摘要： A speaker with a tweeter angle adjusting device, including a woofer; a horizontal shaft supported on the woofer horizontally and rotatably; a horizontal adjusting knob disposed in parallel with and in the same rotating direction as the horizontal shaft, the horizontal adjusting knob being connected to the horizontal shaft through an interlocking mechanism; a tweeter; a tweeter housing which is secured to the horizontal shaft and which supports the tweeter through a vertical shaft rotatably in a direction perpendicular to the horizontal shaft; and a vertical adjusting knob connected to the tweeter through an interlocking mechanism to rotate in the same direction as the tweeter and journalled in a direction perpendicular to the horizontal shaft. The tweeter direction changing operation can be done easily and accurately because the tweeter shifts in the same directions as the turning directions of the horizontal and vertical adjusting knobs. Besides, since the tweeter can shift also in the transverse direction, the improvement of a high frequency range and a satisfactory stereo feeling can be attained.

摘要： PURPOSE:To obtain a speaker unit excellent in water-proof and moisture-proof in terms of both material and structure by forming a diaphragm and a voice coil bobbin by a plastics integrally and inserting a voice coil winding to the voice coil bobbin. CONSTITUTION:A cone type diaphragm 12 is formed integrally from one end of the voice coil bobbin 11 by a plastics. The voice coil 13 with winding is insert-formed to the voice coil bobbin 11 at its integral forming, both ends of the voice coil 13 are lead wires 13A of gold thread function and led to the outside from the voice coil bobbin 11 and connected to a terminal 14 provided to a speaker frame 21 via the diaphragm 12. The voice coil 13 inserted to the voice coil bobbin 11 is placed in the air gap of a magnetic circuit 22 and the inner circumferential ridge of a damper 23 of doughnut shape is fixed to one end of the voice coil bobbin 11 and the outer circumferential ridge of the damper 23 is fixed respectively to the speaker frame 21. Thus, structural water- proof is given and water-proof performance is provided also to the diaphragm 12.

摘要： PURPOSE:To make it possible to eliminate a reflecting sound from the rear glass side by installing at the opening section side of a frame a slit for exhausting sound wave to be discharged from the opening section in at least one horizontal direction. CONSTITUTION:In the opening section side of frame 2 of speaker unit 1, a grill 3a is installed, and in the grill 3a a slit 3e is installed in three horizontal directions except the rear glass side. Further, from slits 3e installed in those sections except the rear glass section, sound is radiated in three horizontal directions. In this case, since suppression is made so as to protect sound from extending to the rear glass side, reflecting sound from the rear glass side is not caused, thereby reducing a dip specially in the neighborhood of 500Hz. Therefor, regenerating clear is made possible.

摘要： PROBLEM TO BE SOLVED: To provide a speaker grill capable of preventing the decline of sound quality in an oblique direction with simple constitution, and a speaker device.
SOLUTION: The speaker device 1 has a diaphram 223 and the speaker grill 4 equipped on the front surface side of the diaphram 223, and the speaker grill 4 is provided with an opening region part 41 formed at the front surface position of the diaphram 223 for opening the entire outer diameter of the diaphram 223 in the front direction of the diaphram 223 and a shielding region part 42 formed at the side part of the opening region part 41 for shielding a part of the diaphram 223 in the oblique direction of the diaphram 223. Thus, the decline of the sound quality in the oblique direction is prevented with the simple constitution. Also, for the speaker grill 4, since the opening region part 41 is formed in the front direction, the sound quality in the front direction is not lowered.
