Description

Technical Field

[0001] This utility model relates to the field of high-fidelity decoder technology, specifically to a USB high-fidelity decoder with a vibration unit. Background Technology

[0002] Typical USB-C external sound cards bridge the USB host and headphones (or headsets) via a USB codec (audio codec). This type of USB audio codec integrates an analog-to-digital converter (AD) for the microphone and a digital-to-analog converter (DA) for the headphones, simultaneously converting between USB data streams and analog signals. Existing high-fidelity decoders like the HiFi dongle and USB-C external sound cards follow traditional design concepts, limited by chip manufacturers' chip technology. Externally, improvements to the headphones are needed to enhance the overall auditory performance, allowing users to experience the audio through sound. However, blindly increasing the target frequency / band amplitude using traditional methods leads to sound distortion, unpleasant listening, and a poor experience; in severe cases, it can even damage hearing. This approach fails to fundamentally address the ever-evolving functional requirements and cannot provide customers with a completely new entertainment experience. Therefore, this paper proposes a USB high-fidelity decoder with a vibration unit to address these issues. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-2As shown, this utility model provides a USB high-fidelity decoder with a vibration unit, including an integrated board 1. The integrated board 1 is provided with a USB component 2, a system control component 3, a Bluetooth component 4, a first motor component 5, a first vibration drive component 6, an audio signal processor component 7, a speaker component 8, a second motor component 9, a second vibration drive component 10, an earphone component 11, and a high-fidelity digital-to-analog converter component 12. The system control component 3 is connected to the USB component 2, Bluetooth component 4, first vibration drive component 6, audio signal processor component 7, second vibration drive component 10, and high-fidelity digital-to-analog converter component 12. The USB component 2 and audio signal processor component 7 are both connected to the high-fidelity digital-to-analog converter component 12, and the high-fidelity digital-to-analog converter component 12 is connected to the earphone component 11. The USB component 2 and Bluetooth component 4 are respectively connected to the audio signal processor component 7, and the audio signal processor component 7 is connected to the first vibration drive component 6, the second vibration drive component 10, and the speaker component 8. At the same time, the first vibration drive component 6 and the second vibration drive component 10 are respectively connected to the first motor component 5 and the second motor component 9.

[0021] In this embodiment, the high-fidelity digital-to-analog converter assembly 12 includes a high-fidelity operational amplifier driver unit 1201 and a high-fidelity digital-to-analog converter HiFi DAC unit 1202, and both the high-fidelity operational amplifier driver unit 1201 and the high-fidelity digital-to-analog converter HiFi DAC unit 1202 are connected to the system control assembly 3.

[0022] Furthermore, USB component 2 features a digital audio source input.

[0023] After the USB component 2 receives the input from the digital audio source transmitted via the external type-C data cable, the system control component 3 synchronously controls the downlink, while the Bluetooth component 4 also performs uplink / downlink transmission through the output / input of the digital audio source.

[0024] In this embodiment, the high-fidelity digital-to-analog converter 12 includes a high-fidelity operational amplifier driver 1201 and a high-fidelity digital-to-analog converter HiFi DAC 1202, and the USB component 2 and the audio signal processor component 7 are connected to the high-fidelity digital-to-analog converter 12 via digital paths.

[0025] Furthermore, a digital path is provided between the USB component 2, the Bluetooth component 4, and the audio signal processor component 7.

[0026] After the USB component 2 and Bluetooth component 4 transmit via a digital path, the digital sound / music signal is processed by the audio signal processor component 7 and then sent to the speaker component 8, the first vibration drive component 6, and the second vibration drive component 10. At the same time, the first vibration drive component 6 and the second vibration drive component 10 drive the first motor component 5 and the second motor component 9 to vibrate, and the speaker component 8 makes the speaker produce sound.

[0027] After the USB component 2 is directly connected via a digital path and the Bluetooth component 4 is digitally or analog connected to the high-fidelity digital-to-analog converter component 12 via the audio signal processor component 7, the digital audio / music signal is simultaneously decoded by the high-fidelity digital-to-analog converter component 12 and sent to the headphone component 11 to make the headphones produce sound.

[0028] Furthermore, the speaker assembly 8 is connected to the speaker.

[0029] Furthermore, the headphone assembly 11 is connected to the headphones.

[0030] Furthermore, the first motor assembly 5 and the second motor assembly 9 are respectively connected to the motor.

[0031] Working principle:

[0032] The USB component 2, system control component 3, Bluetooth component 4, first motor component 5, first vibration drive component 6, audio signal processor component 7, speaker component 8, second motor component 9, second vibration drive component 10, headphone component 11, and high-fidelity digital-to-analog converter component 12 are integrated into a single integrated board 1. This integrated board 1 forms a complete module, which can be attached to the surface of objects such as mobile phones or embedded in a phone case. The digital audio (or analog audio) output from Bluetooth / USB is converted to analog by the DAC along the original path and then sent to the headphone component 11 for amplification before being played out by the headphones. At the same time, the digital audio (or analog audio) output from Bluetooth / USB or the DAC output is sent to the audio signal processor component 7 through another path (which performs dynamic voltage control, filtering, multi-order bandpass, audio signal feature analysis, etc. on the audio signal), and then sent to the first vibration drive component 6 and the second vibration drive component 10, which are then connected to the first motor component 5 and the second motor component 9 respectively to drive the motors to vibrate. Meanwhile, the audio signal processor component 7 is directly connected to the speaker component 8 to drive the speaker to produce sound.

[0033] In the headphone mode, the USB sound card mode is as follows: Powered by a Type-C cable, digital audio / music is transmitted to the USB component 2 via the Type-C data cable. The USB component 2 then sends the signal to the high-fidelity digital-to-analog converter 12 via a digital path. The analog audio / music decoded by the high-fidelity digital-to-analog converter 12 is transmitted to the headphone component 11 and output through the high-fidelity headphone channel. Simultaneously, the analog audio / music signal output from the USB component 2 via the digital path or the high-fidelity digital-to-analog converter 12 is transmitted to the audio signal processor component 7 for processing, and then sent to the first vibration drive component 6 and the second vibration drive component 10. Finally, the first vibration drive component 6 and the second vibration drive component 10 transmit the signal to the first motor component 5 and the second motor component 9 respectively, driving the motors to vibrate. This vibration rhythm is synchronized with the audio / music heard through the headphones, while also providing uplink / downlink call functionality.

[0034] In Bluetooth mode, the following steps are taken: The device is powered by a Type-C cable. Digital audio / music is transmitted to the USB component 2 via the Type-C data cable. The analog audio / music signal, decoded by the digital path or high-fidelity digital-to-analog converter 12, is then transmitted to the Bluetooth component 4 via the audio signal processor 7. The Bluetooth component 4 then transcodes the audio / music to its internal Bluetooth chip, which transmits it to Bluetooth receiving devices such as TWS. Simultaneously, the audio signal processor 7 also sends the audio / music to the corresponding processing module within its own unit. After processing, the signal is sent to the first vibration drive component 6 and the second vibration drive component 10. Finally, the first and second vibration drive components 6 and 10 transmit the signal to the first motor component 5 and the second motor component 9, respectively, to drive the motors to vibrate. This vibration rhythm is synchronized with the audio / music heard by the Bluetooth receiving device, and Bluetooth uplink / downlink calling functionality is also provided.

[0035] In the no-headphone, no-Bluetooth receiver mode, USB sound card mode and Bluetooth mode are the same: Type-C power supply, digital sound / music is transmitted to USB component 2 through Type-C data cable, and then the analog sound / music signal decoded and output by the digital path or high-fidelity digital-to-analog converter component 12 through USB component 2 is processed by audio signal processor component 7 and then sent to the first vibration drive component 6 and the second vibration drive component 10. Finally, the first vibration drive component 6 and the second vibration drive component 10 transmit the signal to the first motor component 5 and the second motor component 9 respectively to drive the motor to vibrate. At the same time, the audio signal processor component 7 drives the speaker component 8 to make the speaker play sound. The software automatically switches so that the system plays sound / music through the speaker while the motor generates a specific vibration, and the vibration rhythm of the motor and the sound / music output of the speaker are synchronized.

[0036] Furthermore, the input signal source can be from digital / analog audio sources such as Bluetooth / WiFi / USB or analog audio output from a DAC. The digital or analog audio is sent to the audio signal processor component 7 of this invention. This component 7 first performs dynamic voltage control on the input digital or analog audio, adjusting the input signal of different amplitudes to an ideal / desired amplitude. Filters and multi-order bandpass filters amplify, limit, or attenuate the input signal according to different frequencies. Audio signal feature analysis filters and processes the input signal based on the defined amplitude and frequency. After the above processing... The signal is amplified by the drive chip in the first vibration drive component 6 and the second vibration drive component 10, and finally the required signal is obtained to drive the motor to work. At the same time, after being controlled by the USB component 2 or the system control component 3, the audio signal is output as sound waves through the headphones / speakers after passing through different paths. Simultaneously, the same source audio signal is output by the first motor component 5 and the second motor component 9 to drive the motor to vibrate, making the sound tangible. Users can simultaneously feel the melody / music and the vibration rhythm brought by the melody / music from two different dimensions of hearing and touch, which improves the overall entertainment effect of the integrated board 1.
