Problems solved by technology

[0003] The loudspeaker is an electro-acoustic transducer. The electric energy makes the diaphragm vibrate through the electromagnetic effect. The vibrating diaphragm resonates with the surrounding air to produce sound. The shape of the diaphragm will affect the sound effect. The existing vibrating diaphragm is in the shape of a truncated cone. In this way, when the conical inclined part on the diaphragm is vibrating and sounding, there will be sharp peaks in the middle and high frequency bands on the frequency response curve, such as the 2000Hz~3000Hz frequency band, which will easily lead to harsh or hoarse sounds, and the original sound will be distorted and the hearing effect will not be good.

Embodiment Construction

[0021] The structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] exist Figure 1-3 Among them, a loudspeaker diaphragm 1 has a conical inclined portion 2, and the conical inclined portion 2 has at least one protrusion 3 protruding toward the front, where the front refers to the surface in which the diaphragm 1 is recessed, Such as figure 2 shown. There are many ways to arrange the protrusions. For example, the protrusions can extend in a ring shape along the circumferential direction of the conical inclined part, or there are multiple protrusions, and the plurality of protrusions can extend along the circumferential direction of the conical inclined part. The directions are spaced apart. In this embodiment, there is a pair of protrusions 3 , and the paired protrusions 3 are symmetrically distributed according to the centerline of the conical inclined portion 2 . On the radial section of the conical incli...

Abstract

The invention discloses a speaker vibrating diaphragm and a speaker comprising the same. As a conical inclining part of the speaker vibrating diaphragm is provided with a bulge, the peak of the middle-high frequency range of a frequency response curve of the speaker can be lowered, the frequency response curve at the middle-high frequency range is relatively smooth, the sound effect of the middle-high frequency range is improved, and the original sound is reflected relatively truly. As holes are formed on the bulge of the vibrating diaphragm, the peak or trough of the middle-low frequency range of the frequency response curve of the speaker can be further lowered, the frequency response curves of the speaker at the middle-high frequency range and middle-low frequency range are both relatively smooth, the sound effect of the speaker is further improved, and the sound is truer and better.

Description

[0001] technical field [0002] The present invention relates to a loudspeaker vibrating membrane and also relates to a loudspeaker comprising the vibrating membrane. Background technique [0003] The loudspeaker is an electro-acoustic transducer. The electric energy makes the diaphragm vibrate through the electromagnetic effect. The vibrating diaphragm resonates with the surrounding air to produce sound. The shape of the diaphragm will affect the sound effect. The existing vibrating diaphragm is in the shape of a truncated cone. In this way, when the conical inclined part on the diaphragm vibrates and sounds, there will be peaks in the middle and high frequency bands on the frequency response curve, such as the 2000Hz~3000Hz frequency band, which will easily lead to harsh or hoarse sounds, and the original sound will be distorted and the hearing effect will not be good. Contents of the invention [0004] The first object of the present invention is to provide a loudspeake...
