The determination processor 24 determines that an event associated with generation of the impulse sound (first target sound) occurs at the time t3. In contrast, when the sound signal does not reach or exceed the threshold Th1 within the determination time T1, the determination processor 24 determines that no event associated with generation of the impulse sound (first target sound) occurs. Thus, it is possible to reduce erroneous determinations of whether or not an event associated with generation of the impulse sound (first target sound) as a detection target occurs when the impulse sound is generated once.

  • the determination processor 24 is configured not to detect the impulse sound (second target sound) when the time interval of the impulse sound (second target sound) is shorter than a predetermined time (e.g., 200 ms).
  • the determination processor 24 detects the impulse sound (second target sound) at times t11, t12, tl3, and t14, and the count value of the counter 242 is four (that is, a plurality of number of times), and therefore, the determination processor 24 determines that an event associated with generation of the impulse sound (second target sound) occurs. In contrast, when the impulse sound (second target sound) is detected once within the specified time T2, the determination processor 24 determines that no event associated with generation of the impulse sound (second target sound) occurs.

  • the determination processor 24 associates the number of times the impulse sound (second target sound) is detected within the specified time T2 with contents of an event. For example, when the determination processor 24 detects an impulse sound (second target sound) generated by clapping hands two times within the specified time T2, the determination processor 24 determines that an event of clapping hands two times occurs.
  • the determination processor 24 may be configured to measure the time interval between impulse sounds (second target sounds). When the impulse sound (second target sound) is generated a predetermined number of times at a predetermined time interval, the determination processor 24 determines that an event involving generation of the impulse sound (second target sound) occurs. For example, when the determination processor 24 detects the impulse sound (second target sound) generated by clapping hands three times at a time interval of 0.5 seconds to 1 second and detects no impulse sound (second target sound) during a period of one second after detection of the third impulse sound (second target sound), the determination processor 24 determines that an event of clapping hands three times occurs. Moreover, when the determination processor 24 detects an impulse sound (second target sound) generated at a prescribed rhythm, the determination processor 24 determines that an event of clapping hands at a prescribed rhythm occurs.

  • the frequency characteristics of a sound of clapping hands are different depending on a way of clapping the hands, the size of the hands (a volume of air between the hands), and the like.
  • the difference between the frequency characteristics leads to a large difference in, in particular, a low-frequency range.

  • the sound pressure level determination processor is configured to determine, based on a sound signal generated by the sound collector 22, whether or not the sound pressure level of the sound collected by the sound collector 22 is higher than or equal to a threshold.
  • the filter 28 removes, based on a determination result by the sound pressure level determination processor, a low-frequency component from only a sound signal obtained by converting a sound having sound pressure level higher than or equal to the threshold.

  • the sound collector 22 can efficiently collect a sound around the plug connector 1 because sound insulation by the attachment plug 41 is suppressed.
  • the plug connector 1 can easily realize the function as a security sensor by only connecting the attachment plug 11 to the plug receptacle 31 of the socket 3. Moreover, the difference between the appearance of the plug connector 1 and the appearance of a plug connector having only a function as wiring accessories is small. Therefore, an invader is less likely to notice that the plug connector 1 also serves as a security sensor, which suppresses detachment of the plug connector 1 by the invader.
  • the plug connector 1 is capable of serving as a security sensor or a remote controller without being manually operated by a user. Therefore, it is possible to suppress a reduction in convenience due to installation at a location where an operation is hardly performed. Moreover, installing the plug connector 1 at a location where the plug connector 1 is hardly noticed by an invader reduces the probability that the invader notices and detaches the plug connector 1.
  • the target sound as the detection target of the determination processor 24 is the impulse sound
  • the target sound is not limited to the impulse sound but may be a sound other than the impulse sound.
