During implementation, the multi-channel data processing module 103 may be implemented based on a multi-channel sound card apparatus. Correspondingly, the pending signal output by the signal processing module 102 is required to be a signal that may be identified by the multi-channel sound card apparatus, for example, an audio and video data stream.

For ease of understanding, the following explains the use process of the multi-channel vehicle-mounted seat vibration feedback system 100 for different automobile interaction scenarios.
First, in a navigation scenario, an effect generated by the multi-channel vehicle-mounted seat vibration feedback system 100 may be to transmit navigation, driving and other information to a driver through seat vibration.

In the above usage scenarios, the multi-channel vehicle-mounted seat vibration feedback system 100 of the present disclosure may assist the user in performing safety driving or danger warning through tactile sensation in the case of visual and auditory deficiency, enhance the distinguishing of information prompt, reduce the learning cost of the user, and thus improving road driving safety.
Second, an effect generated by the multi-channel vehicle-mounted seat vibration feedback system 100 may be to transmit multimedia information to a driver through seat vibration and sound:
In the case of playing music in an automobile, the interaction signal is the audio data of the music. Different audio data may be processed by the signal processing module 102, and the specific preset machine learning algorithm is called to obtain the audio data having different features (such as voice and different musical instruments). After processing the audio data according to certain rules, the multi-channel vibration and audio signals having different music features in different signal channels are obtained by the multi-channel data processing module 103. The different motors in the vehicle-mounted seat may work independently after receiving the driving signals, thereby achieving the three-dimensional tactile effect of distinguishing content. In addition, it plays synchronously with music to improve the three-dimensional sense, rhythm and richness of music.
In the scenario of playing audio and video in an automobile, the interaction signal is video stream data of the audio and video. Because the video stream includes both audio and video, the video stream data may be processed by the signal processing module 102 by calling a specific preset machine learning algorithm, so as to obtain the pending signals including different sound characteristics and vibration characteristics. Then, the multi-channel signals including different vibration data and audio data in different signal channels are obtained by the multi-channel data processing module 103. The different vibration motors and speakers in the vehicle-mounted seat may work independently after receiving the driving signals, thereby achieving the stereoscopic vibration and surrounded stereo sounding effects of distinguishing content;
In the above usage scenarios, the signal processing module 102 performs processing based on the preset machine learning algorithm, different events such as automobile roar and object collision are identified from audio and video data. For different events identified, event features such as sound spectrum and time domain envelope may be analyzed in real time, and corresponding vibration signals may be generated according to the preset tactile generation strategy in the algorithm. The vibration signals corresponding to the events may also be retrieved from the effect library according to the preset strategy, and the vibration signals may be processed according to the event characteristics.
In the scenario of playing games in an automobile, the interaction signal is game data. The difference between game data and audio is that in addition to containing all in-game audio and video data, it may also contain a variety of signals input through the controller. Similarly, these data may be processed by the signal processing module 102, a specific preset tactile generation strategy or machine learning algorithm is called to obtain the pending signals including different sound features and vibration features. Then, the multi-channel signals including different vibration data and audio data in different signal channels are obtained by the multi-channel data processing module 103. Different vibration motors and speakers in the vehicle-mounted seat may work independently after receiving the driving signals, which may achieve a more stunning game experience.
In the above usage scenarios, the signal processing module 102 dynamically adjusts the vibration signals in real time according to the interaction parameters in the game, and the control dimension of the vibration signals includes but is not limited to: intensity, frequency, envelope curve, etc.
In addition, in embodiments of the present disclosure, each of the multi-channel data corresponds to at least one of the feedback output channels, and each of the tactile feedback output channels corresponds to an individual vibration motor or speaker of the automobile seat, so that a vibration signal correspondingly generated by each interaction signal may be divided into a plurality of vibration files according to actual needs. A vibration signal corresponding to each interaction event may be allocated to one or more vibration motors, thereby achieving a better vibration or sounding effect according to characteristics of different vehicle-mounted seats.
