  • Patent number: 11950074
    Abstract: The present invention provides a speaker including: a frame, a vibration system and a magnetic circuit system. The vibration system includes a vibration diaphragm and a voice coil. The magnetic circuit system includes a magnetic part, and the voice coil is arranged around the magnetic part. The vibration system further includes an elastic plate with two branch elastic plates. The branch elastic plate includes a connection part, an extension part, an elastic arm and a fixed part. The surfaces of the connection part and the extension part facing the connection surface are recessed together to form a welding slot, and the lead wire is accommodated in the welding slot. The speaker provided by the present invention can not only effectively prevent the voice coil from swaying, but also reduce the number of parts to simplify the product structure.

  • Publication number: 20190230445
    Abstract: The present disclosure provides a speaker. The speaker includes a frame, a vibrating diaphragm held in the frame, and a voice coil located below the vibrating diaphragm and configured to drive the vibrating diaphragm to vibrate to produce a sound. The speaker further includes a heat insulation material layer sandwiched at a junction between the vibrating diaphragm and the voice coil. According to the speaker in the present disclosure, the heat insulation material layer is additionally disposed between the vibrating diaphragm and the voice coil. The heat insulation material layer can prevent or reduce heat transferred by the voice coil to the vibrating diaphragm when the voice coil works, thereby reducing creeping of the vibrating diaphragm caused by heat and reducing a change in F0. This increases a frequency response and improves acoustic performance of the speaker.
