Abstract

A single-magnet double-tone-circuit coaxial loudspeaker includes a shell, a U iron, a magnet, a spring washer, a first diaphragm assembly, a second diaphragm assembly, an upper cover and a terminal plate. A single "agnet+spring washer+U iron " magnetic circuit is extended to be two upper-lower coaxial magnetic circuits, therefore, the first diaphragm assembly and the second diaphragm assembly which are electrically connected to the terminal plate generate a double-magnetic-circuit feature by sharing a single-magnet system. High frequency and low frequency wave bands are driven independently, such that high frequency and low frequency portions can achieve a better sound resolution effect. The complementation of the two reduces distortion, thus improves the overall acoustic performance of the loudspeaker.

Description

technical field [0001] The invention relates to the technical field of loudspeaker manufacturing, in particular to a single-magnetic two-way coaxial loudspeaker. Background technique [0002] The dynamic coil speaker uses the magnetic field generated when the electrical signal enters the voice coil, and interacts with the magnetic field of the permanent magnet, and then pushes the diaphragm to vibrate the air to achieve the function of electro-acoustic conversion. [0003] Traditional dynamic speakers are usually designed with a single magnetic circuit. This single magnetic circuit system has a single diaphragm and a single voice coil, that is, all audio segments achieve electro-acoustic conversion through the vibration of a single diaphragm. The single magnetic circuit design cannot take into account the bandwidth of the treble and bass: in order to obtain the bass effect, the diaphragm of the diaphragm and the suspension system need to be flexible; on the contrary, in orde...
