Abstract
The utility model belongs to the technical field of the electroacoustic product, concretely relates to compound acoustics complex film. The composite acoustic composite membrane comprises a base membrane and a composite membrane, and is formed by a two-layer composite structure, wherein the composite structure is formed by thermally compounding the base membrane and the composite membrane, the base membrane is thermally compounded with the composite membrane, the base membrane adopts a PEEK (polyether-ether-ketone) membrane, and the composite membrane adopts a TPU (thermoplastic polyurethane) thermoplastic elastomer rubber membrane. The beneficial effects are as follows: the PEEK polyether-ether-ketone film is thermally compounded with the TPU thermoplastic polyurethane elastomer rubber film, so that the PEEK polyether-ether-ketone film has good toughness and strength, excellent structural stability and high power-resistant reliability, and when the vibrating diaphragm is applied to a loudspeaker, the resonant frequency of the loudspeaker product can be effectively reduced, the frequency band of the loudspeaker product can be widened, and the stability of the resonant frequency of the loudspeaker product can be improved.
Description
Technical Field
The utility model belongs to the technical field of the electroacoustic product, concretely relates to compound acoustics complex film.
Background
The diaphragm is used as a sound production component in the loudspeaker, and the structure and the material of the diaphragm have great significance on the generation effect of the loudspeaker. In order to reduce the resonant frequency of a product, widen the frequency band, and improve the tone quality of a low frequency band and a high frequency band of a loudspeaker, a single-layer high polymer material is generally used for sounding in the current electroacoustic product industry; the acoustic performance is chosen more univocally and suffers from the following drawbacks:
first, the resonant frequency F0 of the product fluctuates greatly: after the loudspeaker product is assembled, the resonant frequency F0 of the product rises along with the time;
secondly, poor heat resistance: after the vibrating diaphragm is heated and molded, the surface viscosity of the vibrating diaphragm is increased, and the vibrating diaphragm is easily polluted by impurities, so that the production efficiency is influenced;
thirdly, the power resistance is poor: after the high-temperature power test, the vibrating diaphragm is easy to deform, collapse and the like.
