[0060] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0061] The following describes a method, device, vehicle, electronic device, and storage medium for reducing escaped sound waves according to embodiments of the present disclosure with reference to the accompanying drawings.

[0062] Figure 1 A schematic diagram of a method for reducing escaped sound waves provided by an embodiment of the present disclosure is provided. The method is applied in a vehicle computer, such as Figure 1 As shown, the method comprises the following steps:

[0063] Step 101, determining a first amplitude and a first phase of an escaped sound wave corresponding to the audio to be played, wherein the escaped sound wave is a sound wave that overflows out of an ear of a subject listening to the audio to be played.

[0064] The vehicle's computer sends the audio to be played to the ANC headphones equipped on the vehicle's headrest through wireless or wired communication methods. After receiving the audio, the ANC headphones amplify the power through a preset power amplifier and then play the sound through the left and right speakers of the ANC headphones. During the playback process, most of the sound of the audio to be played will enter the wearer's ears, and a small part of the sound will escape from the human ears. The escape directions include but are not limited to the front and side and rear directions. Among them, the forward direction will not propagate toward other users. At the same time, as the sound attenuates in the air and is absorbed by other objects, it is difficult to form an effective amplitude to interfere with other passengers. However, it should be noted that the side and rear sound, if not controlled, will be directly transmitted to the positions of other passengers, thereby interfering with the sound field of other passengers. In the embodiment of the present application, the sound of the audio to be played overflowing from the human ear and propagating to the side and rear directions is called an escape sound wave.

[0065] In order to facilitate the understanding of escape sound waves, Figure 2 As shown, Figure 2 A schematic diagram of an escaped sound wave provided in an embodiment of the present application, wherein after a user wears headphones equipped with a seat, the sound waves to the side and rear are escaped sound waves, wherein the side and rear are sound waves that overflow from the headphones to the side and rear when the user sits in the seat with his head placed on the headrest and wears headphones.

[0066] The escaped sound waves are sound waves that overflow the ears of the listening subject of the audio to be played. In actual applications, the earphones may have different sound waves that overflow the earphones due to different models or different wearing postures of the wearers, that is, the sound leakage directions of the earphones are different, which not only include side and rear sound waves, but also include escaped sound waves in a 360° direction centered on the earphones. Regardless of the direction of the escaped sound waves, the principle of reducing the escaped sound waves is the same and falls within the protection scope of the embodiments of the present application.

[0067] As an implementable method of the embodiment of the present application, when determining the first amplitude and first phase of the escaped sound wave corresponding to the audio to be played, the following method can be used but not limited to analyze the audio to be played to determine the first amplitude and the first phase of the escaped sound wave. When the vehicle computer sends the audio to be played to the ANC headset equipped with the vehicle headrest, it will also synchronously send the audio to be played to the vehicle computing center, which will analyze the audio to be played and determine the first amplitude and the first phase of the escaped sound wave.

[0068] Step 102, setting a second amplitude and a second phase of the noise elimination wave according to the first amplitude and the first phase, wherein the first amplitude is the same as the second amplitude, and the first phase is opposite to the second phase;

[0069] The sound waves of the embodiment of the present application include escape sound waves and noise-reducing sound waves, wherein the noise-reducing sound waves are used to offset the escape sound waves to achieve the purpose of reducing the escape sound waves, thereby avoiding affecting other passengers.

[0070] In order to achieve the purpose of eliminating the escaping sound waves, it is necessary to set the noise-eliminating wave so that the second amplitude of the noise-eliminating wave needs to be the same as the first amplitude, and the second phase of the noise-eliminating wave needs to be opposite to the first phase of the escaping sound wave, thereby achieving the purpose of attenuating or eliminating the escaping sound waves.

[0071] It should be noted that, since sound waves have a certain attenuation during transmission, when setting the second amplitude and the second phase, it is ensured that the first amplitude is the same as the second amplitude when the escaping sound wave and the noise-canceling wave intersect, and the first phase is opposite to the second phase. The specific set values ​​need to be set according to different headphone models, and the embodiment of the present application does not limit this.

[0072] Step 103, controlling the second propagation direction of the noise canceling wave according to the first propagation direction of the escaping sound wave;

[0073] In this embodiment, in order to enable the escaping sound wave and the noise-cancelling wave to intersect, it is necessary to set the second propagation direction of the noise-cancelling wave in addition to setting the second amplitude and the second phase before emitting the noise-cancelling wave. It is sufficient if the second propagation direction intersects with the first propagation direction at an angle. It is not necessary that the angle between the escaping sound wave and the noise-cancelling wave when they intersect is 180°. As long as the angle between the escaping sound wave and the noise-cancelling wave is not 0, the condition for the escaping sound wave and the noise-cancelling wave to intersect can be met.

[0074] Step 104: Control the escaping sound wave and the noise canceling wave to cross each other according to the second propagation direction, so as to attenuate or eliminate the escaping sound wave.

[0075] Based on setting the second amplitude and the second phase of the noise cancellation wave in step 102 and determining the second propagation direction of the noise cancellation wave in step 103, the noise cancellation wave is emitted through a speaker so that the noise cancellation wave intersects with the escape sound wave, thereby achieving the purpose of attenuating or eliminating the escape sound wave.

[0076] The method for subtracting the escaped sound wave provided in the embodiment of the present application determines the first amplitude and the first phase of the escaped sound wave corresponding to the audio to be played, wherein the escaped sound wave is the sound wave that overflows the ear of the listening subject of the audio to be played; the second amplitude and the second phase of the noise cancellation wave are set according to the first amplitude and the first phase, respectively, the first amplitude is the same as the amplitude of the second amplitude, and the first phase is opposite to the phase of the second phase; the second propagation direction of the noise cancellation wave is controlled according to the first propagation direction of the escaped sound wave; the escaped sound wave and the noise cancellation wave are controlled to intersect according to the second propagation direction, and the escaped sound wave is attenuated or eliminated. Compared with the related art, after determining the first amplitude and the first phase of the escaped sound wave, the embodiment of the present application sets the noise cancellation wave according to the first amplitude and the first phase, so that the first amplitude is the same as the amplitude of the second amplitude, and the first phase is opposite to the phase of the second phase, and the noise cancellation wave is controlled to intersect with the escaped sound wave, and the escaped sound wave is attenuated or eliminated, thereby improving the user's driving experience.

[0077] In order to make the noise elimination wave intersect with the escape sound wave, it is necessary to first determine the second amplitude and the second phase of the noise elimination wave. The embodiment of the present application provides a method for setting the second amplitude and the second phase of the noise elimination wave according to the first amplitude and the first phase, such as Figure 3 As shown, including:

[0078] Step 201, determining the sound wave loss between the noise cancelling speaker and the sound cancelling zone, wherein the sound cancelling zone is the intersection area of ​​the escaped sound wave and the noise cancelling wave.

[0079] Since the noise cancelling waves will be absorbed or partially offset by other sound waves during the propagation process, the absorption or offset sound wave consumption needs to be considered when playing the noise cancelling waves. In order to achieve the purpose of attenuating or eliminating the escaping sound waves, the sound wave loss between the noise cancelling speaker and the silencing area should be determined first.

[0080] To better understand the silence zone, please continue to refer to Figure 2 The anechoic zone is the intersection of the escaping sound waves and the anechoic sound waves. Figure 2 The intersection of the escaping sound wave and the noise elimination wave is taken as the center of the circle and the circle formed by the preset radius is used as the silencer zone. In practical applications, the embodiment of the present application does not specifically limit the size of the preset radius and the shape of the silencer zone, and it can also be a rectangle, square, etc. containing the intersection point.

[0081] As a first implementation method of the embodiment of the present application, the sound wave loss of the noise-canceling wave can be preset in advance. In this method, the sound wave loss corresponding to the noise-canceling wave played each time is the same, and it may not be able to offset the escaped sound wave, but its processing speed is fast. As a second implementation method of the embodiment of the present application, the sound wave loss of the noise-canceling wave is calculated in real time before each noise-canceling wave is played. This method can calculate the sound wave loss based on the current environment of the vehicle and the escaped sound wave, and can offset or attenuate the escaped sound wave, or even completely offset the escaped sound wave, but the speed of calculating the sound wave loss is relatively longer than the time of the first implementation method.

[0082] Step 202: according to the acoustic wave loss, the first amplitude and the first phase, setting the second amplitude of the noise canceling wave to be the same as the first amplitude, and setting the second phase of the noise canceling wave to be opposite to the first phase.

[0083] When setting the second amplitude and the second phase of the noise canceling wave, sound wave loss is added to cancel out the escaping sound wave.

[0084] In one embodiment of the present application, when controlling the escaping sound wave and the noise cancellation wave to cross, attenuate or eliminate the escaping sound wave according to the second propagation direction, the following methods may be used but are not limited to: mixing the set noise cancellation wave through a preset codec to obtain a mixed noise cancellation wave; transmitting the mixed noise cancellation wave to a preset audio amplifier to obtain an amplified noise cancellation wave; controlling the amplified noise cancellation wave to be transmitted to a noise cancellation speaker, and controlling the noise cancellation speaker to play in the second propagation direction; controlling the escaping sound wave and the noise cancellation wave to cross in the silencing area.

[0085] For ease of understanding, Figure 4 As shown, Figure 4The schematic diagram of the flow of a kind of escaped sound wave and noise cancellation wave provided by an embodiment of the present application is shown. The vehicle computer transmits the audio to be played through a wireless transmission mode (BT-RX). After determining the second propagation direction, the second amplitude and the second phase of the noise cancellation wave based on the computing power center, the noise cancellation wave is mixed through a preset codec (such as a codec codec), and the mixed noise cancellation wave is transmitted to a preset audio amplifier (such as an AMP), power amplified in the AMP, and finally emitted through a noise cancellation speaker (such as a LANC speaker and a RANC speaker), thereby eliminating the escaped sound wave in the silencer area. The vehicle computer transmits the audio to be played to the AMP, power amplified in the AMP, and finally emitted through a speaker (such as a Lspeaker and a Rspeaker), so that the escaped sound wave is eliminated by the noise cancellation wave in the silencer area.

[0086] In the embodiment of the present application, before determining the first amplitude and the first phase of the escaped sound wave corresponding to the audio to be played, the method further includes: calibrating the escaped sound wave according to different types of headphones to obtain a mapping relationship between different open-type headphones and the corresponding escaped sound waves. When different types of headphones are worn, the directions of the corresponding escaped sound waves may be different, so when performing Figure 1 Prior to the method shown, it is necessary to complete the calibration of the escape sound waves in different types of headphones in advance and establish a mapping relationship between different open headphone types and corresponding escape sound waves, so that when the headphones are used subsequently, the corresponding escape sound waves can be found according to the type of headphones, thereby saving the time for the vehicle computer to confirm the escape sound waves.

[0087] In practical applications, the calibration method can be used to test each type of earphone in each direction (360°). If it is determined that there is overflowing sound in a certain direction, it is determined that there is escaped sound wave in that direction. The same method is used to test in each direction in turn to determine whether there is escaped sound wave. If so, a mapping relationship between the escaped sound wave in that direction and the type of earphone is established.

[0088] When parsing the audio to be played and determining the first amplitude and the first phase of the escaped sound wave, the following method may be used but is not limited to: establishing a connection with a target earphone that receives the audio to be played, where the connection may be a wireless connection or a wired connection, without specific limitation; obtaining the earphone type of the target earphone, and searching for the corresponding escaped sound wave from the mapping relationship according to the earphone type of the target earphone; parsing the audio to be played and determining the first amplitude and the first phase corresponding to the found escaped sound wave.
