Acoustic structure with passive vibrating diaphragm unit

The invention provides an acoustic structure with a passive vibrating diaphragm unit. The acoustic structure comprises a loudspeaker unit, the passive vibrating diaphragm unit and a radiant tube, wherein the passive vibrating diaphragm unit is located at the back of a sound cone of the loudspeaker unit, the radiant tube is arranged on the side face of the loudspeaker unit, one end, exposed in air, of the radiant tube is located on the periphery of the sound cone of the loudspeaker unit and is consistent with the loudspeaker unit in orientation, the passive vibrating diaphragm unit is driven by the loudspeaker unit to vibrate, acoustic waves generated through vibration of the passive vibrating diaphragm unit are emitted through the radiant tube and a radiation port and reach the approximately same sound production point with the loudspeaker unit, the sound production effect of gamut approximate point sound sources is achieved, the phase difference of sound production of the sound cone of the loudspeaker unit and sound production of the passive vibrating diaphragm unit is reduced, and the sound positioning aspect is greatly enhanced. The invention further provides a compact type voice frequency radiation module with the structural design and a loudspeaker box with the structural design.

Four-model resonator-based compact dual-passband high-temperature superconductive filter

InactiveCN103367843AMeet filter requirementsGuarantee the effect of the stop bandWaveguide type devicesCommunications systemCompact Pattern
A four-model resonator-based compact dual-passband high-temperature superconductive filter is characterized by comprising an outer ring half wavelength hairclip resonator, an open circuit T type spiral branch, a first open circuit spiral branch, a second open circuit spiral branch, an input end and an output end; the open circuit T type spiral branch is arranged in the outer ring half wavelength hairclip resonator symmetrical about the open circuit T type spiral branch; the first and second open circuit spiral branches are arranged in the outer ring half wavelength hairclip resonator, and are symmetrical about the open circuit T type spiral branch; and the distance between the first open circuit spiral branch and the open circuit T type spiral branch is the same as that between the second open circuit spiral branch and the open circuit T type spiral branch; and the input end and the output end are in gap coupling with the outer ring half wavelength hairclip resonator. The four-model resonator-based compact dual-passband high-temperature superconductive filter can meet the communication system filtering demands on signals in non-adjacent wavebands, is small in size, simple and compact in structure, flexible in design and has an ultrahigh Q value.
