Problems solved by technology

Based on the fact that it is difficult for the bone conduction driver to transmit in the medium and long distance, and to have a wide voice band in the medium and long distance transmission, the traditional bone conduction driver uses a diaphragm structure or directly contacts the surface of the object, which is difficult to use. leaking sound
Existing bone conduction drivers are also cumbersome to use

Abstract

The invention relates to the field of a sounder and specifically discloses a medium-distance bone conduction driver, comprising a suspension system, a vibration system, a magnetic bowl, a back cover, a mild contactor, a first voice coil, a second voice coil and a magnetic conductive bracket, wherein the suspension system is fixedly connected with the upper surface of the magnetic conductive bracket; the mild contactor is stuck with the upper part of the magnetic conductive bracket; the magnetic bowl is ring-shaped and is used for surrounding the vibration system; the lower surface of the magnetic bowl is fixedly connected with the back cover; the upper surface of the magnetic bowl is fixedly connected with the suspension system; the first voice coil and the second voice coil are fixed on the upper surface of the back cover. Double magnetic circuits are used to drive the vibration system to work, and the suspension system is used to match with the work, so the amplitude is larger and the driving force is larger. The medium-distance bone conduction driver is more suitable for transmitting medium-distance bones, and the driving force is twice as that of a single driver.

Description

technical field [0001] The invention relates to the field of sound generators, in particular to a medium-long distance bone conduction driver. Background technique [0002] The sound passes through the skull, and the jaw bone can also be transmitted to the auditory nerve, causing hearing. In science, this conduction method of sound is called bone conduction. Based on the fact that it is difficult for the bone conduction driver to transmit in the medium and long distance, and to have a wide voice band in the medium and long distance transmission, the traditional bone conduction driver uses a diaphragm structure or directly contacts the surface of the object, which is difficult to use. leaking sound. Existing bone conduction drivers are also cumbersome to use. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned technical problems, the present invention provides a medium-long distance bone conduction driver and its use method, whi...
