  • Loudspeaker comprising a rigid membrane connected to at least two coils
    Patent number: 11632631
    Abstract: A loudspeaker (10) comprising a magnetic circuit (12), and a mobile assembly (14) along an axis (D) comprising: a rigid membrane (42) defining an external diameter (D3), a first reel holder (44) and a second reel holder (46), at least a first coil (22) and a second coil (24) located in a first air gap (18) and a second air gap (20) of the magnetic circuit respectively. The first coil holder and the second coil holder form a first junction (54) and a second junction (56) with the membrane, concentric and defining a first diameter (D1) and a second diameter (D2) greater than the first. The second diameter is: less than 97% of the external diameter, or greater than or equal to 97% of the external diameter, the first diameter being greater than 40% of the external diameter.
