Description

A charger with audio and video playing function

technical field

The utility model relates to the field of electric appliances, in particular to a charger with video and audio playing function. the

Background technique

With the diversification of various digital products and the characteristics of easy portability, the number of digital products that people carry with them is gradually increasing, especially digital products such as mobile phones, digital cameras, e-readers, MP3, MP4, MP5, etc. In order to facilitate people Portable, these electronic products are getting thinner and thinner, and the functions are becoming more and more. At the same time, the battery becomes thinner with the continuous reduction of the product, and the battery capacity is also reduced accordingly, and the effective use time for people becomes longer. Short, can not meet people's needs, therefore, when people go out on a trip or business trip, in order to ensure that they can charge digital products in time, people must carry chargers for various digital products, which is very inconvenient, and the function is single, only It can supplement electricity for digital products, so there are defects in the prior art and need to be improved. the

Utility model content

The technical problem to be solved by the utility model is to provide a charger with a simple structure, convenient to carry, equipped with an audio-visual playback function, and safe to use. the

In order to solve the above-mentioned technical problems, the utility model is realized through the following proposals: a charger with audio-visual playback function, including a power connection port, a conversion circuit, a high-frequency conversion circuit, a power rectification module, an output port, and an audio-visual playback device, The conversion circuit is connected to the power connection port, and the power connection port is connected to an external power supply for providing an input voltage for the input part, the conversion circuit is connected to the high frequency conversion circuit, and the high frequency The conversion circuit is connected to the power rectification module, the power rectification module is connected to the output port, and the audio-visual playback device is connected to the power connection port. The data memory is connected, the data memory is provided with a memory port, and the audio-visual playback circuit is provided with an audio output interface;

The video and audio playback circuit is provided with a switch button. the

Compared with the prior art, the beneficial effect is that the input voltage of the power supply connection port is converted into a voltage suitable for the high-frequency conversion circuit through the conversion circuit, and the high-frequency conversion circuit converts the DC voltage output by the conversion circuit into a high-frequency alternating voltage , After rectifying the high-frequency alternating voltage output by the high-frequency conversion circuit through the power rectification module, it is then input into the connected electronic products, which is convenient to use; set the audio-visual playback function, and listen to music while replenishing power for digital products. The memory port is set to facilitate the connection of external devices, and the audio files are imported into the memory, which is convenient to use and has good economic benefits. the
