[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0035] This application provides an audio playback device that can provide users with a more realistic sound effect. This will be described below with reference to the accompanying drawings.

[0036] Please see Figure 1 , Figure 1 This is a schematic diagram of a first structure of an audio playback device provided in an embodiment of this application. An embodiment of this application provides an audio playback device 100, including a first bracket 110, a plurality of first speakers 120, a second bracket 130, and a plurality of second speakers 140.

[0037] The first bracket 110 is worn on the user's head, and multiple first speakers 120 are spaced apart on the first bracket 110. The second bracket 130 is connected to the first bracket 110 and is worn on the user's shoulder. Multiple second speakers 140 are spaced apart on the second bracket 130.

[0038] Multiple first speakers 120 are spaced apart on the first bracket 110. The positions of the multiple first speakers 120 relative to the first bracket 110 can be adjusted to adjust the position of the multiple first speakers 120 relative to the user's head. The multiple first speakers 120 can form a top-side speaker array 121 for playing sounds from different directions that are above or at similar height to the ears.

[0039] Multiple second speakers 140 are spaced apart on the second bracket 130. The positions of the multiple second speakers 140 relative to the second bracket 130 can be adjusted to adjust the position of the multiple second speakers 140 relative to the user's shoulder. The multiple second speakers 140 can form a ground-side speaker array 141 for playing sounds from different directions below the ear.

[0040] It should be noted that the multiple first speakers 120 can be fixedly connected to the first bracket 110 or detachably connected. The multiple second speakers 140 can be fixedly connected to the second bracket 130 or detachably connected.

[0041] In this embodiment, a plurality of first speakers 120 are spaced apart on the first bracket 110, and a plurality of second speakers 140 are spaced apart on the second bracket 130. The first bracket 110 is worn on the user's head, and the second bracket 130 is worn on the user's shoulders. The plurality of first speakers 120 are arranged around the user's head and can provide upper surround sound. The plurality of second speakers 140 are arranged around the user's shoulders and can provide lower surround sound. The speakers are close to the user, and each speaker can correspond to one channel, so that the plurality of first speakers 120 and the plurality of second speakers 140 can output sound from different directions, thereby spatially enveloping the user's hearing range and allowing the user to experience a more realistic sound effect.

[0042] Optionally, the plurality of first speakers 120 includes at least three first speakers 120, and the at least three first speakers 120 are used to provide audio information to the user in at least three directions; and / or the plurality of second speakers 140 includes at least three second speakers 140, and the at least three second speakers 140 are used to provide audio information to the user in at least three directions.

[0043] A first support 110 is worn on the user's head, and at least three first speakers 120 are spaced apart on the first support 110 and located at different positions on the user's head to provide the user with audio information from at least three directions. A second support 130 is worn on the user's shoulder, and at least three second speakers 140 are spaced apart on the second support 130 and located at different positions on the user's shoulder to provide the user with audio information from at least three directions.

[0044] For example, the first bracket 110 may be provided with three first speakers 120 at intervals, with the three first speakers 120 located in front, middle, and back of the user's head, respectively. For example, one first speaker 120 may be located at the user's forehead; one first speaker 120 may be located near the user's ear; and one first speaker 120 may be located at the back of the user's head. The second bracket 130 may also be provided with three second speakers 140 at intervals, with the three second speakers 140 located in front, middle, and back of the user's shoulder, respectively. For example, one second speaker 140 may be located in front of the user's shoulder; one second speaker 140 may be located on the user's left or right shoulder; and one second speaker 140 may be located behind the user's shoulder.

[0045] Therefore, when the audio playback device 100 worn by the user has three first speakers 120 and three second speakers 140, the user can simultaneously perceive audio information from three different directions at similar heights or above the ears, and can also simultaneously perceive audio information from three different directions below the ears. The user can simultaneously perceive six different heights and directions of sound, thereby spatially enveloping the user's auditory range and making the user feel closer to the real experience.

[0046] For example, the first bracket 110 is provided with four first speakers 120 spaced apart, and the four first speakers 120 are respectively located in front of, behind, left of, and right of the user's head. For example, one first speaker 120 is located at the user's forehead, two first speakers 120 are respectively located near the user's left and right ears, and one first speaker 120 is located at the back of the user's head. The second bracket 130 is provided with four second speakers 140 spaced apart, and the four second speakers 140 are respectively located in front of, behind, left of, and right of the user's shoulders. For example, one second speaker 140 is located in front of the user's shoulder, two second speakers 140 are respectively located on the user's left and right shoulders, and one second speaker 140 is located behind the user's shoulder.

[0047] Therefore, when the audio playback device 100 worn by the user has four first speakers 120 and four second speakers 140, the user can simultaneously perceive audio information from four different directions at similar heights or above the ears, and can also simultaneously perceive audio information from four different directions below the ears, so that the user can simultaneously perceive sounds from eight different heights and directions.

[0048] For example, the first bracket 110 is provided with six first speakers 120 at intervals, with two first speakers 120 each at the front, middle, and back of the user's head. For example, one first speaker 120 is provided at the temples or eyebrows on both sides of the user, one first speaker 120 is provided near the ears on both sides of the user, and one first speaker 120 is provided at the back of the head on both sides of the user. The second bracket 130 is provided with six second speakers 140 at intervals, with two second speakers 140 each at the front, middle, and back of the user's shoulders. For example, one second speaker 140 is provided on each of the left and right sides in front of the user's shoulders, one second speaker 140 is provided on each of the left and right shoulders, and one second speaker 140 is provided on each of the left and right sides behind the user's shoulders.

[0049] Therefore, when the audio playback device 100 worn by the user has six first speakers 120 and six second speakers 140, the user can simultaneously perceive audio information from six different directions at similar heights or above the ears, and can also simultaneously perceive audio information from six different directions below the ears, thus allowing the user to simultaneously perceive sounds from 12 different heights and directions.

[0050] This application does not limit the number of first speakers 120 and second speakers 140. It is understood that the more first speakers 120 spaced apart on the first bracket 110 and / or the more second speakers 140 spaced apart on the second bracket 130, the more audio information at different heights and directions can be provided to the user, and the audio information can be played more precisely. With the first speakers 120 and second speakers 140 close to the user, the sound at different heights and directions surrounds the user, which can better envelop the user's hearing range in space, making the user feel closer to the real scene.

[0051] It should be noted that the number of first speakers 120 on the first bracket 110 and the number of second speakers 140 on the second bracket 130 can be the same or different. For example, there may be 4 first speakers and 6 second speakers; or 6 first speakers and 8 second speakers.

[0052] Optionally, the audio playback device 100 further includes a connecting bracket 150, which is connected between the first bracket 110 and the second bracket 130. The first bracket 110 and the second bracket 130 can be fixedly connected to the connecting bracket 150, or they can be detached. When the first bracket 110 and the second bracket 130 are detachably connected to the connecting bracket 150, the user can use only the multiple first speakers 120 on the first bracket 110 to play audio information, or only the multiple second speakers 140 on the second bracket 130 to play audio information.

[0053] Optionally, the second bracket 130 is arc-shaped and includes a first portion 131 and a second portion 132 located on both sides of the connecting bracket 150. Multiple second speakers 140 are distributed in the first portion 131 and the second portion 132. For example, when the second bracket 130 has six second speakers 140 spaced apart, the first portion 131 has three second speakers 140 spaced apart, located in front, middle, and behind the user's left shoulder, respectively. The second portion 132 also has three second speakers 140 spaced apart, located in front, middle, and behind the user's right shoulder, respectively.

[0054] Understandably, the second support 130 is curved rather than a closed ring, so that users can easily wear the second support 130 on their shoulders through the curved notch, and the curve can fit the user's shoulders more closely.

[0055] The connecting bracket 150 includes a first adjustment structure to adjust the distance between the first bracket 110 and the second bracket 130. Different users have different head sizes, therefore the height at which the first bracket 110 is worn varies, and different users also have different neck lengths. Therefore, when wearing the audio playback device 100, different users need to adjust the length of the connecting bracket 150 according to their own needs to adjust the distance between the first bracket 110 and the second bracket 130. This allows the audio playback device 100 to better match the usage needs of different users, preventing the distance between the first bracket 110 and the second bracket 130 from being too small, causing most of the weight of the audio playback device 100 to be borne by the head, and also preventing the distance from being too large, preventing the user from using the audio playback device 100 or causing most of the weight of the audio playback device 100 to be borne by the shoulders.

[0056] Optionally, the first support 110 can be adjusted in size according to the user's head circumference. For example, the first support is ring-shaped and includes a second adjustment structure to adjust the size of the first support. This application does not limit the material and structure of the first support 110, as long as it allows the user to wear it comfortably.

[0057] The audio playback device 100 can be used to play audio information from the video playback device 200. For example, the audio playback device 100 may include a wireless receiving module 160 for wirelessly connecting to the video playback device 200 and receiving audio information sent by the video playback device 200. The wireless receiving module 160 can be a Bluetooth module or a Wi-Fi module, so the audio playback device 100 can wirelessly connect to the video playback device 200 via Bluetooth or Wi-Fi to receive audio information sent by the video playback device 200.

[0058] The video playback device 200 can be, for example, a television, and includes a display module 210. The display module 210 is used to display images, and the audio information is matched with the images displayed by the video playback device 200.

[0059] For example, when the video playback device 200 displays a scene of a helicopter hovering overhead and a child shouting on the ground, the audio playback device 100 can play helicopter-related audio information through six first speakers 120 worn on the user's head in different directions, based on the real-time position of the helicopter relative to the user in the display screen. At the same time, the audio playback device 100 can also play child-related audio information through six second speakers 140 worn on the user's shoulders in different directions, based on the real-time position of the child relative to the user in the display screen, so that the user can hear the sound of the helicopter hovering overhead and the sound of the child shouting around them as if they were there.

[0060] When the audio playback device 100 is equipped with six first speakers 120 located at the user's head and six first speakers 120 located at the user's shoulders, it can provide the user with a surround sound field from 12 directions. Compared with the prior art, where the user receives most of the sound from the front, the embodiments of this application can provide the user with sound from high places, low places, front, back, left, right and different angles, which can provide the user with an immersive and realistic sound effect.

[0061] It should be noted that the video playback device 200 may also play audio information without displaying a video.

[0062] Please see Figure 2 , Figure 3 and Figure 4 , Figure 2 This is a schematic diagram of a second structure of the audio playback device provided in an embodiment of this application. Figure 3 This is a schematic diagram of the structure of the video playback device provided in the embodiments of this application. Figure 4 This is a schematic diagram of the structure of a playback system provided in an embodiment of this application. This application also provides a playback system 300, which includes a video playback device 200 and an audio playback device 100.

[0063] The video playback device 200 includes a display module 210 and a wireless transmission module 220. The display module 210 displays the screen, and the wireless transmission module 220 can be a Bluetooth module or a WIFI module, so that the video playback device 200 can send audio information matching the display screen to the audio playback device 100 via Bluetooth or WIFI.

[0064] The audio playback device 100 can be any of the audio playback devices described in the above embodiments. The audio playback device 100 may include a wireless receiving module 160, which is used to receive audio information from the video playback device 200. The wireless receiving module 160 may be a Bluetooth module or a WIFI module, so that the audio playback device 100 can wirelessly connect to the video playback device 200 via Bluetooth or WIFI to receive audio information sent by the video playback device 200.

[0065] The audio playback device 100 includes a first support 110 worn on the head and a second support 130 worn on the user's shoulder. The first support 110 has a plurality of first speakers 120 spaced apart, for example, the plurality of first speakers 120 forming a top-side speaker array 121. The second support 130 has a plurality of second speakers 140 spaced apart, for example, the plurality of second speakers 140 forming a ground-side speaker array 141. At least one of the plurality of first speakers 120 in the top-side speaker array 121 and the plurality of second speakers 140 in the ground-side speaker array 141 plays audio information.

[0066] Please continue to refer to this. Figure 2 The audio playback device 100 may further include a power amplifier group 170, such as a top-side power amplifier group 171 for driving a plurality of first speakers 120, and a ground-side power amplifier group 172 for driving a plurality of second speakers 140. The plurality of first speakers 120 constitute a top-side speaker array 121, and the plurality of second speakers 140 constitute a ground-side speaker array 141. The power amplifier in the top-side power amplifier group 171 may be one or more. For example, the power amplifier in the top-side power amplifier group 171 may correspond one-to-one with the first speakers 120 in the top-side speaker array 121; or, for example, one power amplifier in the top-side power amplifier group 171 may correspond to two or more first speakers 120 in the top-side speaker array 121. The power amplifier in the ground-side power amplifier group 172 may also be one or more. For example, the power amplifier in the ground-side power amplifier group 172 can correspond one-to-one with the second speaker 140 in the ground-side speaker array 141; or, for another example, one power amplifier in the ground-side power amplifier group 172 can also correspond to two or more second speakers 140 in the ground-side speaker array 141.

[0067] The audio playback device 100 may also include a battery management module 180 for providing power so that the audio playback device 100 can operate normally.

[0068] The audio playback device 100 may also include a processor 190. When the audio playback device 100 receives the audio information from the video playback device 200, the processor 190 needs to decode the audio information, identify multiple channel identifiers in the audio information, and the audio information includes multiple channel identifiers, which means that the audio information includes multiple channels. The audio information is divided into multiple sub-audio information of different channels according to the multiple channel identifiers.

[0069] Multiple first speakers 120 and multiple second speakers 140 are used to play sub-audio information of different channels, that is, each speaker corresponds to playing sub-audio information of one channel. Therefore, the processor 190 can determine the multiple target speakers corresponding to the multiple sub-audio information to be played according to the channel identifier.

[0070] The processor 190 controls the antenna power amplifier group 171 and the ground power amplifier group 172 to drive the antenna speaker array 121 and the ground speaker array 141 respectively, thereby using multiple target speakers to play different sub-audio information.

[0071] In this embodiment, multiple first speakers 120 and multiple second speakers 140 respectively play sub-audio information of different channels. The top-side speaker array 121 can generate 360° upper surround sound, and the ground-side speaker array 141 can generate 360° lower surround sound, thereby spatially enveloping the user's hearing range, presenting a stereo effect, and providing the user with a more realistic sound effect as if they were there.

[0072] Optionally, the audio playback device 100 may also have a volume control module, allowing users to adjust the volume without the hassle of using a remote control. When users wear the audio playback device 100 to listen to audio from the video playback device 200, they can not only experience immersive sound effects but also enjoy unrestricted listening regardless of position or posture.

[0073] Please see Figure 5 , Figure 5 This is a schematic flowchart of a first embodiment of an audio playback method provided in this application, applied to an audio playback device. The audio playback device includes a first bracket for wearing on a user's head; a plurality of first speakers spaced apart from the first bracket; a second bracket connected to the first bracket for wearing on the user's shoulders; and a plurality of second speakers spaced apart from the second bracket. For example, the audio playback device may include six first speakers surrounding the user's head and six second speakers surrounding the user's shoulders.

[0074] In 101, when audio information sent by a video playback device is received, multiple channel identifiers in the audio information are identified.

[0075] In 102, the audio information is divided into multiple sub-audio information based on multiple channel identifiers, and different sub-audio information corresponds to different channel identifiers.

[0076] The audio playback device may include a wireless receiving module for wirelessly connecting to the video playback device and for receiving audio information sent by the video playback device.

[0077] When audio information is received from a video playback device, the audio information is decoded, and multiple channel identifiers in the audio information are identified. If multiple channel identifiers are identified, it means that the audio information includes multiple channels. Therefore, the audio information can be divided into multiple sub-audio information of different channels based on the multiple channel identifiers.

[0078] For example, the audio information is identified by six channel identifiers, so the audio information can be divided into six different channel sub-audio information. Different channels correspond to different sound directions, so the six different channel sub-audio information correspond to different sound directions, such as: top front left, top middle right, top back left, bottom front right, bottom middle left, and bottom back left. These sound directions also include height information.

[0079] In 103, multiple first speakers and multiple second speakers are used to play different sub-audio information.

[0080] After dividing the audio information into multiple sub-audio information based on multiple channel identifiers, different sub-audio information is played using multiple first speakers and multiple second speakers respectively.

[0081] Specifically, the target speaker can be determined from multiple first speakers and multiple second speakers based on the sound direction corresponding to the channel to which each sub-audio information belongs.

[0082] For example, if the current audio information is divided into 6 sub-audio information, and the sound directions of the channels to which the 6 audio information belongs are: top front left, top center right, top rear left, bottom front right, bottom center left, and bottom rear left, then the 3 first speakers in the top-side speaker array of the audio playback device located at top front left, top center right, and top rear left, and the 3 second speakers in the ground-side speaker array located at bottom front right, bottom center left, and bottom rear left will respectively play the 6 sub-audio information, so the sound heard by the user can come from 6 different directions.

[0083] For example, in the next moment, the audio information is divided into 12 sub-audio information. The sound directions of the channels to which the 12 audio information belong are: upper front left, upper front right, upper center right, upper center left, upper rear left, upper rear right, lower front right, lower front left, lower center left, lower center right, lower rear left, and lower rear right. Then, the six first speakers in the top-side speaker array of the audio playback device located at upper front left, upper front right, upper center right, upper center left, upper rear left, and upper rear right, and the six second speakers in the ground-side speaker array located at lower front right, lower front left, lower center left, lower center right, lower rear left, and lower rear right, will respectively play the 12 sub-audio information. Thus, the sound heard by the user can come from 12 different directions.

[0084] For example, if the video playback device displays a lively party scene with sounds of adults, children, pets, and toys coming from all directions, such as upstairs, downstairs, in front, behind, left, and right, then the user can clearly distinguish the direction from which each sound is coming by wearing an audio playback device.

[0085] For example, the video playback device displays a scene with a helicopter and children. Through the six first speakers worn on the user's head (top front left, top front right, top middle right, top middle left, top rear left, and top rear right), the user can hear the sound of the helicopter hovering overhead. Through the six second speakers worn on the user's shoulders (bottom front right, bottom front left, bottom middle left, bottom middle right, bottom rear left, and bottom rear right), the user can hear the sound of children running and playing around them.

[0086] Therefore, the audio playback device of this application embodiment includes multiple first speakers surrounding the user's head and multiple second speakers surrounding the user's shoulders. The received audio information is divided into sub-audio information of different channels according to the channel identifier. The multiple first speakers and multiple second speakers play different sub-audio information respectively. The multiple first speakers are located in different directions of the user's head and the multiple second speakers are located in different directions of the user's shoulders, which increases the precision of the audio information playback, thereby spatially enveloping the user's hearing range and achieving a very good sound positioning effect, making the user feel closer to the real scene.

[0087] Please see Figure 6 , Figure 6 This is a second flowchart illustrating an audio playback method provided in an embodiment of this application, applied to an audio playback device, which includes a plurality of first speakers surrounding the user's head and a plurality of second speakers surrounding the user's shoulders.

[0088] For example, an audio playback device may include six first speakers surrounding the user's head and six second speakers surrounding the user's shoulders.

[0089] In step 201, audio information sent by the video playback device is received.

[0090] When a user needs to use the audio playback device, they can turn it on and wait for it to connect to the video playback device. The audio playback device may include a wireless receiving module, such as a Bluetooth receiving module. The video playback device may also include a wireless transmitting module, such as a Bluetooth transmitting module; for example, the video playback device could be a television. Therefore, the audio playback device can wirelessly connect to the video playback device's Bluetooth transmitting module via its Bluetooth receiving module.

[0091] If the audio playback device and the video playback device establish a wireless connection, the video playback device can send audio information to the audio playback device via a Bluetooth transmitting module, and the audio playback device can receive the audio information via a Bluetooth receiving module. The video playback device includes a display module for displaying images, and the audio information is matched with the displayed images.

[0092] In step 202, when the channel identifiers in the audio information are identified as left channel identifier and right channel identifier, the audio information is processed to obtain audio information with at least three channel identifiers.

[0093] When an audio playback device receives audio information, it can identify the format standard of the audio information to determine whether the audio information contains a multi-channel identifier.

[0094] If the audio information is identified as having only left and right channel identifiers, meaning the audio playback device receives ordinary audio information with only left and right channels, then the audio information needs to be processed. For example, AI audio and video technology can be used to extract and process the audio information from the left and right channels into audio information with at least three channel identifiers. This means processing audio information with only left and right channels into audio information with at least three channels, such as 6, 8, or 12 channels. This allows the audio playback device to work with multiple first and second speakers to play the audio information, enabling users to hear sounds from more directions and creating a simulated spatial surround sound effect.

[0095] If the received audio information is identified as multi-channel audio information, that is, the audio information format standard already supports multi-channel spatial surround sound, such as Dolby Atmos, then there is no need to use AI audio and video technology to extract and process the received audio information.

[0096] It should be noted that if the audio information is identified as mono, AI audio and video technology can be used to extract and process the mono audio information into multi-channel audio information.

[0097] In 203, multiple channel identifiers in the audio information were identified.

[0098] In 204, the audio information is divided into multiple sub-audio information based on multiple channel identifiers, and different sub-audio information corresponds to different channel identifiers.

[0099] When audio information is received from a video playback device, the audio information is decoded, and multiple channel identifiers are identified. If multiple channel identifiers are identified, it means that the audio information includes multiple channels. Therefore, the audio information can be divided into multiple sub-audio information of different channels based on the multiple channel identifiers.

[0100] For example, the audio information is identified by six channel identifiers, so the audio information can be divided into six sub-audio information of different channels. Different channels correspond to different sound directions, and the six sub-audio information of different channels correspond to different sound directions, such as: top front left, top middle right, top back left, bottom front right, bottom middle left, and bottom back left. These sound directions also include height information.

[0101] In 205, multiple first speakers and multiple second speakers are used to play different sub-audio information respectively.

[0102] After dividing the audio information into multiple sub-audio information based on multiple channel identifiers, different sub-audio information is played using multiple first speakers and multiple second speakers respectively.

[0103] Specifically, the target speaker can be determined from multiple first speakers and multiple second speakers based on the sound direction corresponding to the channel to which each sub-audio information belongs.

[0104] For example, if the current audio information is divided into 12 sub-audio information, and the sound directions of the channels to which the 12 audio information belong are: upper front left, upper front right, upper center right, upper center left, upper rear left, upper rear right, lower front right, lower front left, lower center left, lower center right, lower rear left, and lower rear right, then the 6 first speakers in the top-side speaker array of the audio playback device located at upper front left, upper front right, upper center right, upper center left, upper rear left, and upper rear right, and the 6 second speakers in the ground-side speaker array located at lower front right, lower front left, lower center left, lower center right, lower rear left, and lower rear right, will all correspond to playing the 12 sub-audio information respectively. In this way, the sound heard by the user can come from 12 different directions. As a result, users can not only perceive audio information from six different directions above or at similar height to their ears, but also from six different directions below their ears. The sounds heard by users come from all directions, and the sounds from each direction surround the user. Different sounds also have different height information, thus providing users with an immersive sound experience.

Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
