Abstract

The article describes the effect of electroacoustic transducer frequency band expansion. The effect appears when a transducer is affected by electric voltage in the form of meander. A noise meter is used to measure the levels of low-frequency and high-frequency sound pressure produced by electroacoustic transducer under the influence of electric voltage in the form of meander. Based on experiments, the levels low-frequency and high-frequency sound pressure rose by 10-20 dB.
