Referring to FIG. 4 to FIG. 6 , the pressing unit 3 moves upward until the second abutment surface 315 of the outer expansion part 312 abuts against the first abutment surface 112 of the inner sleeve 11 and is limited, for the The highest point where the pressing unit 3 moves upward relative to the housing unit 1 (as shown in FIG. 5 ). At this time, a maximum distance D is formed between the first limiting surface 121 and the second limiting surface 321 . When the pressing unit 3 moves down until the second limiting surface 321 of the pressing member 32 abuts against the first limiting surface 121 of the outer sleeve 12 , the pressing unit 3 is positioned relative to the housing unit 1 . Move down to the lowest point (as shown in Figure 6).

The elastic pressing unit 4 includes a pressing piece 41 which is in the shape of a protrusion and leans against the button 22 , and an elastic force that elastically resists the top side of the pressing piece 41 and the limiting groove surface 316 of the rotating shaft 31 .

The top side of the elastic pressing member 42 is located in the limiting groove 317 , and can use elastic force to pass through the pressing member 41 to press the key 22 when deformed downward under force, and accumulate elastic force to reset the key 22 . In this embodiment, the elastic pressing member 42 is a compression spring, and is in a state of elastic pressing. The elastic pressing member 42 has a maximum compression amount, and the maximum compression amount is greater than the maximum distance between the first limiting surface 121 and the second limiting surface 321 .

The elastic force adjustment unit 5 includes an internal thread 511 and is screwed on The adjusting member 51 of the external thread 314 of the bottom shaft portion 313 and an elastic adjustment member 52 . The shifting member 51 is in the shape of a ring sheet, and has a second abutting surface 512 facing downwards, and anti-rotation outer surfaces 513 located on opposite sides of the left and right sides. The anti-rotation outer surfaces 513 can move up and down along the anti-rotation inner surfaces 113 of the inner sleeve 11 respectively, and cooperate with the design that the inner thread 511 is screwed to the rotating shaft member 31, so that the transfer member 51 It can move up and down along the longitudinal direction T without turning when the rotating shaft member 31 is turned. The elastic adjusting member 52 elastically abuts between the first abutting surface 111 and the second abutting surface 512 , and has an elasticity to drive the pressing unit 3 to move away from the first abutting surface 111 . force.

The method of adjusting the pressing force of the adjustable switch device 10 can be based on the force that the user wants to apply, and the pressing member 32 can be rotated to synchronously drive the rotating shaft member 31 to rotate, so that the shifting member 51 can move along the longitudinal direction T Move to a predetermined position, and then pre-compress a predetermined deformation amount of the elastic force adjusting member 52 .

When the pressing unit 3 is not pressed, the pressing member 32 is pushed up by the elastic pressing unit 4 until the second abutting surface 315 of the rotating shaft member 31 abuts against the first abutting surface 315 of the inner sleeve 11 . The abutting surface 112 is at the highest point, and the switch unit 2 is in the second state.

Referring to FIG. 1 , FIG. 5 and FIG. 6 , when the user intends to operate the effector, the pressing member 32 is pressed down with force. During the downward movement of the pressing member 32 , the limiting groove surface 316 is used to press against the elastic pressing member 42 , and the second abutting surface 512 is used to press against the elastic force adjusting member 52 simultaneously. When the elastic force pressing unit 4 presses the elastic force of the button 22 When the force is greater than the minimum touch force of the button 22, the switch element is switched to the first state, and the effector is activated to modulate the output audio for specific sound effect processing.

Due to the applied force of pressing down the pressing unit 3 , at least the shifting member 51 elastically compresses the elastic adjusting member 52 , and the limiting groove surface 316 elastically compresses the elastic member pressing member 41 . Then, the button 22 is pressed through the pressing member 41 through the elastic force of the pressing member 41 . Therefore, the applied force for pressing down the pressing unit 3 needs to be no less than the sum of the elastic force of the elastic pressing member 42 capable of pressing the button 22 and the elastic force of the elastic adjusting member 52 simultaneously compressed.

After use, the user no longer presses down on the pressing member 32, and the pressing member 32 is pushed up and reset by the elastic force of the elastic pressing member 42 and the elastic force of the elastic adjusting member 52, and the button 22 is no longer pressed. Pressed by the elastic pressing unit 4 to switch back to the second state.

In other variations of this embodiment, the first and second states can also be interchanged: when the button 22 is pressed by the elastic pressing unit 4, it is in the second state; when the button 22 is not pressed, it is in the second state. The bit is in the first state, depending on actual usage requirements.

Referring to Fig. 1, Fig. 7 and Fig. 8, when wanting to increase the applied force value of pressing down the pressing unit 3 required to press the button 22, so as to bring a relatively heavy feel, the pressing part 32 can be rotated to drive the adjusting unit 3. The moving part 51 moves down to increase the pre-compression degree of the elastic adjustment part 52 .

Since the elastic force adjustment member 52 is pre-compressed to a relatively large degree, the pressing down The unit 3 moves down until the displacement of the button 22 remains unchanged. Therefore, when the pressing unit 3 is pressed down, the amount of elastic deformation of the elastic force adjusting member 52 is relatively large. Moreover, according to the law of elasticity that the elastic force is proportional to the amount of elastic deformation, the elastic force that the user needs to overcome to compress the elastic adjustment member 52 is relatively large. Therefore, the applied force required to press down the pressing unit 3 to press the key 22 with the elastic pressing unit 4 is also relatively large.

Referring to Fig. 5 to Fig. 8, for a more specific description, refer to Table 1, which shows the deformation of the elastic force adjusting member 52 when the shifting member 51 shown in Fig. 6 and Fig. 8 is respectively positioned above and below for the adjustable switch device 10 amount, the elastic force of the elastic adjustment part 52, the deformation amount of the elastic pressing part 42, the elastic force of the elastic pressing part 42, and the minimum applied force value corresponding to the pressing unit 3 being pressed down and moving to the lowest point.

Assume that the coefficient of elasticity of the elastic adjustment member 52 is Kj, the coefficient of elasticity of the elastic force pressing member 42 is Kp, the distance between the transfer member 51 in Figure 6 and Figure 8 is X, and the displacement of the pressing unit 3 is ΔX, which is ignored The extremely small downward movement distance that the key 22 is pressed.

It should be noted that it is necessary to ensure that the elastic pressing member 42 and the elastic adjusting member 52 are in a state of elastic compression, so as to comply with Hooke's law that "when a force is applied, the stress of the material is proportional to the amount of deformation". Therefore, assuming that the adjustable switch device 10 is not pressed, the deformation amount of the elastic pressing member 42 is Y1, and the deformation amount of the upper elastic adjustment member 52 shown in FIG. 6 is Y2.

It can be seen from Table 1 that the adjustable switch device 10 can press down the required force value of the pressing unit 3 under the condition that the elastic force of the elastic pressing member 42 is constant when the button 22 is pressed, and can It changes with the degree of pre-compression of the transfer member 51 .

Specifically, the farther the distance between the shifting member 51 and the first abutting surface 111 is, the lower the preloading degree of the elastic adjustment member 52 is, and the smaller the force value required to press down the pressing unit 3 is; The closer the distance between the shifting member 51 and the first abutting surface 111 is, the higher the preloading degree of the elastic adjustment member 52 is, the greater the force value required to press down the pressing unit 3 is, and The required applied force is directly proportional to the deformation of the elastic adjustment member 52 .

In particular, since the elastic adjustment member 52 elastically abuts against the first abutting surface 111 of the outer sleeve 12 and the second abutting surface 512 of the adjusting member 51, the force of the elastic pressing unit 4 can be dispersed, Effectively prevent the elastic pressing unit 4 and the shell unit 1 from bearing all the downward pressure.

In addition, because the adjustable switch device 10 utilizes the elastic force of the elastic pressing unit 4 to press the key 22 instead of the user directly applying force to press, the effect of buffering the pressing force can be achieved. In this way, the button 22 will not be subjected to an excessive amount of pressing force, which effectively improves the service life of the switch element.

On the other hand, since the maximum distance D between the first limiting surface 121 and the second limiting surface 321 is smaller than the maximum elastic compression of the elastic pressing member 42 . Therefore, when the pressing unit 3 is pressed down to the lowest point, the elastic pressing member 42 can still be elastically compressed, so as to ensure that the elastic pressing unit 4 can buffer the user's pressing force.

To sum up, the adjustable switch device 10 of the present invention can adjust the preload degree of the elastic adjusting member 52 by adjusting the position of the adjusting member 51 by utilizing the design of the elastic adjusting unit 5 and the housing unit 1 . In this way, it is possible to adjust the time to use when pressing the button 22 The applied force value required by the user: the higher the preloading degree of the elastic adjustment member 52 is, the greater the applied force value required by the user. Also because the applied force value of pressing down the pressing unit 3 can be adjusted, the adjustable switch device 10 can be adjusted to conform to the pressing force used by different users, so that the user can adjust to a suitable pressing feeling; The predetermined specification of the switch unit 2 is not limited to the hand pressing unit 3 and the pedal pressing unit 3 . In addition, the elastic force adjustment unit 5 is elastically resisted between the pressing unit 3 and the housing unit 1, so as to prevent the elastic pressing unit 4 from being excessively stressed and reduce the service life of the device. On the other hand, the design of the elastic pressing unit 4 can buffer the force of pressing the button 22, further avoiding the reduction of the service life of the switch unit 2, so the purpose of the present invention can indeed be achieved.

But what is described above is only an embodiment of the present invention, and should not limit the scope of the present invention. All simple equivalent changes and modifications made according to the patent scope of the present invention and the content of the patent specification are still within the scope of the present invention. Within the scope covered by the patent of the present invention.
