[0034] With the increasing popularity of home theater systems, users' demand for multi-channel audio experiences is constantly rising. However, in practical applications, the installation and configuration of traditional home theater speakers is usually quite complex. It involves not only the allocation and connection of multiple audio channels but also the pairing and layout setup of each speaker individually, making the process cumbersome, error-prone, and severely impacting the user experience. Therefore, there is an urgent need to provide a simpler and more efficient multi-channel audio configuration solution to improve system usability and deployment efficiency.

[0035] Based on this, embodiments of this application provide a multi-channel Bluetooth audio decoder and a multi-Bluetooth home theater device. This addresses the problems of cumbersome pairing of home theater speakers, complex channel configuration, and inconvenient user operation. See below for details.

[0036] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0037] Please see Figure 1 This application provides a multi-channel Bluetooth audio decoder, which includes a housing assembly 10, a decoding main control assembly 11, multiple Bluetooth transmitting assemblies 12, and multiple pairing trigger buttons 13. The following is a detailed description:

[0038] The housing assembly 10 is used to encapsulate the decoding main control assembly 11 and the Bluetooth transmitting assembly 12 as a whole, and provides physical support and protection. In some embodiments, its surface is provided with an interface area and an operation panel to facilitate user operation and component replacement.

[0039] The decoding main control component 11, installed within the housing component 10, is used to parse the input audio data and output multiple audio channel signals. The decoding main control component 11 may include a processing chip, a power supply component, and interface circuitry, and is compatible with various input audio formats (such as HDMI, optical fiber, etc.). In some embodiments, the decoding main control component 11 can also automatically allocate and switch output channel signals, improving device compatibility and adaptability. Specifically, the audio data may include, but is not limited to: multi-channel audio signals (such as stereo, 5.1 channel, 7.1 channel, etc.), immersive audio signals based on sound field modeling (such as Ambisonics format), and spatial audio formats based on audio objects (such as Dolby Atmos).

[0040] Multiple Bluetooth transmitting components 12 are installed within the housing component 10 and connected to the decoding master control component 11 respectively. Each Bluetooth transmitting component 12 receives audio channel signals output by the decoding master control component 11. Each Bluetooth transmitting component 12 corresponds to one or more audio channel signals and transmits the audio channel signal corresponding to that Bluetooth transmitting component 12 to one or more Bluetooth speakers 20 via a preset Bluetooth protocol. Specifically, the preset Bluetooth protocol may include A2DP (Advanced Audio Distribution Profile), LC3 (Low Complexity Communication Codec), BIS (Broadcast Isochronous Stream), etc. In one embodiment, if the Bluetooth speaker 20 is a dual-channel (stereo) speaker, the Bluetooth transmitting component 12 can be controlled to transmit two audio channel signals to the Bluetooth speaker 20, such as left front channel + right front channel, or left surround channel + right surround channel.

[0041] In this embodiment, each audio channel signal can be wirelessly transmitted through one or more Bluetooth transmitting components; a single Bluetooth transmitting component can also correspond to one or more audio channel signals, and an audio channel signal can also be transmitted simultaneously by multiple Bluetooth transmitting components to support flexible deployment in large spaces or multi-speaker scenarios.

[0042] Specifically, a single audio channel can correspond to multiple Bluetooth speakers. For example, in a cinema environment, to enhance sound field coverage and surround sound, a single channel signal can be simultaneously transmitted to two or more Bluetooth speakers located in the same area. Conversely, multiple audio channels can also share a single Bluetooth transmitter for unified transmission, enabling flexible configuration and reuse of transmission resources. In this embodiment, audio channels and Bluetooth transmitters can be freely combined and mapped, not limited to a fixed number of Bluetooth transmitters corresponding to the traditional number of channels (such as 5.1 or 7.1 channels), and can be dynamically adjusted according to the actual speaker layout and sound field requirements.

[0043] In some embodiments, in a partial audio playback configuration, the decoding master control component 11 can also superimpose the audio signal corresponding to the low-frequency effect channel (LFE) onto one or more audio channel signals through a mixing method, so as to adapt to the speaker configuration without an independent subwoofer to realize the restoration and playback of low-frequency signals.

[0044] Specifically, the output parameters of each audio channel signal can be adjusted independently, including: volume adjustment, used to control the playback intensity of each channel and improve the overall audio balance; phase adjustment, used to correct phase shifts caused by speaker placement or hardware differences and ensure synchronous sound output of multiple channels; delay adjustment, used to compensate for differences in speaker spacing and improve the temporal consistency of listening position; and frequency response adjustment, which can set the enhancement or attenuation of specific frequency bands based on filter parameters to achieve equalization processing of the audio signal spectrum.

[0045] Multiple pairing trigger buttons 13 are disposed on the surface of the housing assembly 10. Each pairing trigger button 13 corresponds one-to-one with a Bluetooth transmitter assembly 12, and is used to trigger the corresponding Bluetooth transmitter assembly 12 to enter pairing mode. Users can select the number of Bluetooth transmitter assemblies 12 to trigger pairing based on the number of Bluetooth speakers 20 to be paired. Specifically, the pairing trigger buttons 13 can be physical buttons or touch-sensitive switches, improving the user's control efficiency over the connection status of multiple speakers and avoiding problems such as repeated pairing or signal confusion.

[0046] This application's multi-channel Bluetooth audio decoder integrates the decoding main control component 11 with multiple Bluetooth transmitting components 12, and performs pairing of each channel with the pairing trigger button 13, thereby achieving independent Bluetooth transmission of audio data. This alleviates the problems of complex speaker layout adjustment, complex pairing, cumbersome operation, and easy errors in existing home theater systems, and improves the installation flexibility and user convenience of the multi-channel audio system.

[0047] In an optional embodiment, the housing assembly 10 is provided with a USB connection port, and the Bluetooth transmitter assembly 12 is pluggably connected to the decoding main control assembly 11 via the USB connection port. This pluggable connection structure allows users to flexibly add or remove Bluetooth transmitter assemblies 12 according to the actual number of audio channels required during use, enhancing the scalability and maintenance convenience of the decoder. Simultaneously, this structure facilitates standardized production and subsequent upgrades and modifications, reducing maintenance costs and lowering the barrier to entry. In practical applications, when a Bluetooth transmitter assembly 12 malfunctions, the user does not need to return the entire unit for repair or disassembly; they only need to unplug the damaged Bluetooth transmitter assembly 12 and replace it. Furthermore, this modular design also facilitates future support for more Bluetooth transmission standards or transmitter assemblies with different power levels, achieving compatibility expansion in various scenarios.

[0048] In an optional embodiment, the multi-channel Bluetooth audio decoder further includes multiple indicator lights 14, each corresponding to one Bluetooth transmitter component 12. The indicator lights 14 are mounted on the surface of the housing component 10 and positioned above their corresponding Bluetooth transmitter components 12, displaying the connection status of the corresponding Bluetooth transmitter component 12. These indicator lights 14 visually reflect the current operating status of each Bluetooth transmitter component 12, such as: no light when not paired, flashing light during connection, green light on successful connection, and red light on failed connection. Users can quickly ascertain the system connection status without external devices, enhancing the user experience. In practice, users can determine whether each speaker is correctly connected to its corresponding channel based on the color or flashing status of the indicator lights 14, avoiding incorrect or missed connections and improving the installation efficiency and stability of the home theater system.

[0049] In an optional embodiment, the multi-channel Bluetooth audio decoder further includes a mode switching component 15 disposed on the surface of the housing component 10, used to switch the mapping method between the audio channel signal and the multiple Bluetooth transmitting components 12. In the case that the decoding master control component 11 is in default mode, each Bluetooth transmitting component 12 corresponds to an audio channel signal and is used to transmit the audio channel signal corresponding to the Bluetooth transmitting component 12 to a Bluetooth speaker 20 through a preset Bluetooth protocol.

[0050] Specifically, the mode switching component 15 may include a knob to switch to the corresponding mode according to the rotation angle of the knob.

[0051] In one embodiment, the mode switching component 15 can also switch the decoding master control component 11 to a first mode and a second mode. Specifically, the first mode can be: the first Bluetooth transmitting component corresponds to the left front channel and the right front channel; the second Bluetooth transmitting component corresponds to the left surround channel and the left rear surround channel; and the third Bluetooth transmitting component corresponds to the right surround channel and the right rear surround channel. The second mode can be: the first Bluetooth transmitting component corresponds to the left front channel and the left surround channel; the second Bluetooth transmitting component corresponds to the right front channel and the right surround channel; and the third Bluetooth transmitting component corresponds to the left rear surround channel and the right rear surround channel.

[0052] Users can quickly switch between the preset first and second connection modes without having to manually pair them one by one.

[0053] In one embodiment, the mode switching component 15 can also switch the decoding master control component 11 to manual mode. In this mode, the user can manually pair any Bluetooth transmitter component 12 with any Bluetooth speaker 20, which is convenient for the user to adjust according to their custom needs.

[0054] In one optional embodiment, the plurality of Bluetooth transmitting components 12 includes eight Bluetooth transmitting components, which are respectively used to correspond to the left front channel, right front channel, center channel, bass channel, left surround channel, right surround channel, left rear surround channel, and right rear surround channel. Specifically, the Bluetooth transmitting components can also switch to correspond to multiple channels according to the mode.

[0055] Specifically, the multi-channel Bluetooth audio decoder in this application supports various audio configurations, including but not limited to 5.1 and 7.1 channel systems. In 5.1 channel mode, the system can provide five audio channel signals (front left, front right, center, rear left, and rear right) and one subwoofer channel, meeting the audio needs of common home theater systems. In 7.1 channel mode, two additional surround rear channels are added, making the audio experience richer and more immersive. Users can also easily select the desired channel configuration through the mode switching component, further enhancing flexibility and applicability.

[0056] In an optional embodiment, the decoding master control component 11 further includes an energy-saving control component 16, which is installed inside the housing component 10. The energy-saving control component 16 is electrically connected to the decoding master control component 11. When all Bluetooth transmitting components 12 meet predetermined conditions, the energy-saving control component 16 controls the decoder to enter a low-power state.

[0057] The energy-saving control component 16 actively reduces power consumption when the device is idle, thereby improving overall energy efficiency and extending the device's lifespan. Specifically, the predetermined conditions can be conditions such as all Bluetooth transmitting components 12 being disconnected, no audio signal input for a long time, or being in standby mode. When these conditions are detected, the energy-saving control component 16 can control the decoding main control component 11 and related circuits to enter a sleep or low-power state, avoiding the continuous output of unnecessary power consumption.

[0058] In an optional embodiment, the decoding master control component 11 further includes a location information detection component 17, which is installed inside the housing component 10. The location information detection component 17 is electrically connected to the decoding master control component 11. The location information detection component 17 is used to detect the location information of the Bluetooth speaker 20 that is connected to the Bluetooth transmitter component 12. The decoding master control component 11 is used to output a corresponding audio channel signal to the Bluetooth transmitter component 12 according to the location information of the Bluetooth speaker 20.

[0059] By setting up the location information detection component 17, the multi-channel Bluetooth audio decoder can automatically allocate audio channels based on the actual position of each speaker in the space when multiple Bluetooth speakers 20 are connected. For example, when a Bluetooth speaker 20 is identified as being located in the area slightly to the left in front of the user, it can be automatically assigned a left front channel signal, thereby achieving a more realistic spatial sound effect reproduction and enhancing the user's immersive audio-visual experience.

[0060] When the decoding main control component 11 is not located in the central area, the position information detection component 17 can also obtain the corresponding position information by comparing the relative positions of multiple Bluetooth speakers 20.

[0061] Specifically, the location information detection component 17 includes a signal transmitter 171 and a signal receiver 172. The signal transmitter 171 is used to emit a positioning signal. The multi-channel Bluetooth audio decoder also includes a signal reflector 175, which is installed on the Bluetooth speaker 20 and is used to reflect the positioning signal emitted by the signal transmitter 171 to the signal receiver 172.

[0062] The decoding main control component 11 can perform triangulation or other forms of spatial positioning on the position of each Bluetooth speaker 20 based on the signal propagation path and time difference between the signal transmitter 171 and the signal receiver 172, combined with the feedback characteristics of the signal reflector 175, so as to determine the relative coordinates or orientation of the speaker.

[0063] In other embodiments, the location information detection component 17 may also obtain the location information of the Bluetooth speaker 20 through other means such as infrared sensing and manual positioning. These methods may also coexist with the signal transmitter 171, the signal receiver 172, and the signal reflector 175.

[0064] This application also provides a multi-Bluetooth home theater device, including a multi-channel Bluetooth audio decoder as described in any of the preceding claims.

[0065] Bluetooth home theater devices can also include a display screen and a main control unit. The main control unit is used to connect audio providing devices (such as mobile phones and computers), the display screen, and multi-channel Bluetooth audio decoders, thereby enabling unified access to multi-source audio content, multi-channel decoding, wireless distribution of audio signals, and synchronized playback with video content.

[0066] This home theater device allows users to easily build a home theater system that supports multi-channel wireless audio output, achieving high-fidelity, low-latency surround sound without complex wiring. Simultaneously, the main control unit integrates playback control, device management, and sound field adjustment functions, providing a visual interactive interface with a display screen to further enhance the user experience. This device is suitable for various usage scenarios, such as family living rooms, small home theaters, or smart home multimedia centers, and boasts excellent scalability and compatibility.

Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this application.

[0069] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0070] It should also be noted that the above are merely preferred embodiments of this application and do not limit the scope of patent protection of this application.
