1. A sleeping state measurement system comprising:
a breathing sound measurement device; and
a terminal device comprising one or more of a smartphone and a tablet computer,
the breathing sound measurement device comprising:
a measurement section configured to acquire breathing sound of a subject with a contact section brought into contact with a skin of a front neck of the subject, wherein the measurement section includes a first substrate to which a microphone is attached;
a wearing section extending in a circular arc shape along an outer circumference of a subject's neck to a rear neck opposite the front neck of the subject;
a hinge section that couples a base end of the measurement section and a base end of the wearing section to each other; and
a vibrator configured to impart vibration to the subject's neck,
wherein the hinge section includes: a rotating shaft portion configured to circumferentially rotatably support the measurement section and the wearing section; and a biasing portion configured to bias the measurement section and the wearing section in a closing direction so that the subject's neck is held from outside when the breathing sound measurement device is worn on the subject's neck,
the terminal device includes: a communication module configured to communicate with the breathing sound measurement device; and a display screen,
the terminal device receives a measurement result from the breathing sound measurement device and displays information on the subject's snoring period, normal breathing period, and apneic period in at least either graph or numerical form on the display screen on the basis of the measurement result thus received, and
the terminal device displays, on the display screen, a juxtaposition of first sleep information including information on the subject's snoring period, normal breathing period, and apneic period in a vibration mode in which the vibrator is caused to vibrate and second sleep information including information on the subject's snoring period, normal breathing period, and apneic period in a non-vibration mode in which the vibrator is prohibited from vibrating.
