Detailed Description
Specific embodiments of the present invention will be described in further detail below based on the drawings. It should be understood that the description herein of embodiments of the utility model is not intended to limit the scope of the utility model.
Referring to fig. 1 to 5, the split type partially-overlapped high-elasticity foam sound film provided by the present invention includes a sound film main body 10, a rear cover 20 partially overlapped with the sound film main body 10, and a hanging edge portion 30 partially overlapped with one side of the rear cover 20 away from the sound film main body 10.
The sound film main body 10 is partially spherical, the rear cover body 20 is trumpet-shaped, and the overhanging edge part 30 is annular.
The outer edge of the diaphragm body 10 is bent toward the convex surface of the diaphragm body 10 to form a first abutting ring 11.
The first abutment ring 11 of the diaphragm body 10 is bonded to the middle of the top surface of the rear cover 20 such that the bottom of the rear cover 20 is located below the diaphragm body 10.
A circular first opening 21 is formed in the bottom center of the rear cover 20. A connecting hole 22 is formed on a circumferential side wall of the bottom of the rear cover body 20 for a cable to pass through.
The bottom of the rear cover 20 is extended with a connection ring 23 at the edge of the first opening 21 towards the direction far away from the sound diaphragm main body 10, so as to facilitate the positioning and installation of the rear cover 20.
The middle portion of the skirt portion 30 is bent upward (i.e., toward the convex surface of the diaphragm body 10) to form a bent ring 31. The inner side of the bending ring 31 is provided with a second abutting ring 32 parallel to the rear cover 20, and the second abutting ring 32 is located on the side of the rear cover 20 far away from the first abutting ring 11 and is bonded with the rear cover 20. In the present embodiment, the overhanging portion 30 is a high-density foam ring.
An outer edge 33 protrudes from the side of the overhang portion 30 away from the second abutment ring 32, and the outer edge 33 is used for connecting to an external bracket.
A drum-shaped buffer cavity 40 is formed between the rear cover body 20 and the sound diaphragm main body 10, and the buffer cavity 40 can prevent sound emitted by the sound diaphragm main body 10 from being transmitted backwards to directly act with a rear metal part to generate sharp metal sound.
Compared with the prior art, the split type locally-superposed high-elasticity foam sound film comprises a locally-spherical sound film main body 10, a rear cover body 20 which is trumpet-shaped and is locally superposed with the sound film main body 10, and a suspended edge part 30 which is annular and is locally superposed with one side of the rear cover body 20, which is far away from the sound film main body 10; the bottom of the rear cover body 20 is positioned below the sound film main body 10, and a circular first opening 21 is formed in the center of the bottom of the rear cover body 20; the middle part of the overhanging part 30 is bent upwards to form a bending ring 31; an outer edge portion 33 protrudes outside the bending ring 31. The sound film main body 10, the rear cover body 20 and the suspended edge part 30 are partially overlapped, so the volume is small, the suspended edge part 30 is a high-density foam ring, the weight is light, the supporting strength and the elasticity are high, the climbing of distortion is inhibited, the tone quality is good, and the supporting balance is better while the smoothness is not lost.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, and any modifications, equivalents or improvements that are within the spirit of the present invention are intended to be covered by the following claims.
