Description

A kind of moving coil speaker

Technical field

The utility model relates to a kind of moving coil speaker, is specifically related to the small moving-coil loud speaker that a kind of diameter is 45mm.

Background technology

Moving coil type earphone is common, the most common earphone, and its driving unit is exactly a small-sized moving-coil loud speaker substantially, drives vibrating diaphragm (diaphragm) vibration being attached thereto by the voice coil loudspeaker voice coil being in permanent magnetic field. Moving coil type earphone efficiency comparison height, mostly can be the earphone on sound equipment and exports driving, and reliability and durability.

But what exist in existing market wears the Microspeaker that moving coil type earphone uses, external diameter stock size has Ф 30mm, Ф 40mm, Ф 50mm, Ф 57mm, Ф 60mm etc., and for cover aural headphone, Ф 40mm speaker size is excessively little, swept area is relatively less than normal, radiates acoustic pressure not enough, and Ф 50mm speaker size is bigger than normal when pushing away big earphone, complete machine can seem heavier, lightly brief not.

Practical novel content

The technical problems to be solved in the utility model is: proposes a kind of Ф 45mm and improves the moving coil speaker of frequency response curve.

The utility model is the technical scheme solving the problems of the technologies described above proposition: a kind of moving coil speaker, comprise magnetic circuit unit and it is connected to the annular support for carrying diaphragm of described magnetic circuit unit outside, described support is provided with the pcb board for bonding wire and conduction, the external diameter of described support is 45mm, it is provided with in the front of support and the location bone that described pcb board axis extended line coincides, two groups of breather holes offered by two side stand pictures on show of described location bone, the rack surface of bone both sides, described location is all covered with adjustable sound paper, often organize in breather hole the spacing of the first breather hole in first place between the bone of location with often organize in breather hole equal in the spacing of the 2nd breather hole of position, end between pcb board side.

Further, described first breather hole and the 2nd breather hole are circle, and line between the center of circle of described first breather hole to the ring heart of described support and the angle between the Limb lengthening line of described location are 20 degree;

Line between the center of circle of described 2nd breather hole to the ring heart of described support and the angle between the side extended line of described pcb board are also 20 degree.

Further, described diaphragm is made up of ball top and the outer arc portion being connected to outer, described ball top, and described outer arc portion spaced surface is evenly provided with at least 55 road rib lines.

Further, described diaphragm is at least coated with metallic coating on the surface at ball top.

Further, described diaphragm is made up of the identical PAR material layer of shape, PU material layer and PEEK material layer compound.

Further, described diaphragm is made up of PET material.

Further, described diaphragm is made up of PEN.

Further, described diaphragm is made up of PEI material.

Further, described diaphragm is made up of PEEK material.

The beneficial effects of the utility model are:

The utility model gets Ф 40mm loud speaker and the balance of Ф 50mm loud speaker, and a external diameter of development and Design is the loud speaker of Ф 45mm, to adapt to this type of earphone to the demand of structure and outward appearance.

As shown in Figure 2, the adjustable sound paper of conventional loudspeakers support is full wafer adjustable sound paper, easily pastes partially for subsides back of the body glue adjustable sound paper, and carries on the back to the rear being difficult to of glue adjustable sound paper subsides and adjust, adjustable sound paper condemnation factor height. The utility model is on conventional stent basis, add a location bone, movement is slightly done in breather hole position, it is divided into symmetrical two portions, and the angle of both sides, pitch-row limit, four limits locating dowel is all the same, it is convenient to general same back of the body glue adjustable sound paper, makes support the right and left adjustable sound paper can be general in a, it is convenient to paste back of the body glue adjustable sound paper, reduces adjustable sound paper condemnation factor. In structure design with stylish support, near pcb board dual-side breather hole position relatively closer to, the distribution of overall breather hole relatively more disperses, ventilative relative equilibrium, more utilize the balance of vibration simultaneously by the optimization design of size and structure, reach the object improving frequency response curve and characteristic.
