Problems solved by technology

Due to the characteristics of materials and processes, this type of damper is usually suitable for large-diameter speakers, and when using this type of damper on small-diameter speakers, such as Image 6 As shown, the resonant frequency F0 and the quality factor Q value of the loudspeaker are high, and the performance of the loudspeaker is relatively poor.

Embodiment 1

[0037] A speaker damper, the damper is made of natural rubber, such as figure 1 As shown, the strut is circular, with a voice coil installation hole in the middle, and a concave-convex pattern similar to the strut shape on the surface. When installing, just put the strut on the voice coil Just go up. The damper of this embodiment is tested with the loudspeaker, such as Figure 7 As shown in the obtained frequency response curve, it can be seen that the low-frequency peak (between 100-200Hz) is relatively low, full and smooth, the low-frequency distortion (near 100Hz) is also very low, and the sound quality of the speaker is good.

Embodiment 2

[0039] A speaker damper, said damper is made of nitrile rubber, such as image 3 As shown, the strut is elliptical, with a voice coil installation hole in the middle, and a concave-convex pattern similar to the strut on the surface. When installing, just put the strut on the voice coil Just go up. The damper of this embodiment is tested with the loudspeaker, such as Figure 8 As shown in the obtained frequency response curve, it can be seen that the low-frequency peak (between 100-200Hz) is relatively low, very plump and smooth, the low-frequency distortion (near 100Hz) is also very low, and the sound quality of the speaker is good.

Embodiment 3

[0041] A speaker damper made of butyl rubber, such as Figure 4 As shown, the damper is in the shape of a racetrack, with a voice coil installation hole in the middle, and a concave-convex pattern similar to that of the damper on the surface, as shown in Figure 5 As shown, when installing, just put the centering piece on the voice coil. The damper of this embodiment is tested with the loudspeaker, such as Figure 9 As shown in the obtained frequency response curve, it can be seen that the low-frequency peak (between 100-200Hz) is relatively low, full and smooth, the low-frequency distortion (near 100Hz) is also very low, and the sound quality of the speaker is good.

Abstract

The invention discloses a centering disk for a loudspeaker. The centering disk is made of a rubber or foamed rubber material. The rubber or foamed rubber material has higher internal loss compared with the ordinary phenolic fabric and has certain stretchability, so that the damping of a loudspeaker vibrating system can be increased in the working process of the loudspeaker and the distortion of the loudspeaker at large amplitude is greatly reduced.

Description

technical field [0001] The present invention relates to loudspeaker parts, especially dampers for small loudspeakers. Background technique [0002] The centering support is used to support the vibration system composed of the loudspeaker voice coil and paper cone, so as to ensure that the voice coil is vertical and not skewed. The concentric rings on the centering strut allow the voice coil to move up and down freely in the magnetic gap without moving laterally, so as to ensure that the voice coil does not collide with the magnetic poles. Science and technology are changing with each passing day, especially the development of electronic technology has made electronic products develop in the direction of small, light and portable. However, due to the miniaturization of various components, the miniaturized speaker has to sacrifice its electro-acoustic performance. For a long time, conventional branching tablets are mainly made of cotton cloth or other chemical fiber material...
