Sound from the phone outlet enters the resonance chamber and is amplified, with the bass strengthened. Music is released from two outlets on the left and right, creating a stereo effect. The loudness of the same music can be increased by 12 dB. Ceramic has a long history as a material for musical instruments in China.
