Problems solved by technology

But this kind of shared earplugs is just a parallel connection between the mother earplugs and multiple sub-earplugs, without improving the player, the output of each earplug is the same and cannot be independent of each other
This still can't really realize that multiple people share an audio player

Embodiment Construction

[0015] Referring to FIG. 2 , it is a schematic diagram of an audio player with multiple independent audio outputs according to the present invention. The audio player 100 includes a plurality of audio output ports 9 (9A, 9B in FIG. 2 ), each audio output port 9 can be connected to a sound output device 10, and the sound output device 10 can be an earphone or a speaker. The audio player 100 plays multiple songs at the same time, and independently outputs audio signals of different songs through different audio output ports 9 at the same time. song. For example, the audio player 100 plays song A and song B simultaneously at a certain moment, and outputs the audio signal of song A through the audio output port 9A, and outputs the audio signal of song B through the audio output port 9B. The display unit 5 can cyclically display the current playing information.

[0016] The audio player 100 also includes a control panel 6, through the operation of the control panel 6 to generate ...

Abstract

The present invention provides an audio player with multi-channel independent audio outputs. The audio player comprises a plurality of audio output ports; each of the audio output ports is connected in sequence with an amplifier and a coder / decoder which are connected to a processing unit. When one of the audio output ports is selected for outputting audio frequency, the processing unit establishes a playing process to control the audio play of the selected audio output port. Able to simultaneously process at least two audio documents, the audio player with multi-channel independent audio outputs can be shared by a plurality of users. Every audio output port can output different audio signals.

Description

technical field [0001] The invention relates to an audio processing device, in particular to an audio player capable of multiple independent audio outputs. Background technique [0002] Recently, audio players such as MP3 are more and more subject to liking of people, and its quantity is constantly increasing. But the portable audio player of prior art can only be used by one person at the same time. Referring to FIG. 1 , it is a structural block diagram of an audio player in the prior art. The audio player includes: a processing unit 1, a communication interface 2, a storage device 3, a random access memory (RAM) 4, a display unit 5, a control panel 6, a codec 7, an amplifier 8 and An audio output port 9 . The user realizes the interconnection between the audio player and equipment such as a personal computer through the communication interface 2, and can download audio files to the storage device 3. The user sends instructions to the processing unit 1 through the contr...
