Headphone with acoustic adjustment device

Abstract

The invention discloses a headphone with an acoustic adjustment device. The headphone comprises a hanging frame, a buffer plate, a spacing ring, a leakage hole and the acoustic adjustment device, wherein two ends of the hanging frame are respectively provided with a voice producing body; a loudspeaker is arranged on the buffer plate and divides the buffer plate into a front cavity chamber and a rear cavity chamber; the spacing ring is arranged at the rear side of the loudspeaker and divides the rear cavity chamber into a first rear cavity chamber and a second cavity chamber, wherein the second cavity chamber is communicated with the first rear cavity chamber; the leakage hole is formed at the rear side of the voice producing body and makes the first rear cavity chamber communicated with the outside; and the acoustic adjustment device is communicated between the front cavity chamber and the second rear cavity chamber. In the headphone with the acoustic adjustment device, the front cavity chamber is arranged in the voice producing body and is communicated with an ear canal, the rear cavity chamber comprises the first rear cavity chamber and the second rear cavity chamber which are communicated, and a bassoon is arranged between the front cavity chamber and the second rear cavity chamber and is wrapped at a port of the front cavity chamber by an acoustic damping element, so that an effect of adjusting bass resonant frequency of the headphone is achieved; and when the headphone is matched with an active anti-noise circuit, an excellent anti-noise effect can be achieved.

Description

technical field [0001] The invention relates to the field of earphones, in particular to an earphone in which an acoustic adjustment device is arranged between the front and rear chambers in the earphone to adjust the bass and improve the frequency response. Background technique [0002] With the continuous advancement of science and technology, the development of various electronic products is faster. Among them, the earphone is used as a transmission tool for the connection between the electronic device and the human ear, and is used to transmit sound information to the human ear. The development of the earphone is in addition to the comfort In addition to wearing, more attention is paid to the performance of sound quality. [0003] figure 1 Shown is the current existing headphone, which consists of a shell cover 1 and a shell 2 to form an accommodating space 3. The accommodating space 3 is respectively provided with a circuit board 4 and a speaker 5. The shape of the cir...

Problems solved by technology

[0004] However, although the above-mentioned headphone has a passive noise canceling function, the front and rear chambers of the loudspeaker 5 are divided into a front chamber and a rear chamber, and the front chamber is matched with the earmuffs 6 to connect the ear canal, and the rear chamber is connected to the rear of the loudspeaker 5, but this Headphones need to be designed through the internal structure to improve the low-frequency effect. However, under a specific structure, it is necessary to overcome the obstacles of the spatial structure in order to have better low-frequency acoustic performance.
