Description

Technical Field

[0001] The utility model belongs to the technical field of earphone key components, and specifically designs an earphone with keys having rotating and pressing functions. Background Art

[0002] Existing headphones on the market are equipped with buttons to adjust the volume or turn the machine on and off. In order to simplify the button structure, some headphones only have one button to achieve the functions of volume adjustment and power on and off. For example, the applicant has applied for a utility model patent with application number 202321046179.5. The expansion button can be pressed to move, thereby expanding the button position by pressing the protrusion, and can also be rotated, thereby driving the protrusion to rotate and cooperate with the angular displacement encoder.

[0003] In the actual manufacturing process, in order to facilitate processing and assembly, the above-mentioned expansion button and protrusion are an integrated structure. However, this requires that the protrusion and the expansion button position have a high degree of concentricity. Otherwise, the protrusion will bend after assembly, and there will be a jamming problem during the rotation of the expansion button. In addition, the protrusion cannot be pressed accurately to the expansion button position, or even cannot press the expansion button position. Utility Model Content

[0027] In the present invention, unless otherwise clearly defined and specified, the terms "installation", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Furthermore, those skilled in the art may combine and associate different embodiments or examples and features of different embodiments or examples described in this specification without mutual contradiction.

[0029] The following is combined with Figure 1-3 The technical solution of the utility model is further explained.

[0030] A headset with a button that can be rotated and pressed, see Figure 1-3 , including having an opening (such as Figure 2The housing 1 (opening to the left) is shown, and includes a driven member 2, a reset member 3, a rotating shaft 4 and a rotating shaft support member 5 for supporting the rotating shaft 4. A circuit board 6 is provided in the housing 1. The circuit board 6 is provided with an expansion key position 61 facing the opening side. The driven member 2 is movably connected to the opening and is driven to rotate or move toward the expansion key position 61. The reset member 3 is used to drive the driven member 2 to move away from the expansion key position 61. A plug-in slot is provided on the side of the driven member 2 close to the expansion key position 61. The rotating shaft 4 includes a plug-in end 41 and a pressing end 42, the plug-in end 41 is plugged into the plug-in slot, the cross-sectional size of the plug-in slot is larger than the cross-sectional size of the plug-in end 41, and the side walls of the two are limited to cooperate so as to drive the rotating shaft 4 to rotate when the actuated member 2 rotates, and the pressing end 42 is used to press the extended key position 61 when the actuated member 2 moves toward the side of the extended key position 61, and the projection of the extended key position 61 in the axial direction of the rotating shaft 4 overlaps with the plug-in slot to ensure that the rotating shaft 4 can press the extended key position 61 when it is driven after being assembled. Preferably, the projection of the extended key position 61 in the axial direction of the rotating shaft 4 completely overlaps with the plug-in slot, which ensures that the pressing end 42 of the rotating shaft 4 can completely press the extended key position 61 when it is driven, thereby improving the reliability of the key. More preferably, the center of the extended key position 61 is coaxial with the center of the plug-in slot, which further improves the transmission effect between the rotating shaft 4 and the extended key.

[0031] The cross-sectional dimensions of the above earphones are larger than the cross-sectional dimensions of the plug-in end 41. The plug-in slot has sufficient assembly space so that the shaft 4 has a certain degree of mobility in the radial direction of the plug-in slot. When the relative position between the plug-in slot and the expansion key position 61 deviates (the deviation may be caused by the assembly or manufacturing process), the shaft 4 can adjust its position to ensure the concentricity between the plug-in slot and the expansion key position 61. This can not only ensure that the rotation can accurately press the expansion key position 61, but also improve the transmission effect between the driven part 2, the shaft 4 and the expansion key position 61, and avoid the problem of jamming. The shaft 4 is connected to the driven part 2 by plugging it into the plug-in end 41, which is convenient to assemble. Under the action of the shaft support 5, its assembly stability is further improved.

[0032] Among them, the active member 2 is movably connected, specifically, it is slidably connected to the shell 1 and can rotate relative to the shell 1. As for the specific structural setting, it can be set according to needs. For example, a slide groove 13 is provided in the shell 1, and the end of the active member 2 entering the shell 1 is clamped on the slide groove 13 through a retaining spring 21. Thus, the active member 2 is connected to the shell 1, and it can move along the direction of the slot and can also rotate.

[0033] For easy assembly, the housing 1 may be configured as an upper cover 11 and a lower shell 12 that are detachably connected.

[0034] In this embodiment, see Figure 2-3The cross-sectional shape of the plug slot is polygonal, and the cross-sectional shape of the plug end 41 is the same as the plug slot. Preferably, the cross-sectional shapes of both are quadrilaterals. When the plug end 41 is inserted into the plug slot, there is an assembly gap between the side wall of the plug end 41 and the inner side wall of the plug slot, which ensures that the shaft 4 can adjust its concentricity with the plug slot and the expansion key position 61. In addition, the gap between the plug end 41 and the plug slot should ensure that the shaft 4 can be driven to rotate when the driven member 2 rotates. The specific size of the gap can be set according to actual needs.

[0035] In this embodiment, see Figure 3 The side wall of the plug-in end 41 is tilted toward the center position away from the expansion key position 61, which makes it easier for the rotating shaft 4 to be inserted into the plug-in slot and improves assembly efficiency.

[0036] In this embodiment, see Figure 2-3 The shaft support 5 is provided with through holes 51 passing through both ends, and the through holes 51 are arranged along the axial direction of the shaft 4. The pressing end 42 passes through the through holes 51 and then cooperates with the expansion key position 61. The shaft 4 is supported by providing the through holes 51 on the shaft support 5, which is conducive to improving the concentricity of the shaft 4 and the plug-in slot and the expansion key position 61, and also limits the shaft 4, thereby improving its assembly stability and reliability. Preferably, the shaft 4 fixing member is an angular displacement encoder for measuring the rotation angle of the driven member 2.

[0037] In this embodiment, the reset member 3 is a spring, which is sleeved on the rotating shaft 4, with one end of the spring being pressed against the driven member 2 and the other end being pressed against the fixing member of the rotating shaft 4.

[0038] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
