Description

MP3 player with host

technical field

The utility model relates to an MP3 player with a host end, especially the MP3 player which can be directly connected to an electronic device to replace sound data or output or input the stored data and the data stored in the electronic device without transparent Operate through the host, so that users can use the MP3 player more conveniently.

Background technique

With the development of science and technology, in order to make the transmission of information more convenient and fast, data storage devices have become an indispensable key. Early data storage devices such as: hard drives, because the structure of hard drives is equipped with motors and magnetic heads , so when the motor and magnetic head are running, the hard disk drive must be protected from vibrations, otherwise the hard drive may be damaged and cannot be used, and the hard drive is too large to be portable. Such problems make the hard drive unusable for digital Electronic products such as cameras, MP3 players, and PDA (PERSONALDIGITAL ASSISTANT) personal digital assistants; therefore, some related companies have developed flash memory and used control chips to combine flash memory to make a new storage device such as a flash drive, Memory card, and because flash memory has attractive characteristics such as low power consumption, non-volatility, shock resistance, and high storage density, and does not require components such as motors and magnetic heads, the size can be greatly reduced, and it can meet the needs of digital cameras, MP3 players and PDAs (PERSONAL DIGITAL ASSISTANT) personal digital assistant and other such electronic products.

However, this kind of storage device or electronic product made of flash memory must be connected to a host computer (such as a computer) before the data stored in it can be exchanged. When exchanging or saving data, the two must be connected to the host to execute. If there is no host device around the user, it will not be able to execute and cause inconvenience to the user. Therefore, some related companies have developed an OTG (ON-THE-GO) control chip, the biggest feature of this kind of OTG control chip is that it provides a way to connect two devices without using a computer or other host equipment to achieve point-to-point (POINT TO) POINT) link.

Furthermore, if the MP3 player made by flash memory needs to be connected to the host if it wants to add or change its stored songs, if the function of the OTG control chip can be set on the MP3 player made by flash memory In the Walkman, the MP3 Walkman can use other storage devices to change songs or transfer the stored data to the storage device without operating through the host, which will give users great convenience.

Therefore, how to solve the above-mentioned technical problems is the direction that relevant manufacturers engaged in this industry are eager to study and improve.
