  • Patent number: 11953350
    Abstract: A capacitance detection apparatus and an electronic device are disclosed. The capacitance detection apparatus includes: a sensing module, a connecting circuit, and a differential detection circuit for detecting changes in capacitance of the sensing module; the sensing module comprises: a substrate, and a first sensing layer and a second sensing layer respectively located on two sides of the substrate; a first sensing unit of the first sensing layer is opposite to a second sensing unit of the second sensing layer, and the first sensing unit covers the second sensing unit; the first sensing unit and the second sensing unit are electrically connected to the differential detection circuit. When a detection object approaches the capacitance detection apparatus, the capacitance of the first sensing unit is influenced by the temperature and the detection object, and the capacitance of the second sensing unit is only influenced by the temperature.

  • Publication number: 20220077854
    Abstract: An approaching detection apparatus and an electronic device are provided. The apparatus for use in the electronic device includes: a first electrode, a second electrode, and a detection module configured to detect a variation of a mutual capacitance value between the first electrode and the second electrode. The variation of the mutual capacitance value is used to determine an approaching state of the electronic device. When a human body approaches the electronic device, the variation of the mutual capacitance value is a first variation. When a non-human body approaches the electronic device, the variation of the mutual capacitance value is a second variation. One of the first variation and the second variation is a positive value and the other thereof is a negative value.

  • Patent number: 11153672
    Abstract: A method for transmitting information, a communication device, a portable device and a communication system are provided. The method is applied to a portable device; and the method includes: receiving and/or transmitting information in an electric field coupling manner through a first coupling electrode disposed at the portable device and a second coupling electrode at an opposite end. In an embodiment of the present application, the information is received and/or transmitted through an electric field coupling manner, which could not only improve communication quality and connection reliability on the basis of reducing communication power consumption of a portable device (such as an earphone or a charging case), but also reduce a volume of the portable device, simplify a structure and further improve user experience.
