| 发明名称 | Dual coil loudspeaker system | ||
| 摘要 | A dual coil loudspeaker system having a voice coil having a first coil configured to receive a first electrical signal from a first source, and a second coil configured to receive a second electrical signal from a second source different from the first source; a field magnet configured to generate a magnetic field that interacts with magnetic fields created by the first coil and the second coil; and a diaphragm connected to the voice coil such that the diaphragm is displaced in response to energization of at least one of the first coil and the second coil. | ||

| 主权项 | 1. A dual coil loudspeaker system comprising: a voice coil having a first coil configured to receive a first electrical signal from a first source, and a second coil configured to receive a second electrical signal from a second source different from the first source; a field magnet configured to generate a magnetic field that interacts with magnetic fields created by the first coil and the second coil; a diaphragm connected to the voice coil such that the diaphragm is displaced in response to energization of at least one of the first coil and the second coil; and the voice coil including a tube connected to the diaphragm, and wherein the first coil and the second coil are mounted on the tube such that the second coil is adjacent the first coil in a radial dimension of the tube. | ||
