Double-diaphragm vibration horn system

Abstract

The invention discloses a double-diaphragm vibration horn system. The double-diaphragm vibration horn system comprises a shell; a metal elastic sheet which comprises an outer ring body, an elastic body and an inner ring body which are fixed in the shell and are integrally connected; a large magnetic circuit assembly which comprises a large basin stand fixed in the inner ring body, a magnet, a large washer and a large copper ring, wherein the magnet, the large washer and the large copper ring are fixedly arranged in the large basin stand in a penetrating manner; a large voice diaphragm which isinstalled at the lower end of the large copper ring, wherein a large voice coil at the upper end of the large voice diaphragm extends into a gap between the large basin stand and the magnet; a smallmagnetic circuit assembly which comprises a small basin stand fixed at the upper end of the large basin stand, a magnet fixedly arranged in the small basin stand in a penetrating manner, a small washer and a small copper ring; a small voice diaphragm which is mounted at the upper end of the small copper ring, wherein a small voice coil at the lower end of the small voice diaphragm extends into a gap between the small cone frame and the magnet; a small protective cover assembly which is fixed at the upper end of the shell; and a large protective cover assembly which is fixed at the lower end ofthe shell. The large basin stand, the small basin stand, the magnet, the large washer, the small washer and the inner ring body are fixed together and can vibrate up and down along with up-down vibration of the large voice diaphragm and the small voice diaphragm.

Description

Technical field: [0001] The invention relates to the field of acoustic technology, in particular to a double-diaphragm vibrating horn system. Background technique: [0002] Earphones are popular portable audio devices, but the existing common earphones have poor sound effects and do not have the vibration effect of heavy bass. [0003] The earphones in the prior art only have a sound membrane. When the earphone is working, the sound membrane vibrates to emit sound. , sci-fi movie blockbusters, or playing gun battles and action games, it is impossible to experience real vibration waves to hear more exciting heavy bass effects such as gunfire, war, and flight, and it is difficult to meet the needs of consumers. [0004] In view of this, the inventor proposes the following technical solutions. Invention content: [0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a double-diaphragm vibrating horn system. [0006] In or...
