Description

Technical Field

[0001] The utility model belongs to the technical field of educational auxiliary equipment, and specifically relates to a one-transmit-multiple-receive type battery wireless classroom loudspeaker. Background Art

[0002] With the advancement of education modernization, wireless loudspeakers are increasingly used in teaching. Especially in modern teaching environments, the number of students is increasing year by year, and the size of classrooms is expanding, which poses severe challenges to teachers' teaching methods and sound propagation effects. In order to ensure that students in the back row can hear the teacher's explanation clearly, teachers often need to increase the volume, which not only increases their workload, but long-term loud lectures may also cause vocal cord fatigue and even cause related health problems. Therefore, when teachers are teaching, in order to ensure that the sound can be more effectively transmitted to the ears of every student, they usually use bees to diffuse the sound. This practice helps to improve the quality of teaching and ensure that every student can hear the teacher's explanation clearly.

[0003] Although traditional wired bee receivers have solved the problem of sound propagation to a certain extent, there are still many limitations in practical applications. Existing wireless amplifiers usually adopt a one-to-one transmission mode, that is, one transmitter corresponds to one receiver, which limits their scope of use and flexibility. For example, when a teacher moves on the podium, students in the front row may feel that the sound is too harsh, while students in the back row may not feel that the sound increase is obvious. In addition, even if you try to use wireless bees to place the speakers in the back row, the sound quality will be greatly reduced due to signal attenuation and loss during wireless transmission, and it cannot meet the needs of high-quality audio transmission.

[0032] Please see attached Figure 1 - Figure 7 As shown, the utility model provides a one-transmit-multiple-receive type battery wireless classroom loudspeaker, comprising:

[0033] A transmitting end 1 and a receiving end 2, wherein a mounting assembly 3 is provided on the receiving end 2, and a connecting ear 4 is fixedly connected to the receiving end 2:

[0034] The transmitting end 1 comprises a microphone 11, on which a first storage battery 12, a wireless transmitting module 13 and a first control module 14 are installed;

[0035] The receiving end 2 comprises a housing 21 on which a wireless receiving module 22, a second control module 23, a second storage battery 24 and a speaker 25 are mounted;

[0036] Among them, the installation component 3 includes a shell 31, which is fixedly connected to the outer shell 21. One side of the shell 31 is provided with adsorption parts 32 distributed in an array, and the side of the outer shell 21 is provided with four limiting parts 33, and the limiting parts 33 are provided with quick-release parts 34.

[0037] In this embodiment, the microphone 11 is used to collect the teacher's voice signal; the wireless transmission module 13 converts the collected voice signal into a wireless signal and transmits it; the first storage battery 12 is used for power supply; the first control module 14 is used to control the switch, volume adjustment and other functions of the transmitting end 1;

[0038] The wireless receiving module 22 is used to receive the wireless signal sent by the transmitting terminal 1; the speaker 25 converts the received wireless signal into a sound signal for playback; the second storage battery 24 is used for power supply; the second control module 23 is used to control the switch, volume adjustment and other functions of the receiving terminal 2;

[0039] The design of the mounting assembly 3 enables the receiving terminal 2 to be quickly disassembled and installed. The array distribution of the adsorption portion 32 allows the receiving terminal 2 to be easily adsorbed on a plane such as a blackboard, a whiteboard, or a tile, which not only saves space but also facilitates the operation of the teacher. The coordinated use of the limiting portion 33 and the quick-release portion 34 allows the mounting assembly 3 to be quickly disassembled when needed, making it convenient for the teacher to quickly install the receiving terminal 2 where it is needed. When the receiving terminal 2 needs to be fixed in a certain position for a long time, it can be fixed using the connecting ear 4.

[0040] In summary, the transmitting end 1 and the receiving end 2 of this implementation are reasonably designed and practical, can meet the needs of teachers in the classroom, and improve the teaching quality and efficiency;

[0041] It should be added that there are multiple receiving ends 2, and the one-transmit-multiple-receive technology is adopted to realize the audio signal transmission of one transmitting end 1 corresponding to multiple receiving ends 2, thereby improving the use range and flexibility of the loudspeaker; the wireless transmission technology is adopted to avoid the problem of messy and easily damaged cables of traditional loudspeakers, thereby improving the teaching quality.

[0042] In a preferred embodiment, please refer to Figure 3 - Figure 5 The adsorption portion 32 includes a hollow cylinder 321, which is fixedly connected to the shell 31, and a suction cup 322 is provided at the other end of the hollow cylinder 321. A round rod 323 is provided in the hollow cylinder 321, and the round rod 323 is slidably inserted in the shell 31, one end of the round rod 323 is fixedly connected to a piston plate 324, and the other end of the round rod 323 is fixedly connected to a movable plate 325, and a pressing rod 326 is fixedly connected to the movable plate 325, and the pressing rod 326 slides along the slide groove on the shell 31, wherein the limiting portion 33 includes a fixed block 331, which is fixedly connected to the shell 21, and a movable rod 332 is slidably inserted on the fixed block 331, and a compression spring 333 is sleeved on the outer wall of one end of the movable rod 332.

[0043] In this embodiment, when fixing the receiving end 2, firstly, several suction cups 322 are closely attached to a smooth wall surface, such as a surface of a material such as a blackboard, a whiteboard or a tile. Then, an appropriate force is applied to make the suction cup 322 fit closely to the wall surface, thereby exhausting the air inside it and completing the adsorption process. Thereafter, the pressing rod 326 is pulled to move it toward the receiving end 2. During this process, the displacement of the pressing rod 326 will drive the movable plate 325 and the round rod 323 fixed thereto to move synchronously. The movement of the round rod 323 then drives the piston plate 324 to slide along the inner wall of the hollow cylinder 321. The movement of the piston plate 324 will promote the flow of air inside the hollow cylinder 321, thereby enhancing the adsorption force at the suction cup 322, effectively improving the fixing effect, and preventing the receiving end 2 from loosening or falling off during use.

[0044] When the pressing rod 326 is pulled, when the pressing rod 326 moves to the movable rod 332, it pushes the movable rod 332 to move to both sides and stretches the compression spring 333. Once the pressing rod 326 passes through the two movable rods 332, the movable rods 332 lose their resistance, and the compression spring 333 generates a restoring force, which pushes the two movable rods 332 to move closer to each other, thereby limiting the pressing rod 326 and preventing it from restoring itself, so as to ensure that the suction cup 322 can maintain a continuous adsorption force.

[0045] Secondly, please also refer to Figure 4 and Figure 5 The quick-release part 34 includes a support frame 341, which is fixedly connected to one end of the movable rod 332. A rack 342 is fixedly connected to the support frame 341, and a guide block 343 is fixedly connected to the rack 342. A limit block 344 is fixedly connected to the housing 21, and the guide block 343 is slidably connected to the limit block 344. The limit block 344 is connected to a gear 345 by rotation through a support rod, wherein both ends of the compression spring 333 are fixedly connected to the fixed block 331 and the support frame 341.

[0046] In this embodiment, when disassembling, the U-shaped rod connected between the two support frames 341 is first pulled to cause it to move outward. In this process, the support frame 341 first moves outward with the outward movement of the U-shaped rod, thereby driving the movable rod 332 to move and stretching the compression spring 333. At the same time, the movement of the support frame 341 will also drive the rack 342 to move synchronously. During the movement, the rack 342 will be driven to rotate through the meshing action with the gear 345. The rotation of the gear 345 will further drive the rack 342 on the other side to move in the opposite direction, thereby realizing the mutual distance between the two movable rods 332. When this series of actions is completed, the pressing rod 326 will lose its original limiting function. Subsequently, the release of the pressing rod 326 will allow the movable plate 325, the round rod 323 and the piston plate 324 to return to the initial position, thereby reducing the suction force generated by the suction cup 322 and realizing the disassembly of the receiving end 2.

[0047] In a preferred embodiment, please refer to Figure 6 and Figure 7 The first battery 12 and the second battery 24 are both silicon-carbon negative electrode lithium batteries.

[0048] In this embodiment, both the transmitting end 1 and the receiving end 2 use a thin and high-energy silicon-carbon negative electrode lithium battery as a power source, which has the characteristics of long battery life and fast charging, and meets the needs of long-term use; this battery has the characteristics of light weight, large capacity, and long cycle life, which can ensure that the transmitting end can still maintain stable performance during long-term use, while meeting the needs of being thin and portable.

[0049] Next, please refer to Figure 6 and Figure 7 , the wireless transmitting module 13 and the wireless receiving module 22 both adopt the star flash communication module.

[0050] In this embodiment, the star flash communication module of the wireless transmitting module 13 and the wireless receiving module 22 is uniquely designed, and they use high-frequency signals to transmit and receive data in a wireless environment. This design not only ensures the efficiency and stability of data transmission, but also makes the entire system more flexible and convenient.

[0051] After receiving data from other devices or systems, the wireless transmitter module 13 will immediately convert the data into high-frequency signals and send them out through the wireless channel. Its built-in Star Flash communication protocol ensures the integrity and security of the data and effectively avoids the loss or tampering of data during transmission. At the same time, the wireless transmitter module 13 also has the function of intelligently adjusting the transmission power, which can automatically adjust according to the signal quality and transmission distance to achieve the best communication effect.

[0052] The wireless receiving module 22 is responsible for receiving high-frequency signals from the wireless transmitting module 13 or other wireless transmitting sources and converting them into raw data. During the receiving process, the wireless receiving module 22 will use the decoding function of the Star Flash communication module to verify and correct the data to ensure that the received data is accurate. In addition, the wireless receiving module 22 also has a strong anti-interference ability, can work stably in a complex electromagnetic environment, and ensure reliable data transmission.

[0053] Through the design of this Star Flash communication module, the wireless transmitting module 13 and the wireless receiving module 22 can achieve efficient, stable and secure wireless data transmission, providing strong support for teaching scenarios.

[0054] In addition, the SparkLink communication module supports one send and multiple receive. Specifically, SparkLink technology provides two wireless communication interfaces: SLE (SparkLink Low Energy): In appropriate scenarios, it can support one-to-many communication mode.

[0055] SLB (SparkLink Basic): SLB has the characteristics of high speed, high reliability, high synchronization accuracy, and support for multiple concurrency. This means that under high-speed and high-reliability transmission, SLB can support the function of sending multiple messages at once. In particular, it supports 80 user data concurrency within 1ms, which directly proves its ability to communicate with multiple users at the same time.

[0056] In summary, the Star Flash communication module, especially its SLB interface, has an efficient one-transmit-multiple-receive function. This function allows a single transmitter 1 to transmit signals to multiple receivers 2 in parallel, achieving wide propagation of sound sources at different locations, thus effectively overcoming the various limitations commonly found in traditional bee receivers in practical applications.

[0057] The working principle of this utility is:

[0058] The teacher only needs to wear the transmitter 1, turn on the switch and adjust the volume to transmit the voice signal to multiple receivers 2 in the classroom. After receiving the wireless signal, the receiver 2 plays the sound through the speaker 25 to achieve synchronous playback of the audio signal. The teacher can adjust the volume of the transmitter 1 as needed to meet the teaching needs in different scenarios;

[0059] The design of the mounting assembly 3 enables the receiving terminal 2 to be quickly disassembled and installed. The array distribution of the adsorption portion 32 allows the receiving terminal 2 to be easily adsorbed on a plane such as a blackboard, a whiteboard, or a tile, which not only saves space but also facilitates the operation of the teacher. The coordinated use of the limiting portion 33 and the quick-release portion 34 allows the mounting assembly 3 to be quickly disassembled when needed, making it convenient for the teacher to quickly install the receiving terminal 2 where it is needed. When the receiving terminal 2 needs to be fixed in a certain position for a long time, it can be fixed using the connecting ear 4.

[0060] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
