Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the structural details of the embodiment of the present utility model are described in further detail:

[0017] The basic structure of the ribbon coaxial medium and high frequency loudspeaker embodiment is as follows: figure 1 As shown, it includes a ribbon tweeter unit located in the center and a midrange speaker unit located in the outer ring; the ribbon tweeter unit is composed of an annular upper magnetic plate 3, a treble annular neodymium-iron-boron magnet 19 and a U-shaped magnetic conductor. The plate 18 constitutes the magnetic circuit structure of the working magnetic field of the high-pitch dissipated. On the ring-shaped upper magnetic plate 3, a high-pitched ribbon-type planar diaphragm 4 is installed, and the entire ribbon-type tweeter unit is installed on the tweeter bracket 8. The membrane 4 is fixed on the treble bracket 8 by the treble sound membrane support frame 6, and the belt type tweeter unit is provi...

Abstract

The strap-type coaxial medium-high-frequency loudspeaker comprises: a high-pitch loudspeaker unit on center, which comprises: a magnetic circuit with all of a loop top magnetic conductive plate and a high-pitch loop Nd-Fe-B magnet and a U-shaped magnetic conductive plate, and a high-pitch strap plane diaphragm; and a mean-tone loudspeaker unit on outer loop, which comprises: a T-shaped magnetic circuit with all of a mean-tone U-shaped magnetic conductive plate and a loop magnetic conductive column and a loop Nd-Fe-B magnet, and a double arc diaphragm. This invention belongs to Hi-Fi apparatus.

Description

technical field [0001] The invention relates to a mid-high frequency loudspeaker in which a high-pitched loudspeaker and a middle-pitched loudspeaker are coaxially arranged. Background technique [0002] The currently known ribbon tweeter has a rectangular structure, using two layers of high-performance magnetic strips to form a magnetic field in the middle, sandwiching a film with a loop aluminum strip on the surface, when an alternating current passes through the aluminum strip, Under the action of the magnetic field, the aluminum strip will drive the film to vibrate up and down to push the air to produce sound. Because of the structure of the upper and lower magnetic circuits, the distance from the sound source to the radiation surface on the sounding surface is longer, and the sound groove needs to be used on the magnetic guide plate to diffuse, and there is a gap between the vertical and horizontal dimensions of the diaphragm. Therefore, from an acoustic point of view,...
