Abstract

The invention relates to a portable pulse sound generator, which includes a battery, a battery charging module, a power management module, a high-voltage electromagnetic switch, a wireless remote controller, a wired switch, a low-voltage electric conversion module, a high-voltage energy storage capacitor, and a polarized magnetic medium. The discharge body; the high-voltage electromagnetic switch controls the conduction between the high-voltage energy storage capacitor and the polarized magnetic medium discharge body; the high-voltage energy storage capacitor stores a high voltage of 5000V, and the polarized magnetic medium discharge body consists of two polarized magnets to form a high-voltage discharge . The invention utilizes high-voltage energy storage to form a discharge on a polarized magnetic medium to generate pulsed sound, which is safe and has high sound energy, and the maximum sound energy can reach 150dB.

Description

technical field [0001] The invention relates to the technical field of acoustics, in particular to a portable pulse sound generator, which is applied to the reverberation time measurement of architectural acoustics and the hearing impairment test in the medical field and the like. Background technique [0002] Reverberation time is a basic parameter for evaluating the sound quality of a hall, the acoustic performance of materials, and noise control. It is an objective parameter related to a clear concept of sound or a good subjective experience. One of the basic methods to obtain this parameter is to use the impulse response integration method to measure the reverberation time, and the pulse sound signal source is one of the basic equipment that must be equipped for this measurement method. [0003] Impulse sound sources play an important role in many fields such as sound absorption, sound insulation and reverberation time measurement in architectural acoustics, as well as t...
