Abstract

PURPOSE:To always execute annunciation without fail regardless of a surrounding noise by providing a sound gathering means to pick up the surrounding noise with signal reception, a storing means to store a noise level to be gathered by this sound gathering means and a speaker means to output an announcing tone in correspondence to the level which is stored by this storing means. CONSTITUTION:An annunciating device is equipped with a sound gathering means 5 to pick up the surrounding noise by the signal reception, a storing means 4 to store the level of the noise, which is gathered by this sound gathering means 5, and a speaker means 6 to output the annunciating tone of volume to correspond to the level which is stored by this storing means 4. Accordingly, since the size of a warning tone, which is generated from a warning device, always generates the tone of the large level which is constant from a surrounding tone, an influence due to the surrounding noise is not received. Thus, a regardless of the surrounding noise, the annunciation can be always executed without fail.

る。In such a notification device, when a sensor active signal enters the receiving unit (2), the CPU of the warning device (1)
(3) instructs the sound level meter (5) to collect ambient sound and convert it into dB (decibels). The sound level meter (5) is CPU (
3), the microphone (11) picks up surrounding sounds for a certain period of time, and the output voltage from this microphone (11+) is given to the frequency correction circuit (13) via the preamplifier (12). Correction circuit (13)
Then, the volume level of each frequency is corrected and output according to the human hearing sensitivity characteristics, and the output signal is amplified by an amplifier (14), integrated by an integrating circuit (15), and then sent to a leveling circuit (16).
) is converted into a decibel value and sent to the CPU (3). After storing this decibel value in the memory (4), the CPU (3) transmits a 9-alarm tone signal to the speaker (6), and the speaker (6) generates an alarm tone to the outside. Thereafter, the CPU (31) instructs the sound level meter (5) to collect ambient sound and calculate dBm, and receives a dB unit conversion signal from the sound level meter (5) in the same manner as before.C
At P U (3), a value obtained by adding a constant value to the reference level from the memory (4) is compared with the received signal. By comparison, if the current decibel value is large, lower the volume of the alarm sound (
26) The CPU (3) of the sea urchin alarm system works and increases the volume of the alarm sound when the current decibel value is small (2
7). Thereafter, the CPU (3) receives a signal from the security sensor indicating that it has become "non-active" via the sensor signal receiving section (2), and the alarm sound from the speaker (6) continues until the command to stop the alarm is issued. Continuing.As described above, the loudness of the alarm sound generated by the alarm device is always a certain level louder than the surrounding sounds, so it is not affected by surrounding noise. FIG. 2 is a block diagram of the sound level meter, and FIG. 3 is a flowchart showing the operation of the notification device of the present invention.
