A solderless connector for joining the flexible electrical moving leads connecting the voice coil of a loudspeaker to the electrical input terminals located on the loudspeaker frame. The connector supplies electrical continuity between the flexible conductor and the terminal, and mechanically secures the flexible conductor without the need for solder or other mechanical means, thereby improving efficiency of assembly and improving quality by eliminating problems attributable to poor workmanship in soldering operations. These movable leads are known as pigtails, and their length is adjusted to insure long life and to eliminate distortion. A pigtail that is too short will limit cone excursion by becoming taut and introduce distortion into the acoustical output. A short pigtail will also result in early failure of the loudspeaker due to the excessive stress. A pigtail that is too long will also introduce distortion due to the generation of spurious noise. The method of ensuring correct pigtail length employs a dressing fixture.
A moving coil loudspeaker having a solderless electrical connector assembly, wherein said connector comprises:
A moving coil loudspeaker having an electrically nonconducting molded plastic frame, flexible electrical moving leads connecting the electrical input terminals to the moving voice coil, and a solderless electrical connector secured to said loudspeaker comprising:
A method for adjusting the length and for securing the flexible moving electrical input leads of a moving coil loudspeaker which are joined at one end to fixed locations on the diaphragm of the speaker in order to be connected to a signal power source for energizing the voice coil comprising:
