Abstract
The present invention discloses a loudspeaker system and an electronics device. The loudspeaker system comprises: a power amplifier, which amplifies an input audio signal; a transducer, connected to the power amplifier, which receives the amplified input audio signal and converts it into a sound wave; a power supply, which provides current to the power amplifier; and a secondary battery, wherein the secondary battery provides extra current to the power amplifier when the power amplifier needs a higher current to actuate the transducer.
Claims6
A loudspeaker system for converting an input audio signal into a sound wave, comprising:
- a power amplifier, configured to amplify the input audio signal;
- a transducer, connected to the power amplifier, configured to receive the amplified input audio signal and convert it into the sound wave;
- a power supply, coupled to the power amplifier directly to provide current thereto;
- and
- a secondary battery,
- wherein the secondary battery is configured to provides extra current to the power amplifier when the power amplifier needs extra current to actuate the transducer,
- wherein the secondary battery is a rechargeable battery, and
- wherein the secondary battery is charged through the power supply when it does not supply the extra current, and stops being charged when it supplies the extra current.
