Description

Technical Field

[0001] This utility model relates to the field of audio equipment technology, and in particular to a dual-channel detachable Bluetooth power amplifier speaker. Background Technology

[0002] As devices for amplifying and reproducing audio signals, audio equipment has undergone numerous technological innovations since the 20th century, evolving from mono to stereo and from wired to wireless transmission, thanks to the development of electronic technology. Two-channel stereo technology, by creating a sense of space and direction through the signal differences between the left and right channels, has become one of the core functions of modern audio equipment. It is widely used in home theaters, multimedia entertainment, and portable audio devices, significantly enhancing the user's auditory experience.

[0003] In the current market, long, rectangular, dual-channel Bluetooth speakers designed for desktop use dominate the market. These products typically employ an integrated, compact structure, integrating the left and right channel units within a rectangular cavity, achieving spatial separation of the channels through physical layout. Their advantage lies in the clear sound field positioning created by the left and right channels when the user is within close proximity in a fixed environment such as a desktop. Combined with Bluetooth wireless connectivity, they balance ease of use with sound quality, making them a common audio accessory for computers, televisions, and other devices.

[0004] However, because the speaker units are fixed in a single cavity, their sound field positioning effect is highly dependent on the relative position of the user and the device. When the user moves to a location far from the desktop, the ratio of the distance between the left and right channels relative to the user's listening position decreases sharply, resulting in blurred sound image positioning and reduced stereo effect, thus failing to effectively leverage the core advantages of dual-channel technology. Furthermore, the fixed design is difficult to adapt to various usage scenarios. For example, if a user wants to place the speakers on either side of a room for a better sound field, existing products cannot achieve channel separation due to structural limitations, restricting their application flexibility. Utility Model Content

[0005] To overcome the disadvantages of location dependence, this invention provides a dual-channel detachable Bluetooth amplifier speaker, aiming to solve the above-mentioned shortcomings.

[0006] A dual-channel detachable Bluetooth amplifier speaker includes a main unit chassis, an amplifier board mounted in the middle of the main unit chassis, mounting frames connected to both ends of the main unit chassis, and channel speakers slidably connected within the mounting frames. The channel speakers are fixedly mounted on both sides of the main unit chassis. Each mounting frame has a built-in data interface. A Bluetooth module is integrated at the rear end of each channel speaker, and the Bluetooth module is wirelessly connected to the amplifier board. A battery is installed inside each channel speaker, and a charging module is integrated at the rear end of each channel speaker. The charging module interfaces with the data interface and is wiredly connected to the battery. A support component is provided at the bottom of the rear end of each channel speaker.

[0007] To further explain, the support assembly includes a guide rod, which is slidably connected to the bottom of the speaker channel. The guide rod cannot be detached from the speaker channel. A triangular block is connected to the bottom of the guide rod, and the triangular block is slidably connected inside the speaker channel. A return spring is sleeved on the guide rod, with its upper end connected to the speaker channel and its lower end connected to the triangular block.

[0008] To further explain, a first magnet is connected to the rear of the speaker channel, and a second magnet is slidably connected inside the mounting frame. A cover plate is connected to the middle of the second magnet, and the cover plate has a through hole that mates with the data interface. The first magnet and the second magnet are magnetically attracted to each other.

[0009] To further explain, a guide block is provided at the bottom front end of the mounting frame.

[0010] To further explain, an auxiliary block is connected to the top of the front end of the speaker channel.

[0011] To further explain, the bottom of the main unit chassis is connected to several stabilizing feet.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. Through the linkage design of detachable channel speakers and Bluetooth module, long-distance synchronous transmission of audio signals is realized. The battery automatically switches to power supply mode, so that the dual-channel function can remain effective in any placement scenario, extending the usage distance of dual channels.

[0014] 2. Through the automatic adjustment function of the support components, when the channel speaker is removed from the mounting frame, the rear end of the channel speaker is slightly suspended in the air, avoiding direct pressure on the internal components and ensuring the stability and safety of the internal components when placed at a distance.

Detailed Implementation

[0020] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0021] Example: A dual-channel detachable Bluetooth amplifier speaker, such as Figures 1-4 As shown, the system includes a main unit chassis 1, an amplifier board 2, a mounting frame 3, a data interface 4, channel speakers 5, a Bluetooth module 6, a charging module 7, a battery 8, and a support assembly. The amplifier board 2 is installed in the middle of the main unit chassis 1. Mounting frames 3 are connected to both ends of the main unit chassis 1. Channel speakers 5 are slidably connected within the mounting frames 3. Channel speakers 5 are fixedly installed on both sides of the main unit chassis 1. The mounting frame 3 has a built-in data interface 4, which serves as a channel for signal and power transmission. The rear of the channel speakers 5 integrates a Bluetooth module 6, which is wirelessly connected to the amplifier board 2. The Bluetooth module 6 is set to an automatic switch and is triggered by the connection / disconnection between the data interface 4 and the charging module 7. When the channel speakers 5 are removed from the mounting frame 3, they automatically turn on and connect to the amplifier board 2 via Bluetooth. When they are integrated, they automatically turn off, achieving seamless switching for long-distance audio transmission. The battery 8 is installed inside the channel speakers 5. The rear of the channel speakers 5 integrates a charging module 7, which is connected to the data interface 4 and wired to the battery 8. A support assembly is located at the bottom of the rear of the channel speakers 5.

[0022] like Figure 3 As shown, the support assembly includes a guide rod 9, a triangular block 10, and a return spring 11. The guide rod 9 is slidably connected to the bottom of the channel speaker 5, and the guide rod 9 cannot be detached from the channel speaker 5. The triangular block 10 is connected to the bottom of the guide rod 9 and is slidably connected inside the channel speaker 5. The return spring 11 is sleeved on the guide rod 9. The upper end of the return spring 11 is connected to the channel speaker 5, and the lower end is connected to the triangular block 10. The front and rear sides of the triangular block 10 are designed with bevels. When the channel speaker 5 is detached from the mounting frame 3, the triangular block 10 is pushed out by the return spring 11 to form a stable support point.

[0023] like Figure 2 and Figure 4 As shown, it also includes a first magnet 12, a cover plate 13, and a second magnet 14. The first magnet 12 is connected to the rear side of the channel speaker 5, and the second magnet 14 is slidably connected inside the mounting frame 3. The cover plate 13 is connected to the middle of the second magnet 14. When the channel speaker 5 is detached, the cover plate 13 closes the front opening of the mounting frame 3 to prevent dust or foreign objects from entering and to protect the data interface 4 and the internal track. The cover plate 13 has a through hole that mates with the data interface 4. The first magnet 12 and the second magnet 14 are magnetically attracted to each other.

[0024] like Figure 4 As shown, it also includes a guide block 15. The bottom front end of the mounting frame 3 is provided with a guide block 15. The guide block 15 is designed with a slope. When the channel speaker 5 is retracted, it squeezes the triangular block 10, guides it to slide into the channel speaker 5 and compresses the reset spring 11, and assists in the retraction of the support component.

[0025] like Figure 2 As shown, it also includes an auxiliary block 16. The front top of the channel speaker 5 is connected to the auxiliary block 16. The auxiliary block 16 provides a force point for the user through its protruding design, making it easier to remove and put in the channel speaker 5.

[0026] like Figure 1 As shown, it also includes stabilizing feet 17. Several stabilizing feet 17 are connected to the bottom of the host case 1. The stabilizing feet 17 improve the stability of the host case 1 in desktop and other scenarios, and prevent it from sliding or tilting.

[0027] When the user is close to the main unit 1, the data interface 4 is fully connected to the charging module 7 at the rear of the channel speakers 5. The power amplifier board 2 in the middle of the main unit 1 transmits audio signals to the channel speakers 5 through the data interface 4. The channel speakers 5 fixed at both ends of the main unit 1 and the channel speakers 5 sliding in on both sides work together, and the four channel speakers 5 output in coordination, so that the user can clearly perceive the separation of the two channels when using it at close range, creating a three-dimensional and layered sound field effect.

[0028] When the user needs to use the speaker from a distance, they can pull the auxiliary block 16 outwards to remove the speaker 5 from the mounting frame 3. The charging module 7 will then disconnect from the data interface 4, and the battery 8 will automatically switch to power supply mode, continuously providing power to the speaker 5. At the same time, the Bluetooth module 6 integrated at the rear of the speaker 5 will activate and establish a wireless Bluetooth connection with the amplifier board 2 inside the main unit 1, enabling long-distance synchronous transmission of audio signals. During the removal process, the guide rod 9 at the bottom of the rear of the speaker 5 will move downwards, stretching the return spring 11 and pushing the triangular block 10 downwards out of the bottom of the speaker 5 to form a support point. When placing the speaker 5, the triangular block 10 will contact the contact surface, making the rear of the speaker 5 slightly suspended, preventing direct pressure on components such as the rear charging module 7 and Bluetooth module 6. Furthermore, regardless of the placement position, the Bluetooth module 6 can maintain synchronous output of both channels, effectively extending the effective usage distance of the two channels.

[0029] During the removal of the channel speaker 5, the user gently pushes the auxiliary block 16 at the top front with their finger. The protruding design of the auxiliary block 16 makes applying force easier. The first magnet 12 surrounding the rear of the channel speaker 5 moves outward, pulling the second magnet 14, which is slidably connected inside the mounting frame 3, to move synchronously. The second magnet 14 drives the cover plate 13 connected in the middle to slide towards the front port of the mounting frame 3. When the channel speaker 5 is completely detached from the mounting frame 3, the cover plate 13 reaches the front opening of the mounting frame 3, sealing the opening and preventing dust or foreign objects from entering the mounting frame 3, thus avoiding interference with the subsequent insertion of the channel speaker 5 and the docking of the data interface 4.

[0030] When the battery 8 is low on power, the user can plug the external power cord into the charging module 7 at the rear of the speaker 5 to charge the battery 8 via a wired connection. After use, the speaker 5 should be retracted into the mounting frame 3, with the rear end of the speaker 5 aligned with the front opening of the mounting frame 3 and pushed in. At this time, the triangular block 10 at the bottom of the speaker 5 contacts the guide block 15 at the bottom front of the mounting frame 3. The inclined surface of the guide block 15 and the inclined surface of the triangular block 10 press against each other, guiding the triangular block 10 to slide into the speaker 5. The return spring 11 is compressed, causing the guide rod 9 to move upward, completing the retraction of the triangular block 10 and the guide rod 9. Simultaneously, the first magnet 12 on the rear side of the speaker 5 approaches the second magnet 14 inside the mounting frame 3, and the two are magnetically attracted and fixed. The cover plate 13 slides into the mounting frame 3 along with the speaker 5. The charging module 7 reconnects with the data interface 4, the Bluetooth module 6 automatically shuts down, and the speaker 5 returns to its fixed state inside the mounting frame 3, completing the retraction.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
