With these arrangements, the speaker device can have improved bass performance in the entire low-frequency band instead of being limited to only a few low-frequency points.

Abstract: A power-saving monitoring circuit is applied in an electrostatic earphone having a thin film and a plurality of electrode plates. In the power-saving monitoring circuit, an input unit receives an audio frequency signal; an output unit outputs the audio frequency signal to the electrode plates through; a detection unit detects the audio frequency signal and generates a control signal corresponding to the audio frequency signal to control a switch unit coupled to a power supply unit; a switch unit supplies a first voltage generated by the power supply unit to the driving module; a driving module converts the first voltage into a second voltage to drive the thin film. Since the switch unit cannot supply the first voltage to the driving module through, the driving module needs not to convert the first voltage. The electrostatic earphone is driven by the audio frequency signal automatically to achieve the power-saving effect.

Abstract: A noise-canceling sound playing structure includes a noise canceling mechanism having at least one filtering and phase-reversing unit, an amplifier, and a power supply unit; and a sound output mechanism having at least one enclosure. The enclosure has a first speaker arranged therein and connected to the amplifier, a second speaker arranged therein and connected to an external sound player, and a microphone mounted thereon and connected to the filtering and phase-reversing unit. A chamber is defined in the enclosure between the first and second speakers and the microphone. External noise signals are picked up by the microphone and sent to the noise canceling mechanism for processing at the filtering and phase-reversing unit and the amplifier to thereby produce phase-reversed signals, which are sent to the first speaker to cancel out external noise without being mixed with the musical sound transmitted from the external sound player to the second speaker.
