Embodiment 1

[0096] In Embodiment 1, any one of the third connecting parts 27 may include: a connecting part extending from one or more positions on the second connecting part 26 close to the bottom end of the ear handle part 12 to a direction close to the top end of the ear handle part 12 , making full use of the space of the ear handle part 12 and realizing the compact layout of the Bluetooth earphone 100 .

[0097]Among them, the present application defines the shape of the third connecting portion 27, the number of the third connecting portion 27, the connecting position between the third connecting portion 27 and the second connecting portion 26, and the distance between the third connecting portion 27 and the second connecting portion 26. The included angle is not limited, as long as the total length of the second connection part 26 and the third connection part 27 is greater than 1 / 4 of the aforementioned wavelength and the current on the antenna radiator 23 is not opposite to the pa...

Embodiment 2

[0121] In the second embodiment, if Figure 17a and Figure 17b As shown, optionally, any third connecting portion 27 may include: extending from one or more positions on the second connecting portion 26 close to the bottom end of the ear handle portion 12 to a direction close to the bottom end of the ear handle portion 12 and The curved connection part makes full use of the space at the bottom of the ear handle part 12 and realizes the compact layout of the Bluetooth headset 100 . Moreover, the parasitic current on the third connecting portion 27 flows from the connection with the second connecting portion 26 along the body of the third connecting portion 27 to the end of the third connecting portion 27, so that the third connecting portion 27 becomes an antenna radiation. The parasitic of the body 23 enhances the performance of the antenna radiator 23.

[0122] Wherein, the present application does not limit the degree of bending deformation of the third connecting portion...

Embodiment 3

[0125] In the third embodiment, as Figure 18 As shown, optionally, any third connecting part 27 may include: the metal outer wall of the battery 29, and the metal outer wall of the battery 29 is connected to at least one position on the second connecting part 26 close to the bottom end of the ear handle part 12 The connection part makes full use of the occupied space of the battery 29 , saves the space of the ear handle part 12 , and realizes the compact layout of the Bluetooth headset 100 .

[0126] Wherein, the present application does not limit the thickness, material and area of ​​the metal outer wall. For example, the metal outer wall can be made of copper foil. For illustrative purposes, Figure 18 In the illustration, the third connecting portion 27 is the entire metal outer wall of the battery 29 as an example.

[0127] It should be noted, Figure 18 In the above, the oblique lines in the second connecting portion 26 and the antenna radiator 23 are not the corresp...

Abstract

The invention provides a Bluetooth earphone. The Bluetooth earphone comprises an antenna radiator, a first connecting part, a second connecting part and a third connecting part. The length of the antenna radiator and the length of the first connecting part are both 1 / 4 of the wavelength corresponding to one working frequency band of the antenna radiator, current on the antenna radiator flows to the bottom end of the ear handle part from the feeding point, current on the second connecting part flows to the grounding point from the bottom end of the ear handle part, the feeding point is locatedat the top end of the ear handle part, and the grounding point is a preset distance away from the feeding point. The total length of the second connecting part and the third connecting part is greaterthan 1 / 4 of the wavelength, the third connecting part is connected with the second connecting part, parasitic current on the third connecting part flows to the end part of the third connecting part from the joint of the third connecting part and the second connecting part, the current on the antenna radiator is not opposite to the parasitic current on the third connecting part, therefore the third connecting part becomes the parasitism of the antenna radiator, and the antenna performance of the Bluetooth earphone is improved.

Description

technical field [0001] The present application relates to the technical field of communication equipment, in particular to a bluetooth earphone. Background technique [0002] At present, Bluetooth earphones are deeply loved by users because of their advantages of convenience and compactness, and their usage range is getting wider and wider. However, in traditional Bluetooth earphones, the performance of the antenna itself is not good, and in order to meet the demands of a compact layout, it is difficult to realize the requirement of no antenna headroom or a small antenna without headroom, resulting in a decrease in the performance of the antenna. Contents of the invention [0003] The present application provides a bluetooth earphone to improve the performance of the antenna of the bluetooth earphone, ensure the communication effect of the bluetooth earphone, and meet the requirements of no-antenna clearance area or small antenna clearance area. [0004] The present appli...
