Chestbox

Chestbox is a generic term for a portable hardware enclosure worn on the chest to house electronics and power sources. The box typically attaches to clothing via straps or a harness and serves as a container for a transmitter, sensor module, or data logger that must be carried close to the body for wireless communication, monitoring, or signal acquisition.

In telecommunications and audio, chest boxes are commonly used as body-worn transmitters or receivers in wireless microphone systems, intercoms, or field radios. A microphone or instrument feed is routed to the chest box, which provides amplification, modulation, and battery power before transmitting to a receiver elsewhere.

In medical contexts, chest-mounted boxes are used for ambulatory monitoring and telemetry. Examples include Holter monitors and event recorders, which collect physiological signals such as electrocardiograms and then transmit or store data for later analysis.

Design considerations include ergonomics, weight, weather resistance, battery life, durability, and secure attachment. Modern chest boxes may integrate Bluetooth, USB, or RF links, and are designed to minimize movement artifact and discomfort during extended wear.

Owing to its broad applicability, the term chestbox can refer to different devices across industries. When encountered, the precise function is determined by the user community and context (for example, audio production, medical monitoring, or field communications).
