PRLog - Jul. 1, 2011 - Precision Microdrives has recently made the world’s smallest 4mm vibration motor, based on a SMT reflow design available for general sale. The motor has been used in a number of tablet PC / phone products to provide haptic feedback functions.
Since the launch of Apple's iPad, the tablet form factor has become ubiquitous, and more recent models starting to contain our low-profile reflow SMT vibration motors like 304-103. These vibrator motors are beginning to offer every more complicated vibration feedback mechanisms as software OS's like Google's Android start to contain hooks for haptic feedback functionality. App designers are using haptic feedback for alerting, gaming and multi-sense interaction with users, whilst the OS itself uses the miniature vibrating motors to make software buttons feel like real tactile buttons.
The 304-103 4mm vibration motor is a 3V DC surface mount reflow solderable vibration motor. It comes on tape and reel and is designed specifically to be used with a pick and place machine for high speed, high volume feedback solutions like the latest generation of tablet PCs. The motor body including SMD carriage is 4.4mm wide by 3.5mm high. This ultra-low profile is achieved by combining the more traditional C-shape magnetic circuit of larger vibrating motors with miniature moulded neodymium magnets, and makes it ideal for hand-held haptic feedback applications.
Vibrator motors like this are also used frequently for vibration feedback, for example to indicate incoming phone calls, whose purpose is more to alert users of an event rather than replicating the feel of a tactile switches.
Precision’s engineering support team is comprised of experts in the field of applied haptic feedback, particularly for touch interfaces and handheld battery powered products. They are here to help you find the best vibrating motor for your application.
Low-profile vibration motors are just part of a much wider range of 4mm to 7mm Pico Haptic™ vibration motors, which also come other form factors, such as PCB vibrating motors and coin vibrator motors.
