Piezo Transducer
The dictionary definition for a transducer is “any device that converts one form of energy into another”. It has a very broad meaning and encompasses electric motors, microphones, speakers and buzzers for example.
Audio transducer definition:
What is the difference between a piezo transducer and an electro mechanical transducer?

This varies considerably between products. Typically, the larger the sounder the higher the sound output. One of our smallest buzzers, the ABT-460-RC is only 6.5mm diameter and 3.6mm high. It’s sound output is 70dB which is still impressive considering it’s size. In contrast our ABT-468-RC generates 110dB and is 40mm diameter, 13mm high. This audible alarm buzzer would be suitable for alarm/warning applications for example, in security or hazardous environments. Sound output will also be influenced by the application itself and environmental conditions.
You will probably have noticed that for the majority of audible alarms the sound is emitted from an opening on the top of the device. You can however purchase buzzers with a sound vent on the side. The ABT-408-RC is a popular audio transducer for designers requiring such a product. The ABT-461-RC is a surface mount option with side sound output.
Some Audio transducers are fitted with a feedback pin or lead. This means they can be run using either DC or AC voltage. If using a square wave (AC), the feedback pin or lead does not need to be connected. The feedback line on a transducer is used to create a voltage which in turn creates a simple, self-oscillating circuit. A reference circuit is provided on the data sheets. This enables the optimum sound levels to be produced. Examples of buzzers with a feedback option are the ABT-468-RC, ABT-467-RC and ABT-469-RC.
The voltage range can be found on the product data sheet for each device. Exceeding the operating voltage is not advisable as it is likely to reduce product reliability. Therefore it is important to establish whether the voltage range of the audible alarm is suitable for your application.

UK Distributor – Alan Butcher Components
We have been distributing Buzzers & Sounders for over 30 years. During this time we have developed strong working relationships with our suppliers. This is essential for us to be able to support our customers with high quality products and technical expertise. We are able to offer customised solutions, working with both customer and supplier to ensure requirements are met quickly and efficiently. We supply to OEMs of all sizes as well as large mainline distributors.
Miniature speakers are also a key part of our audio range. Determining whether to use an audio transducer vs speaker is an important question. Our blog “buzzer vs speaker” provides an overview of points to consider when deciding between audio transducer vs speaker. Click on the link and if you have any questions, give us a call.
In summary, we have looked at Audio Transducer definition, the types of audio transducer, piezo or electro mechanical, points to consider when selecting a product and the decision between audio transducer vs speaker.
