The coil is received in the frame body. The coil is ring shaped, and a central through hole is axially passing through the coil. The damping member is securely assembled in the frame body and disposed above the coil. The permanent magnet is pillar shaped. One end of the permanent magnet is securely assembled to the damping member, and the other end of the permanent magnet is extended into the central through hole without touching the coil. The vibrating diaphragm is securely assembled in the frame body and includes a central vibrating portion. The central vibrating portion is securely assembled to the permanent magnet. | 12-25-2014 |
20140270313 | EARPHONE FOLDING DEVICE AND ASSEMBLY THEREOF - An earphone folding device and assembly thereof is provided, and includes a first head strap, a second head strap, a connecting base, a pivoting shaft, an elastic member and a button. When the elastic member is in a status of release, the elastic member is abutted against the button, so that the engaging portion is fastened with the engaging block, and the first head strap and the second head strap are positioned in a coaxial position. When the pressing portion is pressed, the elastic member is in a status of compression, so that the engaging portion is detached from the engaging block, and the second head strap is rotated about the pivoting shaft so that the first head strap and the second head strap are positioned in a parallel position. | 09-18-2014 |
20140169583 | DUAL-FREQUENCY COAXIAL EARPHONE - A dual-frequency coaxial earphone includes an earphone housing, a moving coil loudspeaker unit and a balanced armature loudspeaker unit. The earphone housing has a receiving space and an acoustic output orifice. The receiving space communicates with the acoustic output orifice. The moving coil loudspeaker unit is assembled in the receiving space and includes a moving coil vibrating diaphragm and an acoustic transmitting member. The moving coil vibrating diaphragm is assembled to face the acoustic output orifice and includes a central vibrating portion. The acoustic transmitting member includes an acoustic transmitting hole corresponding to the central vibrating portion. The balanced armature loudspeaker corresponds to the moving coil loudspeaker unit and includes an armature vibrating diaphragm. The armature vibrating diaphragm corresponds to the acoustic transmitting hole, so that the armature vibrating diaphragm and the moving coil vibrating diaphragm are respectively disposed at two ends of the acoustic transmitting member. | 06-19-2014 |
20140153766 | EARPHONE SINGLE-SHAFT STRUCTURE - An earphone single-shaft structure includes a head strip, a cap body, and a single-shaft component. The single-shaft component is located at a housing of the cap body and connected to the head strip. The single-shaft component includes a body, a rotating shaft, a shaft hole, a pivot area and swinging areas. When the head strip rotates for a first angle about the pivot area, two ends of the head strip are located on one side of each swinging area, so that the cap body rotates in a first direction, and when the head strip rotates for a second angle about the pivot area, the two ends of the head strip are located on the other side of each swinging area, so that the cap body rotates in a second direction. | 06-05-2014 |
20140140562 | EARPHONE WINDING STRUCTURE - An earphone winding structure includes: a first cap, a second cap, a connection portion, a signal line and a winding component. The winding component is located at the first cap, and includes a body, a shaft and a housing. The housing is connected to the shaft and bent into an opening state or a closing state with the shaft as the center. When the housing is bent into the opening state, the shaft is exposed and is used for winding the signal line, and when the housing is bent into the closing state, the housing covers the body and the signal line. | 05-22-2014 |
20140138150 | EARPHONE CABLE STRUCTURE - An earphone cable structure includes a first connection sleeve, a primary cable, a first branch cable, a second branch cable and a thin-type bridging section. The first connection sleeve includes a first end and a second end. The primary cable is connected to the first end, and includes first core lines and second core lines. The first branch cable is connected to the second end, and includes third core lines connected to the first core lines. The second branch cable is connected to the second end, and includes fourth core lines connected to the second core lines. The axial cross-sectional width of the primary cable is equal to the axial cross-sectional width of the first branch cable plus that of the second branch cable. The thin-type bridging section is connected between the first branch cable and the second branch cable. | 05-22-2014 |
20100046783 | Dual-frequency coaxial earphones with shared magnet - A dual-frequency coaxial earphone has a shared magnet, which is interposed between a top board of a outer yoke and an outer disk of a inner yoke, wherein the outer yoke and the inner yoke each has a different polarity. A low-frequency voice coil of a low-frequency speaker part extends axially into and between an annular wall of the outer yoke and the outer disk of the inner yoke. An inner sleeve of the inner yoke extends into a first central opening of the outer yoke. Therefore, a high frequency of the high-frequency speaker part can pass through the inner sleeve so as to energize a central diaphragm of the low-frequency speaker part and to form a same phase as, and to output frequency synchronously with, the low-frequency speaker part. As such, the problem of intermodulation of distortion for the high and low acoustic frequencies can be solved, and that dimension of the earphone can be minimized. | 02-25-2010 |
20090279729 | Dual-frequency coaxial earphones - A dual-frequency coaxial earphone includes a frame, a shared yoke, a high frequency speaker part, and a low frequency speaker part. The high frequency speaker part and the low frequency speaker part are coaxially arranged at inside and outside of the shared yoke, and are coaxial with a central opening of the frame. Further, a permanent magnet of the higher frequency speaker part is contrary, in polarity, to an annular magnet of the low frequency speaker part. Therefore, acoustic frequency of the low frequency speaker part can be phase-countered by passing thereof through an acoustic annular recess, so that the acoustic frequency of the low frequency speaker part has the same phase as the acoustic frequency of the high frequency speaker part and both then are output synchronally. The high frequency speaker part and the low frequency speaker part can then be separated, in acoustic frequency, from each other. This will effectively solve the problem of intermodulation of distortion for the high and low acoustic frequencies, and reduce the size of the earphone to more compact. | 11-12-2009 |
20090092275 | MULTIPLE SPEAKERS - A multiple speakers, including: A sound box has a long flat body and a long first voice face at front. Both sides of the first voice face incline separately to from a second voice face. A first speaker unit places inside the sound box including a left speaker and a right speaker that is placed separately at the left end and right end of the first voice face. A second speaker unit places inside the sound box including a left speaker and a right speaker that is placed separately at the left side and right side of the second voice face. | 04-09-2009 |
