Technical Field

The utility model relates to a sound equipment technical field particularly relates to a speaker sound basin and speaker, audio amplifier.

Background

A loudspeaker is a transducer device that converts an electrical signal into an acoustic signal. When different electronic energy is transmitted to the voice coil, the voice coil generates magnetic field interaction between the energy and the magnet, the interaction causes vibration of the cone, the electronic energy changes at any time, the loudspeaker moves forwards or backwards, and therefore the cone of the loudspeaker moves along with the movement, and the density degree of air is changed by the actions to generate sound.

As a sound production structure, a speaker is widely used in a mobile phone, a television, a sound box, or other structures, however, as the living standard of people increases, the functional quality of the speaker is more and more required.

In the conventional loudspeaker, the sound cone is generally made of paper, plastic, Kevlar (Kevlar) or metal, and from the principle and result of use, the use of a single material or single layer of material is not the best sound radiation mode, which has the same or similar problems. Paper is a light material, and although damping is satisfactory among various materials, the rigidity is poor, sound is affected by the sound to generate sound pollution, and the bandwidth is not easy to widen; the plastic is a material with heavier mass, the internal damping is better, the rigidity performance is good, but the quality of sound tends to lack details and precision because of the larger self weight and the special properties of the material; the Kevlar basin meets the requirement on rigidity, but because of the properties of the material, dull and non-gloss plastic sound dyeing is easily caused; the metal basin has high rigidity, high density and low damping, is not favorable for the reproduction of human voice and causes obvious metal voice.
