Technical Field
[0001] The utility model belongs to the technical field of loudspeakers, and in particular relates to a loudspeaker iron core with an insulating structure. Background Art
[0002] The loudspeaker is generally composed of three parts: a magnetic circuit system (permanent magnet, iron core, magnetic conductive plate), a vibration system (paper cone, voice coil) and an auxiliary support system (centering support, basin frame, pad edge). The voice coil is directly defined as a coil through which current passes through the loudspeaker. It is an important component of the mechanical wave system of an electric loudspeaker and can be said to be the heart of the loudspeaker. In the process of the voice coil vibrating rapidly around the iron core, static electricity is easily generated. The static electricity generated by the iron core and the voice coil can easily cause damage to the loudspeaker or electronic devices in the equipment. Therefore, a new loudspeaker iron core with an insulating structure is designed to change the above technical defects. Utility Model Content

[0007] When the loudspeaker core of the present technical solution is used, the working core body and the voice coil with rapid vibration of the voice coil generate static electricity. The long rod screw is screwed into the thread hole to connect, and the long rod screw connects the static electricity wire to the core body. Then the mounting base is used in conjunction with the mounting hole to be installed on the device housing with screws for grounding. When static electricity is generated, it is conducted to the mounting base and the device housing through the static electricity wire for grounding and release, thereby achieving static electricity release on the core body to achieve insulation. The static electricity wire is wrapped and fixed to the device through the use of a storage wire ring and a support fixing strip to prevent the static electricity wire from vibrating and swaying or touching external equipment due to the vibration of the loudspeaker. This solves the technical problem that static electricity is easily generated during the working process of the traditional voice coil vibrating rapidly around the core, and static electricity generated by the core and the voice coil is easily damaged by the loudspeaker or electronic devices in the device.

[0009] Furthermore, the inner ring of the limiting ring is provided with an oblique groove, and the oblique groove is in a trumpet shape. By setting the oblique groove, the central opening area of the limiting ring is increased, which facilitates the insertion of the long rod screw into the limiting ring for installation.

[0024] Among them, the positioning mechanism includes a positioning clamp 17, and the positioning clamp 17 is rotatably installed on the outer surface of the long rod wire column 14.
