Abstract: A rotary tweeter mounting arrangement used in a speaker assembly is disclosed to include a hollow holder member affixed to a T-iron of the speaker assembly and having a cup portion at the top, a semispherical carrier member rotatably supported on the cup portion of the hollow holder member, a circular spring plate mounted in a lower part inside the carrier member, a screw inserted through a center mounting hole of the circular spring plate and a center through hole of the semispherical carrier member to pivotally secure the semispherical carrier member to the hollow holder member, and a face panel fastened to the semispherical carrier member to hold a tweeter for allowing rotation of the tweeter with the face panel and the semispherical carrier member relative to the hollow base member.

Abstract: A cooling arrangement for voice coil of speaker is disclosed to include a first bearing cup, a second bearing cup inserted into a top opening of the first bearing cup with a top flange thereof stopped at the top side of the first bearing cup to support a voice coil inside the first bewaring cup, and a conical outer holding down cup sleeved onto the first bearing cup to hold down a damper on a bottom flange of the first bearing cup and having a top edge bonded to a cone paper.

Abstract: A tweeter sound source angle adjustment arrangement is disclosed to include a holder member fastened to a T-iron of a speaker assembly and having a top recess and a through hole cut through the top recess, a face panel fastened to the holder member to secure a tweeter to the top recess of the holder member, a hub, which has a top round cup portion and a tubular bottom shank downwardly extending from the top round cup portion, a cushion ring set between the face panel and the hollow hub, and a sliding ring set in the top round cup portion of the hub and freely rotatable in the top round cup portion of the hub.

Abstract: A speaker having a heat-transfer upper bearing cup fastened to the bottom side of the cone paper, a bottom bearing cup set between the heat-transfer upper bearing cup and the damper, and a heat-transfer sound coil holder capped on the sound coil with bottom hooks thereof fastened to the heat-transfer upper bearing cup and the damper to establish with the heat-transfer upper bearing cup a heat dissipation structure for quick dissipation of heat from the sound coil during the operation of the speaker, thereby raising the output power.

Abstract: 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.

Abstract: A tweeter sound source angle adjustment arrangement is disclosed to include a holder member fastened to a T-iron of a speaker assembly and having a top recess and a through hole cut through the top recess, a face panel fastened to the holder member to secure a tweeter to the top recess of the holder member, a hub, which has a top round cup portion and a tubular bottom shank downwardly extending from the top round cup portion, a cushion ring set between the face panel and the hollow hub, and a sliding ring set in the top round cup portion of the hub and freely rotatable in the top round cup portion of the hub.

Abstract: A speaker cabinet assembly is disclosed to include a main cabinet, which is covered with a face panel and a grille in the face panel for carrying a tweeter and a woofer and having a through hole at one side and a tubular flange protruded from the outside wall around the through hole, a sub cabinet, which has a through hole at one side and a tubular flange protruded from the outside wall around the through hole, and a flexible tubular connector is connected between the tubular flange of the main cabinet and the tubular flange of the sub cabinet to guide sound waves from the main cabinet into the sub cabinet.

Abstract: A speaker damper mounting structure used in a speaker to hold a damper firmly to a voice coil is disclosed to include an upper bearing cup, which is fastened to the paper cone of the speaker to hold the damper around the voice coil and having an inner horizontal segment, an annular flange perpendicularly downwardly extending from the inner horizontal segment and inserted through the center through hole of the damper, and a plurality of locating holes cut through the inner horizontal segment corresponding to respective mounting holes of the damper, and a bottom bearing cup, which has an inner step stopped at the bottom side of the damper against the upper bearing cup and a plurality of top hooks respectively inserted through the mounting holes of the damper and fastened to the locating holes of the upper bearing cup.

Abstract: A rotary tweeter mounting arrangement used in a speaker assembly is disclosed to include a hollow holder member affixed to a T-iron of the speaker assembly and having a cup portion at the top, a semispherical carrier member rotatably supported on the cup portion of the hollow holder member, a circular spring plate mounted in a lower part inside the carrier member, a screw inserted through a center mounting hole of the circular spring plate and a center through hole of the semispherical carrier member to pivotally secure the semispherical carrier member to the hollow holder member, and a face panel fastened to the semispherical carrier member to hold a tweeter for allowing rotation of the tweeter with the face panel and the semispherical carrier member relative to the hollow base member.

Abstract: A cooling arrangement for voice coil of speaker is disclosed to include a first bearing cup, a second bearing cup inserted into a top opening of the first bearing cup with a top flange thereof stopped at the top side of the first bearing cup to support a voice coil inside the first bewaring cup, and a conical outer holding down cup sleeved onto the first bearing cup to hold down a damper on a bottom flange of the first bearing cup and having a top edge bonded to a cone paper.
