Full-band high-tone-quality plane resonance loudspeaker with sound beam and sound tunnels

Abstract

The invention discloses a full-band high-tone-quality plane resonance loudspeaker with a sound beam and sound tunnels. The loudspeaker comprises a vibrating diaphragm which is in a plane shape, the outer edge of the vibrating diaphragm is combined with an outer frame of the loudspeaker through an elastic connecting piece, and the middle of the vibrating diaphragm is arranged corresponding to a sound source; at least one surface of the vibrating diaphragm is provided with a first groove and a second groove, and the two grooves are crossed and communicated with each other to equally divide the surface of the vibrating diaphragm into four resonance areas. the diaphragm is also provided with a sound beam assembly at the center of the same side surface provided with the two grooves, and the sound beam assembly comprises a plurality of strip-shaped sound beam components which are arranged at two sides of the first groove and two sides of the second groove in pairs. and the two grooves respectively form audio tunnels on the surface of the vibrating diaphragm. According to the invention, the vibrating diaphragm is changed from the original free vibration mode to the current standard vibration mode, and the problems that the high-pitch area of the planar resonance loudspeaker cannot be lightened and the low-pitch area is thick and round enough are solved from the angles of vibration, resonance and sound production. Practice proves that the improved design scheme has outstanding substantive features and remarkable technical progress.

Description

technical field [0001] The invention relates to a planar resonant loudspeaker, in particular to a full-frequency high-quality planar resonant loudspeaker with a sound beam and a sound tunnel. Background technique [0002] The resonant speaker is a special speaker used in electronic products (such as smart speakers). It is usually used in conjunction with other speakers in the audio system. It can be assembled on the side of the main speaker to play an auxiliary role in improving the sound quality. Enhanced and boosted to help restore the original sound and improve sound fidelity. Such as figure 1 , 2 As mentioned above, the diaphragm 1 of the traditional planar resonant speaker is connected to the outer frame 3 of the speaker through the elastic connector 2 (rubber ring can be selected) around the diaphragm 1 . When the speaker is working, the vibration of the diaphragm 1 pushes the air, thereby emitting sound. [0003] The common problems of traditional planar resonant ...

AI Technical Summary

Problems solved by technology

[0003] The common problem of traditional planar resonant speakers is: the speaker has an inherent resonant frequency when making sounds. After exceeding a certain range of the resonant frequency region, the high-pitched area will not be bright, and the low-pitched area will not be thick and round enough to achieve high-quality timbre in the full frequency range.

The main reason is that the current loudspeaker diaphragm cannot meet the good broadband vibration from the high-pitched range to the low-pitched range, that is, it cannot adapt to the resonance and vibration of the wide-ranging frequency changes in the high-pitched, mid-range, and low-pitched ranges at the same time.

In summary, the structural design of the traditional planar resonant speaker is unreasonable, which is not conducive to the good sound wave vibration of the diaphragm from the high-pitched range to the low-pitched range.
