The author provides a button mechanism, especially a button mechanism with a radio function.

The portable electronic device usually has an input interface such as a keyboard, a mouse, a touchpad, and a radio. In related products of touch computers, such as tablet computers, only the touchpad and the radio are usually used as their signal input interfaces. A conventional tablet computer has a microphone disposed on a side or a front surface of a casing. If the sound receiver is placed on the side of the casing, because the sound transmission hole and the direction of transmission of the sound signal emitted by the user are perpendicular to each other, the sound collection effect is not good; if the sound receiver is to be placed on the front surface of the casing, The sound hole is drilled in the glass of the touch panel, so that the sound receiver can face the user, but the manufacturing cost is correspondingly improved, and the glass drilling is a destructive process. If the drilling quality is not good, the whole glass must be scrapped. Therefore, traditional tablet PCs have the disadvantages of low yield and high material cost.

This creation provides a button mechanism with a radio function to solve the above problems.

The patent application scope of the present invention discloses a button mechanism having a sound receiving function, which comprises a base, a sound pickup unit, a lifting support member and a pressing member. The radio unit is set on the base. The lifting support is disposed on the base and suspended above the sound receiving unit. The pressing member is disposed on the lifting support to move relative to the base. The pressing member has a hole, and the hole is directed to the sound pickup unit.

The creation integrates the radio unit into the configuration of the button mechanism, and the single button mechanism has both the button and the microphone function, which can save the internal space of the housing of the electronic device, and can also reduce the processing and assembly cost of the product.

Please refer to FIG. 2 to FIG. 5 , FIG. 2 is a group diagram of the button mechanism 16 of the first embodiment of the present invention, and FIG. 3 is an exploded view of the components of the button mechanism 16 of the first embodiment. FIG. Fig. 5 is a cross-sectional view showing the key mechanism 16 of the first embodiment of the present invention in different operational states, respectively. The button mechanism 16 includes a base 18, a sound pickup unit 20, a lifting support member 22, a pressing member 24, an actuating member 26, and a limiting member 28. The pedestal 18 can be a support base plate or an internal circuit board of the electronic device 10. The sound pickup unit 20 is disposed on the base 18. The lifting support 22 is disposed on the base 18 and suspended from the sound pickup unit 20 Above. The pressing member 24 is disposed on the lifting support 22 to move up and down relative to the base 18 by the lifting support 22.

In addition, the actuating member 26 extends over the pressing member 24 for triggering the electronic switch of the base 18. The limiting member 28 is disposed on the base 18, and the limiting member 28 is a covering structure, and the receiving unit 20 and the lifting support member 22 are received in the limiting member 28 to provide protection. In addition, since the user activates the button mechanism 16 by touching the pressing member 24, the pressing member 24 has a partial structure exposed to the limiting member 28, and the pressing member 24 is coupled to the limiting member 28 in a relatively movable manner, according to the pressing. The amount of movement of the member 24 is the pressing stroke of the button mechanism 16.

In the first embodiment, the lifting support 22 may be an elastomer, such as a rubber material, or a variety of materials having elastic compression/elastic recovery characteristics. The top end 221 of the lifting support 22 (elastomer) has an opening 30, and the bottom end 223 of the lifting support 22 (elastic body) has an accommodating space 32, and the accommodating space 32 communicates with the opening 30. The sound unit 20 is located in the accommodating space 32. When the pressing member 24 is combined with the lifting support member 22, the opening 30 of the lifting support member 22 communicates with the breaking hole 34 of the pressing member 24, so that the broken hole 34 is directed to the sound pickup unit 20. The external sound signal can enter the interior of the lifting support 22 through the pressing member 24 through the combination of the breaking hole 34 and the opening 30, and improve the sound receiving performance of the sound pickup unit 20 by utilizing the rubber material property of the elastic body.

Actuator 26 includes a first section 36 and a second section 38. One end of the first section 36 is disposed on the bottom surface of the pressing member 24, and the second section 38 is bently coupled to the other end of the first section 36, that is, the actuator 26 may be of an L-shaped configuration. Furthermore, the second section 38 can have a conductive sheet 40 on the surface 381 facing the susceptor 18 for conducting the first electrode 42 and the second electrode 44 on the pedestal 18 (such as the aforementioned electronic switch). In particular, the present invention may be applied with a conductive coating or a conductive film on the surface 381 instead of the conductive sheet 40, or the entire structure of the second portion 38 may be made of a conductive material instead of the conductive sheet 40. The embodiment of the conductive sheet may not be limited to the above description, and the end view design requirements set.

The pressing member 24 is moved closer to or away from the base 18 by the lifting support 22 to move between the first position shown in FIG. 4 and the second position shown in FIG. As shown in FIG. 4, the external force is applied to the pressing member 24 to cause the lifting support member 22 to be compressed and deformed, and the pressing member 24 is moved downward relative to the base 18 (or the limiting member 28), and the conductive sheet 40 of the pressing member 24 can be simultaneously contacted. The first electrode 42 and the second electrode 44 of the susceptor 18 turn on the electronic switch. As shown in FIG. 5, after the external force is removed, the elastic restoring force of the lifting support 22 drives the pressing member 24 to move up relative to the base 18 (or the limiting member 28) until the second section 38 of the actuating member 26 abuts. The stop portion 46 of the limiting member 28 stops moving; at this time, the conductive sheet 40 separates the first electrode 42 and the second electrode 44 to close the electronic switch.

In the first embodiment of the present invention, regardless of whether the pressing member 24 is moved to the first position or the second position, the breaking hole 34 of the pressing member 24 is always coupled to the opening 30 of the lifting support member 22, and the broken hole 34 is directed to the electronic device. The front side (upper surface) of the device 10. In this way, during the operation of the electronic device 10, the transmission direction of the sound signal emitted by the user is substantially parallel to the structural penetration direction of the sound receiving hole (opening 30) of the button mechanism 16, which not only saves the electronic device 10 and the button mechanism. The internal space configuration of 16 can also effectively improve the sound collection effect of the sound pickup unit 20.

The number of actuators 26 of the present creation may be one or more. The button mechanism 16 can accurately turn on the first electrode 42 and the second electrode 44 by using an actuating member 26, and the design of the stopping portion 46 prevents the pressing member 24 from being separated from the limiting member 28. However, the button mechanism 16 preferably also uses a plurality of actuators 26 that are discretely disposed at different locations of the pusher 24. A plurality of actuating members 26 can be wrapped around the lifting support 22, and each actuating member 26 is slidably contacted with the sliding surface 48 of the lifting support member 22, respectively. When the pressing member 24 drives the lifting support member 22 (elastic body) to be elastically deformed, the plurality of actuating members 26 abut against the sliding surface 48 of the lifting support member 22, thereby preventing the pressing member 24 from being tilted during pressing, providing Better user experience.

Please refer to Fig. 6, which is a cross-sectional view showing the structure of the button mechanism 16' according to the second embodiment of the present invention. Compared with the first embodiment, the elevating support member 22' of the second embodiment is a scissor-foot structure, and the remaining components having the same reference numerals as those of the first embodiment have the same structure and function, and thus the description is not repeated. The lifting support 22' includes a first support member 50 and a second support member 52 that are pivotally connected to each other. The upper and lower ends of the first support member 50 and the second support member 52 are respectively pivotally connected to the pressing member 24 and the base 18. The sound unit 20 is located between the first support member 50 and the second support member 52, and the hole 34 of the pressing member 24 faces the sound receiving unit 20. Therefore, the button mechanism 16' of the second embodiment can provide excellent sound receiving performance. .

In summary, the present invention designs the lifting support of the button mechanism into a hollow structure, and the charging unit can be accommodated in the lifting support regardless of whether the lifting support is an elastic body or a scissor foot structure. The creation further forms a hole in the pressing member, and the hole is aligned with the sound receiving unit in the lifting support; the actuating member surrounds the periphery of the lifting support member, and contacts or moves away from the base first with the moving member. Second electrode. The creation integrates the radio unit into the configuration of the button mechanism, and the single button mechanism has both the button and the microphone function, which can save the internal space of the housing of the electronic device, and can also reduce the processing and assembly cost of the product.
