A diaphragm has a configuration including a diaphragm main body, a cone part on an outer periphery of the diaphragm main body, a ring member joined to the cone part, and an edge having an inner periphery joined to an outer periphery of the ring member or an outer periphery of the cone part. This configuration improves the rigidity without changing the shape of the diaphragm main body, that is, without giving rise to a mass increase in the diaphragm main body, and keeps the sound pressure from decreasing in a high frequency range.

Provided is a headset that, by measuring earwax adhered to the headset and reporting to the user, enables prevention of earwax-induced degradation of acoustic characteristics, thereby suppressing product defects. This headset has: a headset body H; and an operating unit 6 for shifting to an earwax measurement mode. A reception unit 7 receives a measurement signal for measuring the presence or absence of earwax. A storage unit 8 saves an initial-mode measurement signal. An analysis unit 9 analyzes a characteristic which the earwax imparts to the measurement signal by comparing the initial-mode measurement signal with an earwax-mode measurement signal. A reporting unit 10 performs predetermined reporting on the basis of the results of the analysis by the analysis unit 9.
