Piezo Ceramic Wafer Plate Dia 27mm For Buzzer Loudspeaker generator

Description

A Piezo Ceramic Wafer Plate with a diameter of 27mm is a small, circular ceramic component used in various electronic devices, particularly in applications involving sound generation, such as buzzers and loudspeakers. Here’s a description of its key features and uses:

**1. Piezoelectric Ceramic:** This wafer plate is made of piezoelectric ceramic material. Piezoelectric materials can generate electrical charges when mechanical stress is applied to them and, conversely, they can produce mechanical vibrations when an electrical voltage is applied. This property makes them ideal for sound generation and detection.

**2. 27mm Diameter:** The wafer plate has a circular shape with a diameter of 27mm, which is relatively small and suitable for compact and portable devices.

**3. Sound Generation:** Piezo ceramic wafers are commonly used in buzzers, sirens, and other sound-producing devices. When an electrical voltage is applied to the ceramic plate, it vibrates, producing sound waves. These wafers are known for their high-pitched and loud sound output.

**4. Loudspeaker Applications:** In addition to buzzers, piezo ceramic wafers can be used in loudspeakers and miniature audio devices, particularly in situations where space is limited.

**5. Versatile Use:** Piezo ceramic wafers are versatile components and can be employed in a wide range of applications beyond sound generation, including ultrasonic sensors, pressure sensors, and as actuators in various electronic systems.

**6. Resonant Frequency:** Each piezo ceramic wafer has a specific resonant frequency, which is the frequency at which it vibrates most efficiently. This frequency can be influenced by the size and thickness of the ceramic, as well as the mechanical mounting. It’s important to operate the wafer within its resonant frequency range for optimal performance.

**7. Robust and Durable:** Piezo ceramic wafers are known for their robustness and durability. They can withstand mechanical stress, making them suitable for applications where reliability is critical.

**8. Voltage Requirements:** The wafers typically require a specific voltage to produce sound. The sound intensity can be controlled by varying the applied voltage.

**9. Low Power Consumption:** Piezo ceramic wafers are energy-efficient and have low power consumption, making them suitable for battery-powered devices.

**10. Mounting:** Proper mounting and mechanical coupling are essential for optimizing the performance of these wafers. The way the wafer is mounted can affect its vibration characteristics and sound output.

In summary, a Piezo Ceramic Wafer Plate with a diameter of 27mm is a versatile component used for sound generation in devices like buzzers, loudspeakers, and other audio-related applications. Its piezoelectric properties make it a valuable tool for generating sound efficiently, and it can be used in a variety of electronic and acoustic projects.
