Description of the Invention: [Technical Field] The present invention relates to a fixed structure, particularly to an earpiece fixing structure for a portable electronic device such as a mobile phone. [Prior Art] The use of portable electronic devices such as mobile phones and personal digital assistants (PDAs) is becoming more and more widespread, and consumers are increasingly demanding the functions and longevity of these products. In the prior art, the fixing of the circuit board of the portable electronic device is usually performed by fixing the circuit board by the connection of the connecting hole provided on the main body of the circuit board and the connecting rod of the machine body, such as a bolt. On the housing of the portable electronic device. The earpiece module of the portable electronic device achieves its function by contacting two metal domes disposed thereon with contact points on a flexible circuit board. However, in order to save product space, the fixed structure of the fixed flexible circuit board and the earpiece module is usually not provided, and the flexible circuit board and the earpiece module are sandwiched only by the mounting of the circuit board and the housing. Therefore, due to the assembly accuracy problem, the flexible circuit board is easily touched by the earpiece module during use: the metal spring bounces up, resulting in poor contact between the flexible circuit board and the earpiece module. The contact positioning is not accurate, thus affecting the function of the product. [Summary of the Invention]

The fixing cover 16A includes a main body plate 1601 having a substantially rectangular plate shape, and a plurality of engaging ridges and a positioning portion 164 extending from the main body plate 16〇1. In the embodiment, the fixing cover 16 is provided with the first engaging portion 161, the second engaging portion 162 and the third engaging portion 163. The first engaging portion i61 and the second portion are provided. The engaging portion 162 and the second engaging portion 163 are each a rectangular plate-like joint 201008219 in which a rectangular holding hole 165 is opened. The first engaging portion 161 and the second engaging portion 162 are spaced apart from each other at the end portion of the main body plate 1601, and are each formed by bending one end portion of the main body plate ι6〇1 vertically. The first engaging portion 161 and the second engaging portion 162 correspond to the two notches 153, 154 of the flexible circuit board 15. The third engaging portion 163 is formed by vertically bending one end of the main body plate 1601 opposite to the end portion of the first and second engaging portions ι 61 and ι 62. The third engaging portion 163 is sized and the mounting hole 152. The size is equivalent. The ends of the first engaging portion 161, the second engaging portion 162, and the third engaging portion 163 are all bent inward to form a guiding surface 166. The positioning portion 164 is substantially in the shape of an "L" plate, and is formed by a first plate 1641 perpendicularly connected to the main body plate 1601 and a second plate 1642 provided with a positioning hole 1643. The plurality of engaging blocks are engaged with the plurality of engaging portions of the fixing cover 16 , and in the embodiment, the three engaging portions 161 , 162 , 163 ′ corresponding to the fixing cover 16 are provided with three engaging portions. Piece. The three engaging blocks are wedge-shaped blocks, and are respectively a first engaging block 167, a second engaging block 168, and a second blocking block 169. The first engaging block 167 and the second engaging block (10) are spaced apart from the inner wall of the third slot wall 1153 of the fixing slot 115 for respectively engaging the first engaging portion 161 and the second card of the fixing cover 160.
