Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of equalizers, in particular to an equalizer used for a loudspeaker. Background Art
[0002] The speaker, as the heart of the sound system, has the core function of accurately converting audio signals into perceptible sounds. It plays a bridge role in the entire sound system, converting electronic signals into sound waves, allowing beautiful music to permeate the air.
[0003] However, traditional speaker designs are limited in some ways. The projection area of traditional speakers is relatively limited, which makes the sound prone to dispersion and imbalance during the projection process. This dispersion and imbalance is particularly obvious in large space environments. When sound propagates in space, it is easy to diffuse and dissipate due to obstacles, thereby reducing the clarity and three-dimensional sense of audio transmission. In addition, this uneven diffusion also causes trouble for listeners. Due to the differences in volume and sound quality at different locations, listeners may experience different listening experiences at different locations. Some locations may be too noisy, while others may be too weak or even inaudible. This difference not only affects the listener's auditory enjoyment, but may also have a negative impact on the overall effect of the sound system. Utility Model Content
[0004] Based on this, the utility model provides an equalizer for a loudspeaker, which has a simple structure and is easy to use. The diffusion table is designed in the shape of a quadrangular pyramid, and the sound guide surface of the diffusion table is used to guide the sound waves to diffuse and propagate outward better, so that the sound waves can be diffused more evenly during the transmission process, thereby improving the transmission and diffusion characteristics of the sound waves, further enhancing the directivity, and improving the sound quality effect.

[0029] A circular through hole is provided in the middle of the equalizer substrate 10 , and a bridge portion 11 is radially connected to the inner side of the circular through hole on the equalizer substrate 10 . The bridge portion 11 separates the circular through hole into two sound outlet holes 12 , thereby optimizing the propagation direction of the sound.
[0030] In this embodiment, the circular through hole and the speaker 32 are coaxially arranged.
[0031] The equalizer substrate 10 is provided with stopper portions 13 on opposite sides corresponding to one end of the bridge portion 11, and each stopper portion 13 is provided with an arc-shaped concave surface 14 on one side close to the bridge portion 11. The arc-shaped concave surface 14 is used to match and abut the periphery of the speaker 32 to play a stopper role, ensuring that the center of the diffusion platform 20 can be accurately located on the axis of the speaker 32, thereby ensuring the accuracy and directivity of sound propagation.

The diffusion platform 20 is arranged in a quadrangular pyramid shape, wherein the length direction of the diffusion platform 20 is consistent with the length direction of the bridge portion 11. The cross-sectional area of the diffusion platform 20 gradually decreases from the bridge portion 11 toward the speaker 32, which can provide a larger forward projection area, which is beneficial to the diffusion of sound waves and the improvement of directivity.
[0034] Sound guiding surfaces 21 are provided on opposite sides of the diffusion platform 20. The sound guiding surfaces 21 smoothly connect the bridge portion 11 and the side of the sound amplifier 20 facing the speaker 32. The sound guiding surfaces 21 face the sound outlet 12, ensuring that sound waves can be smoothly and unimpededly propagated to the outside along the sound guiding surfaces 21, thereby improving the directivity of the entire equalizer, making the sound more directional and improving the sound quality effect.
[0035] In this embodiment, the angle between the sound guide surface 21 and the surface of the sound amplifier 20 facing the speaker 32 is an obtuse angle. Specifically, the angle ranges from 100 to 130 degrees.
[0036] In this embodiment, a surface of the bridge portion 11 facing away from the speaker 32 and a surface of the amplifier 20 facing the speaker 32 are parallel to each other.
[0037] In this embodiment, the length of the diffusion platform 20 is smaller than the length of the bridge portion 11 , and the width of the diffusion platform 20 is equal to the width of the bridge portion 11 .
[0038] The above-mentioned equalizer for the speaker has a simple structure and is easy to use. The diffusion platform 20 is designed in the shape of a quadrangular pyramid. The sound guide surface 21 of the diffusion platform 20 is used to guide the sound waves to diffuse and propagate outward better, so that the sound waves can be diffused more evenly during the transmission process, thereby improving the transmission and diffusion characteristics of the sound waves, further enhancing the directivity, and improving the sound quality effect.
