    The electrical and physical parameters which are of interest in loudspeaker design are discussed. The analysis of loudspeaker action on the basis of its analogy to a vibrating rigid disk is presented. The limitations of such an analysis are indicated. Electromechanical analogies are used to formulate an equivalent electro-mechanical circuit from which loudspeaker performance factors can be derived... View full abstract»

    For more than a quarter of a century the normal broadcast receiver has been equipped with a single loudspeaker fitted inside the cabinet. The introduction of sets with two separate speakers, each reproducing part of the frequency spectrum on the Philips "Bi-Ampli" principle, dates only from the last few years. The installation described goes a big step further, the loudspeakers berg entirely separ... View full abstract»

    The amplifier descrbied in this paper has an input resistance of approximately 400,000 ohms in the audio-frequency range. The output noise level is equivalent to 5 µv at the input terminals with a response that is down 3 db at 5 cycles and at 100 kc. The amplifier has been designed in a self-contained package, the size of a frozen orange juice can suitable for plugging into the standard banan... View full abstract»
