Embodiment Construction

[0023] In order to further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0024] See Figure 1 to Figure 5 The present invention discloses a speaker equalizer, which includes an equalizer body 14 mounted on a single speaker 10. The inclination angle between the section A at the rear of the upper surface of the equalizer body 14 and the parallel bottom surface of the equalizer body 14 is 5-9°, and the section A at the rear of the upper surface of the equalizer body 14 is high in the front and low in the rear, etc. The part A of the carburetor body 14 facing the horn surface is a U-shaped inclined surface. As the frequency increases, the line array tweeter needs to turn a high-frequency point sound source into multiple point sound sources and reduce the distance between the point ...

Abstract

The invention discloses an equalizer of a loudspeaker. The equalizer is capable of reducing the distance between virtual point sound sources and greatly improving the sensitivity of intermediate frequency coverage area. The equalizer comprises an equalizer body, wherein the front end of the equalizer body is provided with an arc-shaped oblique surface; one side, which is adjacent to the arc-shaped oblique surface, of the surface of the equalizer body is provided with two symmetrical equalizer openings; the middle of the equalizer body is provided with a fan-shaped groove; the concave back surface of the fan-shaped groove is provided with a fan-shaped convex surface; a segment A of the rear part of the upper surface of the equalizer body is provided with a relatively high front part and a relatively low rear part; a section A part, which is opposite to a horn-shaped surface, of the surface of the equalizer body is a U-shaped oblique surface. The equalizer is capable of greatly improving the replay tone quality of a linear array in a sound intermediate frequency band, and meanwhile is relatively low in cost and easy to produce.

Description

Technical field [0001] The present invention relates to the field of audio, in particular to a speaker equalizer. Background technique [0002] The equalizer is an audio signal processing device that can be used in speakers to correct the distortion of the sound frequency caused by the vibration of the sound film to obtain a flat response, thereby improving the clarity and naturalness of the sound. [0003] In order to obtain better sound quality, the method of forming a line array can be used. Due to the characteristics of the line array, a line array is formed. The higher the frequency, the smaller the distance between the point sound sources that make up the line array. Generally, line array speakers All of the high-frequency units are in the form of waveguides, turning a high-frequency point sound source into multiple point sound sources, reducing the distance between point sound sources. But the intermediate frequency unit is different from the high frequency unit. The volume...
