Detailed Description

To facilitate understanding of those skilled in the art, the structure of the present invention will now be described in further detail with reference to the following examples:

example one

Referring to fig. 2-4, a flattened speaker includes:

the bracket 1 comprises a bottom surface and a side surface which is arranged on the upper side of the bottom surface in a surrounding way;

in this embodiment, the bottom surface may be circular, square or other shapes, and the side surface of the bottom surface is provided with a side surface extending upward, so as to form a structure with an upper opening.

The magnet 2 is arranged on the bottom surface of the bracket 1, and the polarities of the magnet 2 are opposite up and down;

in this embodiment, the shape of the magnet 2 is adapted to the shape of the bottom surface of the holder 1, for example, if the bottom surface is square, the magnet 2 is also square. In the present embodiment, the polarities of the magnets 2 are opposite from each other, that is, the upper portion of the magnet 2 is N-pole and the lower portion thereof is S-stage, or the upper portion of the magnet 2 is S-pole and the lower portion thereof is N-stage, so that the magnetic induction lines of the magnet 2 start from the lower end surface of the magnet 2 to reach the upper end surface of the magnet 2, or the magnetic induction lines of the magnet 2 start from the upper end surface of the magnet 2 to reach the lower end surface of the magnet 2. The washer is not provided in the present application, so that the magnetic induction lines of the magnet 2 are not guided to the side face of the magnet 2.

The vibrating diaphragm 3 is hung on the upper end face of the side face of the support 1, and the vibrating diaphragm 3 is arranged above the magnet 2 at a certain interval;

in this embodiment, the diaphragm 3 has a shape matching the shape of the support 1, for example, if the support has a circular structure, the diaphragm 3 also has a circular structure. In this embodiment, since the washer is not provided, the diaphragm 3 may be provided above the magnet 2 and closer to the magnet 2.

And the voice coil 4 is of a structure that the center of the voice coil 4 is taken as a starting point to be coiled outwards, and the voice coil 4 is attached to the middle part of the vibrating diaphragm 2.

The voice coil 4 of the present embodiment is flattened and planarized, and the voice coil 4 is coiled into a shape like a mosquito coil. The smaller the winding pitch of the voice coil 4 is, the larger the repulsive force or attractive force with the magnet 2 after the voice coil is energized is, and the winding pitch is not limited and can be selected according to circumstances.

Further, the center of the voice coil 4 and the center of the diaphragm 3 are overlapped. With this arrangement, the voice coil 4 can drive the diaphragm 3 to be tensioned at the center thereof or to be away from the magnet 2, so that the vibration direction of the diaphragm 3 can be satisfied as much as possible in the longitudinal direction, thereby preventing the polarization of the diaphragm 3.

Further, the diaphragm 3 includes an outer ring and an inner ring, the outer ring is set to be in an arch shape, and the inner ring is in a plane shape. The domed shape may increase the stiffness of the diaphragm 3.

Further, the voice coil 4 is disposed at the inner ring of the diaphragm 1. The planar shape of the inner ring provides an attachment structure base for the voice coil 4, and the voice coil is also planar so as to uniformly receive the magnetic induction lines emitted by the magnet 2.

Optionally, the diaphragm 3 is a circular structure, the inner ring of the diaphragm 3 is a circular structure, and the voice coil 4 is wound around the diaphragm 3 in an outward circular shape with the center thereof as a starting point.

Further, the bottom surface of the bracket 1 is provided with a plurality of air vents 101.

Further, the magnet 3 is a solid structure with a cylindrical shape, and the vent hole 101 is disposed at a position on the bottom surface of the bracket 1 corresponding to the periphery of the magnet 2. In this embodiment, magnet 3 is cylinder solid construction, does not set up the through-hole in its centre, and consequently the magnetic induction line that magnet 3 can provide is denser, can make 4 intermediate positions of voice coil loudspeaker voice coil also accept the magnetic induction line simultaneously.

Example two

The difference between this embodiment and the first embodiment is that, referring to fig. 5,

optionally, the diaphragm is of a square structure, the inner ring of the diaphragm is of a square structure, and the voice coil is wound and attached to the diaphragm in an outward square mode with the center of the voice coil as a starting point.

The magnet is of a cubic solid structure, and the vent holes are formed in the bottom surface of the support and correspond to the periphery of the magnet.

It should be noted that, the implementation principle and the resulting technical effects of the embodiment are the same as those of the first embodiment, and for the sake of brief description, reference may be made to corresponding contents of the first embodiment.
