Abstract

The invention discloses a flash lamp device with an antenna function. The flash lamp device comprises a front shell, a motherboard and a lamp band arranged on the front shell at the same time, and a flash lamp arranged on the outer layer of the lamp band, the lamp band comprises a wiring layer and a conducting layer, which are insulated from each other, the wiring layer is electrically connected with the flash lamp, and the wiring layer is conducted with the motherboard; and an antenna feedback point and a grounding point are arranged on the motherboard, and the antenna feedback point and thegrounding point are electrically connected to different positions of the conducting layer. The invention discloses the flash lamp device with antenna function, and a mobile terminal. The conducting layer serving as an antenna is arranged on the lamp band of the flash lamp device, so that the flash lamp device achieves the antenna function while achieving a flicking effect, and in addition, it is beneficial for the ultrathin design of the mobile terminal.

Description

technical field [0001] The present invention relates to the technical field of antennas, and more specifically, to a flashlight device and a mobile terminal with an antenna function. Background technique [0002] In order to allow the touch screen to flash in certain scenarios, such as playing music or when there is a message notification, we can add a flash under the glass cover of the touch screen. The flashlight can be placed outside the area of ​​the LCD display on the lower part of the mobile phone. When the flashlight emits light, the glass cover of the touch screen will guide the light into the entire touch screen. For a better flash effect, the flash cannot be mounted on the small board, but the flash needs to be mounted on the light strip, which is assembled inside the phone and as close to the touch screen glass as possible. But because the light strip of the flashlight overlaps with the antenna area, the circuit and light strip of the flashlight will have a serio...
