Problems solved by technology

Additionally, in structures where the switch is not integral to the housing, mechanical switches can result in structures with outwardly protruding designs
Therefore, structures with mechanical switches may result in obtrusive designs and may require large internal spaces
[0006] In addition, if direct contact is made with an electrically connected mechanical switch, there may be a risk of electric shock, and due to structural defects of the mechanical switch, it may be difficult for the mechanical switch to be dustproof and waterproof

Abstract

A touch operation sensing device, a sensing coil and an electronic device are provided. The touch operation sensing device is applied to the electronic device. The electronic device includes a touch interaction switch integrally formed with a housing and including a conductive first touch member having a first insulated hole. The touch operation sensing device includes an oscillation circuit and a touch detection circuit. The oscillation circuit is configured to generate an oscillation signal having a variable resonance frequency based on a touch capacitance generated by an interaction with a touch body touching the first touch member, the first insulated hole, and the sensing coil. The touch detection circuit is configured to detect a touch interaction using the oscillation signal from the oscillation circuit.

Description

[0001] This application claims the benefit of priority from Korean Patent Application No. 10-2019-0172974 filed with the Korean Intellectual Property Office on December 23, 2019, the entire disclosure of which is incorporated by reference for all purposes here. technical field [0002] The following description relates to a touch operation sensing device, a sensing coil and an electronic device. Background technique [0003] In general, thinner, simpler and cleaner form factors are preferred for wearable devices. To this extent, typical mechanical switches are rarely implemented in wearable devices. Dustproof and waterproof technology is currently being implemented, thus resulting in models with smooth and uniform form elements. [0004] Currently, technologies such as a touch-on-metal (ToM) technology that senses a touch on metal, a capacitive sensing technology using a touch panel, a micro-electro-mechanical system (MEMS) technology, a force-touch function, and a micro-s...
