Description

Technical Field

[0001] This utility model relates to the field of audio glasses technology, and in particular to a recording audio glasses system. Background Technology

[0002] Currently, most mainstream audio glasses in the industry only have two microphones in one temple, with the microphone openings positioned vertically and the line connecting them pointing towards the wearer's mouth, serving to pick up sound and perform corresponding noise reduction. However, this microphone layout is not well adapted to far-field sound pickup, conference recording scenarios, and corresponding algorithms, and it also leads to faster battery drain on one temple, affecting the overall battery life of the device.

[0003] There is also a type of audio glasses with more than two microphones. It has one microphone in the nose pad for wearer identification, but this solution requires the front frame to be connected via a flexible circuit board, which makes it difficult to adapt to various front frames and is also more expensive, making it unsuitable for low-cost pure audio glasses.

[0004] Meanwhile, mainstream audio glasses in the industry currently lack built-in large-capacity independent storage chips, making it impossible to record without a mobile phone. This results in poor independence and excessive power consumption due to communication with the mobile phone for storage.

[0005] In view of the above, this utility model is hereby proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a recording-type audio glasses system that can record independently on one side or simultaneously on both sides, with good sound pickup effect, thereby meeting the recording needs of various scenarios, and can independently store recorded audio without relying on an external mobile phone, thus solving the above-mentioned technical problems existing in the prior art.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A recording-type audio glasses system, comprising:

[0009] The glasses body, the first independent sound pickup storage circuit, and the second independent sound pickup storage circuit; wherein,

[0010] The first independent sound pickup and storage circuit is disposed in the cavity of the first temple of the eyeglass body. The first independent sound pickup and storage circuit is composed of a circuit board and a first microphone, a second microphone, a low-power voice signal processor, a first main chip, a first storage chip, a bone conduction microphone and a first power supply disposed on the first circuit board. The first microphone and the second microphone are disposed at a distance from each other in the front end of the cavity of the first temple. The first microphone and the second microphone are disposed in the first temple with the corresponding first sound pickup hole and the second sound pickup hole on the first temple facing upward and downward respectively. The bone conduction microphone is disposed in the ear wearing area inside the first temple.

[0011] The second independent sound pickup and storage circuit is located in the cavity of the second temple of the eyeglass body. The second independent sound pickup and storage circuit is composed of a circuit board and a third microphone, a fourth microphone, an inertial sensor, a second main chip, a second storage chip, a wear detection sensor, and a second power supply, which are connected to the circuit board. The third microphone and the fourth microphone are arranged at a distance from each other at the front end of the cavity of the second temple. The corresponding third and fourth sound pickup holes of the third microphone and the fourth microphone on the second temple are both facing downwards. The wear detection sensor is located at the ear wearing area inside the second temple.

[0012] Compared with the prior art, the recording audio glasses system provided by this utility model has the following advantages:

[0013] By setting a first independent audio pickup and storage circuit and a second independent audio pickup and storage circuit in the temples on both sides of the glasses, it is possible to record independently on one side or simultaneously on both sides. This avoids the problem of excessive power consumption and limited application scenarios caused by single-side recording. Furthermore, since the circuits on both sides have independent storage chips, the recorded audio can be stored independently without relying on an external mobile phone. At the same time, due to the different arrangement of the dual microphone pickup holes on both sides, it can be adapted to different recording scenarios to achieve better audio pickup and recording effects.

[0069] Step 11: After waking up, the first main chip is put out of low-power mode;

[0070] Step 12: The first main chip, which is out of low power mode, determines whether the bone conduction microphone has a vibration signal. If yes, if a vibration signal is confirmed, proceed to step 13; otherwise, if no vibration signal is confirmed, proceed to step 16.

[0071] Step 13: The first main chip determines whether the first microphone and / or the second microphone receive an audio signal that meets the power requirements. If yes, it confirms that an audio signal that meets the power requirements has been received and proceeds to step 14.

[0073] Step 15: The first main chip processes the audio signal within the corresponding time period and ends the current detection.

[0074] Step 16: Return the second main chip to low-power mode and end the test.

The audio signals of the first microphone and / or the second microphone in the corresponding time domain are determined to be the wearer's voice signal and processed.

[0076] In summary, the smart glasses of this invention, by respectively arranging a first independent audio pickup and storage circuit and a second independent audio pickup and storage circuit within the temples on both sides, achieve independent recording and storage without relying on an external mobile phone, as each circuit has its own independent main chip, storage chip, and power supply. This avoids the problem of existing glasses with single-sided recording circuits, which suffer from rapid power consumption and inability to independently store recorded audio, requiring the assistance of an external mobile phone for storage. Furthermore, this application designs the microphone pickup holes on both sides of the circuit with different modes to meet the needs of various recording scenarios and achieve better recording results.

[0077] To more clearly demonstrate the technical solution and its effects provided by this utility model, the following detailed description of the solution provided by the embodiments of this utility model is given with reference to specific examples.

[0078] Example 1

[0079] like Figure 1 , Figure 2As shown, this embodiment provides a recording audio glasses system, which consists of a glasses body, a first independent sound pickup storage circuit, and a second independent sound pickup storage circuit. The temples on both sides of the glasses body are provided with an inner shell and an outer shell, which form a cavity. Each cavity contains a PCB, and each PCB is provided with at least two air-conducting microphones (mic means microphone). A main chip and an independent storage chip form a set of independent sound pickup storage circuits. The sound pickup holes of the two air-conducting microphones in one temple are arranged vertically on the upper and lower walls of the temple outer shell, and each sound pickup hole is connected to the air-conducting microphone through a sound guiding channel. The sound pickup holes of the two microphones in the other temple are both arranged downwards on the lower wall of the outer shell, and each sound pickup hole is connected to the corresponding air-conducting microphone through a sound guiding channel.

[0080] On the PCB inside the temple of the glasses, which is located above and below the pickup hole, there is a bone conduction mic located at the auricle of the temple. It forms a 3-mic array with the two air conduction mics. The bone conduction mic is fixed to the inner shell of the temple and is connected to the PCB through the FPC and connector inside the temple on that side.

[0081] An IMU sensor is installed on the PCB inside the temple on one side of the two air-conducting microphones, with both pickup holes facing downwards. A wear detection sensor is located at the earlobe of this side of the temple. The IMU sensor and the wear detection sensor together form a wear detection module. The wear detection sensor is fixedly connected to the inner shell of this side of the temple, and is connected to the FPC inside this side of the temple via a spring clip. The FPC is then connected to the PCB inside this side of the temple via a connector.

[0082] A physical button for starting recording is located on one side of the temple of the two air-conducting microphones, with both pickup holes facing downwards. This allows users to quickly initiate recording and uses the main chip on this side to detect different scenarios and select the appropriate microphone for each scenario. The inside of the physical button contacts a spring, which is connected to the PCB inside the temple of that side via an FPC connector.

[0083] See Figure 3After the user presses the physical button, the second main chip uses the IMU sensor and wear detection sensor to determine whether the user is wearing the device. If the user is not wearing the device, all four microphones are used for sound pickup. No noise reduction algorithm is applied, and the longest recording time is stored in the corresponding memory chip via the corresponding main chip. Later, the signals from the four microphones can be synthesized and noise-reduced using a large model algorithm via a mobile app. If the user is wearing the device, the chip determines whether they are in a call. If they are in a call, the two microphones arranged vertically above and below the microphone hole are used for sound pickup and noise reduction. The sound pickup and noise reduction algorithm mainly utilizes the two microphones for sound pickup. The system uses a beamforming algorithm pointing towards the wearer to generate a single-channel sound enhancement signal, which is then combined with the phone call audio and stored in storage. If the user is not in a call, the system checks if the bone conduction microphone is vibrating. If it is, it uses two microphones arranged vertically to pick up sound and applies a noise reduction algorithm based on the wearer's voice, then records and stores the audio. If the bone conduction microphone is not vibrating, the system uses two microphones arranged on one side to pick up sound. The noise reduction algorithm mainly utilizes a beamforming algorithm pointing forward from the single-sided microphone to generate a single-channel sound enhancement signal, which is then combined with the phone call audio and stored in storage.

[0084] Different microphone layouts with different microphone orientations, combined with different noise reduction algorithms, are mainly achieved by designing the angle between the sound source and the microphone array axis, as well as the distance between the microphones.

[0085] Simplified suppression function in a dual-mic system Where d is the distance between the microphones, f is the frequency of the sound signal, and c is the speed of light. For the target direction, For actual direction; in target direction = To minimize suppression, the degree of suppression in other directions depends on the frequency and microphone spacing.

[0086] The two air-conducting microphones positioned above and below the pickup holes are also equipped with a low-power voice DSP chip on the PCB inside one side of the temple. The 3-mic array, the low-power voice DSP chip, and the wearer detection module together form a low-power wearer voice detection system.

[0087] The bone conduction microphone located on the PCB can serve as an effective supplement to the bone conduction microphone located on the auricle. The PCB is located at the front of the temple, and the wearer's voice vibration can be transmitted to the frame and the front of the temple through the nose pad, thereby stimulating the vibration of the bone conduction microphone on the PCB and enabling the wearer's voice to be judged.

[0088] See Figure 4When the glasses are worn, the first main chip is in a low-power state, and the low-power voice DSP works normally. After the low-power voice DSP receives the voice wake-up word, it activates the first main chip and first checks whether the bone conduction mic is vibrating. If not, the first main chip returns to the low-power mode. If it is, it continues to check whether the air conduction mic is continuously receiving an audio signal and whether the bone conduction mic is vibrating within the same time period. If both are present, it is considered as audio input from the wearer; otherwise, it returns to the low-power mode.

[0089] Within the same time period as the air conduction mic audio signal, if the bone conduction mic vibration spectrum range is 100-1000Hz and the SNR is greater than 20dB, it indicates that the wearer has a vibration signal. The corresponding air conduction mic audio signal in the time domain is then processed as the wearer's signal.
