[0037] A speaker is a transducer device that converts electrical signals into sound signals. The speaker is the weakest device in audio equipment. There are many types of speakers. Audio electrical energy is transmitted through electromagnetic, piezoelectric or electrostatic effects to make the paper cone or diaphragm vibrate and resonate with the surrounding air to produce sound.

[0038] In order to better dissipate heat and conduct air flow, existing speakers are provided with openings at the back of the basin frame.
