Description

Technical field: [0001] The invention relates to the technical field of electronic products, in particular to a 5.1-channel digital surround earphone. Background technique: [0002] With the continuous development of electronic technology, people have higher and higher requirements for sound effects, and audio devices have also developed from monophonic, stereophonic, Dolby Logic directional systems to digital surround types. After several years of development, DVD has become more and more popular because of its larger disc capacity, clearer images, more real audio functions, and ease of use. Usually, when watching movies with DVD, in order to achieve the best home theater effect, it is necessary to equip a 5.1-channel power amplifier, and then connect six matching speakers. It is extremely inconvenient, and at the same time, the volume is loud during use, which will affect other people's rest. Invention content: [0003] The object of the present invention is to provide...
