Description

Technical Field

[0001] The utility model relates to the field of receivers, in particular to an armature balanced receiver. Background Art

[0002] A receiver is an electroacoustic conversion device that converts electrical signals into voice signals and is usually used in electronic devices such as mobile phones, tablets, and hearing aids.

[0003] The conventional receiver has a U-shaped armature structure and a magnetic ferrule combined therewith, and the magnetic ferrule plays a magnetic role. The conventional magnetic ferrule is designed to be ring-shaped, and it is difficult to use a stacking installation method during the assembly process, which is inconvenient to install.

[0004] The Chinese utility model patent with publication number CN220693339U discloses a balanced armature receiver, including: a shell, including a bottom plate and a first side plate and a second side plate connected to the bottom plate, the first side plate and the second side plate are arranged at intervals along the length direction of the bottom plate; an ferromagnetic component connected to the bottom plate and provided with a first channel; a coil connected to the ferromagnetic component and arranged close to the first side plate, the coil is provided with a second channel, the second channel and the first channel are connected to form a third channel; a reed, including a moving part and a fixed part connected to the moving part, the moving part and the fixed part are located in the same plane, the moving part is movably arranged in the third channel, and the fixed part is connected to the ferromagnetic component.

[0005] The above-disclosed balanced armature receiver cleverly solves the problem that the ring-shaped magnetic fins are difficult to assemble by splitting the magnetic fins into two parts, an upper and a lower part. However, the upper and lower parts of the magnetic fins are connected by bent side plates to form a ring structure. When processing the two parts of the magnetic fins, they need to be stamped out into shape first and then stamped and bent, which makes the processing inconvenient. The inventors of the present invention aim to provide a solution that is more convenient to process. Utility Model Content

[0020] In an embodiment of the present invention, the upper cover includes a top plate and a connecting plate extending from the top plate toward the lower cover.

[0021] To implement the above technical solution, a cavity for accommodating the structure is formed between the upper cover and the magnetic conductor.

[0022] In an embodiment of the present invention, the cross section of the connecting plate is the same as the cross section of the side plate.
