Arc-shaped vibrating diaphragm and air kinetic energy loudspeaker with same

Abstract

The invention discloses an arc-shaped vibrating diaphragm and an air kinetic energy loudspeaker with the vibrating diaphragm. The cross section of the formed vibrating diaphragm is in the shape of an arc, and a circuit is arranged on the vibrating diaphragm. The air kinetic energy loudspeaker with the vibrating diaphragm comprises a shell in which a magnet frame, the vibrating diaphragm and two vibrating diaphragm frames at the two ends of the vibrating diaphragm are installed, the upper end and the lower end of the vibrating diaphragm are fixed to the vibrating diaphragm frames respectively, and the left end and the right end of the vibrating diaphragm are fixed to the magnet frame which is provided with a plurality of permanent magnets arranged in the height direction of the vibrating diaphragm. The air kinetic energy loudspeaker with the vibrating diaphragm has the advantages that sound radiation is uniform, a sound field is wide, an expansion angle is large, a spreading diameter is large, sound energy density in a treble is large, a frequency response range is wide, and sensitivity and efficiency are high.

Description

technical field [0001] The present invention relates to a loudspeaker. Background technique [0002] As we all know, speakers are composed of speakers of different specifications (also called units or transducers) installed in a designed cabinet (box). A complete sound system is usually formed by a two-way or three-way crossover network composed of different speakers (units) such as treble, midrange, and bass. A speaker composed of a tweeter and a woofer belongs to a two-way frequency division system; a speaker composed of a tweeter, a midrange speaker, and a woofer belongs to a three-way frequency division system. It can be seen that no matter what kind of audio system, speakers are inseparable, especially tweeters. [0003] In the prior art, the most common one is a dome tweeter, and its sound radiation is a point sound source and a spherical wave, which has the following disadvantages: [0004] 1. The diaphragm area is small. [0005] 2. The radiation efficiency is lo...

AI Technical Summary

Problems solved by technology

[0004] 1. Small diaphragm area

[0005] 2. Low radiation efficiency

[0006] 3. It is easy to produce phase distortion and linear modulation distortion

[0007] 4. The burden on the power amplifier system is large

[0009] 1. The radiation of sound energy is uneven, the sound field is narrow, and the diffusion angle is not wide enough

[0010] 2. The sound energy density in the treble area is small, not full enough, and the propagation diameter is short

[0011] 3. Narrow frequency response range (sound range)

[0012] 4. The power and sound pressure level (loudness level) are relatively low
