DRIVING CIRCUIT FOR AUDIO POWER AMPLIFIER AND ELECTRONIC DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240235499 titled 'DRIVING CIRCUIT FOR AUDIO POWER AMPLIFIER AND ELECTRONIC DEVICE

Simplified Explanation: The driving circuit for an audio power amplifier in an electronic device allows the power amplifier to drive both a motor and a speaker, reducing power consumption and cost.

  • The driving circuit includes an audio codec, audio power amplifier, power management integrated circuit (PMIC), transistor, speaker, and motor.
  • The transistor is connected in series with the motor to create a combined body, while the speaker is connected in parallel with the combined body to form a two-in-one device.
  • The audio power amplifier is connected in series with the two-in-one device, along with the PMIC and audio codec.
  • By allowing the power amplifier to drive both the motor and speaker, the need for a separate power amplifier is eliminated, reducing power consumption and cost.

Potential Applications: This technology can be applied in various electronic devices that require audio power amplification, such as smartphones, tablets, laptops, and portable speakers.

Problems Solved: 1. Eliminates the need for a separate power amplifier, reducing power consumption and cost. 2. Simplifies the circuit design by integrating the motor and speaker into a two-in-one device.

Benefits: 1. Reduced power consumption. 2. Lower cost of electronic devices. 3. Simplified circuit design. 4. Improved efficiency in driving both motor and speaker.

Commercial Applications: This technology can be utilized in the development of consumer electronics, automotive audio systems, and industrial equipment where audio power amplification is required. It can lead to cost savings for manufacturers and improved efficiency in electronic devices.

Questions about the Technology: 1. How does the integration of the motor and speaker into a two-in-one device impact the overall performance of the audio power amplifier? 2. What are the potential challenges in implementing this driving circuit in different types of electronic devices?


Original Abstract Submitted

a driving circuit for an audio power amplifier and an electronic device are provided. the driving circuit includes an audio codec, an audio power amplifier (pa), a power management integrated circuit (pmic), a transistor, a speaker, and a motor. the transistor is connected in series with the motor to form a combined body, the speaker is connected in parallel with the combined body to form a two-in-one device, the audio pa is connected in series with the two-in-one device, the pmic is connected in series with the two-in-one device, and the audio codec is connected in series with the audio pa. in the technical solutions provided in embodiments of the disclosure, a power amplifier can drive both the motor and the speaker, so that a power amplifier may be omitted and the power consumption and cost of the electronic equipment may be reduced.
