摘要： In an electrodynamic speaker comprising a vibrating plate, a voice coil secured to the vibrating plate, a magnetic circuit portion having a soft magnetic member and a magnet and having a magnetic gap, a frame for supporting the peripheral portion of the vibrating plate and the magnetic circuit portion, and a lead substrate. The voice coil is secured to the vibrating plate after the vibrating plate is secured to the frame and then the magnetic circuit portion is assembled on the frame. As a result of it, the lead terminal of the voice coil can be connected to the lead substrate through the notch portion of the frame in the same process as mounting the voice coil on the vibrating plate wherey the factor of variation in the magnetic gap dimension which affects the efficiency of the magnetic circuit is reduced.

摘要： An armored cord has flexibility and tensile strength for securing a telephone handset to a telephone housing. The cord includes an outer armored sheath which is designed for increased flexibility in that it allows the cord to bend readily over small radii. Tensile strength between the handset and housing is provided by an internal cable which absorbs the stress applied to the cord when subjected to unusually large longitudinal forces. The service life of the cord is lengthened, and the number of incidents causing out-of-service conditions is thereby reduced.

摘要： A loudspeaker holder including a baffle plate and a loudspeaker supported by the baffle plate is rotatably coupled to a portable sound reproducing device having an operating surface and an audio-amplifier for supplying a power output signal to the loudspeaker through a pin and opening coupling means. To utilize the loudspeaker, the loudspeaker holder is rotated about the pin to form a space between the baffle plate and the operating surface. The sounds generated by the loudspeaker are transmitted to the outside through the space and an opening provided in the baffle plate. In case of carrying the portable sound reproducing device, loudspeaker holder is rotated about the pin to bring the baffle plate into contact with the operating surface, and to extinguish the space.

摘要： A two-piece speaker assembly has a speaker base for permanent attachment to a cabinet and a detachable cone unit that may be removably attached to the base and replaced by a larger or smaller capacity speaker as desired. The separable base and cone units are threaded or provided with a bayonet-type of interlocking arrangement and biased with a spring to maintain a locked connection. Also, an electrical connection between the base and speaker cone is provided by a suitably-sized, contact-type of spring-biased terminals.

摘要： 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.
摘要翻译：一种无焊接连接器，用于将扬声器的音圈连接到位于扬声器框架上的电输入端子的柔性电动移动引线。连接器提供柔性导体和端子之间的电气连续性，并且在不需要焊料或其它机械装置的情况下机械地固定柔性导体，从而通过消除由于焊接操作中的差的工艺而导致的组装效率和提高质量。这些可动引线被称为尾纤，其长度被调节以确保长寿命并消除变形。太短的辫子将通过绷紧并将失真引入声学输出来限制锥体偏移。短辫子也会导致扬声器由于过度的应力而早期失效。太长的辫子也会由于产生杂散噪声而引起畸变。确保猪尾长度的方法采用敷料夹具。
