. In this device耐震压力表耐震压力表耐震压力表 , a sound wave is captured by a cone膜盒压力表膜盒压力表膜盒压力表 , which connects to one side of an enclosed capsule杭州驾校杭州驾校杭州驾校 . The capsule is bisected by a rubber diaphragmAluminum sheet;Aluminum sheet;Aluminum sheet . On the other side, flammable gas is flowing upward to supply the flameAluminum sheet;Aluminum sheet;Aluminum sheet . The rubber diaphragm acts as a modulator for the gas flow, causing the height of the flame to change with the pressure variations in the sound..
