Description

R ring internal oblique loudspeaker

Technical Field

The utility model relates to a speaker field, specifically speaking relates to an interior oblique speaker of R ring.

Background

The loudspeaker is a transducer for converting an electric signal into an acoustic signal, and the performance of the loudspeaker has great influence on the sound quality. The loudspeaker is the weakest component in the audio equipment, and is the most important component for the audio effect. Loudspeakers are of a wide variety and vary widely in price. The audio frequency electric energy makes the cone or diaphragm vibrate and generate resonance (resonance) with the surrounding air to make sound through electromagnetic, piezoelectric or electrostatic effect. The loudspeaker is divided into an external magnetic type and an internal magnetic type according to whether the magnet is exposed or not, the magnet between the washer and the central iron column can be seen from the outside by the external magnetic type loudspeaker, and the external magnetic type loudspeaker is generally large in size and weight and can form a strong magnetic field; the magnet is wrapped in the shell, so that the magnet cannot be seen from the outside, and the loudspeaker is small in size, light in weight and strong in external magnetic interference resistance.

The R ring is a suspended edge structure used for fixing the drum paper on the basin frame, and the sound quality of the loudspeaker is greatly influenced by combining the shape of the drum paper. For example, utility model patent application No. 202121381203.1 discloses a powerful ultra-thin speaker, utilizes anti-concave R dangling limit structure, combines two sharp composite construction on the drum paper structure, and is small, and realizes the high-quality tone quality output of low frequency under the high-power condition, but this kind of structure does not solve traditional speaker high frequency unsmooth, has the not enough of burr sense. Therefore, a need exists for a loudspeaker with a smooth high frequency and an inclined R-ring.
