Notice (Handling)
- Do not apply DC bias to the piezoelectric buzzer; otherwise insulation resistance may become low and affect the performance.
- Do not supply any voltage higher than applicable to the piezoelectric buzzer.
- Do not use the piezoelectric buzzer outdoors. It is designed for indoor use. If the piezoelectric buzzer has to be used outdoors, provide it with waterproofing measures; it will not operate normally if subjected to moisture.
- Do not wash the piezoelectric buzzer with solvent or allow gas to enter it while washing; any solvent that enters it may stay inside a long time and damage it.
- A piezoelectric ceramic material of approximately 100µm thick is used in the sound generator of the buzzer. Do not press the sound generator through the sound release hole otherwise the ceramic material may break. Do not stack the piezoelectric buzzers without packing.
- Do not apply any mechanical force to the piezoelectric buzzer; otherwise the case may deform and result in improper operation.
- Do not place any shielding material or the like just in front of the sound release hole of the buzzer; otherwise the sound pressure may vary and result in unstable buzzer operation. Make sure that the buzzer is not affected by a standing wave or the like.
- Be sure to solder the buzzer terminal at 350°C max. (80W max.) (soldering iron tip) within 5 seconds using a solder containing silver.
- Avoid using the piezoelectric buzzer for a long time where any corrosive gas (H2S, etc.) exists; otherwise the parts or sound generator may be corroded and result in improper operation.
- Be careful not to drop the piezoelectric buzzer.
Frequently Asked Questions
Q1
What is the resonance frequency of the HYR-1708 piezoelectric buzzer?
The HYR-1708 has a resonance frequency of 4.5 KHz (±500 Hz), driven by a square wave signal. This makes it suitable for alert and notification applications requiring a clear, audible tone.
Q2
What is the maximum input voltage for the HYR-1708?
The maximum input voltage for the HYR-1708 is 16 Vp-p. Never exceed this voltage, as doing so may damage the buzzer or cause it to malfunction.
Q3
Can the HYR-1708 piezoelectric buzzer be used outdoors?
The HYR-1708 is designed for indoor use only. If outdoor use is required, adequate waterproofing measures must be applied, as exposure to moisture will prevent normal operation and may permanently damage the unit.
Q4
What are the operating and storage temperature ranges?
The HYR-1708 operates within a temperature range of -20°C to +70°C. For storage, the acceptable range is -30°C to +80°C. Operating or storing outside these ranges may compromise performance and longevity.
Q5
How should the HYR-1708 buzzer be soldered?
Solder the buzzer terminals using a soldering iron at a maximum temperature of 350°C (80W max.) within 5 seconds. It is recommended to use a solder containing silver to ensure a reliable connection without damaging the component.
Q6
What housing material is used in the HYR-1708, and what is its weight?
The HYR-1708 features a housing made of Black PBT (Polybutylene Terephthalate), a durable and heat-resistant thermoplastic. The total weight of the buzzer is approximately 0.7 grams, making it lightweight and easy to integrate into compact electronic designs.
