Singer’s Briefcase-Like Audio Study Mate is a Forgotten Multimedia Marvel from the 1970s

Singer made their name by creating sewing machines that would last for generations. However, in the 1970s, the company began to expand into unexpected areas, such as educational tools. As a result, a sturdy briefcase that resembled a carrying case for their portable sewing machines began appearing in stores. Customers were frequently surprised to open one thinking to find sewing needles and thread, only to discover something quite unexpected inside…the Audio Study Mate, a comprehensive system for mixing audio and visuals in perfect sync.

Singer created this little (relatively speaking) machine for classrooms and home study, back when lectures frequently incorporated both sound as well as still graphics. Its portable setup fits everything you need into a package that weighs less than many modern computers while yet providing a complete presentation experience.

At the center of it all is a built-in cassette tape player. Standard audio cassettes just pop in, just like they would in an era-appropriate home stereo. The player handles narrative, music, and directions with crystal-clear sound from an internal speaker. There are volume and tone controls for quick adjustments, as well as a headphone jack for privacy. The filmstrip viewer is located right next to the tape player, while a strong light shines through a loaded 35mm filmstrip, projecting onto a frosted glass screen incorporated into the lid. The optics have a focus adjuster to ensure a clean and sharp image, which is viewable in normal room lighting. The filmstrip progresses manually with a single button press, allowing you to take your time.

One of Singer’s innovative features is a synchronization system. You see, educational cassettes of the time frequently contained inaudible tone signals alongside the audio. When you play back the tape in automatic mode, these tones activate a small electromechanical mechanism that advances the filmstrip exactly one frame. As a result, the narration matches the image precisely, and static slides are transformed into a guided display without the need for you to constantly hit buttons.

Loading it is simple: insert a cassette, thread the filmstrip through the guides, close the lid, and press the play button. Manual mode is useful for practice or review, while automatic mode is ideal for when you have a class planned out. The power comes from a conventional wall outlet, so there are no batteries to worry about.

Schools ate these things up at the time, as teachers used filmstrips to teach history, physics, and languages, combining verbal explanations with decent graphics. There were other systems available, such as GE’s Show’N’Tell, which used records instead of cassettes and was aimed at children. Singer’s cassette-based version was more user-friendly and portable.

Decades later, some used examples can still function with a little TLC. The auto-advance solenoid can become stuck over time, but a careful breakdown usually resolves the issue. Filmstrips and blank cassettes are still available, allowing you to make your own material today. Singer finally moved on from this and returned to focused on sewing. The Audio Study Mate serves as a memory of a time when businesses were eager to attempt anything. On the exterior, it appears to be a standard briefcase, but within it contains a smart combination of audio and pictures that truly brought teachings to life in ways that conventional books or records could not.
