Abstract

The invention discloses an adaptive audio circuit. The circuit comprises a power supply management module, a Type-C socket module, a switch module, a first PMOS tube, a first NMOS tube, a second NMOStube, a first resistor, a first capacitor; a second PMOS tube, a third NMOS tube, a fourth NMOS tube, a second resistor, a second capacitor, a first diode and a second diode. The invention further discloses a mobile terminal, and the mobile terminal comprises a CPU, a linear voltage-stabilized power supply module and the adaptive audio circuit. The structure is simple, and implementation is easy;basic components are used to solve the routing problem when a USB Type-C earphone is inserted positively and negatively; and the overall cost of the mobile terminal is reduced, and the economic prospect is good.

Description

technical field [0001] The invention relates to the field of audio signal processing, in particular to an adaptive audio circuit and a mobile terminal. Background technique [0002] USB (Universal Serial Bus, Universal Serial Bus) is a serial bus standard connecting computer systems and external devices, and is also a technical specification for input and output interfaces. Widely used in information and communication products such as personal computers and mobile devices, and extended to photographic equipment, digital TV (set-top boxes), game consoles and other related fields. [0003] There are currently four types of USB interfaces: 1, USB Type-A, this interface type is our most common USB interface, mainly used in computers, chargers, mice, keyboards, U disks and other equipment; 2, USB Type-B, this interface type is mainly used in printers and other equipment; 3, Micro-B, mainly used in mobile phones and supporting chargers. 4. USB Type-C. [0004] With the developm...
