Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

With the rapid development of mobile communication technology, people's life is becoming more and more intelligent, and wearable electronic devices such as smart watches are becoming a current research hotspot. The intelligent watch is wearable intelligent equipment which is upgraded by the traditional intelligent communication equipment through light weight and wearable, and can realize the functions of target positioning, video playing, telephone chatting, surfing the internet and the like. As can be seen from the above, the smart watch needs to have a wireless communication function. The antenna is an important component of the device and the performance will directly impact the user experience. However, the clearance area inside the current smart watch is smaller, the effective utilization area is reduced, and the antenna performance is deteriorated.

In order to solve the problem of deterioration of antenna performance caused by the reduction of the effective utilization area, the following two technical solutions have been proposed in the related art.

One of them, the antenna, is designed on the back of the dial or on the bezel. For this technical scheme, the structure of dial plate is comparatively compact, and the antenna headroom area is less, and effective area reduces, so no matter be the antenna design in dial plate inside or outside, less antenna headroom area can all cause antenna performance to deteriorate.

And the second antenna is designed on the watchband. With this technical solution, since the wristband is in direct contact with the human body, the influence on the performance of the antenna is great, and the wristband cannot be replaced at will in order to ensure a wireless communication function.

The above, the scheme or the defect in the related art.

The display 50 may be a liquid crystal display 50 (Liquid Crystal Display, LCD) or an Organic Light-emitting diode display 50 (Organic Light-EmittingDiode, OLED), among others.

The housing 10 may be a metallic or non-metallic material, such as stainless steel, aluminum alloy, titanium alloy, plastic, rubber, ceramic or wood material, or the like. The material of the housing 10 may be set according to actual needs. The housing 10 has an accommodation space that can accommodate structures such as the battery 60, the circuit board 70, and the like described above.

The housing 10 is symmetrically provided with a first groove 11 and a second groove 12 for respectively placing the first metal connector 20 and the second metal connector 30.
