Title (EN) AUDIO DATA TRANSMISSION DEVICE
(FR) DISPOSITIF DE TRANSMISSION SONORE DE DONNEES
Abstract: front page image
(EN)An audio data transmission device, (ADT), for transmitting binary coded audio tones (1) over a telephone system, (TC). The audio data transmission device (ADT) is adapted to be utilized with a handheld, data collection terminal (DCT) provided with a speaker (12) emitting binary coded audio tones. The transmission device (ADT) consists of a muff (11) for receiving the microphone portion of a conventional telephone handpiece (T) and a solid transmission element (18). The transmission element (18) is adapted to be mechanically connected to the housing for the terminal (DCT) for channeling the data tones to the telephone handset without dampening. The transmission element (18) is defined to be mechanically tuned to the characteristics of the telephone microphone to minimize the generation of second harmonics of the desired audio tones.
(FR)Dispositif de transmission sonore de donnees, (ADT), servant a transmettre des tonalites acoustiques codees binaires (1) au moyen d'un systeme telephonique, (TC). Le dispositif de transmission sonore de donnees (ADT) est adapte a l'utilisation d'un terminal de poche de saisie de donnees (DCT) pourvu d'un haut parleur (12) emettant des tonalites acoustiques codees binaires. Le dispositif de transmission (ADT) se compose d'un manchon (11) servant a recevoir la partie microphone d'un combine telephonique conventionnel (T) et d'un element (18) solide de transmission. L'element de transmission (18) est concu de maniere a pouvoir etre connecte mecaniquement au boitier du terminal (DCT) et diriger les tonalites acoustiques vers le combine telephonique sans les attenuer. L'element de transmission (18) est defini de maniere a etre accorde mecaniquement aux caracteristiques du microphone du combine telephonique pour reduire au minimum la production de deuxiemes harmoniques des tonalites acoustiques desirees.
