Description

Technical Field

[0001] The invention relates to the technical field of loudspeaker dust cap processing, in particular to a paint spraying device for producing and processing loudspeaker dust caps. Background Art

[0002] A loudspeaker, also known as a "horn", is a very commonly used electroacoustic transducer device. It can be found in all electronic and electrical devices that make sound. A loudspeaker is a transducer device that converts electrical signals into acoustic signals. The performance of the loudspeaker has a great influence on the sound quality. Audio energy vibrates the cone or diaphragm through electromagnetic, piezoelectric or electrostatic effects and resonates with the surrounding air to produce sound. The loudspeaker is the weakest device in the audio equipment, but it is also the most important component for the sound effect. Generally, a dust cap is installed on the outside of the speaker, but the current dust cap is The dustproof and anti-magnetic materials are not effective, and dust and magnetic materials can easily enter the inside of the dust cap, causing the voice coil to get stuck and shortening the service life of the speaker. In order to more effectively prevent this situation, the outer surface of the speaker dust cap can be painted. The painting will not affect the normal operation of the dust cap, and can make the dust cap dustproof, water-resistant, oil-resistant, anti-static, and quick-drying, so that the dust cap has better barrier effect. The current dust cap painting is generally manual painting or equipment painting.
