Dual-drive sounding structure, dual-function earphone and control method thereof

Abstract

The invention discloses a dual-drive sounding structure, a dual-function earphone and a control method of the dual-drive sounding structure. A double-drive type sound production structure comprises avibrator structure used for bone conduction sound and a horn structure used for air conduction sound. The loudspeaker further comprises a magnetic conductive connecting piece arranged between the oscillator structure and the horn structure. The magnetic conductive connecting piece is provided with an oscillator side cavity used for embedding the oscillator structure and a horn side cavity used forembedding the horn structure. According to the loudspeaker, the magnetic conductive connecting piece is adopted, and the oscillator structure and the loudspeaker structure are combined together to form an integral structure, so that the loudspeaker is simple in structure and has the sense of wholeness. Besides, the oscillator structure and the horn structure are arranged back to back, and when the loudspeaker is used, audios are output in opposite directions and do not interfere with each other. In addition, the vibrator inner cover and the horn shell form the connecting groove, so that the installation is easy, and the maintenance is convenient. According to the dual-function earphone, the sound guide hole is formed in the side edge, close to the earhole, of the horn shell, so that a sound path of horn playing can be converted to face the earhole, and the horn can be played into the earhole more easily.

Description

Technical field [0001] The present invention relates to a sound structure of a headset, more specifically a double-driven sound structure and a dual function earphone and a control method thereof. Background technique [0002] The existing bone passage earphone sound quality difference has always been a common problem, and the bone conduction vibrator is supported by the shrapnel due to the no diaphragm. The operation of the elastic sheet needs to be controlled in a reasonable range, resulting in limited elastic vibration amplitude, and the frequency resonance point of the vibrator is generally All are 160-200 Hz, the bone passage earphone receives the vibration signal through the tap bone, and when the bone conductor headphone low frequency signal is strong, the vibration has caused a headache and other reasons. In addition, the traditional dynamic headphones vibrates vibrating the sound wave to the human outer ear drum film, which cannot be used in the water, and the earphones ...

AI Technical Summary

Problems solved by technology

Among them, the new bone conduction earphone with the patent number CN201920757186.3 is a dual-purpose earphone with a bone conduction unit and earplugs, but the earplugs and the bone conduction unit are not integrated, but a split structure, not only the appearance is not beautiful , and it takes up space and is inconvenient to use

Other patent documents also do not solve the unsafe problem caused by sealing the earhole when the earplug is used.
