[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0042] Please refer to Figures 1-8 This utility model proposes a connection structure between a speaker and an effects unit, including a speaker 1 and an effects unit 2; the speaker 1 is provided with a first contact surface 11, and the effects unit 2 is provided with a second contact surface 21, and the first contact surface 11 and the second contact surface 21 are correspondingly arranged; a connection structure 3 and at least two sets of magnetic attraction structures 4 are provided between the speaker 1 and the effects unit 2; the connection structure 3 is located between the two sets of magnetic attraction structures 4; the connection component is used to establish an electrical connection, and the magnetic attraction structure 4 is used to provide magnetism and connect the speaker 1 and the effects unit 2; a control module 5 is provided inside the speaker 1 and the effects unit 2 respectively, and a plug interface 6 is provided on one side of the speaker 1 and the effects unit 2 respectively, and the plug interface 6 is electrically connected to the control module 5.

[0043] In this embodiment, the speaker 1 has a first contact surface 11, and the effects unit 2 has a second contact surface 21. A connecting structure 3 and at least two sets of magnetic attraction structures 4 are provided between the speaker 1 and the effects unit 2. The connecting structure 3 is respectively located on the first contact surface 11 and the second contact surface 21, and the magnetic attraction structures 4 are respectively located on the first contact surface 11 and the second contact surface 21. The magnetic attraction structures 4 are used to provide magnetism. Through the magnetic attraction of the magnetic component 43, the effects unit 2 can be easily attracted to the speaker 1, eliminating complicated installation steps. In addition, the magnetic attraction structures 4 can also easily remove the effects unit 2 when needed, making it more convenient for later maintenance or replacement. The connecting structure 3 is mainly used to establish an electrical connection. When the effects unit 2 and the speaker 1 are electrically connected through the connecting structure 3, the connecting boss 31 of the connecting structure 3 is inserted into the insertion slot 32, and the telescopic pin 331 abuts against the fixed contact 332. The elastic design of the telescopic pin 331 ensures good contact between the telescopic pin 331 and the fixed contact 332. The first contact surface 11 and the second contact surface 21 are correspondingly arranged to ensure the accuracy of the connection and electrical connection between the speaker 1 and the effects unit 2, avoiding connection instability or signal loss due to misalignment. After the effects unit 2 and the speaker 1 are electrically connected, the fixed contact 332 is electrically connected to the telescopic pin 331. The signal transmission path is that the audio signal is input from the audio interface 62 and sent to the control module 5 of the effects unit 2. The control module 5 of the effects unit 2 processes the audio signal, such as adding echo, delay, distortion, reverb, etc. After processing, the signal is transmitted to the fixed contact 332, which transmits the signal to the telescopic pin 331 and then to the amplifier of the control module 5 of the speaker 1. The amplifier amplifies the signal and drives the speaker to play it. The design of the magnetic structure 4 and the connection structure 3 makes the connection and disassembly of the speaker 1 and the effects unit 2 more convenient and easier to carry, meeting the needs of different scenarios.

[0044] Please refer to Figures 4-6 The magnetic structure 4 includes a magnetic boss 41, a magnetic groove 42, and a magnetic element 43. The magnetic boss 41 and the magnetic groove 42 are correspondingly arranged. The magnetic boss 41 is provided with a first groove 411, the magnetic groove is provided with a magnetic hole 421, and the first groove 411 and the magnetic hole 421 are respectively provided with magnetic elements 43.

[0045] In specific implementation: Magnetic components 43 are respectively disposed in the first groove 411 and the magnetic suction hole 421, specifically, the magnetic components 43 are fixedly connected to the bottom surface of the first groove 411; the magnetic groove has a magnetic suction hole, the magnetic components 43 are disposed in the effect unit, and the position corresponds to the magnetic suction hole 421, and the area of ​​the magnetic components 43 is larger than the area of ​​the magnetic suction hole 421 (that is, the magnetic components 43 can completely cover the edge of the magnetic suction hole 421). The effect unit 2 is connected to the speaker 1 through the magnetic components 43. The use of strong magnetic components 43 allows the effect unit 2 and the speaker 1 to be connected by simply bringing them close together, and provides a stable fixing force to ensure that the effect unit 2 and the speaker 1 are not easily detached during use; at the same time, it avoids the cumbersome operation of traditional screw fixing or clip connection, improving the user experience. Among them, the magnetic components 43 include, but are not limited to, neodymium iron boron (NdFeB) magnets, samarium cobalt (SmCo) magnets, and alnico magnets. Traditional screw or fastener connections leave noticeable marks on the surface of the equipment, affecting its overall design. In contrast, the magnetic structure 4 is embedded in the first groove 411 and the magnetic slot 42, respectively, making the magnetic component 43 invisible from the outside. This results in a cleaner, more sophisticated look for the equipment, enhancing its market competitiveness.

[0046] Please refer to the attached document. Figures 4-7 The magnetic element 43 includes a first magnetic element 431 and a second magnetic element 432; the polarity of the first magnetic element 431 is opposite to that of the second magnetic element 432, in order to provide the maximum adsorption force.

[0047] In practical implementation: the magnetic component 43 includes a first magnetic component 431 and a second magnetic component 432, with the polarity of the first magnetic component 431 being opposite to that of the second magnetic component 432. When the speaker 1 and the effects unit 2 are close together, the first magnetic component 431 and the second magnetic component 432 attract each other, thus achieving quick fixation. This design not only facilitates user operation but also provides additional fixing force, ensuring the stability of the connection. The position, shape, and number of magnetic components 43 can be adjusted according to actual needs. The combined use of the connection structure 3 and the magnetic attraction structure 4 ensures the stability of the physical connection between the speaker 1 and the effects unit 2, avoiding signal loss or equipment damage due to loosening. The magnetic connection between the effects unit 2 and the speaker 1 makes the device more portable, allowing users to easily carry and move it.

[0048] Please refer to the attached document. Figures 4-5 The connecting structure 3 includes a connecting boss 31, a plug groove 32, and a telescopic component 33. The connecting boss 31 and the plug groove 32 are correspondingly arranged. The telescopic component 33 includes a telescopic pin 331 and a fixed contact 332. The connecting boss 31 is provided with a second groove 311, the telescopic pin 331 is located in the second groove 311, and the fixed contact 332 is located in the plug groove 32.

[0049] In practical implementation: The telescopic pin 331 and fixed contact 332 of the telescopic assembly 33 are mainly used for signal transmission, ensuring high-quality sound signal transmission between the speaker 1 and the effects unit 2. The connecting boss 31 of the telescopic pin 331 is inserted into the insertion slot 32 until the telescopic pin 331 abuts against the fixed contact 332. At this time, the telescopic pin 331 shortens under the pressure of the fixed contact 332. The telescopic characteristic of the telescopic pin 331 generates a certain pressure between the telescopic pin 331 and the contact, which can maintain good electrical contact. In addition, the radius of the fixed contact 332 is larger than the radius of the telescopic pin 331, ensuring that the telescopic pin 331 can be accurately inserted into the insertion slot 32 and maintain stable contact with the fixed contact 332.

[0050] Please refer to the attached document. Figures 4-5 When the connecting boss 31 is located on the first contact surface 11, the insertion groove 32 is located on the second contact surface 21; when the connecting boss 31 is located on the second contact surface 21, the insertion groove 32 is located on the first contact surface 11.

[0051] In practical implementation: the connecting boss 31 is embedded in the plug slot 32, making the connection structure 3 more concealed and leaving no obvious connection marks on the surface. It also provides dustproof and waterproof functions to protect the internal circuitry from external environmental influences. The embedding of the connecting boss 31 into the plug slot 32 ensures a tighter fit between the first contact surface 11 and the second contact surface 21, avoiding excessive space occupation and ensuring a stable connection. The connecting boss 31 can be located on either the first contact surface 11 or the second contact surface 21, and the plug slot 32 can be located on either the second contact surface 21 or the first contact surface 11. The position, shape, and number of the connecting boss 31 and the plug slot 32 can be adjusted according to actual conditions.

[0052] Please refer to the attached document. Figure 1 and Figure 2 The interface 6 includes a power interface 61 and an audio interface 62; the speaker 1 and the effects unit 2 are respectively provided with a power interface 61 on one side for power supply; the effects unit 2 is also provided with an audio interface 62 on one side for inputting audio signals.

[0053] In practical implementation: A power interface 61 is provided on one side of both the speaker 1 and the effects unit 2. The power interface 61 of the speaker 1 can be located on the same side as the power interface 61 of the effects unit 2, or they can be located on different sides. The positions of the power interfaces 61 of the speaker 1 and the effects unit 2 can be adjusted according to the actual situation. An audio interface 62 is also provided on one side of the effects unit 2. Audio is input to the control module 5 of the effects unit 2 through the audio interface 62. The control module 5 of the effects unit 2 performs effects processing on the audio signal (such as reverb, delay, distortion, etc.). The speaker 1 and the effects unit 2 each have independent control modules 5 and interfaces 6, facilitating individual or combined use.

[0054] In another embodiment, the speaker 1 and the effects unit 2 are separated and used as two independent units. Power interfaces 61 are provided on one side of both the speaker 1 and the effects unit 2 to supply power to these two independent units. The speaker 1 also contains a Bluetooth device, which is electrically connected to the control module 5 of the speaker 1. A Bluetooth switch button is located on one side of the speaker 1; pressing the switch button turns the Bluetooth device on or off. Pressing the switch button turns on the Bluetooth device and enters pairing mode. External devices (such as mobile phones, tablets, etc.) search for the Bluetooth signal of the speaker 1 via Bluetooth. The user selects the speaker 1 on the external device and pairs it, thus completing the wireless connection between the external device and the speaker 1. The external device can transmit audio signals to the speaker 1 via Bluetooth. The control module 5 of the speaker 1 receives and processes the audio signals and then outputs sound by driving the speaker.

[0055] Please refer to the attached document. Figure 4 and Figure 5 The magnetic attraction structure 4 is symmetrically arranged on both sides of the connecting structure 3.

[0056] In practical implementation: The magnetic suction structure 4 is located between the speaker 1 and the effects unit 2, specifically on the first contact surface 11 of the speaker 1 and the second contact surface 21 of the effects unit 2, and is situated on both sides of the connecting structure 3, forming a symmetrical layout. This symmetrical layout of the magnetic suction structure 4 effectively balances the force distribution of the connection, preventing instability caused by force concentration. The symmetrical design ensures a stable connection between the speaker 1 and the effects unit 2 during use, reducing the risk of loosening due to vibration or accidental contact, thereby improving the balance and stability of the connection between the effects unit 2 and the speaker 1. The magnetic suction structure 4 also provides a certain degree of buffering, reducing the impact of vibration on connection stability, thus improving the reliability of the equipment in complex environments.

[0057] Please refer to the attached document. Figure 4 and Figure 5 The telescopic pin 331 protrudes from the first contact surface 11 or the second contact surface 21, and the fixed contact 332 protrudes from the bottom surface of the insertion slot 32.

[0058] In practical implementation: When the connecting boss 31 is located on the first contact surface 11, the insertion groove 32 is located on the second contact surface 21. The connecting boss 31 has a second groove 311, and the telescopic pin 331 is located within the second groove 311, protruding relative to the first contact surface 11; the fixed contact 332 is located within the insertion groove 32, protruding relative to the bottom surface of the insertion groove 32. When the connecting boss 31 is located on the second contact surface 21, the insertion groove 32 is located on the first contact surface 11; the telescopic pin 331 protrudes relative to the second contact surface 21. The protruding arrangement of the telescopic pin 331 and the fixed contact 332 makes it easier for the pin and contact to make contact, thereby improving the reliability and stability of the connection. The design of the telescopic pin 331 can adapt to different insertion forces, preventing poor contact due to over-insertion or uneven force.

[0059] Please refer to the attached document. Figure 4 , Figure 5 The height of the magnetic boss 41 is equal to the depth of the magnetic groove 42, and the height of the connecting boss 31 is equal to the depth of the insertion groove 32; the height of the magnetic boss 41 is equal to the height of the connecting boss 31.

[0060] In practical implementation: the height of the magnetic boss 41 is equal to the depth of the magnetic groove 42, the height of the connecting boss 31 is equal to the depth of the insertion groove 32, and the shape of the connecting boss 31 matches the shape of the insertion groove 32, ensuring smooth and precise fitting. Simultaneously, the magnetic boss 41 and magnetic groove 42, as well as the connecting boss 31 and insertion groove 32, also serve as limiters, preventing over-fitting of the effects unit 2 to the speaker 1. During the connection process between the effects unit 2 and the speaker 1, the connecting boss 31 is inserted into the insertion groove 32 until the bottom surface of the connecting boss 31 abuts against the bottom surface of the insertion groove 32; simultaneously, the magnetic boss 41 is inserted into the magnetic groove 42, and the bottom surface of the magnetic boss 41 abuts against the bottom surface of the magnetic groove 42, thus ensuring a tight fit between the first contact surface 11 and the second contact surface 21. This not only makes the connection between the effects unit 2 and the speaker 1 more compact but also makes the overall appearance of the speaker 1 and the effects unit 2 more harmonious, avoiding any abrupt or unsightly situations.

[0061] The height of the magnetic boss 41 is equal to the height of the connecting boss 31, that is, the height of the bosses on the first contact surface 11 or the second contact surface 21 is equal, which avoids the visual segmentation caused by the bosses being too high when connecting, thereby improving the overall aesthetics of the digital effects unit 2 and the speaker 1; in addition, the first contact surface 11 and the second contact surface 21 fit tightly together, which can effectively isolate external dust and moisture, and improve the protective performance of the equipment.

[0062] Please refer to the attached document. Figures 4-6 When the speaker 1 and the effects unit 2 are connected, there is a gap between the first magnetic component 431 and the second magnetic component 432. The gap is located between the magnetic boss 41 and the magnetic groove 42.

[0063] In specific implementation: the magnetic component 43 includes a first magnetic component 431 and a second magnetic component 432; wherein, a gap is provided between the first magnetic component 431 and the second magnetic component 432, the gap being located between the magnetic boss 41 and the magnetic groove 42, specifically between the first groove 411 on the magnetic boss 41 and the magnetic hole 421 in the magnetic groove 42; a part of the magnetic component 43 is fixedly disposed at the bottom of the first groove 411 on the magnetic boss 41, and the thickness of the magnetic component 43 is less than the depth of the first groove 411, and the other part of the magnetic component 43 is fixedly disposed inside the effect unit 2 and fits against the magnetic hole 421; when the speaker 1 is connected to the effect unit 2, the magnetic boss 41 abuts against the bottom of the magnetic groove 42, thereby forming a gap between the first groove 411 and the magnetic hole 421. When the magnetic component 43 is fully fitted, it increases vibration transmission between the speaker 1 and the effects unit 2, affecting sound quality or equipment stability. The gap acts as a buffer, reducing the transmission of vibration from the speaker 1 to the effects unit and maintaining stable sound quality. Furthermore, with frequent disassembly and assembly, a fully fitted magnetic component 43 can cause wear on its surface. The gap reduces direct contact with the magnetic component 43, preventing wear or damage and extending the equipment's lifespan.

[0064] In another embodiment, the first magnetic element 431 and the second magnetic element 432 are completely bonded together. The magnetic attraction increases as the distance between the magnetic elements 43 decreases, reaching its maximum value when the magnetic elements 43 are completely bonded, providing a more secure connection and reducing the possibility of the device coming loose. The completely bonded connection of the first magnetic element 431 and the second magnetic element 432 also effectively prevents dust, moisture, or other external foreign objects from entering the device, providing better protection and a cleaner appearance with smaller gaps between devices, resulting in a more integrated look. Furthermore, the thickness, size, shape, number, and position of the magnetic elements 43 can be adjusted according to actual needs.
