Title:
HYBRID SPEAKER
Document Type and Number:
WIPO Patent Application WO/2018/236140
Kind Code:
A1
Abstract:
The present invention relates to a hybrid speaker wherein a dynamic low-volume sound speaker and an electro-magnetic high-volume sound speaker are coaxially coupled to each other by a housing; the electro-magnetic high-volume sound speaker and the dynamic low-volume sound speaker have respective permanent magnets arranged in the same magnetic direction such that the permanent magnets can be magnetized once after the high-volume sound speaker and the low-volume sound speaker are separately assembled and coaxially coupled before the respective permanent magnets are magnetized; and upper magnetic energy of a low-volume sound permanent magnet of the low-volume sound speaker is provided to be also used as a driving bias for the electro-magnetic high-volume sound speaker such that the high-volume sound speaker is allowed to be free of a lower permanent magnet of a pair of upper and lower permanent magnets constituting a magnet circuit of the high-volume sound speaker. Therefore, the hybrid speaker can be usefully applied to a speaker field.
