Problems solved by technology

[0005] (1) When the cavity volume of the speaker is constant, the resonant frequency of the speaker is relatively high, so that the mid-high frequency sensitivity of the speaker is relatively high, while the low-frequency sensitivity is relatively low;
[0006] (2) When the cavity volume of the speaker is constant, if you want to reduce the resonant frequency of the speaker and improve the low-frequency sensitivity, you need to increase the vibration quality of the sound film, which will reduce the high-frequency sensitivity of the speaker

Abstract

The invention relates to a loudspeaker and audio equipment and relates to the electroacoustic conversion technology field. The loudspeaker is mainly characterized in that the loudspeaker comprises a basin rack, a magnetic circuit system and a vibration system, wherein the basic rack has an accommodation space, the magnetic circuit system and the vibration system are respectively accommodated in the accommodation space of the basin rack, the magnetic circuit system is connected with the vibration system so as to drive the vibration system to vibrate and sound, and the magnetic circuit system is further driven by the vibration system to vibrate. The audio equipment comprises the loudspeaker. The loudspeaker is advantaged in that not only can low frequency sensitivity of the loudspeaker be improved as the volume of the loudspeaker is fixed, but also high-frequency sensitivity of the loudspeaker is guaranteed to be unchanged.

Description

technical field [0001] The invention relates to the technical field of electroacoustic conversion, in particular to a loudspeaker and audio equipment. Background technique [0002] In audio equipment, a speaker is a commonly used electronic component, mainly used for playing audio signals. [0003] Existing loudspeakers usually include a magnetic circuit system and a vibration system. Among them, the magnetic circuit system is fixed; the vibration system includes a voice coil and a sound membrane. When the voice coil is energized, the voice coil pushes the sound film to vibrate and produce sound under the action of the magnetic field of the magnetic circuit system. [0004] The inventor of the present invention has found that the above-mentioned existing loudspeaker has at least the following problems: [0005] (1) When the cavity volume of the speaker is constant, the resonant frequency of the speaker is relatively high, so that the mid-high frequency sensitivity of the ...
