenon such as bass effect not good better, consequently, needs to provide a miniature vibration loudspeaker.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a miniature vibration loudspeaker to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a miniature vibration loudspeaker, includes the U cup bottom, the U cup bottom inside set up the top lid and closed the aluminium nail lid, aluminium nail lid top through the mutual block in installation arch and PCB board centre of a circle position, the U cup bottom with the aluminium nail lid between install the loudspeaker subassembly.

As a further technical scheme of the utility model, the loudspeaker subassembly including be located the U bottom of cup inside voice coil loudspeaker voice coil, be located the inside magnet piece of voice coil loudspeaker voice coil and assemble in the aluminium nail shell fragment of covering.

As a further technical scheme of the utility model, aluminium nail lid top in installation bellying cup jointed the china department, the china department compress tightly the shell fragment.

As a further technical scheme of the utility model, the shell fragment circumference be provided with the dead slot of rule such as.

As a further technical scheme of the utility model, the voice coil loudspeaker voice coil lean on U bottom of cup bottom one side set up.

The utility model has the advantages that: through such structure for certain distance has between shell fragment and the magnet piece, the shell fragment passes through the protruding contact of formation central point with the magnetic stripe piece that makes of installation of aluminium nail lid, makes the shell fragment amplitude bigger, and the low frequency effect is better, installs the internal energy that reduces outside vibrations in the earphone main part, thereby brings better sound and experiences the effect.

Drawings

Fig. 1 is a perspective view of the present invention.

Fig. 2 is a schematic diagram of the position of the elastic sheet of the present invention.

Fig. 3 is the schematic view of the aluminum nail cover structure of the present invention.

Wherein: the voice coil loudspeaker comprises a PCB (printed circuit board) 1, an elastic sheet 2, a U-shaped cup bottom 3, an elastic sheet 4, a voice coil 5, a washer 6 and an aluminum nail cover 7.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings and preferred embodiments.

Referring to fig. 1-3, a micro-vibration speaker includes a U-cup bottom 3, the top of the U-shaped cup bottom 3 is covered with an aluminum nail cover 7, the top of the aluminum nail cover 7 is mutually clamped with the circle center of the PCB 1 through a mounting bulge, a horn component is arranged between the U-cup bottom 3 and the aluminum nail cover 7, the horn component comprises a voice coil 5 positioned in the U-cup bottom 3, a magnet block 4 positioned in the voice coil 5 and an elastic sheet 2 assembled on the aluminum nail cover 7, by the structure, a certain distance is reserved between the elastic sheet 2 and the magnet block 4, the elastic sheet 2 forms central point contact with the magnetic strip block 4 through the mounting bulge of the aluminum nail cover 7, make 4 amplitudes of shell fragment bigger, the low frequency effect is better, installs the internal energy that reduces outside vibrations in the earphone main part to bring better sound and experience the effect.

Further, the washer 6 is sleeved on the mounting protrusion above the aluminum nail cover 7, and the washer 6 compresses the elastic sheet 2, so that the elastic sheet 2 can vibrate better.

Furthermore, the circumference of the elastic sheet 2 is provided with an equal-rule empty groove, so that the vibration is convenient to generate audio.

Furthermore, the voice coil 5 is arranged close to one side of the bottom of the U-shaped cup bottom 3, so that the effect of the voice coil 5 is improved.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
