Description

Technical Field

[0001] This invention relates to the field of media player technology, and more particularly to a combined stereo multi-channel Bluetooth speaker. Background Technology

[0002] Bluetooth speakers, as portable audio playback devices, are widely popular in the consumer electronics market due to their advantages such as wireless connectivity, compact size, and ease of use. As users' demands for sound quality and listening experience continue to rise, Bluetooth speakers with stereo or even multi-channel playback capabilities are gradually becoming the mainstream demand in the market.

[0003] Currently, Bluetooth speakers on the market that achieve multi-channel stereo playback mainly adopt an integrated multi-unit structure. These products integrate multiple independent speaker units into a single housing, using built-in digital signal processing technology to enhance the audio signal with virtual surround sound or stereo to simulate multi-channel playback. However, due to the limitations of their integrated physical structure, these products generally suffer from the following shortcomings in practical use: 1. The orientation and relative spatial position of each speaker unit are fixed at the factory, and users cannot flexibly adjust them according to the layout of the actual listening environment or the location of the listeners. As a result, in areas away from the front of the speakers, high-frequency details are significantly attenuated, sound image positioning is blurred, and there are significant differences in sound quality perception and sound field consistency between different listening positions.

[0004] 2. All speaker units are confined to the same enclosure, making it impossible to use any single speaker unit independently. In listening scenarios with multiple users and multiple areas (such as family gatherings, outdoor camping, or office cubicles), the volume intensity and sound field immersion perceived by users closer to the speaker are significantly different from those farther away, making it difficult to achieve a balanced and unified listening experience throughout the entire space.

[0005] Therefore, how to maintain the portability and integration of Bluetooth speakers while giving them the ability to flexibly deploy speaker units with adjustable physical positions and the ability to separate or combine them, and simplify the resulting signal transmission and power management operations, has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] The purpose of this invention is to solve the problems existing in the prior art and to propose a combined stereo multi-channel Bluetooth speaker.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A combined stereo multi-channel Bluetooth speaker includes a speaker body, multiple module Bluetooth speakers and a Bluetooth control module. The speaker body and the multiple module Bluetooth speakers are detachably combined via a combination bracket. The module Bluetooth speakers transmit signals and are charged through a touch-sensitive communication module on the combination bracket. The main body of the speaker includes two main end seats symmetrically arranged at both ends. The back of the main end seat is provided with a speaker end cover. The main player is arranged inside the main end seat. The main end seat is provided with a combination adjustment component for controlling the translation of the combination bracket. The combined bracket includes a combined support column disposed between two main end seats. The combined support column is configured with multiple combined areas according to the number of module Bluetooth speakers, which are used to realize the signal transmission and charging of each individual module Bluetooth speaker. The touch-sensitive communication module is disposed in each combined area of ​​the combined support column. The module Bluetooth speaker includes an adjustable storage base, which is snapped into a combination support column. The adjustable storage base has a built-in Bluetooth player connected via a twist connector.

[0008] As a preferred embodiment, one side of the adjustable storage base is connected to a connecting seat via a damping pivot. The connecting seat has a connecting assembly port that is compatible with the combination support column, enabling assembly and disassembly. A locking port is provided on the side wall of the adjustable storage base away from the connecting assembly port.

[0009] As a preferred embodiment, the touch-sensitive communication module includes a signal contact groove disposed on the outer wall of the combined support column, and a signal contact strip disposed on the inner wall of the connecting assembly port that contacts the signal contact groove. When the connecting seat is combined and connected with the combined support column, the signal contact strip contacts the signal contact groove.

[0010] As a preferred embodiment, the torsion connector includes an outer frame connected to a Bluetooth player, an adjustable storage base with a torsion storage opening, a torsion groove on the outer side wall of the outer frame, a torsion guide post on the inner wall of the torsion storage opening that cooperates with the torsion groove, and the bottom of the outer frame connected to the inner wall of the torsion storage opening by a contact spring.

[0011] As a preferred embodiment, the combined adjustment component includes a mounting cavity formed in the main end seat, the inner wall of the mounting cavity having a limiting slide opening that penetrates the side wall, and both ends of the combined support extending into the mounting cavity through the limiting slide opening and being slidably connected to the inner wall of the mounting cavity by a telescopic spring.

[0012] As a preferred embodiment, the inner wall of the mounting cavity is connected to an adjusting gear via an adjusting shaft, and the outer walls of the combined support columns on both sides are fitted with adjusting rings. The side walls of the adjusting rings are connected to opposing racks that mesh with the adjusting gears. The spacing between the combined support columns on both sides is adjusted by rotating the adjusting shaft.

[0013] As a preferred embodiment, the speaker end cover is provided with a main energy storage unit, the connector is provided with a module energy storage unit, and the speaker body is provided with an external power supply line that supplies power to the main energy storage unit and the module energy storage unit.

[0014] As a preferred embodiment, the Bluetooth control module includes a connection status detection unit, an audio signal switching unit, and a Bluetooth transceiver disposed within the speaker body; The audio signal switching unit is electrically connected to the connection status detection unit, the touch connection module and the Bluetooth transceiver respectively. The connection status detection unit is used to detect whether the module Bluetooth speaker has established a physical electrical connection with the combined bracket through the touch connection module; In response to the connection status detection unit detecting that the module Bluetooth speaker and the combination bracket have established a physical electrical connection, the audio signal switching unit switches the audio signal transmission path to the touch-sensitive communication module for wired transmission. In response to the connection status detection unit detecting that the module Bluetooth speaker is disconnected from the combined bracket, the audio signal switching unit switches the audio signal transmission path to the Bluetooth transceiver for wireless transmission.

[0015] As a preferred embodiment, the connection status detection unit includes a Hall sensor, which is disposed within the combined support column and is triggered by sensing a magnet disposed within the module's Bluetooth speaker.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, through the combined design of a bracket, adjustable components, and an adjustable storage base, allows multiple modular Bluetooth speakers to be compactly stored on the main speaker body to form an integrated portable form, while also being able to be quickly disassembled and independently deployed in various locations. The structural design with adjustable spacing between the combined support columns and rotatable angles of the modular speakers gives the speaker units a high degree of adjustability in physical position and sound direction, solving the technical problem of traditional integrated speakers having a fixed sound field and being unable to adapt to changing listening environments.

[0017] 2. This invention provides three working modes: standalone playback, integrated playback, and split playback, each adapted to different usage scenarios. In standalone playback mode, the product is compactly stored, making it convenient for personal desktop use and portability. In integrated playback mode, the directional angle of each module speaker can be independently adjusted to form a customized multi-channel array, enhancing the near-field stereo effect. In split playback mode, multiple module speakers can be distributed around the room to create a realistic physical surround sound field. A single product can cover diverse listening scenarios from personal entertainment to group sharing, significantly improving the product's functional integration and scenario adaptability.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] Example, refer to Figures 1 to 9 A combined stereo multi-channel Bluetooth speaker includes a speaker body, multiple module Bluetooth speakers and a Bluetooth control module. The speaker body and multiple module Bluetooth speakers are detachably combined through a combination bracket. The module Bluetooth speakers transmit signals and charge through a touch-connect module on the combination bracket. It should be noted that when the modular Bluetooth speaker is in its combined state, a stable and reliable wired connection can be established between the module and the main speaker via touch, ensuring high-quality audio signal transmission and simultaneous charging management, simplifying the user's operation process. Furthermore, the detachable combination design gives the speaker system a high degree of flexibility, allowing users to separate the modular Bluetooth speaker as needed, thus achieving free switching from an "all-in-one speaker" to a "distributed multi-channel speaker".

[0024] The Bluetooth control module includes a connection status detection unit, an audio signal switching unit, and a Bluetooth transceiver, all located within the speaker body. The audio signal switching unit is electrically connected to the connection status detection unit, the touch-sensitive communication module, and the Bluetooth transceiver, respectively. The connection status detection unit is used to detect whether the module Bluetooth speaker establishes a physical electrical connection with the combined bracket by touching the connection module; the connection status detection unit includes a Hall sensor, which is set inside the combined support column 4 and is triggered by sensing a magnet set inside the module Bluetooth speaker.

[0025] In response to the connection status detection unit detecting that the module Bluetooth speaker and the combination bracket have established a physical electrical connection, the audio signal switching unit switches the audio signal transmission path to the touch-connection module for wired transmission. In response to the connection status detection unit detecting that the module Bluetooth speaker has disconnected from the combination bracket, the audio signal switching unit switches the audio signal transmission path to the Bluetooth transceiver for wireless transmission.

[0026] The advantage of using the above-mentioned Bluetooth control module is that, through the cooperation of the Hall sensor and the connection status detection unit, the system can automatically sense the connection and disconnection status of the Bluetooth speaker module and trigger the audio signal switching unit to complete the seamless switching between wired and wireless transmission paths. This design eliminates the tedious steps of manual pairing and switching audio sources for users, and realizes a smart interactive experience of "plug and play, unplug and connect".

[0027] Meanwhile, using wired transmission in the combined state can effectively avoid the delay and compression loss that may exist in wireless transmission, ensuring the purity of sound quality and the accuracy of sound field positioning when playing multi-channel synchronously.

[0028] The main body of the speaker includes two main end seats 1 symmetrically arranged at both ends. The back of the main end seat 1 is provided with a speaker end cover 2. The main player 3 is arranged inside the main end seat 1. The main end seat 1 is provided with a combination adjustment component for controlling the combination bracket to move horizontally. The advantages of adopting a symmetrical main end bracket 1 design are: the two main end brackets 1 provide a stable support base for the combination bracket, while the internal integrated combination adjustment components allow users to flexibly adjust the spacing of the combination bracket according to the actual number of connected Bluetooth speaker modules, improving the product's compatibility with different numbers of modules and space utilization.

[0029] Furthermore, the combined adjustment component includes a mounting cavity opened in the main end seat 1. The inner wall of the mounting cavity is provided with a limiting slide 16 that penetrates the side wall. Both ends of the combined support column 4 extend into the mounting cavity through the limiting slide 16 and are slidably connected to the inner wall of the mounting cavity through a telescopic spring 17. Both ends of the telescopic spring 17 are provided with spring plates. The spring plate connected to the combined support column 4 is fixedly connected, while the spring plate connected to the inner wall of the mounting cavity is slidably set. This setting can ensure the resistance force of the telescopic spring 17 during the relative sliding process of the combined support column 4. The inner wall of the mounting cavity is connected to an adjusting gear 19 via an adjusting shaft 18. An adjusting collar 20 is fitted on the outer wall of the combined support column 4 on both sides. The side wall of the adjusting collar 20 is connected to a relative rack 21 that meshes with the adjusting gear 19. The spacing of the combined support column 4 on both sides is adjusted by rotating the adjusting shaft 18.

[0030] When it is necessary to adjust the combined support column 4, the adjusting shaft 18 at the top is rotated to make the adjusting gear 19 connected to it rotate. The adjusting collar 20 connected to the adjusting gear 19 will drive the combined support column 4 sleeved with it to move horizontally, thereby changing the relative distance between the two combined support columns 4.

[0031] The combined bracket includes a combined support column 4 disposed between two main end seats 1. The combined support column 4 is configured with multiple combined areas according to the number of module Bluetooth speakers. Different combined areas can rotate independently of each other, that is, the rotation of the combined areas of the combined support column 4 does not affect each other. This is used to realize the signal transmission and charging of each individual module Bluetooth speaker. The touch-connection module is disposed in each combined area of ​​the combined support column 4. The advantages of adopting the above are: dividing the combined support column 4 into multiple independently rotatable combined areas, the advantage is that each module Bluetooth speaker can independently adjust its orientation angle relative to the speaker body according to the user's needs, thereby precisely controlling the directivity of each channel during multi-channel stereo playback. This design allows users to fine-tune the sound field according to the actual listening position, greatly improving the freedom of surround stereo construction and the ability to optimize the listening experience.

[0032] Furthermore, the touch-sensitive communication module includes a signal contact groove on the outer wall of the combined support column 4, and a signal contact strip in contact with the signal contact groove on the inner wall of the connecting combination port 9. When the connecting seat 8 is combined and connected with the combined support column 4, the signal contact strip 11 contacts the signal contact groove. The touch-sensitive communication structure adopts an exposed signal contact strip 11 and a concealed signal contact groove. Its advantage is that when the module Bluetooth speaker card is connected to the combined support column 4, the two can automatically align and establish a reliable electrical connection without the need for additional cable plugging and unplugging.

[0033] The modular Bluetooth speaker includes an adjustable storage base 5, which is snapped into a combination support column 4. One side of the adjustable storage base 5 is connected to a connecting seat 8 via a damping pivot 7. The connecting seat 8 has a connecting combination port 9, which is compatible with the combination support column 4 and can be assembled and disassembled. A locking port 10 is provided on the side wall of the adjustable storage base 5 away from the connecting combination port 9.

[0034] The adjustable storage base 5 has a built-in Bluetooth player 6 connected via a torsion connector. The torsion connector includes an outer frame 12 connected to the Bluetooth player 6. The adjustable storage base 5 has a torsion storage opening 13. The outer wall of the outer frame 12 has a torsion groove 14. The inner wall of the torsion storage opening 13 is provided with a torsion guide post 15 that works in conjunction with the torsion groove 14. The bottom of the outer frame 12 is connected to the inner wall of the torsion storage opening 13 via a contact spring.

[0035] By setting a spring, when the module Bluetooth speaker is removed, it can be rotated to automatically pop out the outer frame 12 and the Bluetooth player 6 inside.

[0036] The advantage of using the aforementioned torsion connector is that when it is necessary to remove the Bluetooth player 6, it can be moved out naturally by rotating the outer frame 12.

[0037] Furthermore, the speaker end cover 2 is equipped with a main energy storage unit, the connector 8 is equipped with a module energy storage unit, and the speaker body is equipped with an external power supply cable to supply power to the main energy storage unit and the module energy storage unit. When the module Bluetooth speakers are combined on the speaker body, the system can automatically charge each module energy storage unit in a centralized manner by touching the connection module, without having to connect a separate charging cable for each sub-speaker.

[0038] This integrated power management solution greatly simplifies the user's charging process and ensures that all audio units are fully charged every time the user goes out.

[0039] It should be noted that the multi-channel Bluetooth speaker in this solution has three playback modes: standalone playback mode, integrated playback mode, and separate playback mode. In standalone playback mode, rotate the module Bluetooth speaker between the two main terminals 1. When the two combined support pillars 4 approach each other, the module Bluetooth speaker that is connected between the two combined support pillars 4 will be clamped and limited, so that the module Bluetooth speaker is in a stored state, which meets the requirements of the main player 3 on the speaker body to work alone. The advantage of the standalone playback mode is that when users only need basic audio playback, all the modular Bluetooth speakers can be stored and clipped between the main body structure. In this case, the product presents a compact, integrated form, making it convenient for desktop placement or portability. At the same time, the stored modular speakers are in a charging and protection state, which not only prevents the speaker units from accumulating dust and being damaged due to exposure, but also ensures that the modular speakers are fully charged and ready to use when extended use is needed.

[0040] In the integrated playback mode, the two combined pillars 4 are moved away from each other by the combined adjustment component, so that the original locking port 10 is disengaged from the locking of one side of the combined pillar 4. At this time, the module Bluetooth speaker is rotated to rotate through the connecting combination port 9, so that it is arranged on both sides of the main end seat 1. At this time, the angle of the Bluetooth player 6 located on it is changed by rotating the adjustable storage base 5, so as to satisfy the common stereo playback of multiple module Bluetooth speakers with different playback angles and the main player 3. The core advantage of the integrated playback mode is that all speaker units remain physically a single unit, but the directional angle of each module can be adjusted independently. This solves the problem of traditional integrated speakers having a fixed sound field and being unable to adapt to different listening positions. Users can finely adjust the deflection angle of each Bluetooth speaker module to create a multi-channel array with clear directionality, thereby significantly expanding the width and depth of the sound field without increasing the floor space, and obtaining a more immersive stereo experience.

[0041] In the split playback mode, after rotating the module Bluetooth speaker, the connection between the connector 9 and the support column 4 can be directly disconnected, allowing multiple module Bluetooth speakers to be removed and placed around the perimeter for multi-position playback. They can then be connected to the main player 3 via Bluetooth signal to achieve synchronous multi-point playback.

[0042] The split playback mode design enables this audio system to achieve a true physical surround sound layout. Users can flexibly place the detached Bluetooth module speakers in different corners of the room, and build a distributed audio network with the main player 3 to produce sound from multiple points simultaneously. This mode is especially suitable for scenarios such as home theaters, parties, or large conference rooms, and can effectively eliminate listening dead zones, allowing every listener in the space to experience a balanced, full, and immersive sound effect.

[0043] In summary, this solution provides a modular stereo multi-channel Bluetooth speaker that, through an innovative detachable modular stand, intelligent touch-sensitive connection module, and automatic signal switching logic, achieves free transformation from compact storage and an integrated multi-channel array to a distributed wireless surround system. This design significantly improves the spatial adaptability and sound field plasticity of Bluetooth speaker products, while maintaining high integration and portability, giving users unprecedented personalized sound field customization capabilities, and possesses strong market promotion value and industrial application prospects.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
