Embodiment Construction

[0029] Although the existing data synchronization function can protect copyright, it is also a real inconvenience for people.

[0030] On the contrary, the embodiment of the present invention provides an interface device, which can enhance the convenience of listening to music content. Generally speaking, in order to reduce the size of the notebook computer, the notebook computer is not equipped with an audio input interface, but almost all notebook computers are equipped with a Universal Serial Bus (USB) interface. Based on copyright protection, the music files in the media player device will be restricted and cannot be copied and output to other electronic devices with the data synchronization function. Therefore, the media player cannot transmit music files to the notebook computer through the USB interface of the notebook computer.

[0031] It is worth noting that the media playback device can output analog audio signals based on music files. However, the USB interface c...

Abstract

The invention discloses an interface device, comprising a connection interface and a codec. The connection interface is used for being connected to a media player. The media player is capable of outputting analogue audio electric signal to the connection interface according to an audio file. The codec is coupled to the connection interface and used for converting the analogue audio electric signal into digital audio electric signal. Therefore, the convenience for listening to music content is improved.

Description

technical field [0001] The invention relates to an interface device, in particular to an interface device which can be connected between a media playing device and an electronic device. Background technique [0002] Recently, handheld devices with music playing function are becoming more and more common. The above-mentioned handheld device greatly improves the convenience for people to listen to music, so that people can listen to music anytime and anywhere. [0003] As the awareness of copyright protection increases, people are becoming more and more accepting of concepts such as user fees and music licensing. For example, I-Pod players, I-Phone mobile phones, etc. are all equipped with a data synchronization (Data synchronization) function with a copyright protection function. More specifically, based on copyright protection, the music files in the media player device will be restricted and cannot be copied and output to other electronic devices through the data synchron...
