Description

Loudspeaker capable of improving high-frequency response

[ technical field ] A method for producing a semiconductor device

The utility model relates to a speaker technical field especially relates to a can promote speaker of high audio frequency response.

[ background of the invention ]

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 drum paper or the diaphragm vibrate and generate resonance (resonance) with the surrounding air through the electromagnetic, piezoelectric or electrostatic effect to produce sound.

Many of the previous products have been treated with coaxial speakers (treble is placed inside bass and on the same axis of the two speakers) in order to obtain a wider frequency response and a smaller installation space, and the requirement for a point source (high bass is required to be emitted at one point).

If the treble is arranged in front of the bass, most of sound transmission of the bass paper cone can be shielded, so that the difference of tone quality is caused (if the treble with small caliber is used, the effect cannot be achieved, and the treble is arranged at the back, the installation depth is increased, the universality is reduced.
