However, most wearable devices on the market currently focus on visual and auditory perception, with limited support for haptic feedback, particularly lacking effective integrated design in low-frequency vibration feedback and 3D audio collaboration. Existing vest-style haptic feedback devices often suffer from problems such as uncomfortable wear, insufficient vibration feedback intensity, poor audio output, limited connectivity, and insufficient battery life, making it difficult to meet the demands of prolonged, high-intensity immersive use. Furthermore, most systems lack coordinated management of multimodal signals, making it difficult to achieve synchronization and interactivity between audio and haptic feedback. Therefore, it is essential to design a haptic feedback-based wearable vest system that enhances the user's immersive experience in virtual environments. Summary of the Invention

Haptic feedback module: includes two automotive-grade linear resonant drivers symmetrically embedded on both sides of the spine in the back, with an operating frequency range of 5Hz to 150Hz. It supports the generation of corresponding haptic feedback signals based on the extraction of low-frequency components from audio signals, and outputs peak acceleration of not less than 1.2G to achieve vibration response. Audio output module: Includes dual speaker units located on the shoulder and collarbone area, using neodymium magnet full-range speakers with directional sound field design, frequency response range of 100Hz to 20kHz, supports independent volume control and on / off switching, used to achieve immersive sound field output; Multimodal connectivity module: Includes Bluetooth 5.3 chipset, supports low latency aptX LL protocol, and features a 3.5mm audio output jack and a USB-C audio / charging combo port; Energy protection module: Includes a built-in 5000mAh lithium polymer battery and a fast charging circuit supporting the PD protocol.

[0005] Preferably, the shock-absorbing support frame in the vest structure module adopts a design that combines a lightweight aluminum alloy skeleton with multi-layer composite materials, taking into account both structural strength and wearing comfort. The back frame, through direct contact with the driver module and in conjunction with a highly shock-absorbing rubber pad, enables vibration signals to be efficiently transmitted to the densely nerve-rich area of ​​the user's back, improving the clarity of tactile response; The frame is covered with a high-resilience, breathable mesh fabric and is stitched together with the main vest, providing excellent heat dissipation and comfort for extended wear.

[0006] Preferably, in the haptic feedback module, the linear resonant driver receives and analyzes the externally input audio signal through a high-speed audio processing unit, and obtains the signal spectrum using a fast Fourier transform; The low-frequency components between 5Hz and 150Hz are extracted through a multi-stage bandpass filter and subjected to amplitude shaping and rhythm calibration to form a set of vibration driving parameters corresponding to the dynamic rhythm changes of the audio. The driving parameter set is sent to the resonant driver in real time through the control interface, so that it generates linear reciprocating motion according to the audio beat and intensity changes, generating perceptible synchronous vibration feedback.

[0007] Preferably, the audio output module uses full-range directional speaker units symmetrically arranged on the left and right shoulders, with their acoustic axes set to tilt forward by 10 to 15 degrees according to the structure of the human head, so as to form a stereo directional sound field concentrated around the user's auricle.

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] Example 1: Please refer to Figure 1 As shown in the embodiment of the present invention, a wearable vest system based on haptic feedback includes: Vest structural module: Includes an ergonomic vest body made of breathable elastic fabric, equipped with adjustable shoulder straps and side waist belts to fit users of different body types; its back has a support frame with a built-in rigid shock-absorbing layer to fix the core electronic module and provide a basis for wearing stability and vibration transmission.

[0015] The shock-absorbing support frame in the vest structure module adopts a design that combines a lightweight aluminum alloy skeleton with multi-layer composite materials, taking into account both structural strength and wearing comfort. The back frame, through direct contact with the driver module and in conjunction with a highly shock-absorbing rubber pad, enables vibration signals to be efficiently transmitted to the densely nerve-rich area of ​​the user's back, improving the clarity of tactile response; The frame is covered with a high-resilience, breathable mesh fabric and is stitched together with the main vest, providing excellent heat dissipation and comfort for extended wear.

[0016] Through the above structural design, the vibration signal can be transmitted more concentratedly to the densely nerve-rich area of ​​the back, enhancing the clarity and resolution of tactile feedback. At the same time, the frame structure has good heat dissipation performance and deformation adaptability, providing stable support and high comfort during long-term wear, effectively improving the user experience in an immersive interactive environment.

[0017] Haptic feedback module: Includes two automotive-grade linear resonant drivers symmetrically embedded on both sides of the spine in the back, with an operating frequency range of 5Hz to 150Hz. It supports the generation of corresponding haptic feedback signals based on the extraction of low-frequency components from audio signals, and outputs peak acceleration of not less than 1.2G to achieve vibration response.

[0018] In the haptic feedback module, the linear resonant driver receives and analyzes the externally input audio signal through the high-speed audio processing unit, and obtains the signal spectrum using fast Fourier transform. The low-frequency components between 5Hz and 150Hz are extracted through a multi-stage bandpass filter and subjected to amplitude shaping and rhythm calibration to form a set of vibration driving parameters corresponding to the dynamic rhythm changes of the audio. The driving parameter set is sent to the resonant driver in real time through the control interface, so that it generates linear reciprocating motion according to the audio beat and intensity changes, generating perceptible synchronous vibration feedback.

[0019] This structure enables the precise conversion of low-frequency dynamic changes in audio signals into perceptible vibration feedback, allowing the linear resonant driver to synchronize audio beats and intensity changes to generate physical tactile signals. This significantly enhances the user's immersion and interactive experience, making it particularly suitable for multi-sensory experiences in games, music, and other scenarios.

[0020] Audio output module: Includes dual speaker units located on the shoulder and collarbone area, using neodymium magnet full-range speakers with directional sound field design, frequency response range of 100Hz to 20kHz, supports independent volume control and on / off switching, used to achieve immersive sound field output.

[0021] The audio output module uses full-range directional speaker units symmetrically arranged on the left and right shoulders. Its sound axis is set to tilt forward 10 to 15 degrees according to the structure of the human head, so as to form a stereo directional sound field concentrated around the user's auricle. The speaker drive signal is output by the internal audio decoding module, which supports 96kHz / 24bit high-definition audio resolution to ensure high-fidelity playback. Through integrated volume control and sound field adjustment logic, independent volume settings and dynamic sound image positioning for the left and right channels are achieved, and users can adjust the degree of sound field focus according to ambient noise or content type.

[0022] It achieves highly directional stereo playback in the near-ear area, creating an immersive audio experience without covering the ears, while effectively reducing sound leakage and environmental interference; high-definition audio resolution enhances the reproduction of sound details, allowing users to obtain more realistic auditory feedback in immersive application scenarios; independent channel control and sound field focus adjustment functions improve the system's adaptability in complex environments and the level of personalized audio experience.

[0023] Multimodal connectivity module: Includes Bluetooth 5.3 chipset, supports low latency aptX LL protocol, and features a 3.5mm audio output jack and a USB-C audio / charging combo port.

[0024] The multimodal connection module supports the Bluetooth 5.3 standard and integrates a wireless communication chip that supports aptX Low Latency and AAC audio protocols, enabling audio latency control to be within 40ms. When the system connects to a mobile terminal or host device, it can automatically identify the game, movie or music scene according to the connection mode and switch to the corresponding low latency or high fidelity transmission mode. Meanwhile, the 3.5mm audio jack and USB-C combined port support wired audio input and simultaneous fast charging, adapting to the needs of various terminal devices.

[0025] By integrating a multimodal connectivity module supporting Bluetooth 5.3, aptX Low Latency, and AAC protocols, latency control as low as 40ms is achieved in wireless audio transmission, effectively avoiding perceptual misalignment between sound and haptic feedback, and significantly enhancing the immersive experience in gaming and movie scenarios. The connectivity system has the ability to intelligently identify different usage scenarios and automatically switch transmission modes, ensuring a flexible balance between low latency and high sound quality. It is also equipped with a 3.5mm and USB-C composite interface, supporting wired audio input and fast charging simultaneously, enhancing the device's compatibility and continuous use convenience in multi-platform and multi-purpose environments.

[0026] Energy protection module: Includes a built-in 5000mAh lithium polymer battery and a fast charging circuit supporting the PD protocol. It has an intelligent power consumption allocation strategy, which can achieve a total battery life of no less than 6 hours according to the usage mode, and is equipped with an overload protection circuit to prevent the driver and speaker from operating at overpower.

[0027] The energy protection module includes an integrated power detection sensor, a voltage regulation chip, and a thermal protection device. The system can dynamically adjust the output current distribution strategy based on the current battery power, speaker sound pressure level, and driver vibration intensity. During long-term high-load operation, the system prioritizes the power supply stability of the haptic feedback module through intelligent power consumption strategy, and appropriately reduces the speaker power output to extend battery life. When the remaining battery capacity is lower than the set threshold, it automatically enters energy-saving mode, reducing vibration frequency and sound field volume; It is also equipped with multiple overcurrent, overvoltage and overtemperature protection mechanisms.

[0028] By integrating power detection, current regulation, and thermal protection mechanisms, this energy protection module can achieve real-time monitoring and intelligent allocation of system energy consumption, effectively extending the overall equipment's battery life while ensuring vibration feedback response performance. Its dynamic power adjustment strategy can automatically reduce the energy consumption of non-critical modules under high load or low power conditions, ensuring the continuous operation of core functions. In addition, multiple overcurrent, overvoltage, and overtemperature protection mechanisms enhance the system's operational stability and safety in complex application environments, significantly reducing the risk of component damage caused by power anomalies.
