TH48559B - An ultra-low frequency transducer and a speaker? (The speaker contains an ultra-low frequency transducer.) - Google Patents

Abstract

DC60 (14/10/58) extremely low frequency transducer. Or a subwoofer for a car speaker system with a rectangular or square-shaped diaphragm. As it should be used, the perimeter of the square will coexist significantly with the In front of the speaker unit or speaker cabinet in this way The air movement in the subwoofer is maximized for its size. Designation of the cladding And the loudness of the speakers as well, as is typical, the transducer is loud Said to consist of a framework Or a frame with a four-shaped front Square to support the periphery of the diaphragm as it should be. Used to consist of sections Convex surrounds which have folded corners In order to have More durable In the diaphragm, a band is formed, such as an extremely low frequency transducer. Or a subwoofer for a car speaker system with a rectangular or square-shaped diaphragm. As it should be used, the perimeter of the square will coexist significantly with the In this way, the air movement in the subwoofer is maximized for its size. Designation of the cladding And the loudness of the speakers as well, as is typical, the transducer consists of a frame. Or a frame with a four-shaped front Square For support The periphery of the diaphragm, the diaphragm should be selected. Used to consist of enclosing parts. Convex round with folded corners In order to have More durable In the diaphragm, a strap is formed.

Claims (17)

1. An ultra-low frequency transducer consisting of a frame with a rectangular front, a concave diaphragm with a rectangular outer section sized to be supported on the front of the frame and supported for axial movement, and a driver assembly supported by the frame consisting of a permanent magnet and a reciprocating voice coil linked to the diaphragm. The voice coil is connected to the signal source, and the driver assembly is optimized to convert the signal from the source into the reciprocating axial movement of the diaphragm, thus producing an ultra-low frequency sound. 2. The transducer of claim 1, where the rectangular front of the frame and the rectangular outer perimeter of the diaphragm are both square. 3. The transducer of claim 1, whose diaphragm also includes a flexible enclosure between the outer parts of the diaphragm. 4. The transducer of claim number 3, the surrounding part of which has a convex cross-section. 5. The transducer of claim clause 4, the surrounding part of which shall be formed into a folded section which is positioned radially at least once at each corner. 6. The transducer of claim clause 4, the surrounding part of which shall be formed into folds which are positioned along a certain radius at each corner. 7. The transducer of claim clause 6, whose folding part extends outward from the said enclosure. 8. The transducer of claim number 1, the diaphragm of which shall be supplied along with a number of straps. 9. The speaker consists of a housing with a rectangular opening, an ultra-low frequency transducer consisting of a concave diaphragm with a rectangular outer section precisely sized to match the rectangular opening of the housing, the diaphragm supported for axial movement within the housing, and a driver assembly consisting of a permanent magnet and a voice coil supported in a reciprocating motion linked to the diaphragm. The voice coil is connected to the signal source, and the driver assembly is optimized to convert the signal from the source into the reciprocating axial movement of the diaphragm to produce ultra-low frequency sound. 10. The speaker of claim 9, where the rectangular opening in the enclosure and the rectangular outer part of the diaphragm are both square. 11. The speaker of claim 9, which also consists of a rigid frame with a front and rear face, the front of which is rectangular and sized to accommodate the rectangular outer portion of the said diaphragm. 12. The speaker of claim 11, whose diaphragm also contains a flexible enclosure between the outer parts of the diaphragm. 13. The speaker of claim 12, whose surrounding area shall have a convex cross-section. 14. The speaker of claim 12, whose enclosure shall be formed into folds that are positioned along the radius of at least one section at each corner. 15. The speaker of claim 13, the surrounding part of which shall be formed into folds positioned along a certain radius at each corner. 16. The speaker of claim number 15, whose hinged part extends outwards from the said enclosure. 17. The speaker of claim 9, whose diaphragm shall be supplied with a number of straps.
