Description

High-sensitivity anti-interference high-fidelity loudspeaker

Technical Field

The utility model relates to a stereo set technical field especially relates to a high sensitive anti-interference high-fidelity speaker.

Background

A loudspeaker, also called a horn, is a transducer that converts electrical signals into acoustic signals, mainly by vibrating a diaphragm and resonating with the surrounding air to produce sound.

The low-grade plastic loudspeaker is poor in tone quality because the single box body of the low-grade plastic loudspeaker is thin and cannot overcome resonance, and although the wood loudspeaker reduces the tone quality caused by the resonance of the box body, the wood loudspeaker is small in size, large in amplitude when playing bass tunes, large in vibration amplitude, and hot after being electrified for a long time, and line resistance changes, so that the loudspeaker is poor in tone quality effect played in a low-frequency state and easy to distort.
