Gramophone

Abstract

The invention discloses a gramophone, comprising a gramophone box body, a disc disposed on the box body, and a control circuit disposed in the box body. The gramophone box body is internally provided with at least one horn device connected to the control circuit, and the bottom cover of the gramophone box body is provided with a resonance film. The lower surface of the bottom cover, corresponding to the resonance film is provided with a plurality of separating plates extending downwardly from the surface. The plurality of separating plates are distributed in a radial manner with the central point of the bottom cover being the center. A sound-leading groove is disposed between each two adjacent separating plates. The invention is advantageous in that the lower surface of the bottom cover of the gramophone is provided with a plurality of sound-leading grooves, which can enable airflow to flow in and out along the sidewall of the sound-leading groove, and thereby the flowing path of the airflow can be standardized, and the mixing or storing of airflow can be prevented; airflow can flow smoothly, and flowing stability of airflow can be enhanced; the sound generated by the vibration of the resonance film will not be affected by external air pressure, and the sound effect of the gramophone can be improved.

Description

technical field [0001] The invention relates to the technical field of audio equipment, and more specifically relates to a phonograph. Background technique [0002] As a kind of classical high-end audio equipment, the phonograph is widely used in many artistic gatherings, and its sound is stored in the arc-shaped groove carved on the plane of the record by acoustic method. A traditional phonograph includes a turntable, a tonearm, a speaker, a control circuit, and a resonant membrane, and the tonearm is provided with a stylus. When playing audio through a phonograph, the record is placed on the turntable, the control circuit controls the turntable to drive the record to rotate, and then swings the tone arm to make the stylus contact with the record. When the stylus moves along the uneven arc groove on the record, the tip of the stylus With the fluctuation of the arc-shaped groove, it vibrates slightly, and the vibration signal is transmitted to the resonance membrane to repr...

AI Technical Summary

Problems solved by technology

[0003] At present, the external airflow of the speaker and the resonance membrane is unstable and chaotic. Because the transmission of sound is closely related to factors such as air pressure and density, the resonance membrane generates energy to squeeze the air while vibrating, and the movement of the air forms an airflow. When the airflow circulates Unsmooth or chaotic operation will affect the normal air pressure, and the sound produced by the vibration of the resonance membrane will be affected, and the function of the resonance membrane will not be fully exerted, affecting the sound effect
