Abstract
The invention discloses an air power vibration horn driving unit and a head wearing type earphone thereof. The horn driving unit comprises a vibrating film, a voice coil, a washer, magnetic sheets, U-shaped iron, a bracket, a vibrating ring and a closed rear cover, wherein the bracket is arranged on the U-shaped iron. The vibrating ring is connected between the bracket and the closed rear cover. A sealed vibrating cavity is formed by the closed rear cover, the bracket, the vibrating ring and the U-shaped iron. The vibrating diaphragm is arranged at the front end of the bracket. A fist through hole communicated with the vibrating cavity is formed in the bracket of the rear portion of an outer ring of the vibrating diaphragm. Due to the fact that the vibrating ring, the closed rear cover, and the first through hole corresponding to the vibrating diaphragm are adopted, when the vibrating diaphragm sounds, airflow triggered by the vibration is conducted to the vibrating ring through the first through hole, the vibrating ring is driven to produce intense vibration, and effects that are capable of producing vibrating senses of an earphone are achieved. The vibration completely depends on airflow produced in the process of the sound production of the horn driving unit, thus consumption of electric current and voice frequency power is avoided.
