Abstract

The invention relates to a hyper-linear loudspeaker which comprises a basin frame, a magnetic circuit system and a vibration system, the magnetic circuit system and the vibration system are arranged on the basin frame, the magnetic circuit system comprises a central magnetic part and a side magnetic part, and a magnetic gap is formed between the side magnetic part and the central magnetic part. The vibration system comprises a voice coil which sleeves the periphery of the central magnetic part and penetrates into the magnetic gap along the vertical direction, a centering support sheet which isadhered to the lower side of the voice coil through conductive glue and is supported on the basin frame, and a first vibration film of which the lower side is propped against the upper end of the voice coil; And a voice coil lead on the voice coil supports and is fixedly connected with the centering support sheet through conductive glue, and the voice coil lead is electrically connected with a circuit configured on the centering support sheet. Conductive glue comprising: 40%- 60% of UV resin, 10%-20% of acrylamides and / or acrylate monomers, and 5%-10% of cross-linking agent, and 1%- 2% of initiator, and 1%-3% of dispersing agent and 10%-20% of conductive filler and 5%-10% of ethanol. The voice coil and the centering support sheet are adhered by the conductive glue and are connected stably, so that the voice coil and the centering support sheet vibrate synchronously, and higher frequency response and lower distortion are obtained.

Description

technical field

[0001] The invention relates to the technical field of electroacoustic conversion devices, and relates to a super-linear loudspeaker. Background technique

[0002] The loudspeaker is an important acoustic component in electronic equipment, and it is a transducer device that converts electrical signals into acoustic signals. The existing loudspeaker module includes a casing, a magnetic circuit system and a vibration system arranged in the casing, and the vibration system includes a diaphragm and a voice coil arranged under the diaphragm. The voice coil drives the diaphragm to produce sound under the vibration of the magnetic circuit system.

[0003] The lead wire is generally led out from one side of the voice coil body, and the lead wire will inevitably generate traction on the voice coil and diaphragm. To achieve good characteristics (low distortion and abnormal sound) and high-quality hearing of dynamic speakers, the vibration system and the magnetic circ...
