[0026] Reference Figure 1-6 The image shown is a preferred embodiment of the present invention.

[0027] A scroll wheel-controlled Bluetooth earphone case includes a case body 1, a scroll wheel 2, an encoder 3, a micro switch 4, and a control board 5. The control board 5 is assembled inside the case body 1. The encoder 3 and the micro switch 4 are arranged in a conductive manner with the control board 5. The two ends of the scroll wheel 2 form a rotating shaft 22 and a pressing shaft 23, respectively. The encoder 3 is embedded in the rotating shaft 22 and is used to detect the rotation state of the rotating shaft 22. The pressing shaft 23 is arranged correspondingly with the micro switch 4 and is used to receive the pressing force of the pressing shaft 23. The scroll wheel 2 is movably assembled and can be in a rolling or pressing state when subjected to external force.

[0028] The aforementioned scroll wheel-controlled Bluetooth earphone case allows users to control the earphones by applying rolling or pressing force to the scroll wheel 2. When the scroll wheel 2 receives the rolling or pressing force, it transmits signals to the encoder 3 and micro switch 4 via the rotation shaft 22 and pressing shaft 23. The encoder 3 and micro switch 4 then transmit signals to the control board 5, enabling earphone control. For example, the playback status and mode of the earphones can be controlled by adjusting the rotation angle, speed, direction, and pressing position of the scroll wheel 2. This simple and convenient operation enhances the user experience.

[0029] The scroll wheel controlled Bluetooth earphone case includes a case bracket 11, which is installed inside the case body 1, and a control board 5 is mounted on the case bracket 11. The case bracket 11 facilitates the setting of the control board 5 and enhances the stability of the setting of the control board 5.

[0030] The control board 5 has a preset control program that enables the reception and output of commands, as well as the control of the headphones, encoder 3, and micro switch 4.

[0031] The control board 5 has a remote transmission module for signal transmission, which can be a Bluetooth module; this enables signal transmission between the control board 5 and the headphones, thereby allowing control of the headphones.

[0032] The encoder 3 is used to acquire the rotation information of the rotating shaft 22 when it rotates and send it to the control board 5. When the control board 5 receives the rotation information, it generates the corresponding command and sends the command to the earphone.

[0033] Rotation information includes rotation angle, rotation speed, and rotation direction.

[0034] When the roller body 21 is pressed, it drives the pressing shaft 23 to move in the radial direction. The micro switch 4 is used to acquire the pressing information of the pressing shaft 23 when the pressing shaft 23 moves and send it to the control board 5. When the control board 5 receives the pressing information, it generates a corresponding instruction and sends the instruction to the earphone.

[0035] Press information may include press duration and number of presses.

[0036] For example, when scroll wheel 2 is scrolled, it outputs a volume adjustment command. When scroll wheel 2 is scrolled down, it causes the headphones to decrease or lower the audio or call volume based on the volume adjustment command; when scroll wheel 2 is scrolled up, it causes the headphones to increase or raise the audio or call volume based on the volume adjustment command.

[0037] For example, when the scroll wheel button 2 receives a pressing pressure, it outputs a playback status control command. For instance, when the scroll wheel button 2 is pressed briefly, the headphones switch between the playback and pause states, i.e., when in the playback state, it switches to the pause state, and when in the pause state, it switches to the playback state. When the scroll wheel button 2 is pressed for a long time, the headphones switch between different modes.

[0038] The rotating shaft 22 is arranged in a circular shape, which facilitates the encoder 3 to judge the rotation state of the rotating shaft 22 and to extract rotation information.

[0039] The pressing shaft 23 is arranged in a rectangular column shape and has four axial surfaces, one of which is arranged in parallel contact with the micro switch 4; this facilitates the cooperation between the pressing shaft 23 and the micro switch 4, and also facilitates the micro switch 4 to extract pressing information.

[0040] The box bracket 11 includes a rotating plate and a pressing plate, which are arranged at intervals. The rotating shaft 22 extends through the rotating plate and passes through the encoder 3, and the rotating shaft 22 is movably arranged. The pressing shaft 23 extends through the pressing plate and is arranged correspondingly to the micro switch 4, and the pressing shaft 23 is movably arranged.

[0041] In this way, the rotating plate and the pressing plate work together to position the rotating shaft 22 and the pressing shaft 23, thereby improving the stability of the roller key 2.

[0042] The roller key 2 includes a roller body 21, which is arranged in a cylindrical shape. Along the axial direction of the roller body 21, the two ends of the roller body 21 are respectively connected to the rotating shaft 22 and the pressing shaft 23. The roller body 21 is located between the rotating plate and the pressing plate. The outer periphery of the roller body 21 forms a rolling arc surface, which is used to receive rolling force.

[0043] Since the roller body 21 is cylindrical, it is easy for the roller body 21 to rotate. At the same time, the curved surface makes it easy for the user to touch and operate.

[0044] The box body 1 has a roller groove, which is arranged in a through manner and is connected to the outside. The roller body 21 is movably embedded in the roller groove, and the roller groove is used for the exposed roller surface. This makes the roller body 21 embedded, reducing the exposure of the roller body 21, protecting the roller body 21, and preventing accidental touch of the roller body 21.

[0045] The outer surface of the box body 1 has a recessed hole 15. The recessed hole 15 is arranged inward and is connected to the roller groove. The recessed hole 15 is arranged in an flared shape in the direction away from the roller groove. The roller body 21 extends to the recessed hole 15. Under the action of the recessed hole 15, the cross-section is enlarged, which makes it easier for the finger to enter, thereby making it easier for the user to control the roller body 21 to roll and press.

[0046] The control board 5 is vertically fixed, and the encoder 3 and micro switch 4 are stacked and fixed with the control board 5, with the encoder 3 and micro switch 4 arranged at opposite ends; this makes the layout of each component more compact and reduces space occupation.

[0047] The box support 11 includes multiple plate-fixed columns 12. The inner ends of the plate-fixed columns 12 are fixedly arranged, and the outer ends of the plate-fixed columns 12 are laterally extended. The plate-fixed columns 12 penetrate the control plate 5. Under the action of each plate-fixed column 12, the stability of the control plate 5 is enhanced, and the cooperation effect between the control plate 5 and the roller body 21 is also effectively guaranteed.

[0048] The box bracket 11 includes four plate fixing columns 12, which are arranged in a symmetrical manner at the four corners, so that the control plate 5 is fixed more evenly and the stability of the control plate 5 is enhanced.

[0049] The case support 11 includes four plate fastening posts 13, which are arranged at the four corners. The inner ends of the plate fastening posts 13 are fixed, and the outer ends of the plate fastening posts 13 form plate fastening heads 131, which are used to fasten the control plate 5. Under the action of each plate fastening post 13, a fastening force is applied to the control plate 5, which enhances the stability of the control plate 5, prevents the control plate 5 from shaking, facilitates the carrying of the earphone case, and also effectively ensures the cooperation effect between the control plate 5 and the roller body 21.

[0050] The control board 5 has a central slot, which is arranged in a through manner, and the roller key 2 passes through the central slot; this improves the cooperation between the control board 5 and the roller key 2, reduces the space occupied by each component, and facilitates the assembly of the roller key 2 and the control board 5.

[0051] The box bracket 11 includes four reinforcing columns 14, which are arranged at the four corners. The inner ends of the reinforcing columns 14 are fixed, and the outer ends of the reinforcing columns 14 penetrate the groove in the plate. The outer surface of the reinforcing columns 14 is in contact with the control plate 5. Under the action of each reinforcing column 14, a limiting force is applied to the control plate 5 to prevent the control plate 5 from shaking and to enhance the stability of the control plate 5.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
