Embodiment 1

[0020] As shown in the figure, a receiver motor structure includes a coil 1, a yoke 2, a magnet 3 and a U-shaped reed 4. The coil 1 and the yoke 2 are sleeved on the U-shaped reed, and the coil 1 and the yoke 2 pass through the ring Oxygen glue connection, two magnets 3 are arranged in parallel on both sides of the U-shaped reed in the magnetic yoke. The coil 1 also includes coil lead wires and lead wires, and the coil is connected to the lead wires through the coil lead wires. The U-shaped reed includes a vibrating part 4.1, a bending part 4.2 and a fixed part 4.3 connected in sequence, and the end of the fixed part is provided with two extension parts 4.4, and the extension parts 4.4 are symmetrically distributed on both sides of the top end of the fixed part 4.3 , the two extension parts and the fixing part are Y-shaped, and the width of the fixing part 4.3 gradually decreases from the end to the connection end with the bending part, which can effectively reduce the stress ...

Abstract

The invention discloses a motor structure of a telephone receiver. The motor structure comprises a coil, a magnet yoke, magnets and a U-shaped reed; the coil and the magnet yoke sleeve the U-shaped reed; the two magnets are arranged at two sides of the U-shaped reed in the magnet yoke in parallel; the coil is connected with an outgoing line through a coil lead; the U-shaped reed comprises a vibration part, a curved part and a fixed part connected in sequence; a single-surface copper clad PCB (Printed Circuit Board) is arranged on the fixed part; and the coil lead is connected with the outgoing line through the single-surface copper clad PCB. The single-surface copper clad PCB is used as a bridging medium; the manufacturing process is simple, little damage to the coil and low in cost; furthermore, the width of the fixed part of the U-shaped reed is gradually reduced from the tail end to the connection end with the curved part; and thus, mechanical shock stress concentration of the U-shaped reed is lessened.

Description

technical field [0001] The present invention relates to a receiver motor structure. Background technique [0002] The motor of the receiver includes a coil, a yoke, a magnet and a U-shaped reed. The coil is combined with the yoke as an independent unit, and the coil is connected to the lead wire through the coil lead wire. At present, in the production of connecting the coil lead wire and the lead wire, the coil lead wire is wound on the lead wire at least three times, and then soldered together. This process is purely handmade, very complicated and the coil lead wire is thin, which is very easy to break during the process of winding the lead wire. Thus, the cost and scrap of the coil is very serious. Contents of the invention [0003] The invention provides a receiver motor structure in order to solve the deficiencies in the prior art. The coil lead wire and the lead wire are easy to connect and fixed firmly, which can realize automatic production and greatly increase t...
