Embodiment 1

[0054] Apply the sounder with airtight ring 200 in the HIFI speaker, such as Figure 6 As shown, it includes: a vibrating plate 100 and an airtight ring 200 .

[0055] One end of the airtight ring 200 is connected to the vibrating plate 100, such as Figure 7 , 8 As shown, the airtight ring 200 includes: a hanging edge 210 , an airtight cavity 220 , and an air-tight barrier 230 .

[0056] Suspension edge 210 is surround in English, also known as "edge", which is a flexible connection suspension part of vibrating parts such as diaphragm and vibration plate 100 and fixed parts such as brackets. It is usually made of rubber and other materials, so it is commonly called "rubber edge".

[0057] Such as Figure 7 As shown, the hanging edge 210 can be stretched and deformed, and the hanging edge 210 is made of rubber or other elastic materials. The airtight cavity 220 is composed of at least two hanging edges 210 that are attached up and down in opposite directions, and the airti...

Abstract

The invention discloses a loudspeaker with an airtight ring used in a HIFI sound box, relates to the technical field of loudspeakers, and includes a vibrating plate and an airtight ring. The air-tight ring includes: hanging edge, air-tight cavity, and air-break compartment. The gas barrier includes a piston. The first air-break interlayer of the present invention has not only played the same lateral support role as Litovsky's support beam (5 in Fig. 3), but the second air-break interlayer can cooperate with the air pressure of the hanging edge and the inner independent space to update the vibrating plate. Good horizontal support, the third air-break compartment can also control the flow and pressure of the gas in the independent space, all of which have achieved the suppression effect on the irregular movement of the vibration plate, reduced the technical effect of distortion, and have good sound reproduction.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a loudspeaker with an airtight ring applied to a HIFI sound box and a method for strengthening damping. Background technique [0002] With the popularization of small and portable speakers, and the small speakers are required to emit lower low-frequency sound waves, the passive radiator design has become the first choice. The current design generally adopts the attached figure 1 The vibrating plate of a flat radiator supported only by its cantilevered sides is shown, rarely used as in the attached figure 2 Traditional loudspeaker type shown, with both sprung and edge-supported passive radiators. And in order to extend the low-frequency response, the tuning frequency of the radiator is very low, so the mass of the radiator is relatively large. In this way, the support control of the radiator is very difficult to use the suspension support alone, and the irregular movement ...
