a receiver

Abstract

The invention relates to the technical field of receivers, in particular to a receiver which comprises a receiver body, front tuning paper, rear tuning paper and a tuning tube, the receiver body comprises a front cover, a vibrating diaphragm, a voice coil, a basin frame and a magnetic circuit assembly, the front cover and the vibrating diaphragm are connected to form a front cavity, and the vibrating diaphragm and the basin frame are connected to form an inner cavity; The front cover is provided with a first tuning hole communicated with the front cavity, the frame is provided with a second tuning hole, a third tuning hole and a fourth tuning hole communicated with the inner cavity, the front tuning paper is attached to the first tuning hole, the rear tuning paper is attached to the secondtuning hole, the inner cavity is communicated with the fourth tuning hole, and the tuning pipe is communicated with the third tuning hole. The low-frequency, medium-frequency and high-frequency adjustment of the receiver is realized, and the low frequency is further increased, so that the extension of the low frequency is better, the submergence is deeper, the peak and valley of the medium frequency are effectively controlled, the high frequency is increased, the receiver is ensured to obtain better bandwidth and frequency response curve flatness, and the overall performance of the receiver is improved.

Description

technical field [0001] The present invention relates to a receiver. Background technique [0002] With the improvement and popularization of sound performance testing equipment, terminal product manufacturers have higher and higher requirements for sound performance. Earphones and telephones, electronic products with sound that are often used in daily life, have become increasingly popular with the improvement of people's living standards. Improvement and taste improvement require the overall sound effect to reach a higher level, and the receiver, which plays a key role in the sound effect, is the focus of control. It not only requires the improvement of low frequency, but also requires effective control of low, medium and high overall frequency response curves. , improve the overall performance of the receiver. [0003] In the prior art, after the structural design of the receiver is finalized, the low frequency of the original receiver unit can only be reinforced by openi...

Problems solved by technology

[0003] In the prior art, after the structural design of the receiver is finalized, the low frequency of the original receiver unit can only be reinforced by opening tuning holes of different sizes on the back of the receiver, and the high, medium and low frequency response curves of the receiver cannot be effectively adjusted. Make adjustments or reinforcements that affect the overall performance of the receiver
