Problems solved by technology

[0004] The loudspeaker belongs to the electro-acoustic transducer device. The electric energy makes the diaphragm vibrate through the electromagnetic effect, and the vibrating diaphragm resonates with the surrounding air to produce sound. The structure 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 of the diaphragm vibrates and makes sound, there will be sharp peaks in the middle and high frequency bands on the frequency response curve, such as the 1000Hz~10000Hz frequency band, which is easy to cause ear-piercing or hoarse sound, the original sound is distorted and the hearing effect is not good

Embodiment Construction

[0023] The structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0024] exist Figure 1-3 Among them, a loudspeaker diaphragm has a conical inclined portion 1, and a perforation 2 is opened on the conical inclined portion 1, and the perforation 2 is covered with a waterproof sheet 3. image 3 Among them, the waterproof sheet 3 covers the front of the perforation 2, and the front here refers to the surface where the vibrating diaphragm is sunken. The number of perforations 2 can be one or more. When the number of perforations 2 is multiple, a plurality of perforations 2 are distributed at intervals along the circumferential direction of the conical inclined portion 1. In this embodiment, there are at least one pair of perforations 2 , the paired perforations 2 are symmetrically distributed according to the center line of the conical inclined part 1, and each perforation 2 is covered with a waterproof sheet 3, such a...

Abstract

The invention discloses a vibrating diaphragm of a loudspeaker and the loudspeaker comprising the vibrating diaphragm. A cone-shaped inclination part of the vibrating diaphragm of the loudspeaker is provided with a through hole, a waterproof sheet covers the through hole, and therefore peaks of mid-high frequency bands in a frequency response curve of the loudspeaker can be reduced, so that the frequency response curve of the mid-high frequency bands is more smooth, the sound effect is improved, and original sound can be reflected more truly.

Description

[0001] technical field [0002] The present invention relates to a loudspeaker vibrating membrane, and also relates to a loudspeaker comprising the vibrating membrane. [0003] Background technique [0004] 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 structure 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 a sharp peak in the middle and high frequency bands on the frequency response curve, such as the 1000Hz~10000Hz 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. [0005] Contents of the invention [0006] The first object of the present in...
