Abstract

The invention belongs to the technical field of electronic circuits, and provides an audio playing device with a power bank function. The audio playing device is provided with a radio frequency modulefor receiving or transmitting a radio frequency signal, and a frequency modulation module is used for carrying out frequency adjustment on the radio frequency signal, so that the effect of better sound effect is achieved. Meanwhile, a power amplifier module is arranged to amplify the power of the audio signal, so that the effect of large audio playing sound is achieved. An overvoltage protectionmodule is arranged to carry out overvoltage protection on the audio playing device, even a charging module is arranged to supply power to the audio playing device, and a power bank module is arrangedto store the electric energy and charge the external equipment. The audio playing device has the advantages that the audio playing device not only can be used as the audio equipment, but also has thefunction of a power bank, the external equipment can be charged at anytime and anywhere, the function of the audio playing device is optimized, and the user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of electronic circuits, and in particular relates to an audio playback device with a power bank function. Background technique [0002] In recent years, with the rapid development of electronic technology, the use of audio equipment has become more and more extensive. Miniaturized audio devices, such as portable speakers and car speakers, only have the function of audio playback, and their functions are single, which cannot meet the needs of users to a certain extent, resulting in reduced user experience. [0003] Therefore, the existing audio equipment only has an audio playback function, and its function is single, which cannot meet the needs of users to a certain extent, resulting in the problem of reducing user experience. Contents of the invention [0004] The purpose of the present invention is to provide an audio playback device with a built-in power bank function, aiming to solve the problem that ...
