Speaker for Biocare FM-801 Fetal Monitor
Biocare FM-801 Fetal Monitor Loud Speaker 8Ω 3W with Connect Cable for Medical Device Replacement Part
► Brief Description
The core function of the Biocare FM-801 Fetal Monitor Loudspeaker is to "sonify" physiological signals. Its main functions include:
Playing fetal heart rate sounds: This is the most important function. The speaker converts the monitored fetal heartbeat signal into simulated "beep" sounds in real time. Each "beep" corresponds to a fetal heartbeat.
- Playing alarm sounds: When the device detects an abnormality (such as an excessively high or low fetal heart rate, or signal loss), a unique, high-priority alarm sound is emitted through the speaker to quickly attract the attention of medical staff.
- Playing operation prompt sounds: When the user presses a button, a gentle "beep" sound may be emitted to provide confirmation feedback.

► Working Principle
The Biocare FM-801 Fetal Monitor Loudspeaker is a typical electroacoustic transducer device, consisting primarily of a permanent magnet, voice coil, diaphragm, and frame. The mainboard processes the fetal heartbeat signal from the ultrasound probe, generating an audio signal synchronized with the heart rate. This audio signal is amplified and transmitted to the speaker's voice coil. The varying current in the voice coil causes it to reciprocate in the magnetic field generated by the permanent magnet. This vibration of the voice coil drives the diaphragm, which in turn pushes the surrounding air, generating sound waves, which we hear as fetal heart sounds.
► Features
1. The Biocare FM-801 Fetal Monitor Loudspeaker delivers clear, crisp sound without distortion, ensuring the distinct identification of heartbeats.
2. Appropriate Volume and Adjustability: The volume is loud enough to be heard in noisy delivery rooms or hospital rooms, yet adjustable to avoid disturbing patients' rest at night.
3. Reliability: The device must operate stably over long periods of time, and its diaphragm and other materials must be able to withstand certain temperature and humidity fluctuations.
4. Electromagnetic Compatibility: The device's internal magnets and circuitry are designed to operate without interfering with the normal operation of other components.
