Abstract

The invention discloses excitation earphones which comprise two earphone diaphragms, a magnetic conductive ring, a magnetic conductive column arranged inside the magnetic conductive ring, voice coil leads which are arranged between the magnetic conductive ring and the magnetic conductive column and are connected with one tail ends of the two earphone diaphragms respectively, two magnetic conductive sleeves and two excitation coils, wherein the excitation coils are in electric connection with a power source and are arranged in the space encircled by the magnetic conductive ring, the magnetic conductive sleeves and the magnetic conductive column. According to the excitation earphones provided by the invention, a coil is added on a highly magnetic conductive material through adopting the electromagnetic theory and a direct current supply manner, so as to form a traditional permanent magnet, the tone quality can be arbitrarily adjusted, and the structure is simple.

Description

technical field [0001] The present invention relates to earphones, in particular, to an excitation earphone. Background technique [0002] At present, the working principle of traditional earphones is driven by the voice coil in the permanent magnetic field, and the diaphragm connected to it moves. The coil in the permanent magnetic field is connected to the diaphragm. Driven by the signal current, the coil drives the diaphragm to produce sound. Since the structure of traditional earphones is solidified, the sound quality is single and cannot be adjusted. Contents of the invention [0003] The purpose of the present invention is to provide an excitation earphone to solve the problem of single and unadjustable sound quality in the prior art. [0004] In order to achieve the above object, the present invention provides an excitation earphone, comprising two earphone diaphragms, a magnetically permeable ring, a magnetically permeable column arranged in the magnetically perm...
