Technical Field

[0002] The present invention relates to the technical field of smart helmets, and in particular to a reverberation suppression method, device, equipment and storage medium. Background Art

[0003] In recent years, AR (augmented reality) smart devices have been widely favored by more and more users, such as smart helmets. While bringing a sense of technology to users, smart devices also provide convenience for users' daily lives. For example, users can wear smart helmets to listen to music, watch TV series, exercise and other daily activities, and are no longer restricted by the traditional wearing method that requires handheld or headphone connection. However, taking the smart helmet as an example, the smart helmet is an almost completely enclosed space. If multiple electroacoustic transducers are installed in the smart helmet, that is, it is used in reverberation scenarios, there will be cross-propagation when the sound reaches the user's ears. To solve the above defects, the commonly used method of suppressing reverberation is to remove the reverberation part in the sound signal by optimizing the speech spectrum. However, the optimization of the speech spectrum is inseparable from the multiple conversions of the signal between the time domain and the frequency domain, and the speech signal is easily lost during the conversion process, which ultimately results in low efficiency and accuracy in suppressing reverberation.

[0004] The above content is only used to assist in understanding the technical solution of the present invention and does not constitute an admission that the above content is prior art.

[0053] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0054] 1 , which is a schematic diagram of the structure of a reverberation suppression device in a hardware operating environment according to an embodiment of the present invention.

[0055] As shown in FIG1 , the reverberation suppression device may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to implement communication between these components. The user interface 1003 may include a display and an input unit such as a keyboard. Optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a wireless fidelity (Wi-Fi) interface). The memory 1005 may be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as a disk storage device. The memory 1005 may also be a storage device independent of the processor 1001.

[0056] Those skilled in the art will appreciate that the structure shown in FIG. 1 does not limit the reverberation suppression device, and may include more or fewer components than shown, or combine certain components, or arrange the components differently.

[0057] As shown in FIG. 1 , the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module, and a reverberation suppression program.

[0058] In the reverberation suppression device shown in FIG1 , the network interface 1004 is primarily used for data communication with a network integration platform workstation; the user interface 1003 is primarily used for data interaction with a user; the processor 1001 and the memory 1005 in the reverberation suppression device of the present invention may be provided within the reverberation suppression device. The reverberation suppression device invokes a reverberation suppression program stored in the memory 1005 via the processor 1001 and executes the reverberation suppression method provided in an embodiment of the present invention.

[0059] Based on the above hardware structure, an embodiment of the reverberation suppression method of the present invention is proposed.

[0060] 2 , which is a flow chart of a first embodiment of a reverberation suppression method according to the present invention.

[0061] In a first embodiment, the reverberation suppression method includes the following steps:

[0062] Step S10: obtaining the current leakage volume of the electroacoustic transducer in the reverberation scene.

[0063] It should be noted that the execution subject of this embodiment is a reverberation suppression device, and it can also be other devices that can achieve the same or similar functions, such as a smart helmet, etc. This embodiment does not limit this. In this embodiment, a smart helmet is used as an example for illustration.

[0064] It should be understood that the current leakage volume refers to the leakage volume of the electroacoustic transducer in a reverberation scene. The current leakage volume can be obtained by real-time monitoring through a sound leakage monitoring device corresponding to the electroacoustic transducer. The electroacoustic transducer can be a loudspeaker, and the sound leakage monitoring device can be a sound leakage monitoring microphone. The reverberation scene refers to a scene in which two or more electroacoustic transducers play sound at the same time in a confined space.

[0065] Step S20 : ​​When the current leakage volume is greater than a preset leakage volume threshold, obtaining the current loudness of the electroacoustic transducer device.

[0066] It can be understood that the current loudness refers to the loudness of the sound played by the electroacoustic transducer at the current moment. After obtaining the current leakage volume of the electroacoustic transducer in the reverberation scene, it is determined whether the current leakage volume is greater than the preset leakage volume threshold. If so, it indicates that the sound played by the left electroacoustic transducer will reach the user's right ear, and the sound played by the right electroacoustic transducer will reach the user's left ear. At this time, the current loudness of the electroacoustic transducer needs to be reduced.

[0067] Furthermore, step S20 includes: when the current leakage volume of the left electro-acoustic transducer device and the current leakage volume of the right electro-acoustic transducer device are both greater than a preset leakage volume threshold, obtaining the current loudness of the left electro-acoustic transducer device and the current loudness of the right electro-acoustic transducer device; and correspondingly reducing the current loudness of the electro-acoustic transducer device, including: reducing the current loudness of the left electro-acoustic transducer device and the current loudness of the right electro-acoustic transducer device respectively.

[0068] It should be understood that, taking two right electroacoustic transducers as an example, namely the left electroacoustic transducer and the right electroacoustic transducer, the shapes of the left electroacoustic transducer and the right electroacoustic transducer are similar to the shapes of the user's ears, that is, the left electroacoustic transducer can almost completely fit the ear. Referring to Figure 3, Figure 3 is a schematic diagram of the position of the right device, specifically including the right electroacoustic transducer and the right sound leakage monitoring device, and the right sound leakage monitoring device is arranged at the tragus of the right electroacoustic transducer on the inside of the smart helmet. Referring to Figure 4, Figure 4 is a schematic diagram of the position of the left device, specifically including the left electroacoustic transducer and the left sound leakage monitoring device, and the left sound leakage monitoring device is arranged at the tragus of the left electroacoustic transducer on the inside of the smart helmet.

[0069] It can be understood that when the current leakage volume of the left electro-acoustic transducer device and the current leakage volume of the right electro-acoustic transducer device are both greater than the preset leakage volume threshold, it indicates that the loudness of the left electro-acoustic transducer device and the right electro-acoustic transducer device need to be reduced, that is, the current loudness of the left electro-acoustic transducer device and the current loudness of the right electro-acoustic transducer device are reduced respectively to avoid the sound played by the left electro-acoustic transducer device reaching the user's right ear and the sound played by the right electro-acoustic transducer device reaching the user's left ear.

[0070] Further, step S20 includes: when the current leakage volume of the left electro-acoustic transducer device is greater than a preset leakage volume threshold and the current leakage volume of the right electro-acoustic transducer device is less than or equal to the preset leakage volume threshold, obtaining the current loudness of the left electro-acoustic transducer device; and correspondingly reducing the current loudness of the electro-acoustic transducer device, including: reducing the current loudness of the left electro-acoustic transducer device; when the current leakage volume of the right electro-acoustic transducer device is greater than the preset leakage volume threshold and the current leakage volume of the left electro-acoustic transducer device is less than or equal to the preset leakage volume threshold, obtaining the current loudness of the right electro-acoustic transducer device; and correspondingly reducing the current loudness of the electro-acoustic transducer device, including: reducing the current loudness of the right electro-acoustic transducer device.

[0071] It can be understood that when it is determined that the current leakage volume of the left electro-acoustic transducer device is greater than the preset leakage volume threshold and the current leakage volume of the right electro-acoustic transducer device is less than or equal to the preset leakage volume threshold, it indicates that the loudness of the right electro-acoustic transducer device does not need to be adjusted, and the current loudness of the left electro-acoustic transducer device is reduced at this time. When it is determined that the current leakage volume of the right electro-acoustic transducer device is greater than the preset leakage volume threshold and the current leakage volume of the left electro-acoustic transducer device is less than or equal to the preset leakage volume threshold, it indicates that the loudness of the left electro-acoustic transducer device does not need to be adjusted, and the current loudness of the right electro-acoustic transducer device is reduced at this time.

[0072] Step S30: reducing the current loudness of the electroacoustic transducer.

[0073] It should be understood that after obtaining the current loudness of the electroacoustic transducer device whose current leakage volume is greater than the preset leakage volume threshold, the current loudness of the electroacoustic transducer device is reduced.

[0074] This embodiment obtains the current leakage volume of the electroacoustic transducer in a reverberation scene; when the current leakage volume is greater than a preset leakage volume threshold, obtains the current loudness of the electroacoustic transducer; and reduces the current loudness of the electroacoustic transducer. In the above manner, after obtaining the current leakage volume of the electroacoustic transducer in the reverberation scene, it is determined whether the current leakage volume is greater than the preset leakage volume threshold. If so, the current loudness of the electroacoustic transducer is reduced, thereby effectively improving the efficiency and accuracy of suppressing reverberation in the reverberation scene, improving voice clarity, and thereby improving the user experience.

[0075] In one embodiment, as shown in FIG5 , a second embodiment of the reverberation suppression method of the present invention is proposed based on the first embodiment. After step S30, the method further includes:

[0076] Step S401: Determine a sound leakage monitoring device corresponding to the electroacoustic transducer device, where the sound leakage monitoring device is arranged at the tragus of the electroacoustic transducer device on the inner side of the smart helmet.

[0077] It should be understood that there is a one-to-one correspondence between the electroacoustic transducer and the sound leakage monitoring device. For example, the right electroacoustic transducer corresponds to the right sound leakage monitoring device, and the left electroacoustic transducer corresponds to the left sound leakage monitoring device.

[0078] Step S402: obtaining, by the sound leakage monitoring device, a target leakage volume of the electroacoustic transducer after the loudness is reduced.

[0079] It is understandable that the target leakage volume refers to the leakage volume of the electroacoustic transducer after the loudness is reduced. The target leakage volume can also be obtained by real-time monitoring through a sound leakage monitoring device.

[0080] Step S403: When the target leakage volume is less than or equal to the preset leakage volume threshold, determine the leakage volume threshold preferred by the user.

[0081] It should be understood that the user-preferred leakage volume threshold refers to the user's preferred threshold for reverberation. After obtaining the target leakage volume of the electroacoustic transducer after reducing the loudness, it is determined whether the target leakage volume is less than or equal to the preset leakage volume threshold. If so, it indicates that the target leakage volume will not affect the user's use of the smart helmet to make calls or play music, that is, the target leakage volume is used as the user-preferred leakage volume threshold.

[0082] Further, step S403 includes: when the target leakage volume is less than or equal to a preset leakage volume threshold, determining whether a leakage volume adjustment request is received; when the leakage volume adjustment request is received, determining the adjustment type of the leakage volume adjustment request; when the adjustment type is a voice adjustment type, adjusting the loudness of the electroacoustic transducer device according to a default adjustment ratio; when no leakage volume adjustment request is received, obtaining a first leakage volume of the electroacoustic transducer device after the loudness is reduced through the sound leakage monitoring device, and using the first leakage volume as the leakage volume threshold preferred by the user.

[0083] It can be understood that the leakage volume adjustment request refers to a request sent by the user to the smart helmet to adjust the leakage volume. When the leakage volume adjustment request is received, it indicates that the user is still dissatisfied with the target leakage volume. At this time, the adjustment type of the leakage volume adjustment request is determined. When it is determined that the adjustment type is a voice adjustment type, it indicates that the user sends a leakage volume adjustment request by voice, for example, "The current leakage volume is still a bit loud, please continue to lower it." After receiving the leakage volume adjustment request, the smart helmet adjusts the loudness of the electroacoustic transducer according to the default adjustment ratio. The default adjustment ratio can be 3%. After the adjustment is completed, it continues to determine whether the leakage volume adjustment request is received. If not, it indicates that the user is satisfied with the first leakage volume of the electroacoustic transducer after adjusting the loudness. At this time, the first leakage volume is used as the leakage volume threshold preferred by the user.

[0084] Furthermore, upon receiving a leakage volume adjustment request, after determining the adjustment type of the leakage volume adjustment request, the method further includes: if the adjustment type is a key adjustment type, determining the number of adjustments within a preset time period; determining a total loudness adjustment value based on the number of adjustments and a single loudness adjustment value; adjusting the loudness of the electro-acoustic transducer device based on the total loudness adjustment value; and, if no leakage volume adjustment request is received, obtaining, via the sound leakage monitoring device, a second leakage volume of the electro-acoustic transducer device after the loudness is reduced, and using the second leakage volume as a leakage volume threshold preferred by the user.

[0085] It should be understood that when the adjustment type of the leakage volume adjustment request is determined to be a key adjustment type, indicating that the user has issued a leakage volume adjustment request by pressing a key, the number of adjustments within a preset time period is determined, and then a total loudness adjustment value is determined in combination with the single loudness adjustment value. For example, if the user pressed the button four times and the single loudness adjustment value was 3, the total loudness adjustment value is 12. The loudness of the electro-acoustic transducer device is then adjusted based on the total loudness adjustment value. After the adjustment is completed, it is determined whether a leakage volume adjustment request has been received. If not, it indicates that the user is satisfied with the second leakage volume of the electro-acoustic transducer device after the loudness adjustment. In this case, the second leakage volume is used as the user's preferred leakage volume threshold.

[0086] Furthermore, after step S403, the method further includes: updating the preset leakage volume threshold according to the leakage volume threshold preferred by the user.

[0087] It can be understood that after determining the leakage volume threshold preferred by the user, the preset leakage volume threshold is updated according to the leakage volume threshold preferred by the user, that is, the leakage volume threshold preferred by the user is used as the preset leakage volume threshold for the user to make calls or play music next time using the smart helmet to improve the user experience.

[0088] This embodiment determines a sound leakage monitoring device corresponding to the electroacoustic transducer device, and the sound leakage monitoring device is arranged at the auricle of the electroacoustic transducer device on the inside of the smart helmet; obtains the target leakage volume of the electroacoustic transducer device after reducing the loudness through the sound leakage monitoring device; when the target leakage volume is less than or equal to the preset leakage volume threshold, determines the leakage volume threshold preferred by the user; through the above method, after determining the sound leakage monitoring device corresponding to the electroacoustic transducer device, obtains the target leakage volume of the electroacoustic transducer device after reducing the loudness through the sound leakage monitoring device, and then determines whether the target leakage volume is less than or equal to the preset leakage volume threshold. If so, the target leakage volume is used as the leakage volume threshold preferred by the user, thereby effectively improving the accuracy of determining the leakage volume threshold preferred by the user, thereby improving the user experience.

[0089] In addition, an embodiment of the present invention further provides a storage medium, on which a reverberation suppression program is stored. When the reverberation suppression program is executed by a processor, the steps of the reverberation suppression method described above are implemented.

[0090] Since the storage medium adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0091] In addition, referring to FIG6 , an embodiment of the present invention further provides a reverberation suppression device, the reverberation suppression device comprising:

[0092] The acquisition module 10 is used to obtain the current leakage volume of the electroacoustic transducer in the reverberation scene.

[0094] The reducing module 30 is configured to reduce the current loudness of the electroacoustic transducer.

[0095] This embodiment obtains the current leakage volume of the electroacoustic transducer in a reverberation scene; when the current leakage volume is greater than a preset leakage volume threshold, obtains the current loudness of the electroacoustic transducer; and reduces the current loudness of the electroacoustic transducer. In the above manner, after obtaining the current leakage volume of the electroacoustic transducer in the reverberation scene, it is determined whether the current leakage volume is greater than the preset leakage volume threshold. If so, the current loudness of the electroacoustic transducer is reduced, thereby effectively improving the efficiency and accuracy of suppressing reverberation in the reverberation scene, improving voice clarity, and thereby improving the user experience.
