Problems solved by technology

[0004] However, existing ribbon loudspeakers cannot be directly used in the design of full-band coaxial loudspeakers
The main reason is that the existing ribbon loudspeaker design has the disadvantage of narrow available bandwidth
If it is used in a full-band design, it needs to expand its high-pitched frequency band, and then it needs to increase the diaphragm size of the ribbon speaker, but because it is a coaxial speaker, it also leads to the diameter of the bass voice coil on the outside of the tweeter diaphragm. The increase of the frequency will lead to the reduction of the highest cut-off frequency of the low frequency band, which will directly lead to the inability to connect the treble, midrange and bass to become a good full-range system
Therefore, there is currently no full-band coaxial speaker designed with a ribbon speaker

Abstract

The invention relates to a band loudspeaker and a full-band coaxial speaker. The band speaker includes a magnetic board, an alnico, a magnetic ring and a diaphragm covered with loops, which are all annular. The magnetic board locates on the upper surface of the alnico. The magnetic ring is outside the alnico and forms magnetic gap with the magnetic ring where the diaphragm is. The full-band coaxial speaker consists of treble, alto and bass loudspeakers which are coaxial. Among them, the treble one is the band loudspeaker.

Description

technical field [0001] The invention relates to a ribbon loudspeaker and a full-band coaxial loudspeaker. Background technique [0002] Full-range speakers include tweeters, midrange speakers, and woofers. The full-range loudspeaker can achieve the full-range playback that can be heard by the human ear through the reasonable connection of the high-middle and low-frequency frequencies. In the coaxial full-range speakers, the above three speakers share a central axis, and are arranged in the order of tweeters, midrange speakers, and woofers from inside to outside. [0003] A ribbon speaker is a speaker with a good treble effect and a flat frequency response at high frequencies. The existing ribbon speaker is as described in CN03224550. This utility model discloses a ribbon speaker. The magnetic circuit structure is composed of an annular upper magnetic plate, a ring magnet and a lower T-shaped magnetic plate with a central magnetic column. The central magnetic column of the...
