Description

Flat micro loudspeaker

Technical Field

The utility model relates to a miniature speaker field especially relates to dull and stereotyped miniature speaker.

Background

The micro speaker is a micro electroacoustic transducer, and is widely applied to electronic products such as tablet computers, MP3, MP4, notebook computers, mobile terminals, Personal Digital Assistants (PDAs), and the like. Its magnetic circuit system forms a ring magnetic gap, between which a uniform magnetic field (the magnetic induction intensity and direction are the same everywhere) is distributed. The vibration system of the loudspeaker is composed of a ring-shaped voice coil wound by a lead and a vibrating diaphragm connected with the voice coil. After the voice coil is fed with signal voltage, current is generated, the voice coil cuts magnetic lines of force, acting force is generated, the vibrating diaphragm is driven to move up and down, and the vibrating diaphragm drives air to make corresponding sound. The whole process is as follows: electro-mechanical-acoustic conversion.

At present, the voice coil and the diaphragm in the miniature loudspeaker on the market are in a separation structure, so that a gap exists between the acting force generated by the voice coil and the diaphragm, and the quality of the sound quality is not high.
