[0024] Example Please refer to the following: Figure 1 and Figure 2 This embodiment provides a magnetic induction knob audio device, specifically a portable magnetic induction knob audio device. The magnetic induction knob audio device includes a housing assembly 100, an audio assembly 200, a magnetic induction assembly 300, a bearing 400, a knob assembly 500, a magnetic component 600, and an elastic component 700.

[0025] The housing assembly 100 includes a housing body 110 and a fixed bushing 120, with one end of the fixed bushing 120 connected to the housing body 110 along its own axis.

[0026] The audio component 200 is housed inside the housing component 100. The audio component 200 includes an audio output terminal 210, which is inserted into the fixed bushing 120. The magnetic sensing component 300 is disposed inside the housing body 110 and is electrically connected to the audio component 200.

[0027] Bearing 400 is fitted onto fixed bushing 120. Knob assembly 500 is fitted onto bearing 400, and the inner wall of knob assembly 500 is provided with multiple grooves 522 (see...). Figure 6 Multiple grooves 522 are arranged circumferentially along the fixed bushing 120.

[0028] In addition, a magnetic component 600 is provided in the knob assembly 500 and corresponds to the magnetic sensing component 300.

[0029] The elastic element 700 is disposed on the outer wall of the fixed bushing 120 and corresponds to the groove 522. The elastic element 700 can elastically deform along the radial direction of the fixed bushing 120.

[0030] When using the aforementioned magnetic induction knob audio device, the user keeps the outer casing assembly 100 stationary and rotates the knob assembly 500, causing the magnetic component 600 to rotate, thus changing the magnetic field at the location of the magnetic induction component 300. The magnetic induction component 300 senses the change in the magnetic field and outputs a signal to the audio component 200, thereby adjusting the audio played by the audio component 200. During the adjustment process, multiple grooves 522 on the inner wall of the knob assembly 500 alternately misalign or align with the elastic component 700. When all grooves 522 are misaligned with the elastic component 700, the elastic component 700 is compressed and deformed along the radial direction of the fixed bushing 120, applying resistance to the rotation of the knob assembly 500; when any groove 522 aligns with the elastic component 700, the elastic component 700 returns to its original position. Thus, the elastic component 700, in cooperation with the multiple grooves 522, can provide the knob assembly 500 with delicate mechanical feedback, improving the product's interactive performance. In the aforementioned magnetic induction knob audio device, the audio output terminal 210 is inserted into the fixed bushing 120, the fixed bushing 120 passes through the bearing 400, and the knob assembly 500 is sleeved on the bearing 400. This fully utilizes the hollow interior of the bearing 400, simultaneously realizing the functions of audio output in a small space and a hollow shaft knob, thereby further reducing the overall size of the magnetic induction knob audio device, which is conducive to the miniaturization of the device and makes it more portable.

[0031] Please refer to the following: Figure 2 and Figure 3 In some embodiments, the audio component 200 further includes a motherboard 220 and a battery 230. The motherboard 220 and the battery 230 are both housed inside the housing body 110, and the motherboard 220 is electrically connected to the audio output terminal 210, the battery 230, and the magnetic sensing component 300, respectively.

[0032] In use, battery 230 supplies power to motherboard 220, which outputs audio through audio output terminal 210. When magnetic sensing component 300 senses a change in magnetic field, it outputs a signal to motherboard 220, which then controls the audio output from audio output terminal 210.

[0033] For example, the audio output terminal 210 is a 3.5mm headphone jack for headphone connection. In addition, the motherboard 220 is a PCB board.

[0034] For example, adjusting audio can be done by adjusting the audio volume.

[0035] Furthermore, in some embodiments, the housing assembly 100 further includes a bottom cover 130 connected to the end of the housing body 110 away from the fixed bushing 120.

[0036] Accordingly, the audio component 200 also includes a charging dock 240. The charging dock 240 is electrically connected to the motherboard 220 and is inserted into the bottom cover 130.

[0037] When in use, the battery 230 can be charged through the charging circuit on the charging dock 240 and the motherboard 220.

[0038] For example, the outer casing 110 is cylindrical, and the axis of the outer casing 110 coincides with the axis of the fixed bushing 120. The outer casing 110 has an external thread at one end near the fixed bushing 120 along its own axis, and the fixed bushing 120 has a corresponding internal thread, and the outer casing 110 and the fixed bushing 120 are threadedly connected.

[0039] In addition, a recessed groove 111 is provided at one end of the outer shell body 110 away from the fixed bushing 120 along its own axis, and the bottom cover 130 is embedded and fixed in the recessed groove 111.

[0040] For example, the charging dock 240 uses a Type-C interface.

[0041] Please see Figure 4 In some embodiments, the magnetic sensing component 300 is fixed to the inner wall end face of the fixed bushing 120 facing the outer casing 110 by adhesive backing, and a magnetic sensing chip 310 is disposed on the magnetic sensing component 300. The magnetic sensing chip 310 is electrically connected to the motherboard 220 by wire bonding, thereby realizing communication.

[0042] For example, the magnetic sensing component 300 may employ a Hall sensor.

[0043] Please see Figure 5 In some embodiments, the outer wall of the fixed bushing 120 is provided with a stepped portion 121, and the bearing 400 contacts the stepped portion 121.

[0044] Understandably, the step portion 121 can position the bushing, which is beneficial for the precise assembly and fixation of the bushing 120 and the bearing 400.

[0045] For example, the inner wall of the bearing 400 is interference-fitted with the outer wall of the fixed bushing 120, so that the inner ring of the bearing 400 is fixedly connected to the fixed bushing 120.

[0046] Please see Figure 6In some embodiments, the knob assembly 500 includes a knob body 510 and a top cover 520.

[0047] The knob body 510 is sleeved on the bearing 400, and the magnetic component 600 is disposed on the inner wall of the knob body 510. The top cover 520 is connected to the end of the knob body 510 away from the outer shell body 110, and the inner wall of the top cover 520 is provided with multiple grooves 522.

[0048] In use, the knob body 510 is rotatably connected to the fixed bushing 120 via the bearing 400. When the user rotates the knob body 510, the magnetic component 600 and the top cover 520 rotate synchronously, causing a change in the magnetic field at the location of the magnetic sensing component 300, and causing the various grooves 522 to alternately misalign or align with the elastic component 700.

[0049] For example, the knob body 510 has an internal thread at one end near the top cover 520, and the top cover 520 has an external thread, and the knob body 510 and the top cover 520 are threadedly connected.

[0050] For example, the magnetic component 600 is a ring magnet. The outer wall of the magnetic component 600 is interference-fitted with the inner wall of the knob body 510, so that the magnetic component 600 is fixedly connected to the knob body 510.

[0051] Similarly, the outer wall of the bearing 400 is also interference-fitted with the inner wall of the knob body 510, so that the outer ring of the bearing 400 is fixedly connected to the knob body 510.

[0052] Please refer to the following: Figure 6 , Figure 7 and Figure 8 Furthermore, in some embodiments, the inner wall of the knob body 510 is provided with a protrusion 511, the protrusion 511 including an outer stop surface 512 facing the top cover 520 and an inner stop surface 513 facing away from the top cover 520.

[0053] Accordingly, the bearing 400 contacts the outer stop surface 512, and the magnetic component 600 contacts the inner stop surface 513.

[0054] Understandably, the protrusion 511 can position the bearing 400 and the magnetic component 600 respectively, which is beneficial for the precise assembly and fixation of the knob body 510 and the bearing 400, and the knob body 510 and the magnetic component 600.

[0055] Furthermore, in some embodiments, the inner wall of the top cover 520 is provided with a toothed ring 521, which includes a plurality of grooves 522.

[0056] Specifically, the gear ring 521 consists of multiple teeth, with a groove 522 formed between any two adjacent teeth. As the top cover 520 rotates, the teeth and grooves 522 alternately align with the elastic element 700. When any tooth aligns with the elastic element 700, the elastic element 700 compresses and deforms along the radial direction of the fixed bushing 120, applying resistance to the rotation of the knob assembly 500. When any groove 522 aligns with the elastic element 700, the elastic element 700 returns to its original position.

[0057] For example, the toothed ring 521 includes 24 teeth and 24 grooves 522. With each rotation of the top cover 520, the toothed ring 521 engages with the elastic element 700, providing 24 tactile feedbacks.

[0058] It should be noted that the correspondence between the elastic element 700 and the groove 522 means that the orthographic projections of the elastic element 700 and the groove 522 on the axis of the fixed bushing 120 are aligned.

[0059] Please see Figure 9 In some embodiments, the elastic element 700 is a spring ring. Part of the spring ring is bent outward to form an outer spring ring 710, which corresponds to the groove 522.

[0060] Understandably, each tooth and each groove 522 alternately aligns with the elastic element 700, specifically meaning that each tooth and each groove 522 alternately aligns with the outer ring 710 of the spring, and the outer ring 710 of the spring is compressed and deformed when aligned with the tooth, and reset when aligned with the groove 522.

[0061] Furthermore, in some embodiments, the aforementioned magnetic induction knob audio device further includes a spring retainer 800. The spring retainer 800 is sleeved on the fixed bushing 120, and a positioning post 810 is provided on the spring retainer 800, extending along the axial direction of the fixed bushing 120.

[0062] Accordingly, a spring ring is fitted onto the spring fixing member 800. Part of the spring ring is bent inward to form an inner spring ring 720, which is fitted onto the positioning post 810.

[0063] During assembly, the spring retainer 800 is fixedly connected to the outer wall of the fixed bushing 120, and the spring ring is set on the outer wall of the fixed bushing 120 through the spring retainer 800. Among them, the inner spring ring 720 is sleeved on the positioning post 810, which can keep the spring ring and the spring retainer 800 relatively fixed.

[0064] For example, the inner wall of the spring retainer 800 is interference-fitted with the outer wall of the fixed bushing 120, so that the spring retainer 800 and the fixed bushing 120 are fixedly connected.

[0065] Furthermore, in some embodiments, the spring retainer 800 is provided with a clearance opening 820. The clearance opening 820 corresponds to the outer ring 710 of the spring, that is, the clearance opening 820 and the outer ring 710 of the spring are aligned along the radial direction of the fixed bushing 120.

[0066] When the outer ring 710 of the spring is aligned with the tooth, the outer ring 710 of the spring deforms inward. At this time, the clearance 820 on the spring fixing can avoid the outer ring 710 of the spring, ensuring that the outer ring 710 of the spring deforms smoothly.

[0067] In the aforementioned magnetic induction knob audio device, the audio output terminal 210 is inserted into the fixed bushing 120, which passes through the bearing 400. The knob assembly 500 is fitted onto the bearing 400. This fully utilizes the hollow interior of the bearing 400, simultaneously achieving audio output in a small space and the function of a hollow shaft knob. This further reduces the overall size of the magnetic induction knob audio device, facilitating miniaturization and making the device more portable. In particular, the bearing 400 has better circumferential motion load-bearing capacity, uniform force distribution along the circumference, higher reliability, and longer lifespan.

[0068] Furthermore, the aforementioned magnetic induction knob audio device utilizes the deformation properties of springs, employing a spring ring as the elastic element 700, which, in conjunction with the toothed ring 521, provides a delicate mechanical feedback to the knob body 510, improving the product's interactive performance. The magnetic induction knob audio device, utilizing magnetic induction technology, simplifies structural design and reduces mechanical wear.

[0069] In summary, the aforementioned magnetic induction knob audio devices are small in size, simple and reliable in structure, low in cost, and have a long service life.

[0070] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0071] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0072] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. 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 modifications and improvements all fall within the protection scope of this utility model.
