Description

Technical Field

[0001] The present invention relates to the technical field of in-vehicle seat dynamics, specifically a seat dynamics control system. Background Art

[0002] In-vehicle music refers to music played in a car. However, due to the influence of the in-vehicle environment, some measures need to be taken to improve the sound quality. Selecting high-quality music files, using the noise reduction function of in-vehicle audio equipment, listening to music in a relatively quiet environment, and reasonably adjusting the volume and sound quality are all effective methods to improve the quality of in-vehicle music. This allows the driver to enjoy high-quality music while driving. An automotive audio shaker is an audio vibrator mainly used in the field of automotive entertainment to increase the audio vibration somatosensory entertainment configuration in a car.

[0003] For example, in the Chinese patent publication No. CN115675308A, "An In-vehicle Audio Playing Method, Player, In-vehicle System and Storage Medium", the player includes: an in-vehicle power amplifier circuit, a control unit, a first codec, a second decoder, a path switching switch, and an AUX interface. After receiving audio data through the AUX interface, the control unit determines the corresponding working mode according to the user's operation information, and based on the working mode, controls the path switching switch to adjust to the corresponding working mode, and selects the first codec or the second decoder to process and output the audio according to different working modes.

[0004] With the development of technology, existing in-vehicle playback devices have more functions. They can connect to a smartphone via the Internet and Bluetooth to play audio files in the phone, or play network audio in a car through an independent device. However, when existing in-vehicle audio is played, the music experience brought to the driver still cannot reach a very good effect. When the driver increases the audio playback volume during driving to enhance the music experience, it will affect the driving safety of the driver. The prior art has not perfectly combined in-vehicle audio with the car seat, resulting in the driver lacking a sense of experience of the music rhythm.

The microprocessor module 22 can extract the bass audio and rhythm of the audio signal using the microprocessor and transmit the extracted bass audio to the sound vibration control unit 3.

[0043] Embodiment 2

[0044] Please refer to Figure 2 and Figure 3 In this embodiment, an implementation method is proposed for a seat dynamic control system. The automotive sound shock includes an upper cover 4, a bottom shell 5, a voice coil 6, a shrapnel 7, a boron magnet 8, a U-shaped iron 9, and a pole piece 10. The bottom of the voice coil 6 is adhesively bonded to the inner wall of the bottom shell 5. The top of the U-shaped iron 9 is adhesively bonded to the bottom of the pole piece 10, and the bottom of the U-shaped iron 9 is adhesively bonded to the bottom of the boron magnet 8. The outer wall of the pole piece 10 is welded to the inner edge of the shrapnel 7. The bottom of the shrapnel 7 is fixedly connected to the top of the bottom shell 5 by bolts. Both the upper cover 4 and the bottom shell 5 are formed by die-casting aluminum, and the shrapnel 7 is made of manganese steel.

[0045] In this embodiment, the automotive sound shock is small in size and thin in thickness. The automotive sound shock is installed inside the bottom sponge of the vehicle seat cushion. The automotive sound shock is composed of an upper cover 4, a bottom shell 5, a voice coil 6, a shrapnel 7, a boron magnet 8, a U-shaped iron 9, and a pole piece 10. The upper cover 4 and the bottom shell 5 are formed by die-casting aluminum. The shrapnel 7 is made of 65 manganese steel. The voice coil 6 is fixed to the bottom shell 5 with AB glue. The pole piece 10, the U-shaped iron 9, and the boron magnet 8 are adhesively bonded together, and then welded to the shrapnel 7 with a cold welder. Finally, the shrapnel 7 is fixed to the bottom shell 5 with bolts. At the same time, there is a lead wire on the voice coil 6 that is led out through a notch on one side (facilitating the introduction of current). When the microprocessor module 22 uses a microprocessor to extract the bass frequency and rhythm of the audio signal and transmits the extracted bass frequency to the sound shock control unit 3, the sound shock control unit 3 amplifies the extracted mid-low frequency current and passes it through the lead wire into the voice coil 6. A magnetic field will be generated around the current-carrying voice coil 6. The pole piece 10 moves under the action of the magnetic field. Since the direction of the current changes continuously, the direction of the magnetic field magnetic induction lines also changes continuously. The pole piece 10 moves reciprocally under the action of the electromagnetic force. The shrapnel 7 has a certain elasticity and yield strength. The elastic force and the electromagnetic force received by the pole piece 10 are always a pair of reaction forces. The pole piece 10 moves reciprocally under the action of the elastic force and the electromagnetic force to generate mechanical vibrations, and the frequency, amplitude of the mechanical vibration are positively correlated with the frequency and current of the audio.

[0046] Working principle of the present invention: The seat dynamic control system of the present invention is composed of an in-vehicle playback unit 1, an audio control unit 2, and a sound shock control unit 3. When the driver needs to play in-vehicle audio, the network recognition module 12 can recognize the network status when the in-vehicle audio playback system is started, and intelligently select the network type according to the current network situation to improve the efficiency and quality of audio transmission, reduce the phenomenon of audio lag during transmission, and the signal processing module 15 further reduces the influence of noise on the audio signal during transmission by denoising and amplifying the audio, ensuring the sound quality of the audio played in the vehicle;

[0047] By adding an audio control unit 2 and a sound vibration control unit 3 (automobile sound vibration), when in-vehicle audio is played, after the signal receiving module 13 receives the original audio signal on the media server connected by the media connection module 11, the original audio signal is transmitted to the audio control unit 2. At this time, the preprocessing module 21 receives the original audio signal transmitted by the signal receiving module 13, and performs processing such as interference isolation, amplification, filtering, and analog-to-digital conversion on the original audio signal, so that the original audio signal becomes a signal that can be recognized and processed by a microprocessor (the microprocessor module 22 controls the microprocessor). The microprocessor module 22 can use the microprocessor to extract the bass audio and rhythm of the audio signal, and transmit the extracted bass audio to the sound vibration control unit 3;

[0048] After the microprocessor module 22 uses the microprocessor to extract the bass audio and rhythm of the audio signal and transmits the extracted bass audio to the sound vibration control unit 3, the sound vibration control unit 3 amplifies the extracted mid-low audio current and then passes it through a lead wire into the voice coil 6. A magnetic field will be generated around the current-carrying voice coil 6. The pole piece 10 moves under the action of the magnetic field. Since the direction of the current changes continuously, the direction of the magnetic field magnetic induction line also changes continuously. The pole piece 10 moves reciprocally under the action of the electromagnetic force. The shrapnel 7 has a certain elastic force and yield strength. The elastic force and electromagnetic force received by the pole piece 10 are always a pair of reaction forces. The pole piece 10 moves reciprocally under the action of the elastic force and electromagnetic force to generate mechanical vibration, and the frequency, amplitude of the mechanical vibration are positively correlated with the frequency and current of the audio;

[0049] In the present invention, when in-vehicle audio is played, the bass audio in the in-vehicle playback unit 1 can be extracted through the audio control unit 2, amplified by the signal and then transmitted to the sound vibration control unit 3. Then, the sound vibration control unit 3 controls the automobile sound vibration to generate mechanical vibration. The sound vibration control unit 3 receives the mid-low audio current and passes it through a lead wire into the automobile sound vibration, thereby generating mechanical vibration, increasing the driver's experience of the music rhythm in the automobile audio vibration sense. The driver can personally experience the vibration identical to the music rhythm while listening to music on the seat. By perfectly combining the in-vehicle audio with the automobile seat, the driver's feeling of the music rhythm is enhanced, the pleasure brought by the music is improved, and at the same time, the potential safety hazard of the driver during the driving process is reduced.
