Key structure and input device

Abstract

The invention relates to a key structure and an input device. The key structure comprises a key cap layer, a circuit layer, a touch generator, a support structure layer and an adhesion layer, wherein the key cap layer comprises a key cap region and a peripheral region; the peripheral region is adjacent to the key cap region; the circuit layer is arranged below the key cap layer; the touch generator is electrically connected with the circuit layer; the support structure layer is arranged below the circuit layer, and comprises an accommodating space; the touch generator is located in the accommodating space; and the adhesive layer is arranged between the key cap layer and the circuit layer and corresponds to the peripheral region. According to the key structure and the input device provided by the invention, the adhesive layer is only arranged on the part (namely the peripheral region) outside the key cap region, so that the kinetic energy loss when the touch generator vibrates can be effectively reduced. Furthermore, according to the key structure and the input device provided by the invention, the vibration effect can be strengthened, the appearance design can be reinforced, the operation convenience can be improved or the cost can be reduced through the key cap layer with different structure designs and different material choices.

Description

technical field [0001] The present invention relates to a key structure, specifically, the present invention relates to a key structure that reduces energy loss of tactile feedback and an input device having the key structure. Background technique [0002] With the increasingly high requirements for the thinning of electronic devices, the height of the applicable key structure is significantly reduced. Therefore, the conventional mechanical key structure with a large pressing stroke has been gradually replaced by small stroke keys or tactile keys. However, with the narrowing of the stroke or the use of touch input, it is difficult for the user to feel the feedback of pressing, so that the user cannot confirm whether the pressing operation is completed, causing troubles in operation. [0003] At present, there is a design that uses a vibrator to generate vibrations to provide feedback to the user, but this design usually adds a vibrator to the existing button structure, or t...

Problems solved by technology

However, such devices that provide vibration feedback usually vibrate the entire device together, or vibrate a certain surface of the device, which cannot provide independent and local feedback, which is not only not conducive to operation confirmation, but also generates high energy when vibrating wear and tear
