Problems solved by technology

These shortcomings are mainly manifested in: 1) For the connection between the guide rod and the armature, the cylindrical end is connected to the vibrating part. Due to the connection surface, the connection tends to be unstable after long-term use 2) For the connection between the guide rod and the diaphragm, it is necessary to align the position of the through hole on the guide rod and diaphragm in advance before continuing to install the top cover and other components. The installation is more troublesome and affects production efficiency

Embodiment Construction

[0026] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] In the first embodiment of the receiver with the improved guide rod structure involved in the present invention, as Figure 1-2 As shown, it includes a housing 1 and a diaphragm 2, and also includes: an armature 4, on which an iron core 3 and a coil 6 are sheathed on the vibrating part, and the armature 4 exposes the iron core 3 to form a first connection surface 42; The guide rod 5 is in the shape of a flat column or a semi-cylindrical (not shown), one end of which is fixedly connected to the diaphragm 2 , and the other end is bent and fixedly connected to the first connecting surface 42 . The invention improves the connection structure between the guide rod, the armature and the diaphragm, and the flat column or semi-cylindrical guide rod can expand the connection surface between the armature and the diaphragm, improve the stability ...

Abstract

The invention discloses a receiver with an improved guide rod structure. The receiver comprises a housing, a vibrating diaphragm, an armature, and a guide rod. An iron core and a coil are sleeved on the vibrating portion of the armature. The armature is exposed out of the iron core to form a first connecting surface. The guide rod is in a flat column or half-cylindrical shape. One end of the guide rod is fixedly connected with the vibrating diaphragm, while the other end of the guide rod is bent and then fixedly connected with the first connecting surface. The guide rod may enlarge the connecting surface between the armature and vibrating diaphragm in order to enhance connection firmness. The new connecting structure of the guide rod and the vibrating diaphragm enables a fact that alignment of the positions of guide rod and a through hole is no longer required when the receiver is installed. Therefore, easy installation is achieved and production efficiency can be improved.

Description

technical field [0001] The invention relates to a receiver, in particular to a receiver with an improved guide rod structure. Background technique [0002] The receiver is an electro-acoustic device that converts audio electrical signals into sound signals without sound leakage. It is widely used in communication terminal products to realize audio playback, mainly in mobile phones, earphones and hearing aids. When the receiver is in use, it mainly drives the guide rod through the internal driving part, and then the guide rod drives the diaphragm to vibrate to produce sound. Therefore, the quality of components such as the drive unit, guide rod and diaphragm also determines the overall performance of the receiver. [0003] At present, there are many technical developments and improvements in the drive part, but there are not many improvements in the guide rod part. In fact, the guide rod also plays a very important role in the process of feeling the performance of the receiv...
