The mounting groove 213 is defined in the lower portion of the first outer casing 211 and communicates with the receiving cavity 22 . The fixing grooves 214 are respectively formed on the inner surface of the first outer casing 211 on opposite sides of the mounting groove 213 .

The mounting member 11 is fixed in the mounting groove 213 and is made of a plastic material. Specifically, a recessed portion 111 is defined in a middle portion of the outer surface of the mounting member 11. The inner surface of the mounting member 11 is provided with a plurality of fixing ribs 112 corresponding to the notches 111, and each of the fixing ribs 112 defines a receiving groove 113. At least one fixing portion 114 is protruded from the mounting member 11 , and each of the fixing portions 114 is correspondingly fixed in a fixing groove 214 .

Referring to the first to fourth figures, the first radiating portion 12 is made of a metal material, wherein the metal material is preferably aluminum or copper. The first radiating portion 12 has a feeding end 121 extending from the inside to the outside in a rectangular plate shape, and the end of the feeding end 121 is connected with a connecting portion 122 which is bent downward and outward and then obliquely extends, and the connecting portion 122 The end connection has an extension 123 that extends upwardly and outwardly and then extends to one side. The feeding end 121 is disposed in the receiving cavity 22 of the Bluetooth headset 200. The free end of the feeding end 121 is fixed on the circuit board and connected to the antenna circuit. The extending portion 123 of the first radiating portion 12 is fixed to the mounting member 11 The inner surface of the receiving groove 113.
