Description

Annular dust collector for loudspeaker outer diaphragm

Technical Field

The utility model relates to a speaker technical field particularly, relates to an annular dust collector for speaker outer diaphragm.

Background

The loudspeaker is a transducer for converting an electric signal into an acoustic signal, and the quality of the loudspeaker has great influence on the sound quality. The loudspeaker is the weakest component in the audio equipment, and is the most important component for the audio effect. Loudspeakers are of a wide variety and vary widely in price. The audio frequency electric energy makes the paper cone or the diaphragm vibrate and generate resonance (resonance) with the surrounding air through electromagnetic, piezoelectric or electrostatic effect to make sound. The low-grade plastic sound box cannot overcome resonance due to the fact that the box body is thin, and has no tone quality (a part of designed plastic sound boxes are far better than inferior wood sound boxes); the wooden sound box reduces the sound pollution caused by the resonance of the box body, and the sound quality is generally better than that of the plastic sound box. Generally, multimedia speakers are designed in a two-unit two-frequency-division mode, wherein one smaller speaker is responsible for the output of middle and high tones, and the other larger speaker is responsible for the output of middle and low tones. The material of these two horns should be considered in selecting the loudspeaker: the high pitch unit of the multimedia active sound box takes a soft dome as a main part (in addition, a titanium film dome and the like for simulating a sound source) and can reduce the harsh feeling of high-frequency signals by matching with a digital sound source, thereby giving soft, smooth and fine feeling to people. The multimedia loudspeaker box has more soft ball tops such as a silk film with better quality and a PV film with lower cost. The bass unit determines the characteristics of the sound of the loudspeaker box and is relatively important to select.

After the diaphragm is used for a long time, dust in the diaphragm is gathered, and the dust in the general diaphragm is extremely difficult to clean.

An effective solution to the problems in the related art has not been proposed yet.
