Diaphragm with enhanced middle-low frequency bands

Abstract

The invention discloses a diaphragm with enhanced middle-low frequency bands. The diaphragm comprises three layers; the first layer is a coating layer, and the coating material is titanium; the second layer is a basic layer, and the basic layer is a polyarylate layer; the third layer is a composite layer, and the composite layer is a polyurethane layer; the basic layer is located between the coating layer and the composite layer, the coating layer coats the basic layer, and the basic layer after coating and the composite layer are composite to form the diaphragm; and polyarylate is adopted to coat titanium and is then composite with the polyurethane to form the diaphragm. The diaphragm of the invention has the advantages of light weight, good rigidness, and attractive appearance.

Description

technical field [0001] The invention relates to the field of loudspeaker diaphragms, in particular to a diaphragm with enhanced middle and low frequency bands. technical background [0002] At present, metal diaphragms or plastic diaphragms are mostly used in the market. The most commonly used materials for plastic diaphragms are polyethylene terephthalate (PET for short), polyethylene naphthalate (polyethylene naphthalate) , referred to as PEN), polyetherimide (Polyetherimide, PEI for short), etc. These materials are cheap and have certain practicability, but their rigidity is not good and the quality is relatively heavy, so the manufactured diaphragm midrange The quality of bass and bass is poor; the metal diaphragm is very rigid. At present, aluminum metal or its alloy products are the most used. However, the metal diaphragm is prone to "metallic sound", that is, high-frequency resonance, and the quality of the metal is relatively heavy. The sound or bass effect is relat...

[0002] At present, metal diaphragms or plastic diaphragms are mostly used in the market. The most commonly used materials for plastic diaphragms are polyethylene terephthalate (PET for short), polyethylene naphthalate (polyethylene naphthalate) , referred to as PEN), polyetherimide (Polyetherimide, PEI for short), etc. These materials are cheap and have certain practicability, but their rigidity is not good and the quality is relatively heavy, so the manufactured diaphragm midrange The quality of bass and bass is poor; the metal diaphragm is very rigid. At present, aluminum metal or its alloy products are the most used. However, the metal diaphragm is prone to "metallic sound", that is, high-frequency resonance, and the quality of the metal is relatively heavy. The sound or bass effect is relatively poor, so if you want to make a good bass or midrange diaphragm, you must solve the problem of rigidity and weight
