Problems solved by technology

[0003] Chinese patent CN101213868B discloses a loudspeaker, a loudspeaker device using the loudspeaker, and an electronic device and a vehicle using the loudspeaker. The loudspeaker is used in audio equipment and video equipment, and even a small loudspeaker device can achieve good bass reproduction, but this This kind of speaker can only reproduce bass. From an acoustic point of view, there are problems of amplitude limitation and distortion. The journey from the sound source to the radiation surface on the sounding surface is long, and it cannot be designed as a mid-high frequency, so its high-frequency part cannot be achieved. 20000 Hz

Abstract

The invention discloses an intermediate sound frequency and high sound frequency integrated loudspeaker, belongs to the technical field of loudspeakers, and aims at solving the problems that an existing loudspeaker is large in size and thickness and has amplitude limitation and distortion. The intermediate sound frequency and high sound frequency integrated loudspeaker is technically characterizedby comprising a loudspeaker frame, a diaphragm, a voice coil shell, a magnetic conducting column, an anti-magnetic shielding cover, a damper and a loudspeaker chassis; a high-sound frequency diaphragm is installed in the voice coil shell, the middle of the high-sound frequency diaphragm is connected with a dust cover, the magnetic conducting column is arranged below the dust cover, an annular neodymium iron boron magnet is arranged on the magnetic conducting column, an annular upper magnetic conducting plate is arranged on the annular neodymium iron boron magnet, and the bottom of the magnetic conducting column is connected with a post; and the damper is installed on the portion, on the outer side of the anti-magnetic shielding cover, in the loudspeaker frame and provided with a pluralityof folds which are distributed in a concentric circle mode, and the diaphragm is installed on the portion, above the damper, in the loudspeaker frame. The intermediate sound frequency and high soundfrequency integrated loudspeaker has the advantages of being small in size, high in diaphragm intensity and capable of generating the intermediate sound frequency and the high sound frequency, and then the design requirements of a full-frequency loudspeaker can be met.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a mid-high audio integrated loudspeaker. Background technique [0002] In recent years, with the development of the electronic technology industry and material science, all kinds of electronic products have been developed in the direction of thinner and smaller, but the speakers used in electronic products such as TV sets, car audio, etc. Placed on the outside of the vibrating plate, resulting in a larger volume and thicker thickness, there are problems of amplitude limitation and distortion. Because the loudspeaker diaphragm in the prior art is mainly driven by the loudspeaker voice coil in the magnetic field, when the coil of the loudspeaker voice coil is energized, the loudspeaker diaphragm can vibrate together with the loudspeaker voice coil in the magnetic field to generate sound pressure. The more powerful the speaker, the louder it will sound. Therefore, the perform...
