In this way, the coil 24 is energized.
  • PWM Pulse Width Modulation
  • the control part 34 By outputting the PWM signal to the driving part 33, the control part 34 energizes the coil 24 and vibrates the diaphragm 21 at a predetermined frequency. In this case, the control part 34 changes the frequency which vibrates the diaphragm 21 according to the temperature T measured in the temperature measurement part 30.
  • the frequency at which the diaphragm 21 vibrates (referred to as “vibration frequency” hereinafter) is the frequency f out of the PWM signal.
  • a characteristic of the control part 34 is that when the temperature T measured by the temperature measurement part 30 is within the temperature range of low temperature, the control part 34 deviates the vibration frequency which vibrates the diaphragm 21 from the resonance frequency fc at which the amplitude of the diaphragm 21 is the greatest.
  • the control part 34 sets the frequency f out to the frequency f 0 which is the initial value of the frequency of PWM signals.
  • the frequency f 0 is the resonance frequency fc in the normal temperature range.
  • the control part 34 sets the frequency f out to a value (fo-fx) obtained by subtracting a predetermined frequency fx from the frequency f 0 .
  • the control part 34 inhibits the amplitude of the diaphragm 21 by deviating the vibration frequency from the resonance frequency fc. Accordingly, the control part 34 can prevent the collision of the movable iron core 22 and the fixed iron core 23, and can prevent the production of abnormal noise.
  • control part 34 changes the frequency which vibrates the diaphragm 21 according to the voltage value Vb measured by the voltage measurement part 31.
  • a characteristic of the control part 34 is that when the voltage value Vb measured by the voltage measurement part 31 is within a voltage range of high voltage, the control part 34 deviates the vibration frequency which vibrates the diaphragm 21 from the resonance frequency fc.
  • the control part 34 sets the frequency f out to the frequency f 0 which is the initial value of the frequency of PWM signals.
  • the control part 34 sets the frequency f out to a value (f 0 -fx) obtained by subtracting the predetermined frequency fx from the frequency f 0 .
  • the control part 34 inhibits the amplitude of the diaphragm 21 by deviating the vibration frequency from the resonance frequency fc. Accordingly, the control part 34 can prevent the collision of the movable iron core 22 and the fixed iron core 23, and can prevent the production of abnormal noise. Moreover, when the current value flowing through the coil 24 increases because the ambient temperature (for example, the temperature T) of the horn device A becomes a low temperature, the control part 34 may also prevent the amplitude of the diaphragm 21 be deviating the vibration frequency from the resonance frequency fc.
  • the control part 34 sets the frequency f out to the frequency f 0 which is the initial value. Besides, the control part 34 sets the duty ratio D out to the duty ratio Do which is the initial value (step S101).
  • the control part 34 when a warning signal is obtained from outside, the control part 34 generates PWM signals of the set frequency f out and duty ratio D out , and outputs the generated PWM signals to the driving part 33. In this way, the control part 34 energizes the coil 24 and vibrates the diaphragm 21 at the frequency f 0 , by which sound is produced from the sound outlet 12 of the resonator 1 to outside.
  • the control part 34 obtains the temperature T from the temperature measurement part 30 (step S102).
  • the control part 34 determines whether the obtained temperature T is within the temperature range of low temperature (step S103). For example, when the obtained temperature T is determined to be lower than the first temperature threshold T th1 , the control part 34 determines that the obtained temperature T is within the temperature range of low temperature. On the other hand, when the obtained temperature T is determined to be higher than the first the temperature threshold T th1 , the control part 34 determines that the temperature T is not within the temperature range of low temperature.
  • the first the temperature threshold T th1 is set according to the temperature of the coil 24 when the current value, which is capable of producing the attraction force that collides the fixed iron core with the movable iron core when PWM signals are output to the coil 24, flows through the coil 24.
  • control part 34 obtains the voltage value Vb from the voltage measurement part 31 (step S104).
  • the control part 34 determines whether the obtained voltage value Vb from the voltage measurement part 31 is within the voltage range of high voltage (step S105). For example, when the obtained voltage value Vb is determined to be higher than the second voltage threshold V th2 , the control part 34 determines that the obtained voltage value Vb is within the voltage range of high voltage. On the other hand, when the obtained voltage value Vb is lower than the second voltage threshold V th2 , the control part 34 determines that the voltage value Vb is not within the voltage range of high voltage.
  • the second voltage threshold V th2 is set according to the voltage applied to the coil 24 or the output voltage of the power supply device 32 when the current value, which is capable of producing the attraction force that collides the fixed iron core with the movable iron core in the electromagnet, flows through the coil 24.
  • the control part 34 sets the frequency f out which is approximately equal to the resonance frequency fc to the frequency f 0 (step S106).
  • the control part 34 sets the frequency f out to the value (fo-fx) obtained by subtracting the predetermined frequency fx from the frequency f 0 (step S107). Accordingly, when the voltage value Vb is determined to be within the voltage range of high voltage, the control part 34 can inhibit the amplitude of the diaphragm 21 by deviating the vibration frequency from the resonance frequency fc and prevent abnormal noise.
  • the resonance frequency fc becomes high.
  • step S108 when the obtained temperature T is determined to be within the temperature range of low temperature, the control part 34 sets the frequency f out to the value (f 0 -fx) obtained by subtracting the predetermined frequency fx from the frequency f 0 (step S108). Accordingly, when the temperature T is determined to be within the temperature range of low temperature, the control part 34 can inhibit the amplitude of the diaphragm 21 and prevent abnormal noise by deviating the vibration frequency from the resonance frequency fc. In addition, when the frequency property of the diaphragm 21 at room temperature shown in Fig. 6(a) is compared with the frequency property of the diaphragm 21 at low temperature shown Fig. 6(b) , the resonance frequency fc at low temperature is higher than the resonance frequency fc at room temperature.
  • the horn device A is characterized in deviating the vibration frequency which vibrates the diaphragm 21 from the resonance frequency fc according to at least any of the temperature T measured by the temperature measurement part 30 and the voltage value Vb measured by the voltage measurement part 31. Accordingly, the horn device A can prevent the production of abnormal noise caused by the collision of the fixed iron core 23 and the movable iron core 22 due to the increase of attraction force of the electromagnet.
  • the control part 34 of the horn device A reduces the vibration frequency (f out ) which vibrates the diaphragm 21 for only a predetermined value fx.
  • the control part 34 of the aforementioned embodiment may also be realized by a computer.
  • a program used to realize the function may be recorded in a computer-readable recording medium, and the function may be realized by making a computer system read in the program recorded in the recording medium and implementing the program.
  • the "computer system” mentioned here includes a hardware such as OS or peripheral device.
  • the "computer-readable recording medium” is a memory device such as a movable medium like a flexible disk, a magnetic optical disk, a ROM and a CD-ROM, and a built-in hard disk in the computer system.
  • computer-readable recording medium means a recording medium which dynamically keeps programs for a short time like a communication wire that transmits programs via a network such as the Internet or via a communication line such as a telephone line, including a recording medium which keeps programs for a specific time like a volatile memory within the computer system which becomes a server or client in this situation.
  • the programs may be programs which are used to realize a part of the functions, may be programs realized by a further combination with programs which already record the functions in the computer system, or may be programs which are realized by using programmable logic arrays such as a FPGA (Field Programmable Gate Array).
