Abstract

The invention discloses a low-frequency broadband high-power electric transducer, which belongs to the technical field of electric transducers. The low-frequency broadband high-power electric transducer includes a shell, a reinforced magnetic circuit mechanism, a coil frame and a vibration mechanism; the reinforced magnetic circuit mechanism includes an electrician pure iron core, an axially magnetized magnetic steel, a radially magnetized The steel and soft iron rings change the magnetic force lines passing through the air gap from the magnetic force lines generated by the single axially magnetized magnetic steel into two sets of magnetic force lines that include the radially magnetized magnetic steel, which enhances the magnetic force in the air gap The magnetic induction intensity ensures that under the same emission current, the radiation surface receives a greater excitation force, thereby improving the low-frequency emission response of the transducer. At the same time, by adding a soft iron ring on the inner wall of the radially magnetized magnetic steel, the uniformity of the magnetic field inside the air gap is ensured, the linear range of the transducer is further improved, and the large amplitude of the radiation film is guaranteed at low frequencies The lower linearity improves the broadband effect of the transducer.

Description

technical field [0001] The invention relates to the technical field of electric transducers, in particular to a low-frequency broadband high-power electric transducer. Background technique [0002] The electrodynamic transducer is a common underwater low-frequency broadband transmitting transducer. The principle of the electric transducer is the same as that of the loudspeaker in the air. It is mainly composed of two parts: the magnetic circuit structure part that generates the magnetic field; the vibration system composed of the radiation diaphragm, bracket and coil. Electric transducers generally work in the low-frequency region, and the stroke of the moving coil is relatively large. In order to reduce nonlinear distortion, a large uniform area of ​​air-gap magnetic flux density is required; the volume displacement of low-frequency transducers is large, and it is hoped to provide a large According to Ampere's law F=BiL, when the current and coil length are constant, incre...
