Portable audio and video output device with multi-channel output function

This author is about a portable audio and video output device with multi-channel output function, especially for a front channel speaker built-in with portable audio and video output device without external audio device or amplifier. The sound output unit achieves the efficacy of a multi-channel speaker, and is non-spatial and maneuverable in use, and has a comfortable and non-covering ear when used, and is simple, convenient, and low-cost in setting. Portable audio and video output device with channel output function.

Nowadays, due to the improvement of the quality of life, people use multi-channel methods such as 5.1 channel or 7.1 channel when watching movies or playing video games. However, today's portable audio and video output devices only have a single speaker or two speakers, so users can only listen to stereo sound or two-channel sound and can not listen to multi-channel sound. To this end, the manufacturer has developed an external sound device to allow users to listen to multi-channel sound. However, since the external sound device and its external speakers take up space and are difficult to install, users can only listen to multi-channel sound. In a specific location, you can't listen to multi-channel sound anytime, anywhere, and users can increase the cost of listening when they purchase external audio devices and their external speakers. In addition, some manufacturers add speakers to portable audio and video output devices to make them portable. The audio and video output device can generate multi-channel sound effects. However, since the speakers that generate multi-channel sound effects are all disposed on the same body and are close to each other, they cannot produce true multi-channel sound effects. Moreover, other manufacturers are at the head. A plurality of single speakers are respectively placed in the left ear cup and the right ear cover of the wearing earphone to generate multi-channel sound effects. However, since the monomers for generating multi-channel sound effects are disposed in the left ear cover and the right ear cover, each other The distance is similar, so it can't produce real multi-channel sound. Moreover, when the user uses the headset, the earmuff will cover the user's ear and will User-generated hot pain and discomfort (especially those who wear glasses).
