[0032] The traditional volume control methods mainly include mechanical keys and touch panels. The touch panel has a simple appearance and a strong sense of technology, but since the touch panel is a plane without obvious physical boundaries, it lacks tactile feedback, and if the user is slightly careless during operation, other areas may be mistakenly touched, resulting in volume adjustment errors, and even triggering other unnecessary functions. Although the mechanical key is intuitive to operate, when the key is pressed, noise interference is easily generated, especially when the key is arranged near the earpiece, which seriously affects the user experience.
[0033] Therefore, the volume adjustment structure of the utility model adopts a mechanical dial mode, rotates the dialing part to different positions relative to the circuit board to turn on the first circuit for controlling volume increase or the second circuit for controlling volume decrease, triggers the program for controlling volume increase and decrease, and thus realizes the adjustment of the volume. Based on the structure design of the rotating contact, the user only needs to slightly dial the dialing part to the corresponding position by the finger, and the volume adjustment operation can be completed. Compared with the touch panel key, the dial volume adjustment structure of the utility model has tactile feedback and is not easy to cause mistaken triggering; compared with the traditional mechanical key, the dial volume adjustment structure of the utility model can reduce the noise generated by the key.
[0034] The scheme of the utility model will be described in detail below in combination with the drawings.
[0035] Embodiment 1
[0036] Figures 1-6 The specific structure of the first embodiment of the volume adjustment structure of the utility model is shown. As shown in Figures 1-2 The volume adjustment structure includes a shell 10, a circuit board 20 arranged in the inner cavity of the shell 10, and a volume adjustment assembly 30.
[0037] The housing 10 is generally rectangular with rounded corners, and its internal cavity houses a circuit board 20. The circuit board 20 integrates a first circuit for controlling volume increase and a second circuit for controlling volume decrease.
[0038] Volume control assembly 30 includes a toggle 300 and a pivot 304, such as Figure 3 As shown, the actuating member 300 consists of two parts: a disc-shaped operating part 3001 and a rectangular selection part 3002. The operating part 3001 has a rotating hole 3001b at its center for a rotating shaft 304 to pass through. The rotating shaft 304 is specifically a screw shaft; by screwing, the rotating shaft 304, passing through the rotating hole 3001b, can be fixed to the housing 10 and perpendicular to the circuit board 20. The actuating member 300 is positioned opposite the circuit board 20, and can move circumferentially around the rotating shaft 304 relative to the side of the circuit board 20. A groove 100 extending circumferentially is provided at one rounded corner of the housing 10. The operating part 3001 of the actuating member 300 extends out of the outside of the housing 10 from the groove 100 and can move within the groove 100. Figure 4 As shown, the selection part 3002 of the toggle member 300 is provided with a conductive spring 302. The connection between the conductive spring 302 and the selection part 3002 of the toggle member 300 can be a fixed connection or a connection as shown in the figure. Figure 4 The connection is made using a snap-fit or other detachable method. For example... Figure 5 As shown, the conductive spring 302 is generally in the shape of a nested ring, consisting of a first conductive part 3021 in the middle, a second conductive part 3022 on the outside, and a third conductive part 3023 on the inside, and the first conductive part 3021, the second conductive part 3022, and the third conductive part 3023 are interconnected. The first conductive part 3021, the second conductive part 3022, and the third conductive part 3023 are respectively provided with a first conductive bump 3021a, a second conductive bump 3022a, and a third conductive bump 3023a. The circuit board 20 has an electrode assembly on the side facing the toggle member 300, including a first electrode 201, a second electrode 202, and a third electrode 203. The first electrode 201, the second electrode 202, and the third electrode 203 are respectively positioned on the movement path of the first conductive bump 3021a, the second conductive bump 3022a, and the third conductive bump 3023a relative to the circuit board 20 in a circumferential motion. Specifically, the first electrode 201 and the second electrode 202 are electrically connected to a first circuit for controlling volume increase, and the first electrode 201 and the third electrode 203 are electrically connected to a second circuit for controlling volume decrease. Of course, the above electrical connections can be adjusted as needed, i.e., the first electrode 201 and the second electrode 202 are electrically connected to the first circuit, and the first electrode 201 and the third electrode 203 are electrically connected to the second circuit.
[0039] like Figure 1As shown, the first electrode 201 is in a long strip shape, and the second electrode 202 and the third electrode 203 are respectively located at positions close to the end portions of the opposite ends of the first electrode 201 along the extending direction thereof. The length of the first electrode 201 is greater than the sum of the lengths of the second electrode 202 and the third electrode 203, so that when the actuating member 300 moves circumferentially around the rotation shaft 304, the first conductive bump 3021a is always in contact with the first electrode 201. When the operation portion 3001 of the actuating member 300 is rotated in the first rotation direction D1, the second conductive bump 3022a on the selection portion 3002 is driven to rotate in the same direction to a position in contact with the second electrode 202, but at this position, the third conductive bump 3023a is not in contact with the third electrode 203, so that the first circuit is turned on, and the second circuit is in an open state. Similarly, when the operation portion 3001 of the actuating member 300 is rotated in the second rotation direction D2, the third conductive bump 3023a on the selection portion 3002 is driven to rotate in the same direction to a position in contact with the third electrode 203, but at this position, the second conductive bump 3022a is not in contact with the second electrode 202, so that the second circuit is turned on, and the first circuit is in an open state. After the first circuit is turned on, an adjustment signal for increasing the volume is triggered, and the adjustment signal is transmitted to the integrated circuit for processing, so as to control the volume to increase step by step. After the second circuit is turned on, an adjustment signal for decreasing the volume is triggered, and the adjustment signal is processed by the integrated circuit, so as to control the volume to decrease step by step.
[0040] Before adjusting the volume, the selection part 3002 of the dial 300 is located at the third position, at this time, only the first conductive bump 3021a is in contact with the first electrode 201, the second conductive bump 3022a and the third conductive bump 3023a are not in contact with the corresponding second electrode 202 and third electrode 203. When the volume needs to be increased, the operation part 3001 of the dial 300 is rotated in the first rotation direction D1 to drive the selection part 3002 to rotate in the same direction to the second conductive bump 3022a in contact with the second electrode 202, so as to turn on the first circuit for controlling the volume increase. After the first circuit is turned on, the volume is gradually increased by the control program of the software (one level is usually 20% of the volume), when the volume reaches the target volume, the operation part 3001 is rotated in the second rotation direction D2 to make the selection part 3002 return from the first position to the third position, and the volume adjustment is completed. Similarly, when the volume needs to be reduced, the operation part 3001 of the dial 300 is rotated in the second rotation direction D2 to drive the selection part 3002 to rotate in the same direction to the third conductive bump 3023a in contact with the third electrode 203, so as to turn on the second circuit for controlling the volume reduction. After the second circuit is turned on, the volume is gradually reduced by the control program of the software, when the volume reaches the target volume, the operation part 3001 is rotated in the first rotation direction D1 to make the selection part 3002 return from the second position to the third position, and the volume adjustment is completed. It should be noted that the integrated circuit controls the volume to gradually increase or decrease according to the received volume increase or decrease adjustment signal, which belongs to the prior art, and this technology is not the focus of the present application, so it will not be described in detail here.
[0041] In the above volume adjustment structure, the shell 10 can also have other shapes, and the sliding groove 100 can also be arranged at other positions of the shell 10 as needed, which is not limited here.
[0042] When the above volume adjustment structure is used to adjust the volume, the second conductive bump 3022 may be separated from the second electrode 202 or the third conductive bump 3023 may be separated from the third electrode 203 due to the amplitude of the dial 300 being operated in one of the rotation directions being too large. In order to avoid this situation, a limiting column 102 is arranged on the relative two sides of the movement direction of the dial 300 in the shell 10, both limiting columns 102 are located on the movement path of the selection part 3002 of the dial 300 and are located on the outside of the electrode assembly, so as to limit the rotation amplitude of the selection part 3002 from both sides, and avoid the first conductive bump 3021a, the second conductive bump 3022 and the third conductive bump 3023a from being separated from the corresponding first electrode 201, second electrode 202 and third electrode 203.
[0043] Further, the operation part 3001 of the dial member 300 is provided with convex or concave patterns to form a surface with convex and concave patterns, which on one hand increases the friction between the fingers of the user and the operation part 3001, and on the other hand facilitates the positioning and distinguishing of the operation of the fingers, and improves the hand feeling and the convenience of operation.
[0044] To facilitate the identification of the position of the selection part 3002 of the dial member 300, the position of the operation part 3001 of the dial member 300 extending outside the shell 10 is provided with an indicating protrusion 3001a, which is collinear with the central axis of the selection part 3002. When the indicating protrusion 3001a is located at the end position of the two ends of the sliding groove 100, it is in the tuning state (volume increase or decrease). When the indicating protrusion 3001a is located at the middle position of the sliding groove 100 (third position), it is in the non-tuning state. In this way, the user can also perform blind operation in a dark environment or a scene with poor light.
[0045] Embodiment 2
[0046] Figures 7-8 The specific structure of the second embodiment of the volume adjusting structure of the utility model is shown. As shown in Figures 7-8 The difference between this embodiment and embodiment 1 is that the volume adjusting structure of this embodiment further comprises an elastic reset member 40. The elastic reset member 40 is specifically a torsion spring. As shown in Figure 8 The elastic reset member 40 is composed of an elastic body 400 and elastic arms 402 connected to the opposite sides of the elastic body 400. The elastic body 400 of the elastic reset member 40 is fixed to the operation part 3001 of the dial member 300, and the two elastic arms 402 are fixed to the two limiting columns 102, thereby providing a restoring force for the dial member 300 through the elastic reset member 40. When the volume adjusting structure is in the non-tuning state, the selection part 3002 of the dial member 300 is located at the third position, and when the volume is to be increased, the dial member 300 is operated to make the selection part 3002 turn to the first position. When the volume is increased to the target volume, the hand can be released, and the selection part 3002 of the dial member 300 is automatically reset from the first position to the third position under the action of the elastic reset member 40. Similarly, when the dial member 300 is operated to make the selection part 3002 turn to the second position. When the volume is reduced to the target volume, the hand can be released, and the reset elastic member 40 drives the selection part 3002 to return to the third position from the second position. During the operation of the dial member 300, the elastic reset member 40 will be slightly deformed and provide a certain resistance feeling. In this way, by setting the elastic reset member 40, the selection part 3002 of the dial member 300 can be returned to the original position after the tuning is completed, and the feedback resistance feeling is provided for the user.
[0047] In addition, the utility model also provides a kind of wearable equipment, including the volume adjusting structure of any described above.In this embodiment, wearable equipment is specifically headphones, and the shell 10 is the earshell of headphones, and circuit board 20 and volume adjusting assembly 30 are all arranged in the earshell of headphones.
[0048] Relative to prior art, the volume adjusting structure of the utility model adopts mechanical dial wheel mode, rotates to different positions by operating dialing member relative to circuit board, to turn on the first circuit for controlling volume increase or the second circuit for controlling volume decrease, triggers the program of controlling volume increase and decrease, to realize the adjustment of volume.Based on this rotary contact structure design, user only needs to dial wheel to corresponding position by finger, to complete tuning operation.Compared with touch panel key, the dial wheel type volume adjusting structure of the utility model has tactile feedback, and is not easy to cause false triggering;Compared with traditional mechanical key, the dial wheel type tuning of the utility model can reduce noise generated by key.The volume adjusting structure of the utility model can be applied to wearable equipment, such as headphones, and has simple structure, strong practicability and good user experience.
