Please set the sounding time more than 200 msec., when driving the piezoelectric sounder of self-drive or the piezoelectric buzzer as an intermittent sound. 3. Please don’t block the sound emission hole with tape to control the sound volume. The oscillation circuit condition is set so as to obtain a stable sounding (oscillating) state under the condition that the front of sound emission hole Capacitor Buzzer (1μF) is in an open state. If the sound emission hole is blocked with tape, then the oscillation condition changes and the sounds might become unstable. 4. Please don’t put a resistor between the oscillation circuit Fig. 2 and power supply to control the sound volume of the piezoelectric sounder or the piezoelectric buzzer. Doing so could cause an unstable sounding state like an abnormal oscillation or the oscillation stopping because of the change in oscillation conditions. Please insert a capacitor (about 1μF) in parallel with the piezoelectric buzzer, if you need to control the sound volume. (Please see Fig. 2) 5. Please keep a distance of more than 15mm between the surface of sound emission hole and the surface of housing, when mounting the piezoelectric sounder of self-drive or the piezoelectric buzzer into your set. A shorter distance could cause an unstable sounding state like an abnormal oscillation or the oscillation stopping; because the oscillation conditions change, the acoustics are influenced by reflection. 18

Feb.5,2018 Design Procedure · Drive Method Design Procedure In general, man’s audible frequency range is about 20Hz to 20kHz. d Frequency ranges of 2kHz to 4kHz are most easily heard. 2a R For this reason, most piezoelectric sound components are used in this frequency range and the resonant frequency (fo) is generally selected in the same range. V h In general, the piezoelectric diaphragm is installed in a cavity to produce high sound pressure (Fig 1). The resonant frequency (fcav) of the cavity in Fig. 1 is obtained from Formula (1) (Helmholtz’s Formula). fcav = C2 V (Ra+ 21.3a) = C2 d 2h (4Ra+ 21.3a) ····················· (1) Since the piezoelectric diaphragm and cavity have proper fcav : Resonant freq. of a cavity (Hz) 3 c : Speed of sound (cm/sec) resonant frequencies, (fo) and (fcav) respectively, sound Ref) approx. 347 x 102cm/sec at 25°C pressure in specific frequencies can be increased and a a : Radius of sound emitting hole (cm) d : Diameter of a supporting rim (cm) specific bandwidth can be provided by controlling both h : Depth of a cavity (cm) positions. R: Wall thickness of a cavity (cm) Fig. 1 Sectional View of a Cavity Drive Method This method produces sound by driving the piezoelectric diaphragm with electric signals supplied from an external oscillating circuit such as a multivibrator. Using this method, the piezoelectric buzzer can work as a External speaker. In this method, a mechanical oscillation Qm of the Drive Circuit piezoelectric diaphragm is damped properly to provide a wider frequency band of the sound pressure. This is applied Fig. 2 Drive Procedure to the switching sounds of home electric appliances, key-in sounds of OA equipment, because it can provide multiple sounds, not just a single sound.

Feb.5,2018 Oscillating System Basically, the sound source of a piezoelectric sound component is a piezoelectric diaphragm. A piezoelectric diaphragm consists of a piezoelectric ceramic plate that has electrodes on both sides and a metal plate (brass or stainless steel, etc.). Electrode Piezoelectric A piezoelectric ceramic plate is attached to a metal plate Piezoelectric Element with adhesives. Fig. 2 shows the oscillating system of a Electrode Ceramics Piezoelectric Diaphragm piezoelectric diaphragm. Piezoelectric Metal Applying DC voltage between electrodes of a piezoelectric Ceramics Plate diaphragm causes mechanical distortion due to the piezoelectric effect. For a misshapen piezoelectric element, Fig. 1 Structure of Piezoelectric Diaphragm the distortion of the piezoelectric element expands in a radial direction, and the piezoelectric diaphragm bends toward the direction shown in Fig. 2 (a). The metal plate (a) Extended State bonded to the piezoelectric element does not expand. Conversely, when the piezoelectric element shrinks, the (c) AC Voltage Applied piezoelectric diaphragm bends in the direction shown in Fig. 2 (b). Thus, when AC voltage is applied across (b) Shrinked State electrodes, the bending shown in Fig. 2 (a) and Fig. 2 (b) is repeated as shown in Fig. 2 (c), producing sound waves in the air.

It is probable that the S.P.L. of Piezoelectric sound components is higher when the input voltage is higher Frequency Characteristics of Sound Pressure Level PKLCS1212E4001-R1 because Piezoelectric sound components are driven by 100 ±6.0Vp-p ±3.0Vp-p voltage.

Distance: 10cm Wave form: Square Wave We can see that S.P.L. is approximately getting 6dB higher as the input voltage is twice as high. Fig. 1 Frequency Characteristics of Sound Pressure Level In summary, the following are typical examples of raising S.P.L. (1) ( i ), ( ii ), ( iii ) in Fig. 3 (Examples of the External Drive Circuit) (page 19), input DC voltage for Piezoelectric sound components should be getting higher. Variable range of input voltage should be less than maximum input voltage. (2) In a case that is driven by IC directly like as Fig. 2, input voltage of Piezoelectric sound components should be twice as high because of the BTL (Bridge Tied Load) drive circuit, which includes an inverter.
