Precautions for use of Sound Components

Please take a look for technical guideline and failure mode information before using products.

SMD Piezoelectric Sounders

No. Item Guideline
1 After Mounting

Avoid having the piezoelectric sounder in any area where foreign objects will be blown away using compressed air.

Unstable sound may occur due to deformation of the piezoelectric diaphragm and destruction of the silicone, etc.

Detail
2 Other

Do not use this product in an atmosphere containing chlorine gas, sulfidizing gas, acid, or another corrosive substances.

This may cause the characteristics of the product to deteriorate, and also reduce the sound volume level or prevent the emission of any sound at all.

Pin type Piezoelectric Sounders

 No. Item Guideline  
1 Pre-Mounting

When inserting this product manually into the printed circuit board, be careful that the pins properly enter the holes in the board.

If the fixing part of a pin is broken, it is conceivable that an open circuit may occur. Because of this sound may fail to be emitted due to the pins being pushed into the product.

Detail
2

Secure the rear cover pins to the board.Failure to do this may result in a chattering type noise.

Failure to do this may result in a chattering type noise.

Detail
3

To prevent flux vapor from entering the product, arrange the holes in the board so that they do not align with the open holes in the product.

An insulating layer is formed at the terminal contact part, which may prevent the generation of noise.

Detail
4 Soldering

It is possible for the product to become damaged from heat when being soldered. For this reason, please use a one-sided board.

If you use a two-sided through-hole board instead of a one-sided board, the rear cover or the fixing points of the pins are likely to become deformed,resulting in poor contact or an open circuit, which in turn may result in reduced sound volume or no sound at all.

5

Please review our stipulated soldering conditions (*).

If the peripheral support condition of the vibration plate changes, the sound pressure level may decrease.

Detail
6 After Mounting

If the product is tilted when soldered, melt the solder again and correct the tilt. (Do not press down on the product from the top.)

If the pins touch two locations on the piezoelectric vibration plate, a short may occur, preventing any sound from being emitted.

Detail
7

Avoid having the piezoelectric sounder in any area where foreign objects will be blown away using compressed air.

This may cause deformation of the piezoelectric sounder or cracking of the piezoelectric ceramic, resulting in unstable sound.

Detail
8

If the casing and the rear cover are separated after the product has been mounted, do not attempt to re-assemble the product. Replace it with a new one.

Deformation and mis-positioning of the pins or the vibration plate may result in unstable sound or prevent the generation of any sound at all.

Detail
9 Other

Do not insert foreign objects into the sound emission hole.

This may cause deformation of the piezoelectric sounder or cracking of the piezoelectric ceramic, resulting in unstable sound.

Detail
10

Do not use this product in an atmosphere containing chlorine gas, sulfidizing gas, acid, or another corrosive substances.

This may cause the characteristics of the product to deteriorate, and also reduce the sound volume level or prevent the emission of any sound at all.

Piezoelectric Buzzers

 No. Item Guideline  
1 Pre-Mounting

When inserting this product manually into the printed circuit board, be careful that the pins properly enter the holes in the board.

If the fixing part of a pin is broken, it is conceivable that an open circuit may occur. Because of this sound may fail to be emitted due to the pins being pushed into the product.

3

Avoid having the piezoelectric buzzer in any area where foreign objects will be blown away using compressed air.

This may cause deformation of the piezoelectric buzzer or cracking of the piezoelectric ceramic, resulting in unstable sound.

4

If the casing and the rear cover are separated after the product has been mounted, do not attempt to re-assemble the product. Replace it with a new one.

Deformation and mis-positioning of the pins or the vibration plate may result in unstable sound or prevent the generation of any sound at all.

Detail
5 Other

Do not insert foreign objects into the sound emission hole.

This may cause deformation of the piezoelectric sounder or cracking of the piezoelectric ceramic, resulting in unstable sound.

Detail
6

Do not use this product in an atmosphere containing chlorine gas, sulfurizing gas, acid, or another corrosive substances.

This may cause the characteristics of the product to deteriorate, and also reduce the sound volume level or prevent the emission of any sound at all.

Piezoelectric Diaphragms

 No. Item Guideline  
1 Pre-Mounting

Do not pull on a lead wire or handle it in such a way that it becomes bent.

The lead wire may separate from the soldering point or become an open circuit, which would prevent sound from being emitted.

Detail
2 Other

Do not use this product in an atmosphere containing chlorine gas, sulfurizing gas, acid, or another corrosive substances.

This may cause the characteristics of the product to deteriorate, and also reduce the sound volume level or prevent the emission of any sound at all.
