Embodiment 1

[0033] Embodiment 1, with reference to Figure 1 to Figure 8 as shown,

[0034] Such as figure 1 and image 3 As shown, this embodiment provides a gas-reinforced vibrating plate structure 10 , which mainly includes a front vibrating plate 100 , a rear vibrating plate 200 and a first connecting ring 110 .

[0035] Edges of the front vibration plate 100 and the rear vibration plate 200 are sealed and connected, and a sealed gas-filled cavity is formed between the front vibration plate 100 and the rear vibration plate 200 .

[0036] The first connecting ring 110 is arranged in the gas-filled cavity, and at the same time keeps connected with the inner surfaces of the front vibrating plate 100 and the rear vibrating plate 200 , the first connecting ring 110 divides the gas-filled cavity into a central cavity 300 and an annular cavity 400 ; The first connecting ring 110 is provided with a plurality of air holes 111, so that the central cavity 300 and the annular cavity 400 communic...

Embodiment 2

[0058] Embodiment 2 refers to Figure 9 as shown,

[0059] The loudspeaker 60 provided by the embodiment of the present invention has the same realization principle and technical effect as that of the first embodiment. For a brief description, reference may be made to the corresponding content in the first embodiment for the parts not mentioned in this embodiment.

[0060]The loudspeaker 50 obtained through the above design is basically sufficient for use, but in line with the purpose of further improving its functions, the designer has made further improvements to the device.

[0061] Further, in this embodiment, the voice coil 520 includes a first voice coil 610 and a second voice coil 620 located at different positions in the axial direction of the voice coil tube 530 .

[0062] In order for the power amplifier to control the vibration of the speaker 60 more precisely, a high-power coil as the driver is set as the first voice coil 610, and another light and highly sensitiv...

Abstract

The invention provides a gas reinforced vibrating piece structure which comprises a front vibrating piece, a rear vibrating piece and a first connecting ring, wherein the edges of the front vibratingpiece and the rear vibrating piece are connected in a sealed mode; a sealed gas filling cavity is formed between the front vibrating piece and the rear vibrating piece; the gas filling cavity is filled with gas, so that the front vibrating piece and the rear vibrating piece are kept in a preset shape; the first connecting ring is arranged in the gas filling cavity and is connected with the inner surface of the front vibrating piece and the inner surface of the rear vibrating piece at the same time; the first connecting ring divides the gas filling cavity into a central cavity and an annular cavity; the first connecting ring is provided with a plurality of air holes, so that the central cavity is communicated with the annular cavity. Through the cavity structure, gas with a certain pressureis filled, so that the front and rear vibrating pieces are kept tensioned at all times, the strength of the vibrating pieces is enhanced, and the deformation of the vibrating pieces during vibrationis reduced.

Description

technical field [0001] The invention relates to the field of loudspeakers, in particular to a gas-reinforced diaphragm structure and a loudspeaker. Background technique [0002] At present, in order to improve the sound quality, vibrators of various materials and shapes emerge in endlessly in the single speaker, including cone type, spherical concave type, and nearly flat type. The materials include paper, plastic film, and aluminum. Lightweight metals such as titanium, braided materials such as aramid fiber and carbon fiber, and single-layer and composite multi-layer structures. All materials, shapes and structures are aimed at light weight and optimal strength at the same time, so as to ensure that the vibrating plate responds quickly and does not deform when it is vibrated by the force of the voice coil. Distortion of the diaphragm, especially at a distance from the voice coil junction, is very noticeable, causing distortion. The larger the caliber of the speaker, the h...
