AUDIO COMMUNICATION

An electronic device can include a housing, a securement feature, a noise generator, a receiver, and a processor. The housing can define an internal volume. The securement feature can be connected to at least a first side and a second side of the housing and can extend between the first side and the second side. The noise generator can be connected to the securement featured and be configured to generate a sound with a frequency. The receiver can be disposed within the internal volume and be configured to receive the sound. The processor can be disposed within the internal volume and in communication with the receiver, and be configured to process the sound and perform an operation.
