Electronic Devices and Wearable Electronic Devices

Abstract

The present invention provides an electronic device and a wearable electronic device, which can ensure antenna performance in a limited space. The wearable electronic device includes: a housing, a wearing part, a circuit board and a metal extension unit; the wearing part is coupled to the shell body; the circuit board is disposed in the casing, the circuit board has a grounding area and an antenna, and the antenna is disposed on a first side of the circuit board; the metal extension unit is disposed outside the casing, and the metal extension unit is coupled to The grounding area meanders back and forth along the second side of the circuit board.

Description

technical field [0001] The present invention relates to a wearable electronic device, in particular to a wearable electronic device that uses a grounding area of ​​a circuit board to externally connect a metal unit to increase antenna performance. Background technique [0002] The implementation of wearable electronic devices, such as wrist watches or heart rate monitors, needs to be worn for a long time. In order to allow users to have a good experience and not feel uncomfortable due to weight, thin and short are important design criteria, but for adding communication Functional electronic devices, in a limited space, make the antenna receive well and maintain a stable communication function, which is a major challenge for antenna designers. [0003] In order to improve the receiving performance of the antenna, as in the prior art U.S. Patent No. 7,778,118, the ceramic antenna is installed in the housing. Although the ceramic antenna has better receiving capability, the siz...

[0002] The implementation of wearable electronic devices, such as wrist watches or heart rate monitors, needs to be worn for a long time. In order to allow users to have a good experience and not feel uncomfortable due to weight, thin and short are important design criteria, but for adding communication Functional electronic devices, in a limited space, make the reception of the antenna good and maintain a stable communication function, which is a major challenge for antenna designers

[0003] In order to improve the receiving performance of the antenna, as in the prior art U.S. Patent No. 7,778,118, the ceramic antenna is installed in the housing. Although the ceramic antenna has better receiving capability, the size of the outer housing needs to be increased, which is not conducive to the design criteria of light, thin and short wearable electronic devices; One method is as in the prior art U.S. Patent No. 8,275,327. The antenna is arranged on a metal shell and coupled to the circuit board with a feeder. Although this method can effectively reduce the volume and maintain the antenna performance, it has a relatively complicated structure and high cost
