| 摘要 |
<p>The invention relates to a speaker system which comprises a speaker and a power amplifier, wherein the power amplifier changes received audio electrical signals to amplified voltage signals by power amplification and drives the speaker to generate sound; the speaker comprises a thermal sound-generating element and at least two electrodes which are arranged at intervals and are electrically connected with the thermal sound-generating element, and the at least two electrodes input the amplified voltage signals to the thermal sound-generating element. The speaker system is applicable to the electroacoustic transformation field, has simple structure, can operate in a nonmagnetic environment, and has wider sound-generating frequency range and higher sound-generating intensity.</p> |
