Embodiment Construction

[0018] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the specification and the drawings, elements that have the same function and structure are denoted with the same reference numerals, and repeated explanation of these structural elements is omitted.

[0019] figure 1 Shown is a schematic structural diagram of a single-stage antenna. The cross-sectional shape of the monopole antenna 1 can be arbitrary, but the preferred solution is circular. The single-stage antenna with a circular cross-section has better performance than antennas with other shapes, and is convenient for extended installation in the spectacle frame; secondly, the single-stage antenna designed by the invention is applicable to all wireless fields.

[0020] like figure 2 , image 3 As shown, the bluetooth 3D glasses include glasses legs 6, glasses frames 4, two liquid crystal glasses lenses 5, and a PCB board 2, and...

Abstract

The invention provides a pair of Bluetooth 3D (three-dimensional) spectacles which are provided with spectacle legs, a spectacle frame, two liquid crystal spectacle lenses and a PCB (Printed Circuit Board). The Bluetooth 3D spectacles also comprise a single-stage antenna. The single-stage antenna is arranged in the spectacle frame and extends out of the PCB. In the scheme, a space inside a right spectacle frame of the spectacles is efficiently utilized, the antenna capable of being placed inside the spectacles is designed, the area of the PCB is saved, the cost is reduced, and the integral ID (Inner Diameter) of the spectacles is small, thus being light and simple.

Description

technical field [0001] The invention relates to the technical field of bluetooth 3D glasses, in particular to the technical field of antenna devices for bluetooth 3D glasses. Background technique [0002] Due to the increasing functional requirements of the current 3D glasses, the space of the antenna in the 3D glasses is constantly shrinking. The size and position of the antenna must be within the range specified by the customer. At present, the blue 3D glasses generally use PCB printed antenna or CHIP antenna. Since the printed antenna occupies a large amount of PCB space, the cost of the CHIP antenna is relatively high, and the prohibited wiring area of ​​​​the PCB printed antenna or CHIP antenna will make the PCB board area large, affecting The overall ID size of the eye is changed. However, if the space occupied by the antenna is reduced, the transmission and reception of the antenna will be affected, and the performance of the antenna will drop directly. This will no...
