Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sound collection, and in particular to a sound collection device and AR glasses. BACKGROUND

[0002] In related technologies, an augmented reality (AR) glasses generally collects the sound of the environment through a microphone. However, when the microphone is applied in an environment where the sound intensity of the environmental sound is too large, such as when the sound intensity of the environmental sound exceeds 80 decibels, the sound distortion may easily occur. For example, the peak value of the sound signal collected by the microphone may be clipped. Clipping refers to the case that the sound signal exceeds the maximum level that can be processed by the AR glasses, resulting in that the top and bottom of the sound signal are "clipped", the originally smooth sinusoidal waveform becomes deformed, and a shape similar to a square wave is generated. The distorted sound signal will have obvious burr feeling, and the details and original tone of the sound will be lost, which may easily lead to poor sound collection effect of the microphone and cannot meet the sound collection demand of the user. CONTENT OF THE UTILITY MODEL

[0003] The main purpose of the present application is to provide a sound collection device and AR glasses, and to solve the technical problem of poor sound collection effect of the microphone on sound data with too large sound intensity.

[0004] In a first aspect, the present application provides a sound collection device, which comprises:

[0005] at least one microphone;

[0006] at least one loudspeaker, comprising a diaphragm, a coil and a magnetic piece; the coil moves relative to the magnetic piece when electrified, so that the diaphragm vibrates, and the coil moves relative to the magnetic piece when the diaphragm vibrates, so that the coil generates an induced electric signal;

[0007] a control module, connected with the microphone and the loudspeaker, used for acquiring the signal output by the microphone, and acquiring the induced electric signal generated by the loudspeaker when the sound intensity signal collected by the microphone corresponds to the sound intensity of the environmental sound greater than or equal to a preset sound intensity threshold, and converting the induced electric signal generated by the loudspeaker into first sound data.

[0008] In a second aspect, the present application provides AR glasses, comprising a hingedly connected frame and a temple, a first accommodating space is formed in the frame, a second accommodating space is formed in the temple, and the first accommodating space and / or the second accommodating space is used for accommodating the sound collection device as described above.

[0009] The application provides a sound collecting device and AR glasses. The sound collecting device comprises at least one microphone, at least one speaker, a control module, wherein the speaker comprises a diaphragm, a coil and a magnetic piece; the coil moves relative to the magnetic piece when the coil is powered to make the diaphragm vibrate, and the coil moves relative to the magnetic piece when the diaphragm vibrates to make the coil generate an induced electric signal; the control module is connected with the microphone and the speaker, and is used for acquiring the signal output by the microphone, and acquiring the induced electric signal generated by the speaker when the sound intensity signal collected by the microphone corresponds to the sound intensity of the environmental sound which is greater than or equal to a preset sound intensity threshold, and converting the induced electric signal generated by the speaker into first sound data.

[0010] The speaker moves relative to the magnetic piece when the coil is powered to make the diaphragm vibrate, so that the speaker can be used for playing corresponding sound data. The coil moves relative to the magnetic piece when the diaphragm vibrates to make the coil generate an induced electric signal. The induced electric signal can be used for determining the first sound data, so that the speaker can be used for collecting sound signals. The control module can determine that the signal output by the microphone is not suitable for being converted into second sound data when the sound intensity signal collected by the microphone corresponds to the sound intensity of the environmental sound which is greater than or equal to a preset sound intensity threshold. If the signal output by the microphone is converted into second sound data, the second sound data will have sound distortion, which leads to poor sound collecting effect of the microphone. When the sound intensity of the environmental sound is greater than or equal to the preset sound intensity threshold, the sound collecting effect of the speaker is better than that of the microphone. Therefore, the sound collecting device can convert the induced electric signal generated by the speaker into first sound data through the control module, so as to improve the sound collecting effect of the sound collecting device.

Obviously, the described embodiments are some of the embodiments of the present application, but not all of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of the present application.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0017] Some embodiments of the present application will be described in detail below with reference to the drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0018] Please refer to Figure 1 , Figure 1 A structural schematic diagram of a sound collecting device 100 provided by an embodiment of the present application.

[0019] As shown in Figure 1 , the sound collecting device 100 comprises at least one microphone 110, at least one speaker 120 and a control module 130.

[0020] The speaker 120 comprises a diaphragm 121, a coil 122 and a magnetic piece 123. The coil 122 moves relative to the magnetic piece 123 when energized, so that the diaphragm 121 vibrates, and the coil 122 moves relative to the magnetic piece 123 when the diaphragm 121 vibrates, so that the coil 122 generates an induced electric signal.

[0021] The control module 130 is connected with the microphone 110 and the speaker 120. The control module 130 is configured to acquire the signal output by the microphone 110, and acquire the induced electric signal generated by the speaker 120 when the sound intensity signal corresponding to the ambient sound collected by the microphone 110 is greater than or equal to a preset sound intensity threshold, and convert the induced electric signal generated by the speaker 120 into first sound data.

[0022] For example, the speaker 120 and the microphone 110 both have the ability to collect sound signals.

[0023] In the case that the environment where the sound collecting apparatus 100 is located has environmental sound, the environmental sound can cause the diaphragm 121 of the loudspeaker 120 to vibrate, and the diaphragm 121 can drive the coil 122 of the loudspeaker 120 to vibrate when vibrating. Correspondingly, the coil 122 can move relative to the magnetic part 123 of the loudspeaker 120 when vibrating, such as the coil 122 cutting the magnetic induction lines in the magnetic field provided by the magnetic part 123 when vibrating, thereby causing the coil 122 to generate an induced electric signal. The induced electric signal can be used as the sound signal collected by the loudspeaker 120 for subsequent determination of the first sound data.

[0024] In the case that the environment where the sound collecting apparatus 100 is located has environmental sound, the environmental sound can cause the diaphragm 121 of the loudspeaker 120 to vibrate, and the diaphragm 121 can drive the coil 122 of the loudspeaker 120 to vibrate when vibrating. Correspondingly, the coil 122 can move relative to the magnetic part 123 of the loudspeaker 120 when vibrating, such as the coil 122 cutting the magnetic induction lines in the magnetic field provided by the magnetic part 123 when vibrating, thereby causing the coil 122 to generate an induced electric signal. The induced electric signal can be used as the sound signal collected by the loudspeaker 120 for subsequent determination of the first sound data.

[0025] In some embodiments, the sound collecting apparatus 100 can include at least one loudspeaker 120. In the case that the sound collecting apparatus 100 includes multiple loudspeakers 120, the multiple loudspeakers 120 can be arranged at different positions of the sound collecting apparatus 100 to form a structure similar to an array of microphones 110. The sound collecting apparatus 100 can process and analyze the induced electric signals generated by the multiple loudspeakers 120 respectively to realize functions such as positioning of a sound source, enhancing a target sound, and suppressing background noise, thereby improving the sound collecting effect of the sound collecting apparatus 100. Of course, the sound collecting apparatus 100 can also include at least one microphone 110. In the case that the sound collecting apparatus 100 includes multiple microphones 110, the multiple microphones 110 can be arranged at different positions of the sound collecting apparatus 100 to form an array of microphones 110, which is not limited herein.

[0026] For example, the loudspeaker 120 also has the ability to play sound data.

[0027] In the case that the sound collecting apparatus 100 needs to play corresponding sound data, such as a preset audio signal, through the loudspeaker 120, the sound collecting apparatus 100 can input the preset audio signal in the form of an electric signal to the coil 122 of the loudspeaker 120, so that the coil 122 is in an energized state. The coil 122 can move relative to the magnetic part 123 of the loudspeaker 120 when energized. The coil 122 can drive the diaphragm 121 of the loudspeaker 120 to vibrate when moving. The vibration amplitude and frequency of the diaphragm 121 correspond to the changes of the electric signal corresponding to the preset sound data. Correspondingly, the vibration of the diaphragm 121 can drive the vibration of air molecules in the environment, forming sound waves. These sound waves propagate in the air and eventually reach the human ear and are perceived as sound.

[0028] In some embodiments, the diaphragm 121 of the speaker 120 can be connected with the coil 122 of the speaker 120, and the coil 122 of the speaker 120 is located in the magnetic field provided by the magnetic member 123. When the diaphragm 121 of the speaker 120 vibrates, the diaphragm 121 can drive the coil 122 to vibrate based on the connection relationship between the diaphragm 121 and the coil 122, and the coil 122 cuts the magnetic induction line when vibrating, so that the speaker 120 generates an induced electric signal. When the coil 122 of the speaker 120 moves, such as the coil 122 cutting the magnetic induction line when energized, the coil 122 can drive the diaphragm 121 to vibrate based on the connection relationship between the diaphragm 121 and the coil 122, so that the speaker 120 plays corresponding sound data. Of course, the arrangement of the diaphragm 121, the coil 122 and the magnetic member 123 in the speaker 120 is not limited to this, and is not limited herein.

[0029] In the case that the control module 130 of the sound collecting device 100 is connected with the microphone 110 and the speaker 120, the control module 130 can obtain the signal output by the microphone 110 based on the connection relationship with the microphone 110. Accordingly, the control module 130 can determine whether the sound intensity signal collected by the microphone 110 corresponds to the sound intensity of the environmental sound being greater than or equal to the preset sound intensity threshold according to the signal output by the microphone 110. The preset sound intensity threshold includes, for example, 75 decibels, 76 decibels, 78 decibels, 80 decibels, and the like, and is not limited herein.

[0030] For example, the signal output by the microphone 110 can include an analog signal, and the strength of the signal output by the microphone 110 has a certain corresponding relationship with the size of the sound intensity signal collected by the microphone 110, so that the signal output by the microphone 110 can be used to determine the sound intensity signal collected by the microphone 110. The size of the sound intensity signal collected by the microphone 110 can be used to determine whether the sound intensity of the environmental sound corresponding to the sound intensity signal collected by the microphone 110 is greater than or equal to the preset sound intensity threshold. For example, the size of the voltage or current corresponding to the signal output by the microphone 110 has a corresponding relationship with the size of the sound intensity signal collected by the microphone 110. Moreover, the size of the sound intensity signal collected by the microphone 110 has a certain corresponding relationship with the size of the sound intensity of the environmental sound, such as the sound decibel value of the environmental sound. The control module 130 can determine the size of the sound intensity signal corresponding to the signal output by the microphone 110 based on the corresponding relationship between the size of the voltage or current corresponding to the signal output by the microphone 110 and the size of the sound intensity signal collected by the microphone 110. Accordingly, the control module 130 can determine the size of the sound intensity of the environmental sound corresponding to the sound intensity signal collected by the microphone 110 based on the corresponding relationship between the size of the sound intensity signal collected by the microphone 110 and the size of the sound intensity of the environmental sound, and determine whether the sound intensity of the environmental sound corresponding to the sound intensity signal collected by the microphone 110 is greater than or equal to the preset sound intensity threshold.

[0031] For example, the control module 130 can include an analog-to-digital converter (ADC). When the control module 130 acquires the signal output by the microphone 110, the control module 130 can convert the signal output by the microphone 110 from an analog signal to a digital signal through the ADC. Accordingly, the control module 130 can determine the size of the sound intensity signal collected by the microphone 110 according to the digital signal corresponding to the signal output by the microphone 110. For example, the control module 130 can determine the sound decibel value corresponding to the digital signal according to the digital signal corresponding to the signal output by the microphone 110, and determine the size of the sound intensity signal collected by the microphone 110 according to the sound decibel value corresponding to the digital signal. Accordingly, the control module 130 can determine whether the sound intensity of the environmental sound corresponding to the sound intensity signal collected by the microphone 110 is greater than or equal to the preset sound intensity threshold according to the size of the sound intensity signal collected by the microphone 110.

[0032] Of course, the control module 130 can also include a digital signal processor (DSP), and the sound intensity signal collected by the microphone 110 can be determined by the DSP according to the signal output by the microphone 110. For example, when the control module 130 determines the digital signal corresponding to the signal output by the microphone 110 through the ADC, the control module 130 can further process the digital signal corresponding to the signal output by the microphone 110 through the DSP to obtain a processed digital signal. Accordingly, the control module 130 can determine the sound decibel value corresponding to the processed digital signal according to the processed digital signal corresponding to the signal output by the microphone 110, and determine the size of the sound intensity signal collected by the microphone 110 according to the sound decibel value corresponding to the processed digital signal. Accordingly, the control module 130 can determine whether the sound intensity of the environmental sound corresponding to the sound intensity signal collected by the microphone 110 is greater than or equal to the preset sound intensity threshold according to the size of the sound intensity signal collected by the microphone 110.

[0033] In a case where the control module 130 determines that the sound intensity of the sound intensity signal collected by the microphone 110 corresponds to the environmental sound and the sound intensity is greater than or equal to the preset sound intensity threshold, the sound collecting device 100 can determine that the signal output by the microphone 110 is not suitable for being converted into the second sound data. If the signal output by the microphone 110 is converted into the second sound data, the second sound data can have sound distortion, which can result in poor sound collecting effect of the microphone 110. In a case where the sound collecting device 100 collects sound only through the microphone 110, the sound collecting effect of the sound collecting device 100 can be poor. Based on this, in a case where the sound collecting device 100 includes at least one microphone 110 and at least one loudspeaker 120, the sound collecting device 100 can collect sound through the loudspeaker 120 instead of or in cooperation with the microphone 110. In a case where the sound intensity of the environmental sound is greater than or equal to the preset sound intensity threshold, the sound collecting effect of the loudspeaker 120 is better than that of the microphone 110. For example, the diaphragm 121 of the loudspeaker 120 will not be overloaded or oversaturated in a case where the sound intensity of the environmental sound is greater than or equal to the preset sound intensity threshold due to the large displacement of the diaphragm 121. Based on this, the first sound data corresponding to the induced electric signal generated by the loudspeaker 120 in a case where the sound intensity of the environmental sound is greater than or equal to the preset sound intensity threshold will not be prone to sound distortion. In a case where sound is collected through the loudspeaker 120 instead of or in cooperation with the microphone 110, the sound collecting device 100 can convert the induced electric signal generated by the loudspeaker 120 into the first sound data through the control module 130. The first sound data does not have sound distortion, which is conducive to improving the sound collecting effect of the sound collecting device 100.

[0034] In some embodiments, the loudspeaker 120 further includes a power amplifier 124; in a case where the power amplifier 124 is turned off and the diaphragm 121 vibrates, the coil 122 moves relative to the magnetic piece 123, so that the coil 122 generates an induced electric signal.

[0035] As Figure 2As shown, the loudspeaker 120 in the sound collecting apparatus 100 further comprises a power amplifier 124. The power amplifier 124 of the loudspeaker 120 can be used to indicate whether the loudspeaker 120 is playing sound data. For example, when the power amplifier 124 of the loudspeaker 120 is turned on, the power amplifier 124 can perform power amplification processing on the received sound data, such as a preset audio signal, to obtain a power-amplified preset audio signal. When the power of the power-amplified preset audio signal is greater than or equal to a corresponding sound production power threshold of the loudspeaker 120, the amplified preset audio signal can drive the loudspeaker 120 to produce sound, so that the loudspeaker 120 plays the amplified preset audio signal. For example, the amplified preset audio signal can cause the coil 122 of the loudspeaker 120 to be electrified, thereby causing the relative movement between the coil 122 and the magnetic member 123 of the loudspeaker 120. Accordingly, the coil 122 can drive the diaphragm 121 of the loudspeaker 120 to vibrate in the process of relative movement with the magnetic member 123, thereby generating sound waves. The sound waves propagate in the air and eventually reach the human ear and are perceived as sound.

[0036] Accordingly, when the power amplifier 124 of the loudspeaker 120 is turned off, the power amplifier 124 will not perform power amplification processing on the sound data, such as the preset audio signal. The power of the preset audio signal without power amplification processing is less than the corresponding sound production power threshold of the loudspeaker 120, so the loudspeaker 120 cannot be driven to produce sound, thereby making the loudspeaker 120 unable to play the preset audio signal.

[0037] Based on this, when the power amplifier 124 of the loudspeaker 120 is turned on, it can be determined that the loudspeaker 120 is playing sound data. When the power amplifier 124 of the loudspeaker 120 is turned off, it can be determined that the loudspeaker 120 is not playing sound data.

[0038] When the power amplifier 124 of the loudspeaker 120 is turned off, since the loudspeaker 120 cannot play sound data, such as a preset audio signal, when the diaphragm 121 of the loudspeaker 120 vibrates, it can be determined that the vibration of the diaphragm 121 is caused by the ambient sound existing in the environment where the sound collecting apparatus 100 is located. For example, when the power amplifier 124 is turned off and the coil 122 and the magnetic member 123 move relative to each other to cause the coil 122 to generate an induced electric signal when the diaphragm 121 vibrates. The induced electric signal generated by the loudspeaker 120 can be used as a sound signal collected by the loudspeaker 120 to determine the first sound data.

[0039] Based on this, in the case that the loudspeaker 120 has the capability of collecting sound signals and the capability of playing sound data, it can be ensured that the loudspeaker 120 collects sound signals in the case that the loudspeaker 120 does not play sound data, so as to avoid the conflict between the process of the loudspeaker 120 collecting sound signals and the process of the loudspeaker 120 playing sound data, thereby ensuring the working stability of the loudspeaker 120.

[0040] In some embodiments, the control module 130 is connected to the power amplifier 124, and the control module 130 is configured to convert the induced electric signal generated by the loudspeaker 120 into first sound data in the case that the sound intensity signal collected by the microphone 110 corresponds to environmental sound with a sound intensity greater than or equal to a preset sound intensity threshold, and the power amplifier 124 is turned off.

[0041] For example, as shown in FIG. 1, in the case that the control module 130 is connected to the power amplifier 124, the control module 130 can obtain the working state of the power amplifier 124 based on the connection relationship between the control module 130 and the power amplifier 124, such as determining that the power amplifier 124 is turned on or determining that the power amplifier 124 is turned off. Figure 2

[0042] In an exemplary embodiment, the power amplifier 124 of the loudspeaker 120 generates a corresponding control signal when the power amplifier 124 is turned on or turned off. The control module 130 can obtain the control signal based on the connection relationship between the control module 130 and the power amplifier 124, so as to determine that the power amplifier 124 is turned on or determine that the power amplifier 124 is turned off according to the control signal. For example, the control module 130 can include a DSP, and the DSP is provided with a monitoring circuit. The DSP is connected to the power amplifier 124 of the loudspeaker 120, so that the DSP can obtain the control signal generated by the power amplifier 124 when the power amplifier 124 is turned on or turned off, and identify the level change of the control signal, thereby determining that the power amplifier 124 is turned on or determining that the power amplifier 124 is turned off.

[0043] Correspondingly, in the case that it is determined that the power amplifier 124 is turned on, the control module 130 can determine that the loudspeaker 120 is playing sound data. In the case that it is determined that the power amplifier 124 is turned off, the control module 130 can determine that the loudspeaker 120 is not playing sound data. In the case that the loudspeaker 120 is not playing sound data, the loudspeaker 120 can generate an induced electric signal in response to the environmental sound of the environment in which the sound collecting device 100 is located.

[0044] ​In a case that the sound intensity signal collected by the microphone 110 corresponds to the sound intensity of the ambient sound being greater than or equal to the preset sound intensity threshold, and the power amplifier 124 is turned off, the control module 130 can collect sound through the loudspeaker 120 instead of or in cooperation with the microphone 110, and then convert the induced electric signal generated by the loudspeaker 120 into the first sound data. The first sound data does not have sound distortion, which is conducive to improving the sound collection effect of the sound collection device 100.

[0045] In some embodiments, the control module 130 is further configured to stop converting the induced electric signal generated by the loudspeaker 120 into the first sound data in a case that the first sound data corresponds to the sound intensity of the ambient sound being less than the preset sound intensity threshold, and / or the sound intensity signal collected by the microphone 110 corresponds to the sound intensity of the ambient sound being less than the preset sound intensity threshold.

[0046] In a case that the control module 130 obtains the first sound data, the control module 130 can determine the sound intensity of the ambient sound corresponding to the first sound data. For example, the control module 130 can determine the sound decibel value corresponding to the first sound data, so as to indicate the magnitude of the sound intensity of the ambient sound through the sound decibel value corresponding to the first sound data. Accordingly, the control module 130 can determine whether the magnitude of the sound intensity of the ambient sound corresponding to the first sound data is less than the preset sound intensity threshold. In a case that the control module 130 determines that the sound intensity of the ambient sound corresponding to the first sound data is less than the preset sound intensity threshold, the control module 130 can determine that it is not necessary to continue to collect sound through the loudspeaker 120 instead of or in cooperation with the microphone 110, and then the control module 130 can stop converting the induced electric signal generated by the loudspeaker 120 into the first sound data.

[0047] Of course, the control module 130 may, for example, stop converting the signal output by the microphone 110 into the second sound data in a process that the loudspeaker 120 collects sound instead of the microphone 110. Accordingly, in a case that the control module 130 stops converting the induced electric signal generated by the loudspeaker 120 into the first sound data, the control module 130 can restore converting the signal output by the microphone 110 into the second sound data. For another example, the control module 130 may, for example, not stop converting the signal output by the microphone 110 into the second sound data in a process that the loudspeaker 120 collects sound in cooperation with the microphone 110, and then the control module 130 can stop converting the induced electric signal generated by the loudspeaker 120 into the first sound data, and keep converting the signal output by the microphone 110 into the second sound data.

[0048] Based on this, the control module 130 of the sound collecting device 100 can take different strategies to convert at least one of the induced electric signal generated by the loudspeaker 120 and the signal output by the microphone 110 into corresponding sound data according to the sound intensity of the environmental sound corresponding to the first sound data of the induced electric signal generated by the loudspeaker 120 and the sound intensity signal collected by the microphone 110, thereby facilitating improvement of the sound collecting flexibility of the sound collecting device 100.

[0049] In some embodiments, the control module 130 is further configured to convert the signal output by the microphone 110 into second sound data.

[0050] For example, the control module 130 can convert the signal output by the microphone 110 into second sound data regardless of whether the sound intensity signal collected by the microphone 110 corresponds to environmental sound with a sound intensity greater than or equal to a preset sound intensity threshold when the signal output by the microphone 110 is obtained.

[0051] In an exemplary embodiment, the control module 130 can include at least one ADC and at least one DSP. The control module 130 can implement at least one of conversion of the signal output by the microphone 110 into second sound data and conversion of the induced electric signal generated by the loudspeaker 120 into first sound data through different ADCs and DSPs. The control module 130 can also implement at least one of conversion of the signal output by the microphone 110 into second sound data and conversion of the induced electric signal generated by the loudspeaker 120 into first sound data through the same ADC and DSP, which is not limited herein.

[0052] In some embodiments, the control module 130 is further configured to convert the signal output by the microphone 110 into second sound data when the sound intensity signal collected by the microphone 110 corresponds to environmental sound with a sound intensity less than a preset sound intensity threshold and / or when the first sound data corresponds to environmental sound with a sound intensity less than a preset sound intensity threshold.

[0053] For example, the control module 130 can convert the signal output by the microphone 110 into second sound data only when the sound intensity signal collected by the microphone 110 corresponds to environmental sound with a sound intensity less than a preset sound intensity threshold when the signal output by the microphone 110 is obtained.

[0054] For example, the control module 130 can determine the sound intensity of the environmental sound corresponding to the first sound data in the case of converting the induced electric signal generated by the speaker 120 into the first sound data. In the case that the sound intensity of the environmental sound corresponding to the first sound data is less than the preset sound intensity threshold, the control module 130 can resume converting the signal output by the microphone 110 into the second sound data, and stop converting the induced electric signal generated by the speaker 120 into the first sound data.

[0055] Correspondingly, the control module 130 can still determine the sound intensity signal collected by the microphone 110 according to the signal output by the microphone 110 in the process of converting the induced electric signal generated by the speaker 120 into the first sound data. Accordingly, the control module 130 can convert the signal output by the microphone 110 into the second sound data when the sound intensity signal collected by the microphone 110 corresponds to the environmental sound whose sound intensity is less than the preset sound intensity threshold, and the first sound data corresponds to the environmental sound whose sound intensity is less than the preset sound intensity threshold.

[0056] In some embodiments, the control module 130 is further configured to stop converting the signal output by the microphone 110 into the second sound data when the sound intensity signal collected by the microphone 110 corresponds to the environmental sound whose sound intensity is greater than or equal to the preset sound intensity threshold, and / or the first sound data corresponds to the environmental sound whose sound intensity is greater than or equal to the preset sound intensity threshold.

[0057] For example, the control module 130 can stop converting the signal output by the microphone 110 into the second sound data when the sound intensity signal collected by the microphone 110 corresponds to the environmental sound whose sound intensity is greater than or equal to the preset sound intensity threshold in the case of obtaining the signal output by the microphone 110.

[0058] For example, the control module 130 can determine the sound intensity of the environmental sound corresponding to the first sound data in the case of converting the induced electric signal generated by the speaker 120 into the first sound data. In the case that the sound intensity of the environmental sound corresponding to the first sound data is greater than or equal to the preset sound intensity threshold, the control module 130 can stop converting the signal output by the microphone 110 into the second sound data. Accordingly, the control module 130 can continue to convert the induced electric signal generated by the speaker 120 into the first sound data.

[0059] Correspondingly, in the process of converting the induced electric signal generated by the loudspeaker 120 into the first sound data, the microphone 110 can still output a signal, and the control module 130 can still determine the sound intensity signal of the sound collected by the microphone 110 according to the signal output by the microphone 110. Correspondingly, the control module 130 can also stop converting the signal output by the microphone 110 into the second sound data when the sound intensity of the environmental sound corresponding to the sound intensity signal collected by the microphone 110 is greater than or equal to the preset sound intensity threshold, and the sound intensity of the environmental sound corresponding to the first sound data is greater than or equal to the preset sound intensity threshold.

[0060] Based on this, the control module 130 of the sound collection device 100 can convert the signal output by the microphone 110 into the second sound data or stop converting the signal output by the microphone 110 into the second sound data according to at least one of the sound intensity of the environmental sound corresponding to the first sound data corresponding to the induced electric signal generated by the loudspeaker 120 and the sound intensity signal collected by the microphone 110, thereby facilitating improvement of the sound collection flexibility of the sound collection device 100.

[0061] In some embodiments, the control module 130 is further configured to perform signal fusion processing on the signal output by the microphone 110 and the induced electric signal generated by the loudspeaker 120 to obtain a processed signal, and convert the processed signal into third sound data.

[0062] For example, the sound collection device 100 can collect sound through the loudspeaker 120 and the microphone 110. In the case that the loudspeaker 120 and the microphone 110 each collect a sound signal, such as the induced electric signal generated by the loudspeaker 120 and the signal output by the microphone 110, the control module 130 can perform signal fusion processing on the signal output by the microphone 110 and the induced electric signal generated by the loudspeaker 120 to obtain a processed signal, and convert the processed signal into third sound data.

[0063] In an exemplary embodiment, the control module 130 is further configured to perform signal fusion processing on the signal output by the microphone 110 and the induced electric signal generated by the loudspeaker 120 when the sound intensity of the environmental sound is greater than or equal to the preset sound intensity threshold, to obtain a processed signal, and convert the processed signal into third sound data. At this time, the sound collection device 100 can use the mid-high frequency sound signal picked up by the loudspeaker 120 and all sound signals picked up by the microphone 110 to perform signal fusion processing and noise reduction, thereby determining the third sound data.

[0064] Based on this, the sound collecting device 100 can comprehensively utilize the sound signals collected by the microphone 110 and the loudspeaker 120 respectively, to convert the sound signals collected by the microphone 110 and the sound signals collected by the loudspeaker 120 into the same sound data, thereby facilitating the improvement of the sound collecting flexibility of the sound collecting device 100.

[0065] The sound collecting device 100 provided by the embodiment of the present application comprises at least one microphone 110, at least one loudspeaker 120, a control module 130, wherein the loudspeaker 120 comprises a diaphragm 121, a coil 122 and a magnetic piece 123; the coil 122 moves relative to the magnetic piece 123 when the coil 122 is electrified, so as to make the diaphragm 121 vibrate, and the coil 122 moves relative to the magnetic piece 123 when the diaphragm 121 vibrates, so that the coil 122 generates an induced electric signal; the control module 130 is connected with the microphone 110 and the loudspeaker 120, and the control module 130 is used for acquiring the signal output by the microphone 110, and acquiring the induced electric signal generated by the loudspeaker 120 when the sound intensity signal collected by the microphone 110 corresponds to the sound intensity of the environmental sound which is greater than or equal to a preset sound intensity threshold, and converting the induced electric signal generated by the loudspeaker 120 into first sound data.

[0066] The loudspeaker 120 moves relative to the magnetic piece 123 when the coil 122 is electrified, so as to make the diaphragm 121 vibrate, and the loudspeaker 120 can be used for playing corresponding sound data. The coil 122 moves relative to the magnetic piece 123 when the diaphragm 121 vibrates, so that the coil 122 generates an induced electric signal. The induced electric signal can be used for determining the first sound data, and the loudspeaker 120 can be used for collecting sound signals. The control module 130 can determine that the signal output by the microphone 110 is not suitable for being converted into second sound data when the sound intensity signal collected by the microphone 110 corresponds to the sound intensity of the environmental sound which is greater than or equal to the preset sound intensity threshold. If the signal output by the microphone 110 is converted into the second sound data, the second sound data will have sound distortion, resulting in poor sound collecting effect of the microphone 110. When the sound intensity of the environmental sound is greater than or equal to the preset sound intensity threshold, the sound collecting effect of the loudspeaker 120 is better than that of the microphone 110. Based on this, the sound collecting device 100 can convert the induced electric signal generated by the loudspeaker 120 into the first sound data through the control module 130, so as to improve the sound collecting effect of the sound collecting device 100.

[0067] Please refer to Figure 3 , Figure 3 is a structural schematic diagram of an AR glasses 10 provided by the embodiment of the present application.

[0068] As Figure 3As shown, the AR glasses 10 include a hingedly connected frame and temples, a first accommodating space is formed in the frame, and a second accommodating space is formed in the temples, and the first accommodating space and / or the second accommodating space is used to accommodate the aforementioned sound collecting device 100.

[0069] The sound collecting device 100 can be arranged on the AR glasses 10. For example, in the case where the AR glasses 10 include a frame and temples, the sound collecting device 100 can be arranged in a first accommodating space formed in the frame, or in a second accommodating space formed in the temples, or distributed in the first accommodating space and the second accommodating space, without limitation.

[0070] For example, the microphone 110 of the sound collecting device 100 can be arranged in at least one of a front side area of the frame included in the first accommodating space, a temple housing area included in the second accommodating space, and a frame shoulder area included in the first accommodating space. The speaker 120 of the sound collecting device 100 can be arranged in at least one of the temple housing area included in the second accommodating space and the front side area of the frame included in the first accommodating space. In the case where the speaker 120 is arranged in the temple housing area, it can also be arranged at a position close to the user's ear in the temple housing area, without limitation.

[0071] Of course, the arrangement positions of the microphone 110 and the speaker 120 on the AR glasses 10 are not limited thereto. For example, in the case where the sound collecting device 100 includes a plurality of speakers 120, the plurality of speakers 120 can be distributed at different positions of at least one of the first accommodating space and the second accommodating space included in the AR glasses 10. Correspondingly, in the case where the sound collecting device 100 includes a plurality of microphones 110, the plurality of microphones 110 can be distributed at different positions of at least one of the first accommodating space and the second accommodating space included in the AR glasses 10. Wherein, the arrangement position of the speaker 120 on the AR glasses 10 is different from the arrangement position of the microphone 110 on the AR glasses 10, without limitation.

[0072] The AR glasses 10 can realize the sound collecting capability and the sound playing capability of the AR glasses 10 through the sound collecting device 100.

[0073] For example, when the AR glasses 10 collect the environmental sound of the environment through the sound collection device 100, the microphone 110 of the sound collection device 100 can output a signal, and the speaker 120 of the sound collection device 100 can generate a sensing electric signal. The control module 130 of the sound collection device 100 can obtain the signal output by the microphone 110, and when the sound intensity signal collected by the microphone 110 corresponds to the sound intensity of the environmental sound being greater than or equal to a preset sound intensity threshold, the control module 130 can obtain the sensing electric signal generated by the speaker 120, and convert the sensing electric signal generated by the speaker 120 into first sound data.

[0074] Correspondingly, in the case that the microphone 110 and the speaker 120 of the sound collection device 100 are respectively arranged at different positions of the AR glasses 10, the AR glasses 10 can process and analyze the sound signals collected by the sound collection device 100 at different positions, such as the signal output by the microphone 110 and the sensing electric signal generated by the speaker 120, to realize the functions of positioning the sound source, enhancing the target sound, and suppressing the background noise, so as to improve the sound collection accuracy and the clarity of the AR glasses 10, thereby improving the sound collection effect of the AR glasses 10.

[0075] The related description of the sound collection device 100 included in the AR glasses 10 in the embodiment can refer to the related description of the sound collection device 100 in the foregoing embodiments, which will not be described herein again.

[0076] In some embodiments, the microphone 110 and the speaker 120 of the sound collection device 100 are respectively arranged in the first accommodating space and the second accommodating space, or the microphone 110 and the speaker 120 of the sound collection device 100 are respectively arranged in the second accommodating space and the first accommodating space.

[0077] For example, the microphone 110 and the speaker 120 of the sound collection device 100 can be distributed and arranged at different positions of the AR glasses 10. For example, when the microphone 110 is arranged in the first accommodating space, the speaker 120 can be arranged in the second accommodating space. For another example, when the microphone 110 is arranged in the second accommodating space, the speaker 120 can be arranged in the first accommodating space. In the case that the microphone 110 is arranged in one of the first accommodating space and the second accommodating space, and the speaker 120 is arranged in the other one of the first accommodating space and the second accommodating space, the microphone 110 and the speaker 120 can form a corresponding sound collection array to collect the same environmental sound at different arrangement positions, which is conducive to improving the sound collection effect of the AR glasses 10.

[0078] The AR glasses 10 provided by the embodiments of the present application include a hingedly connected frame and temples, a first accommodating space is formed in the frame, a second accommodating space is formed in the temples, the first accommodating space and / or the second accommodating space is used for accommodating the sound collecting device 100, then the AR glasses 10 can utilize the sound collecting capability and the sound playing capability of the sound collecting device 100 to realize the sound collecting capability and the sound playing capability of the AR glasses 10. Correspondingly, in the case that the sound collecting effect of the sound collecting device 100 is improved, the sound collecting effect of the AR glasses 10 can also be improved.
