Description

Technical Field

[0001] This utility model relates to the field of intelligent control and audio playback technology, specifically an inductive sound playback controller. Background Technology

[0002] A sound playback controller is a device used to control the sound output of audio equipment, widely used in smart homes, exhibitions, and public facilities. With the development of IoT technology and the diversification of user needs, the functionality and convenience requirements of sound playback controllers are gradually increasing. Currently, the market offers a wide variety of sound playback controllers with diverse operation methods, including button-type, remote control-type, sensor-type, and touch-type.

[0003] An investigation revealed that a Chinese utility model patent discloses an inductive sound playback controller (publication number: CN211203535U), comprising a controller body mounted on a wall. The right end of the wall has a controller placement groove, the inner left end of which has a locking groove, and the inner left end of which has a suction cup placement groove. A suction cup is fixedly connected to the inner bottom of the suction cup placement groove. Both the upper and lower ends of the locking groove have compression spring placement grooves, and compression springs are fixedly connected to the inner bottom of each pair of compression spring placement grooves. Telescopic tubes are fitted over the outer ends of each pair of compression springs. A hemispherical magnetic block and a first rubber ball sleeve are fixedly connected to the adjacent ends of each pair of compression springs. The first rubber ball sleeve is fixedly fitted over the outer end of the hemispherical magnetic block. The two ends of the telescopic tubes are fixedly connected to the bottom end of the compression spring placement groove and the first rubber ball sleeve, respectively. This design allows for effective installation and provides a certain degree of protection after installation.

[0004] Although the aforementioned patent allows for quick installation of the sound playback controller through the use of a compression spring, telescopic tube, and rubber ball sleeve, the sound playback controller connects to terminal devices or other electronic devices via a data cable during use. The patent does not allow for adjustment of the data cable length. If the data cable is too long, it is easy for it to get tangled and knotted, while if the data cable is too short, it cannot be used in various scenarios, thus reducing the applicability of the sound playback controller.

[0005] Therefore, this utility model provides an inductive sound playback controller to solve the above problems. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides an inductive sound playback controller, combined with the attached... Figure 1 To be continued Figure 6 As shown, this controller achieves intelligent audio control and data cable length adjustment through the collaborative work of multiple functional modules. The following section provides a detailed explanation of its implementation method in conjunction with its specific structure and operating principle.

[0029] The main body 1 of the sound playback controller is the core part of the device. It integrates a sensing window 2, a sensor 3, a signal processor 6, and a physical switch 7. The sensing window 2 is located on one side of the main body 1 of the sound playback controller and is used to receive signals from the external environment and transmit them to the sensor 3. The sensor 3 includes an infrared sensor 4 and a microwave sensor 5. The infrared sensor 4 is closer to the sensing window 2 and is mainly used to detect human body heat radiation signals. The microwave sensor 5 is closer to the infrared sensor 4 and is used to detect human body movement signals. The signal processor 6 is away from the sensor 3. Its built-in algorithm module processes the received signals, generates control commands, and sends the commands to the audio device to realize sound playback control. The physical switch 7 is away from the signal processor 6 and is used to manually start or stop the device or switch modes.

[0030] In practical use, when a human body enters the sensing range, the infrared sensor 4 first detects the thermal radiation signal emitted by the human body and transmits the signal to the signal processor 6. Subsequently, the microwave sensor 5 detects the human body's motion signal and superimposes the signal to the signal processor 6. The signal processor 6 determines whether the human body is truly close to the controller based on parameters such as the received signal strength, frequency, and time interval, and generates corresponding control commands accordingly. For example, when the signal processor 6 determines that the human body is close and stays for more than a preset time, the controller will automatically start the audio device and play preset content. Conversely, if the human body leaves the sensing range for more than a set time, the controller will stop playing audio. In addition, the signal processor 6 also has a self-learning function, which can gradually optimize the sensing sensitivity and response speed according to the user's usage habits, thereby improving the user experience.

[0031] To facilitate connection with other devices, a data cable connector 8 is inserted into one side of the main body 1 of the sound playback controller. A data cable 9 is fixedly connected to one side of the data cable connector 8, and a data cable plug 11 is fixedly connected to one end of the data cable 9. An adjustment component 10 is provided on the outer wall of the data cable 9 to solve the problem that the length of the data cable cannot be flexibly adjusted in the prior art. Figure 3 and attached Figure 4 As shown, the adjustment component 10 includes a first adjustment block 12, a second adjustment block 15, a third adjustment block 16, a fourth adjustment block 17, and a fifth adjustment block 18. Magnetic posts 13 are fixedly connected inside the four corners of these adjustment blocks. The magnetic posts 13 connect the adjustment blocks to each other through magnetic force, forming a detachable integral structure. The attraction and separation of the adjustment blocks are used to extend or rewind the data connection line 9, thereby extending or folding the data connection line 9 and changing its length to suit different usage scenarios.

[0032] Each adjusting block has a guide groove 19 inside that matches the data connection cable 9. The data connection cable 9 is slidably connected inside the guide groove 19. The design of the guide groove 19 not only guides the movement of the data connection cable 9, but also enhances the positioning accuracy through the internal elastic balls 20. The elastic balls 20 are evenly distributed on the inner wall of the guide groove 19, and their surfaces contact the outer wall of the data connection cable 9, forming a moderate friction force to prevent the data connection cable 9 from sliding randomly in the guide groove 19. The number and distribution density of the elastic balls 20 are precisely designed to ensure the stability of the data connection cable. The smooth movement of the data cable 9 within the guide groove 19 prevents damage to the data cable due to excessive friction or failure of length adjustment due to insufficient friction. In addition, flexible rings 14 are fixedly connected to both sides of the first adjusting block 12, the second adjusting block 15, the third adjusting block 16, the fourth adjusting block 17, and the fifth adjusting block 18. The flexible rings 14 are made of polymer material and have good flexibility and wear resistance. The inner wall of the flexible rings 14 fits tightly against the outer wall of the data cable 9, playing a protective and positioning role, effectively preventing the data cable 9 from being worn or deformed during the adjustment process.

[0033] The bottom of the main body 1 of the sound playback controller is provided with a fixing component 21, which includes a connecting plate 22, a pressing post 23, and a vacuum suction cup 24. The connecting plate 22 is fixedly connected to the bottom of the main body 1 of the sound playback controller, and the pressing post 23 is fixedly connected to the bottom of the pressing post 23. The vacuum suction cup 24 is fixedly connected to the bottom of the pressing post 23. In the actual installation process, the user only needs to align the vacuum suction cup 24 with the flat surface and apply appropriate pressure, and the vacuum suction cup 24 will firmly adhere to the flat surface, realizing the quick fixation of the sound playback controller. This design simplifies the installation process of the controller, while ensuring the stability of the controller during use. It is suitable for various installation environments. For example, in exhibition scenarios, users can quickly fix the controller to the exhibition stand or wall; in smart home scenarios, users can fix the controller to a desktop or other flat surface for convenient daily use.

[0034] The top of the main body 1 of the sound playback controller is equipped with an indicator light 25. The indicator light 25 is connected to the output terminal of the signal processor 6 via a wire and is used to display the working status of the device. The indicator light 25 uses an LED light source, and its brightness and color can be adjusted according to the output signal of the signal processor 6. For example, when the device is in standby mode, the indicator light 25 displays a solid blue light; when the device detects a human body approaching and is ready to play audio, the indicator light 25 displays a flashing green light; when the device is playing audio, the indicator light 25 displays a solid red light. In this intuitive way, users can understand the operating status of the device in real time, enhancing the interactive experience.

[0035] Combined with appendix Figure 6 As shown, the sensing process of this utility model is as follows: S1 After the infrared sensor 4 detects the human body's thermal radiation signal, it transmits the signal to the signal processor 6; S2 After the microwave sensor 5 detects the human body's movement signal, it superimposes the signal and transmits it to the signal processor 6; S3 The signal processor 6 analyzes and processes the received signal to determine whether the human body has entered the sensing range; S4 If it is determined that the human body has entered the sensing range, the signal processor 6 generates a control command and sends it to the audio device; S5 After receiving the control command, the audio device starts playing preset content; S6 If the human body leaves the sensing range for more than a set time, the signal processor 6 stops sending control commands, and the audio device stops playing content.

[0036] In practical applications, the inductive sound playback controller of this invention can be widely used in smart homes, exhibitions, and public facilities. For example, in a smart home scenario, the user can fix the controller on the wall of the living room or bedroom, and the controller will automatically play background music or voice prompts when someone enters the room. In an exhibition scenario, the controller can be fixed near the exhibits, and the controller will automatically play relevant introductory content when visitors approach the exhibits. In a public facility scenario, the controller can be installed in elevators or corridors, and the controller will automatically play safety reminders or welcome messages when someone passes by. Through the above applications, this invention not only improves the intelligence level of audio equipment but also significantly enhances the user's convenience and experience.

[0037] In summary, this utility model solves the problems existing in the prior art through reasonable structural design and functional optimization. The design of the adjustment component 10 enables flexible adjustment of the data cable length, significantly improving the applicability and convenience of the device. The elastic ball 20 and flexible ring 14 set inside the guide groove 19 enhance the positioning accuracy of the data connection cable 9 and extend the service life of the data cable. The collaborative work of the infrared sensor 4 and the microwave sensor 5, combined with the intelligent algorithm of the signal processor 6, improves the sensing sensitivity and response speed of the device. The design of the vacuum suction cup 24 in the fixing component 21 enables the controller to be quickly adsorbed and fixed on the plane, which is simple to operate and highly stable. The design of the indicator light 25 can intuitively display the working status of the device, enhancing the user's interactive experience. Therefore, this utility model has high practicality and market promotion value.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
