Reliable sound source for physics labs The Laboratory Speaker is a classroom loudspeaker designed to convert electrical signals into sound for physics experiments. It allows students to investigate sound waves, frequency, and vibration through direct observation and measurement. Featuring a full-range speaker mounted on a durable metal base with standard lab connections, it integrates easily with signal generators and other equipment. Its wide frequency response supports a range of demonstrations—from hearing limits to interference and waveform visualization—making it a versatile tool for sound and wave investigations. The optimum audio frequency range is 80 Hz to 22 kHz, but the speaker will respond to signals well beyond this range when required. Why Teachers Love the Laboratory Speaker Clear sound output: Full-range speaker produces audible, reliable results Easy lab integration: Standard connections work with common classroom equipment Versatile demonstrations: Supports frequency, vibration, and interference experiments Durable design: Metal base stands up to repeated classroom use
