## **Notice (Driving)** 

1. When using a piezoelectric buzzer, there is no need to prepare the oscillation circuit; it has an oscillation circuit. 

2. 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 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 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.

## Design Procedure · Drive Method 

## **Design Procedure** 

In general, man’s audible frequency range is about 20Hz to 20kHz. 

Frequency ranges of 2kHz to 4kHz are most easily heard. 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. 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). Since the piezoelectric diaphragm and cavity have proper resonant frequencies, (fo) and (fcav) respectively, sound pressure in specific frequencies can be increased and a specific bandwidth can be provided by controlling both positions.

## **Drive Method** 

This method produces sound by driving the piezoelectric diaphragm with electric signals supplied from an external oscillating circuit such as a multivibrator.

External<br>Drive Circuit<br>**----- End of picture text -----**<br>


Using this method, the piezoelectric buzzer can work as a speaker. In this method, a mechanical oscillation Qm of the piezoelectric diaphragm is damped properly to provide a wider frequency band of the sound pressure. This is applied 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. Fig. 3 shows examples of the circuit to which the external drive method is applied: ( i ) represents a circuit driven by output signals of the unstable multivibrator; ( ii ) represents a circuit using 2 NAND gates, which is oscillated or stopped by ON/OFF operations of the input signal; ( iii ) represents a circuit driven by output signals of CMOS LSI.

## **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.). 

A piezoelectric ceramic plate is attached to a metal plate with adhesives. Fig. 2 shows the oscillating system of a piezoelectric diaphragm. 

Applying DC voltage between electrodes of a piezoelectric diaphragm causes mechanical distortion due to the piezoelectric effect. For a misshapen piezoelectric element, 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 bonded to the piezoelectric element does not expand. Conversely, when the piezoelectric element shrinks, the piezoelectric diaphragm bends in the direction shown in Fig. 2 (b). Thus, when AC voltage is applied across 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.

## **To Raise Sound Pressure Level (S.P.L.)** 

It is probable that the S.P.L. of Piezoelectric sound components is higher when the input voltage is higher because Piezoelectric sound components are driven by voltage. The relationship between S.P.L. and the input voltage is basically shown in the following fomula: S.P.L. after increased input voltage(dB)= 

previous S.P.L.+20Log(V2/V1) V1: previous input voltage V2: increased input voltage 

Therefore, S.P.L. is theoretically getting 6dB higher as the input voltage is twice as high. 

Fig. 1 represents S.P.L. - frequency characteristics for PKLCS1212E4001-R1 in which the input voltage is varied. We can see that S.P.L. is approximately getting 6dB higher as the input voltage is twice as high. 

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.

## **Measuring Procedure** 

## Measurement of Resonant Frequency and Resonant Impedance 

When the piezoelectric diaphragm oscillates freely in air, the node does not move as shown in Fig. 1. With this point held with a measuring terminal, the resonant frequency (f0) and resonant impedance (R0) are measured in the constant-current circuit as shown in Fig. 2. 

## Measuring Procedure 

- 1) Connect the switch to side "a" and adjust frequency of the oscillator to read the frequency and the voltage when the voltmeter indicates a minimum value. 

- 2) Next connect the switch to side "b" and vary the variable resistor to have the same voltage as in 1). Then, read the value of the resistor. 

- 3) The resonant frequency (f0) can be obtained from 1) and the resonant impedance (R0) from 2). 

Note: Actual measurement is performed using a measuring unit in accordance with the above principles. 

## Measurement of Sound Pressure Level (S.P.L.) 

The sound pressure level is measured with a sound pressure level meter as shown in Fig. 3. 

Note: The relation between sound pressure level and distance between sound pressure level and voltage can be expressed with Formula (2). The value of the sound pressure level under different operating conditions can be easily calculated using values specified in the catalog.
