Description

Technical Field

[0001] This utility model relates to the field of modular speaker technology, specifically to a modular wireless speaker. Background Technology

[0002] Modular speakers enhance the sound experience through the collaboration of multiple components, but traditional products rely on mechanical connectors such as bolts for assembly. This method is prone to connection failure due to thread wear during long-term use, and the installation process requires special tools, which is cumbersome and time-consuming. It is also difficult to flexibly adjust the combination form according to the usage scenario, which is insufficient in terms of installation convenience and structural stability, and to a certain extent, it limits the spatial adaptability and user experience of the equipment.

[0003] Chinese Patent Publication No. CN215682551U discloses a freely combinable wireless speaker. In operation, the auxiliary speaker's locking block is aligned with the slot of the main speaker's connection mechanism. The auxiliary speaker is then pushed to engage the locking block in the slot. At this point, a limiting block engages with the auxiliary speaker's limiting hole. Rotating the auxiliary speaker allows the locking block to turn inside the circular protrusion until it is facing forward, completing the engagement. The same process is used to install another auxiliary speaker. To change the configuration, the auxiliary speaker and main speaker's connection ends are aligned and connected via a first magnet at one end of the auxiliary speaker. Then, a rubber leg at the bottom of the auxiliary speaker is inserted into a leg hole at the top of the main speaker. A second magnet at the bottom of the leg hole magnetically attracts an iron block inside a deep hole in the rubber leg, fixing the auxiliary speaker to the top of the main speaker. This process, through the engagement of the locking block and slot, the magnetic attraction between the magnet and the iron block, and the coordination of the limiting structure, allows for assembly without screws. Furthermore, the rubber pad and rubber legs reduce vibration interference and provide a damping effect, enabling flexible switching between various configurations. However, the device in this patent relies on magnetic force for positioning. The main drawback of magnetic force for positioning is that it is easily affected by external magnetic fields or metal objects, which can lead to positioning deviation or unstable connection. Long-term use or frequent disassembly and assembly may cause the magnet to demagnetize, and the attraction force will gradually weaken, affecting long-term reliability.

[0004] Therefore, the present invention aims to provide a modular wireless speaker to solve the above-mentioned problems. Utility Model Content

[0005] To address the aforementioned issues, a modular wireless speaker is provided. By installing connection sockets at both ends of the main speaker, a connection mechanism consisting of guide blocks, limit blocks, guide rods, and return springs within the sockets, in conjunction with the guide ramps on the connection blocks, enables rapid insertion and removal and automatic locking through the coordination of ramp guidance and spring reset. This solves the problems of existing modular wireless speakers where the magnetic-assisted positioning of the auxiliary and main speakers is susceptible to interference and has poor reliability over long-term use.

[0006] To address the problems of existing technologies, this utility model provides a modular wireless speaker, including a main speaker and two auxiliary speakers at both ends of the main speaker. A connecting mechanism for assembling and installing the auxiliary speakers is provided between the two ends of the main speaker and the auxiliary speakers. The connecting mechanism includes a connecting socket at one end of the main speaker, guide blocks at both ends of the top of the connecting socket, limit blocks slidably connected to the guide blocks, guide grooves adapted to guide rails on the limit blocks, a guide rod at the center of the top of the connecting socket, a guide slot adapted to the guide rod on the limit blocks, and a return spring sleeved on the guide rod. A connecting plug is provided at one end of the auxiliary speakers, a first guide slope on the outward side of the limit block, and a second guide slope adapted to the limit block on the outward side of the connecting plug. When the auxiliary speakers are installed on the main speaker, the first slope and the second slope abut against each other, the connecting plug is further inserted, the limit block is lifted up until the connecting plug is inserted into the connecting socket, and the limit block resets to limit the connecting plug.

[0007] Preferably, the main speaker has a connection socket and a connection plug at its two ends, respectively. The auxiliary speaker installed at one end of the connection socket is provided with a connection plug, and the auxiliary speaker installed at one end of the connection plug is provided with a connection socket.

[0008] Preferably, the limiting block is provided with an auxiliary gripper for the operator to hold.

[0009] Preferably, the main speaker has a guide rail on top and the auxiliary speaker has a groove at the bottom that matches the guide rail.

[0010] Preferably, the connecting plug of the auxiliary speaker can be inserted into the connecting socket on another auxiliary speaker, and the two auxiliary speakers are combined together on the guide rail by the cooperation of the connecting plug and the connecting socket.

[0011] Preferably, a fixing hole is provided in the groove between the side of the guide rail and the bottom of the auxiliary speaker box. When the two auxiliary speakers are combined together and the fixing hole in the groove of the auxiliary speaker box coincides with the fixing hole on the side of the guide rail, a fixing pin is inserted into the fixing hole.

[0012] Preferably, the fixing pin is magnetically attached to the fixing hole.

[0013] Preferably, one end of the fixing pin has a sliding groove for easy insertion and removal by the operator.

[0014] The advantages of this utility model compared to the prior art are:

[0015] 1. In this utility model, the inclined guide of the connecting mechanism and the spring reset are combined to replace the traditional magnetic positioning with mechanical locking, which avoids the positioning offset and unstable connection caused by interference from external magnetic fields or metal objects. Moreover, the magnet will not demagnetize or the adsorption force will not weaken due to long-term use or frequent disassembly and assembly, which significantly improves the reliability and long-term stability of the connection.

[0016] 2. In this utility model, the main speaker is provided with a connection socket and a connection plug at both ends, which can be precisely connected with the corresponding connection plugs and connection sockets on the auxiliary speakers at both ends, realizing a bidirectional combinable connection between the main speaker and the auxiliary speakers, enhancing the flexibility and adaptability of the speaker combination.

[0017] 3. The auxiliary gripper on the limiting block in this utility model provides a force application point for disassembly. Combined with the magnetic adsorption and tossing groove design of the fixing pin, the magnetic force guides the pin to be inserted quickly and accurately during installation. During disassembly, the tossing groove and auxiliary gripper facilitate the application of force. At the same time, the cooperation between the guide rail and the slide, and the fixing hole and the pin, forms a double mechanical limit in the horizontal and lateral directions, which improves the convenience of operation and further strengthens the stability of the overall connection structure.

[0026] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0027] Reference Figures 1-7 The following describes a modular wireless speaker: A main speaker 1 with two auxiliary speakers 2 at both ends. A connecting mechanism 3 for assembling the auxiliary speakers 2 is provided between the two ends of the main speaker 1 and the auxiliary speakers 2. The connecting mechanism 3 includes a connecting socket 4 at one end of the main speaker 1. Guide blocks 5 are provided at both ends of the top of the connecting socket 4. Limiting blocks 6 are slidably connected to the guide blocks 5. The limiting blocks 6 have guide grooves 7 adapted to guide rails. A guide rod 8 is provided at the center of the top of the connecting socket 4. The limiting blocks 6... The upper part has a guide slot 9 adapted to the guide rod 8. A return spring is sleeved on the guide rod 8. One end of the auxiliary speaker 2 is provided with a connecting plug 10. The limiting block 6 has a first guide slope on the outward side. The connecting plug 10 has a second guide slope adapted to the limiting block 6 on the outward side. When the auxiliary speaker 2 is installed on the main speaker 1, the first slope and the second slope abut against each other. The connecting plug 10 continues to be inserted, and the limiting block 6 is pushed up until the connecting plug 10 is inserted into the connecting socket 4. The limiting block 6 resets and limits the connecting plug 10.

[0028] In existing technologies, the auxiliary speaker 2 and the main speaker 1 are primarily positioned using magnetic assistance. The main drawback of magnetic-assisted positioning is its susceptibility to interference from external magnetic fields or metal objects, leading to positioning misalignment or unstable connection. Furthermore, long-term use or frequent disassembly / reassembly may cause magnet demagnetization, gradually weakening the attraction force and affecting long-term reliability. To address this issue, in this application, the main speaker 1 and auxiliary speaker 2 of the combined wireless speaker are assembled using a connecting mechanism 3. The connecting sockets 4 at both ends of the main speaker 1 contain guide blocks 5 and guide rods 8. Limiting blocks 6 are slidably mounted on the guide blocks 5, and the limiting blocks 6 slide against the guide blocks 5 via bottom guide grooves 7. The limiting blocks 6 have a first guide slope on their outer side and a guide slot 9 corresponding to the guide rod 8 inside. A return spring mounted on the guide rod 8 constantly applies downward pressure to the limiting blocks 6. A second guide ramp is provided on the outer side of the connecting plug 10 of the auxiliary speaker 2. When the two are connected, the first and second guide ramps contact each other and generate a component force. As the plug is continuously inserted, the interaction of the ramps pushes the limiting block 6 upward along the guide block 5. At this time, the return spring is compressed and stored, and the guide rod 8 forms a vertical limit in the guide slot 9 of the limiting block 6. When the connecting plug 10 is fully inserted into the connecting socket 4 and reaches the predetermined position, the first guide ramp of the limiting block 6 disengages, the return spring pushes the limiting block 6 downward along the guide block 5, and the limiting block 6 is locked into the corresponding position of the connecting plug 10, forming a horizontal mechanical lock. During disassembly, the limiting block 6 is pulled up by external force to disengage it from the connecting plug 10, and the return spring is compressed again to release the connecting plug 10, thus realizing the separation of the auxiliary speaker 2 from the main speaker 1. This mechanism achieves the dual functions of quick insertion and removal and automatic locking through the cooperation of the ramp guide and the spring return.

[0029] Reference Figures 1-4 As shown: The main speaker 1 has a connection socket 4 and a connection plug 10 at its two ends, respectively. The auxiliary speaker 2, which is installed at one end of the connection socket 4, is provided with a connection plug 10, and the auxiliary speaker 2, which is installed at one end of the connection plug 10, is provided with a connection socket 4.

[0030] The two ends of the main speaker 1 are designed with two different connection interfaces: a connection socket 4 and a connection plug 10. One end connects to the connection plug 10 of the auxiliary speaker 2 through the connection socket 4, while the other end connects to the connection socket 4 of the other auxiliary speaker 2 through its own connection plug 10.

[0031] Reference Figures 1-7 As shown: The limiting block 6 is provided with an auxiliary gripper 11 for the operator to hold.

[0032] The auxiliary gripper 11 added to the limiting block 6 provides the operator with a point of force for manual operation. Its structure is usually a concave or convex anti-slip texture design. When it is necessary to disassemble the auxiliary speaker box 2, the operator can grasp the auxiliary gripper 11 with his / her fingers to directly apply an upward lifting force to the limiting block 6, overcome the elastic force of the return spring, and make the limiting block 6 slide along the guide block 5 to disengage from the limiting state of the connecting plug 10.

[0033] Reference Figures 1-5 As shown: The main speaker 1 is provided with a guide rail 12 on the top, and the auxiliary speaker 2 is provided with a groove 13 at the bottom that is adapted to the guide rail 12.

[0034] When the auxiliary speaker 2 needs to be installed on top of the main speaker 1, the operator aligns the slide groove 13 at the bottom of the auxiliary speaker 2 with the guide rail 12 and pushes it horizontally. The cooperation between the rail and the slide groove 13 forms a lateral movement constraint, ensuring that the auxiliary speaker 2 slides along the preset path to the target position.

[0035] Reference Figures 1-7 As shown: The connecting plug 10 of the auxiliary speaker 2 can be inserted into the connecting socket 4 on another auxiliary speaker 2, and the two auxiliary speakers 2 are combined together on the guide rail 12 by the cooperation of the connecting plug 10 and the connecting socket 4.

[0036] After the slide groove 13 at the bottom of the auxiliary speaker 2 matches the guide rail 12 at the top of the main speaker 1, the auxiliary speaker 2 can be initially positioned on top of the main speaker 1 by horizontal sliding. When the two auxiliary speakers 2 need to be connected to each other on the guide rail 12, the connecting plug 10 of one auxiliary speaker 2 needs to be aligned with the connecting socket 4 of the other auxiliary speaker 2. When the connecting plug 10 is fully inserted into the connecting socket 4, the limiting block 6 is reset under the action of the return spring, locking the connecting plug 10 to complete the vertical fixation.

[0037] Reference Figures 1-6 As shown: The guide rail 12 has a fixed insertion hole 14 in the slide groove 13 at the bottom of the auxiliary speaker box 2. When the two auxiliary speakers 2 are combined together, and the fixed insertion hole 14 in the slide groove 13 of the auxiliary speaker box 2 coincides with the fixed insertion hole 14 on the side of the guide rail 12, a fixed pin 15 is inserted into the fixed insertion hole 14.

[0038] The guide rail 12 has a pre-set fixing hole 14 on its side and in the slide groove 13 at the bottom of the auxiliary speaker 2. When the auxiliary speaker 2 slides along the rail to the combined position, the fixing holes 14 of the two speakers overlap to form a through channel. After the two auxiliary speakers 2 are vertically locked to the socket by the connecting plug 10, the operator inserts the fixing pin 15 into the overlapping fixing hole 14. The pin passes through the side wall of the rail and the inner wall of the slide groove 13, forming a horizontal mechanical limit.

[0039] Reference Figure 5 and Figure 6As shown: The fixing pin 15 is magnetically attached to the fixing socket 14.

[0040] The guide rail 12 and the fixing socket 14 in the slide groove 13 of the auxiliary speaker 2 are made of magnetic material or have embedded magnets. The fixing pin 15 also contains magnetic components on its surface or inside. When the auxiliary speaker 2 slides to the combined position and the fixing socket 14 is aligned, the operator brings the fixing pin 15 close to the fixing socket 14, and the magnetic force automatically attracts and guides the fixing pin 15 to be accurately inserted into the fixing socket 14.

[0041] Reference Figure 5 As shown: One end of the fixed pin 15 is provided with a sliding groove 16 for easy insertion and removal by the operator.

[0042] The operator removes the fixing pin 15 from the fixing socket 14 by using the sliding groove 16.

[0043] Working Principle: In the modular wireless speaker, the main speaker 1 and the auxiliary speaker 2 are assembled via a connecting mechanism 3. The main speaker 1 has guide blocks 5 and guide rods 8 inside the connecting sockets 4 at both ends. Limiting blocks 6 are slidably mounted on the guide blocks 5, forming a sliding fit with them via bottom guide grooves 7. The outer side of the limiting block 6 has a first guide slope, and the inner side has a guide slot 9 corresponding to the guide rod 8. A return spring mounted on the guide rod 8 constantly applies downward pressure to the limiting block 6. The auxiliary speaker 2 has a second guide slope on the corresponding position on the outer side of the connecting plug 10. When the two are connected, the first and second guide slopes contact each other, generating a component force. As the plug is continuously inserted, the interaction of the slopes pushes the limiting block 6 upward along the guide block 5. At this time, the return spring is compressed and stores energy, and the guide rod 8 forms a vertical limit within the guide slot 9 of the limiting block 6. When the connecting plug 10 is fully inserted into the connecting socket 4 and reaches the predetermined position, the first guide slope of the limiting block 6 disengages from contact, and the return spring pushes the limiting block 6 downward along the guide block 5 to reset. The limiting block 6 then engages with the corresponding position of the connecting plug 10, forming a horizontal mechanical lock, thus achieving the installation and fixation of the auxiliary speaker 2 and the main speaker 1. During disassembly, the operator can directly apply an upward pulling force to the limiting block 6 through the auxiliary gripper 11 on the limiting block 6, overcoming the elastic force of the return spring, causing the limiting block 6 to slide along the guide block 5 and disengage from the limiting state of the connecting plug 10, thereby separating the auxiliary speaker 2 from the main speaker 1. The auxiliary gripper 11 is usually designed with concave or convex anti-slip textures, providing the operator with a point of force for manual operation.

[0044] The main speaker 1 has two different connection interfaces at its two ends: a connection socket 4 and a connection plug 10. One end connects to the connection plug 10 of the auxiliary speaker 2 through the connection socket 4, while the other end connects to the connection socket 4 of another auxiliary speaker 2 through its own connection plug 10, so as to realize the combination installation of the main speaker 1 and different auxiliary speakers 2.

[0045] When the auxiliary speaker 2 needs to be installed on top of the main speaker 1, the operator aligns the groove 13 at the bottom of the auxiliary speaker 2 with the guide rail 12 at the top of the main speaker 1 and pushes it horizontally. The cooperation between the rail and the groove 13 forms a lateral movement constraint, ensuring that the auxiliary speaker 2 slides along the preset path to the target position. After the groove 13 at the bottom of the auxiliary speaker 2 matches the guide rail 12 at the top of the main speaker 1, the auxiliary speaker 2 can be initially positioned on top of the main speaker 1 by horizontal sliding. When the two auxiliary speakers 2 need to be connected to each other on the guide rail 12, the connecting plug 10 of one auxiliary speaker 2 needs to be aligned with the connecting socket 4 of the other auxiliary speaker 2. When the connecting plug 10 is fully inserted into the connecting socket 4, the limiting block 6 is reset under the action of the return spring, locking the connecting plug 10 to complete the vertical fixation.

[0046] Fixed insertion holes 14 are provided in the slide groove 13 on the side of the guide rail 12 and the bottom of the auxiliary speaker box 2. When the two auxiliary speakers 2 are combined together and the fixed insertion hole 14 in the slide groove 13 of the auxiliary speaker box 2 coincides with the fixed insertion hole 14 on the side of the guide rail 12, the operator inserts the fixed pin 15 into the coincident fixed insertion hole 14. The pin passes through the side wall of the rail and the inner wall of the slide groove 13, forming a horizontal mechanical limit. The fixed insertion hole 14 on the side of the guide rail 12 and the slide groove 13 of the auxiliary speaker box 2 is made of magnetic material or has an embedded magnet design. The surface or interior of the fixed pin 15 also contains magnetic components. When the auxiliary speaker box 2 slides to the combined position and the fixed insertion hole 14 coincides, the operator brings the fixed pin 15 close to the fixed insertion hole 14. The magnetic force automatically attracts and guides the fixed pin 15 to be accurately inserted into the fixed insertion hole 14. One end of the fixed pin 15 has a tug groove 16 for easy insertion and removal by the operator, making it convenient for the operator to remove the fixed pin 15 from the fixed insertion hole 14.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
