A dual loop speaker having a low profile is disclosed to include a bracket holding a magnet and a U-yoke around the magnet, a damper connected between the bracket and the U-yoke, a cone paper connected between the bracket and the damper and having an inside step, a dust cover bonded to the inside step of the cone paper, a sound coil mounted inside the dust cover and sleeved onto the magnet with the periphery thereof connected to the dust cover, and a tweeter mounted inside the sound coil. When electric current is connected to the sound coil to excite the magnet, the sound coil is cause to vibrate the cone paper and the damper, and the vibration of the cone paper causes sound. Because the sound coil is provided above the cone paper, the height of the speaker is minimized.
A dual loop speaker, comprising a bracket, a magnet, a U-yoke, a sound coil, a damper and a cone paper, wherein said cone paper comprises a locating portion, a dust cover bonded to said locating portion to hold said sound coil inside said cone paper around said magnet for causing vibration of said cone paper to produce sound upon connection of an electric current to said sound coil;
