Description

A kind of speaker unit

Technical field

The utility model relates to horn arts, and in particular to a kind of speaker unit.

Background technique

Loudspeaker is also known as loudspeaker, is a kind of very common electro-acoustic transducer device, electric signal can be changed into acoustical signal, raised Influence of the performance superiority and inferiority of sound device to sound quality is very big.Loudspeaker is a most weak device in stereo set, and for sound For ringing effect, it is a most important component again.Loudspeaker it is many kinds of, and price differs greatly.Audio electric energy By electromagnetism, piezoelectricity or electrostatic effect make its cone or diaphragm vibration and generate resonance (sympathetic response) with the air of surrounding and issue Sound.

Loudspeaker principle of sound is: voice coil just generates friendship under the function of current after voice coil of loudspeaker is passed through tone currents The magnetic field of change, permanent magnet also generate the constant stationary magnetic field of a size and Orientation simultaneously.The magnetic field as produced by voice coil Size and Orientation is constantly changing with the variation of tone currents, and the interaction in two such magnetic field makees voice coil perpendicular to voice coil The movement of middle current direction, so that vibrating membrane be driven to generate vibration, causes sky by diaphragm oscillations since voice coil is connected with vibrating membrane The vibration of gas and make a sound.The loudspeaker of the prior art, vibrating diaphragm generally uses sheet PP material, but loudspeaker is come It says, loudspeaker issues the part of high pitch mainly in the center of vibrating membrane, and loudspeaker issues the part of bass mainly in vibrating membrane Edge, sheet PP material are difficult to meet the requirement at each position simultaneously, influence high bass effect.
