Problems solved by technology

These high-end digital products give people a good enjoyment in terms of visual functions, but they are lacking in auditory functions. At present, general tablet computers or smart phones only have one speaker or two speakers, that is to say, two speakers It is fixedly responsible for outputting the left or right channel. Under normal posture, the output of the left and right channels can achieve good music effects, but once the operator rotates the digital product at a certain angle, the output of the left and right channels will The sound of the ear is not the best position for the human ear, so the sound effect will be reduced

Abstract

A sound channel automatic switching device comprises a three-dimensional sensor, a processor, a channel switching module and an audio signal source. The three-dimensional sensor acquires the current posture of the sound channel automatic switching device, and transmits a signal to the processor; the processor controls the channel switching module to distribute the left sound channel and the right sound channel of the audio signal source to four different channels of loudspeakers. The sound channel automatic switching device provided by the invention can adapt to the switching of the posture and can automatically switch sound channel output, the left loudspeakers output the left sound channel, the right loudspeakers output the right sound channel, a user still feels a sound effect that the left loudspeakers output a left sound channel sound, and the right loudspeakers output a right sound channel sound, so that the consistency of the sound direction is ensured even if a device rotates in any direction, the live effect of music / movies can be perfectly displayed at any time and in any direction, and the user' delight of the experience is increased.

Description

technical field [0001] The invention relates to audio equipment, especially a device capable of automatically switching sound channel output in response to posture changes. Background technique [0002] With the advancement of technology, electronic digital products continue to introduce new ones. A new generation of electronic digital products, smart handheld devices, such as smart phones, tablet computers and other portable devices with automatic image rotation functions, are emerging rapidly. Smart handheld devices are characterized by their powerful entertainment functions. It is deeply loved by young people. At present, tablets and high-end smartphones will integrate a G-sensor (Gravity-sensor), which is a gravity sensor, which can sense changes in acceleration force, which is the force that an object acts on an object during acceleration. , such as shaking, falling, rising, falling and other moving changes can be converted into electrical signals by the G-sensor, and ...
