Research of resonance and prevention of speaker
Guang Wei Hu · Electronic Design Engineering · 2012
In order to improve the work efficiency of speaker,measures such as enhancing the intensity of sound of loudspeaker and reducing the energy consumption caused by vibration as much as possible,which based on speaker's resonance principle,being carried out.According to theoretical arithmetic data which as a basis for the following experiments,the enter resonance frequency be adjusted respectively in several comparative tests to detect the volume(sound energy)of them.The results show that resonance of loudspeaker will take place when the enter resonance frequency equals to the natural frequency and the sound energy is relatively diluted at this time.
