Problems solved by technology

Using wireless data transmission methods such as WiFi, Bluetooth, etc., on the one hand, because wireless data transmission is based on electromagnetic wave transmission in space, in order to resist signal attenuation, interference, etc., there are high requirements for signal power and transmission path, which brings research and development and equipment On the other hand, wireless data transmission is mostly based on open protocols and ports, which brings increasingly prominent security issues accordingly (for example, WiFi transmission leaks personal privacy, Bluetooth transmission steals confidential information, etc.)
With wired transmission, such as USB transmission, etc., the USB interface on mobile devices is limited after all, which cannot meet the growing demand for data transmission between devices.
In addition, if users want to transmit data generated in real time according to their own needs through mobile devices, it cannot be achieved through USB

Abstract

The invention discloses a signal conversion circuit and electronic equipment. The signal conversion circuit includes: a conversion enable circuit, which is used to generate an enable signal for controlling the generation of an audio signal according to the input data signal; a signal generation circuit, which is used to respond to the input enable signal and generate a range of audio signals. According to the present invention, a data signal can be converted into an audio signal conforming to a predetermined frequency range.

Description

technical field [0001] The present invention relates to the technical field of signal processing, and more specifically, to a signal conversion circuit and electronic equipment. Background technique [0002] With the vigorous development of mobile Internet technology and the smart device industry, smart mobile devices such as smartphones, tablets, and smart wearable devices have become an indispensable part of people's lives. There are more and more interactions between smart mobile devices. The demand for data transmission by mobile devices is also increasing. In the prior art, data transmission between smart mobile devices may adopt a wireless data transmission manner or a wired data transmission manner. Using wireless data transmission methods such as WiFi, Bluetooth, etc., on the one hand, because wireless data transmission is based on electromagnetic wave transmission in space, in order to resist signal attenuation, interference, etc., there are high requirements for s...
