Description

Loudspeaker adopting novel sound film

Technical Field

The utility model belongs to the technical field of the earphone technique and specifically relates to an adopt new-type sound membrane's speaker.

Background

The micro-speaker comprises a supporting system, a magnetic circuit system and a vibration system. Wherein vibration system includes voice coil loudspeaker voice coil and vibrating diaphragm, and after the voice coil loudspeaker voice coil inserts alternating current audio current, produce the interact power with the magnet in the magnetic circuit, the voice coil loudspeaker voice coil drives the vibrating diaphragm vibration, and compressed air has produced the sound the same with former audio signal wave form. However, in the existing voice coil, the enameled wire is generally wound and overlapped to a certain height and then bonded to the vibrating diaphragm, and the part of the voice coil bonded to the vibrating diaphragm cannot participate in cutting the magnetic induction wire, so that the quality of the voice coil is increased, and the input voltage is consumed, thereby affecting the sound pressure output of the loudspeaker.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a to the not enough of prior art existence, provide a speaker of new-type sound membrane of adoption that reduces voice coil loudspeaker voice coil quality, improves sound pressure output.

In order to achieve the above object, the utility model discloses a technical scheme of the speaker of new-type sound membrane is:

the utility model provides an adopt speaker of new-type sound membrane, includes the support, and support one end is provided with annular cylinder, and annular cylinder sets up the through-hole of acceping the magnetic shield, and magnet has been acceptd to the magnetic shield inner chamber, and the other end of support is provided with the sound membrane, and the sound membrane includes interior sound membrane and outer sound membrane, accompanies the coil between interior sound membrane and the outer sound membrane, and the coil tiles between interior sound membrane and outer sound membrane, and the coil passes through the wiring dish of pin junction rigid coupling in the support, leaves the clearance between interior sound membrane and the magnet. The coil receives alternating current audio current transmitted by the wiring disc through a lead wire to generate a magnetic field, the magnet generates interaction force with the magnet, the magnet is fixed, the coil drives the voice film to vibrate, and compressed air generates sound with the same waveform as an original audio signal. The coil clamped between the inner and outer diaphragms has a relatively light mass, reducing the mass of the entire vibration system, and thus improving the sound pressure output.

Preferably, a plurality of tuning through holes are formed in the support, the tuning through holes surround the annular column body, and the tuning through holes are covered with a tuning net. The tuning net improves acoustic performance.

Preferably, the tuning through hole can be a round hole, a square hole or a long circular arc hole.

Preferably, the inner wall of the annular cylinder body is provided with a limiting step for positioning the magnetic shield. When the magnetic cover is assembled, the spacing step controls the distance between the magnet and the inner sound film.

Preferably, the support is in a ring shape, and limiting protrusions convenient to assemble are arranged on the circumferential surface of the ring shape. During the assembly, spacing arch prevents that annular support from taking place to follow and changeing.

Compared with the prior art, the utility model, have following advantage:

1. the coil clamped between the inner sound film and the outer sound film has lighter weight, so that the mass of the whole vibration system is reduced, and the sound pressure output is improved;

2. the inner wall of the annular column body is provided with a limiting step, so that the distance between the magnet and the inner sound film can be conveniently controlled during assembly;

3. set up spacing arch on ring shape support global, prevent that ring shape support from taking place to follow the commentaries on classics in assembling process, improve work efficiency.

Drawings

FIG. 1 is a schematic diagram of a loudspeaker using a novel sound film;

FIG. 2 is an exploded view of FIG. 1;

fig. 3 is a schematic structural view of the stent.

The voice tuning device comprises a support 1, a limiting protrusion 11, an annular cylinder 12, a through hole 121, a limiting step 122, a tuning through hole 13, a tuning net 2, a magnetic cover 3, a magnet 4, a sound film 5, an inner sound film 51, an outer sound film 52, a coil 6, a lead 7 and a wiring disc 8.

Detailed Description

The present invention will be further clarified by the following description in conjunction with the accompanying drawings, which are to be understood as illustrative only and not as limiting the scope of the invention, and modifications of the various equivalent forms of the invention by those skilled in the art after reading the present invention are within the scope defined by the appended claims.

As shown in fig. 1-3, including the support 1, the support is a ring, the ring has a circumferential surface which is equipped with the limiting protrusion 11 for easy assembly, avoiding the ring support from following the rotation in the assembly process, improving the work efficiency, one end of the support is coaxially equipped with the ring column 12, the ring column is integrated with the support, the support is equipped with 4 tuning through holes 13 around the ring column, the tuning through holes are long arc holes, the long arc holes are covered with the tuning net 2 for improving the acoustic performance, the tuning net is at the same side of the ring column, the ring column is equipped with the through hole 121 for accommodating the magnetic shield 3, the through hole inner wall next to one end of the support is equipped with the limiting step 122 for positioning the magnetic shield, the magnetic shield is a shell with one open end, the magnet 4 is bonded in the inner cavity of the magnetic shield, the magnetic shield and the magnet are installed in the through holes and are abutted against the limiting step, the other end of the, the coil 6 is clamped between the inner sound film and the outer sound film for composite forming, the coil is flatly paved between the inner sound film and the outer sound film, the coil is connected and fixedly connected with a wiring disc 8 of the support through a lead 7, the wiring disc and the support are formed in an injection molding mode at one time, and a gap is reserved between the inner sound film and the magnet.

The utility model discloses a concrete working process and principle:

the voice coil loudspeaker voice coil passes through the alternating current audio current of lead wire access follow wiring dish input, produces the magnetic field, produces the interact power with magnet, and magnet bonds in installing on the support fixed, and the voice coil loudspeaker voice coil drives interior sound membrane and outer sound membrane vibration, and the peripheral air of compression sends the sound the same with former audio signal wave form. The utility model discloses inside arranging the voice coil loudspeaker voice coil in the sound membrane, fused whole vibration system into an organic whole promptly, reduced whole vibration system's quality to can improve efficiency utilization and rate, improve output sound pressure, avoid appearing the frequency response curve low frequency section peak valley and roll over, do benefit to the high-fidelity output of sound, improve the quality of speaker.
