Description

New energy vehicle-mounted low-speed prompt loudspeaker diaphragm

Technical Field

The utility model relates to a loudspeaker diaphragm especially relates to an on-vehicle low-speed suggestion loudspeaker diaphragm of new forms of energy.

Background

The diaphragm, also commonly referred to as a "cone," is a core component of the speaker and is the key to convert the level signal into an audio signal. When the loudspeaker inputs an electric signal, the electric signal drives the vibrating diaphragm to vibrate through the principle of electromagnetic effect, piezoelectric effect or electrostatic effect, so that an audio signal is emitted.

Most of the existing loudspeaker diaphragms are cone-shaped, and are also commonly called 'cone' because the existing loudspeaker diaphragms are made of paper fibers and other materials. However, the surface structure of the contour of the common diaphragm in the market is basically a smooth curved surface, and the structure is not friendly to the elasticity and rigidity of the diaphragm, so that the product is difficult to test in testing or use. Therefore, the elasticity and rigidity of the diaphragm are mainly determined by the material, thickness, curvature and height of the diaphragm, and the use of high-strength material imposes a great pressure on the production and manufacturing cost of the product. On the other hand, the surface area of the diaphragm with the smooth curved surface structure affects the frequency characteristics of the loudspeaker, so that the loudspeaker is difficult to exert the ideal effect of the acoustic performance.

Further, the area of the top surface of the polygonal convex block or the area of the bottom surface of the polygonal groove is smaller than the area of the bottom surface of the polygonal convex block or the area of the opening of the polygonal groove.

Further, the thickness of the polygonal bump or the depth of the polygonal groove increases with the increase of the radian of the outer surface of the diaphragm main body part.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 to 3, it does the utility model relates to a first embodiment of on-vehicle low-speed suggestion speaker vibrating diaphragm of new forms of energy, the vibrating diaphragm includes vibrating diaphragm main part 10, rolls over ring 20 and dangling limit 30, the vibrating diaphragm main part 10 outside links to each other with rolling over ring 20, roll over the ring 20 outside and hang limit 30 and link to each other, vibrating diaphragm main part 10 uses the voice coil loudspeaker voice coil hole site as the center, and the interior concave surface is vibrating diaphragm main part surface, a plurality of concentric annular convex block group 40 of vibrating diaphragm main part 10 surface distribution, concentric annular convex block group 40 includes a plurality of polygon lugs 41 of interval arrangement, the size of polygon lug 41 is crescent from vibrating diaphragm main part 10 center to the outside.

The polygonal bump 41 has a prism-like structure, the area of the top surface of the polygonal bump 41 is smaller than the area of the bottom surface of the polygonal bump 41, the corner positions of the polygonal bump 41 are provided with rounded corners, and the support structure of the polygonal bump 41 enables the surface of the vibrating diaphragm main body portion 10 to bear a large force.

The area of the bottom surface of the polygonal bump 41 increases with the increase of the radius of the concentric ring-shaped bump group 40, so that the concentric ring-shaped bump group 40 is arranged tightly. The height of the polygonal bump 41 increases with the increase of the curvature of the outer surface of the diaphragm body 10.

A plurality of salient points 31 are arranged on the top surface of the suspension edge 30. The salient points 31 are hemispherical, and the salient points 31 are arranged at intervals in a staggered mode, so that the suspended edge 30 is embedded and fixed with the loudspeaker outer support, and the diaphragm is reduced from moving along the transverse direction.

As shown in fig. 4 to 5, it is the second embodiment of the new energy vehicle-mounted low-speed prompt loudspeaker diaphragm of the present invention, the structure of the present embodiment is basically the same as that of the first embodiment, and the difference lies in that: the concentric annular convex block group 40 in the first embodiment corresponds to the concentric annular groove group 40a in this embodiment, the concentric annular groove group 40a includes a plurality of polygonal grooves 41b arranged at intervals, and the size of the polygonal grooves 41b gradually increases from the center to the outer side of the diaphragm main body portion 10.
