Alps Alpine compact haptic reactor "U-Type"

Maintaining high vibration performance, this new model can be installed in tight spaces that were previously challenging. Mass production began in November 2024.

Background

This product was developed primarily for installation in automotive steering wheels and air-conditioning control units. Currently, push switches are commonly used in automotive control units. However, driven by the trend toward higher-quality interior design, touch panels are increasingly replacing traditional switches. While electronic sounds are often employed to confirm operations on touch panels, there is growing demand for vibration-based feedback as an alternative. This approach ensures intuitive usability while maintaining cabin quietness.

Alps Alpine has been providing haptic reactors as tactile feedback devices to meet such needs. However, conventional models, due to their larger size, were difficult to integrate into space-constrained areas like touch panel-based steering wheels and air-conditioning controls. To address this challenge, Alps Alpine developed the "U-Type," which significantly reduces size while maintaining high vibration performance.

Key features

Compact design

• The reduced size allows installation in limited spaces.
• New Product (U-Type): W 10mm × D 19mm × H 5mm
• Conventional Product (Heavy Type): W 23.0mm × D 33.0mm × H 13.0mm

High vibration performance

• By optimising mechanical and magnetic designs, the "U-Type" achieves sufficient vibration force despite its smaller size. It provides an effective tactile response when used in steering wheels or air-conditioning control units.

Product specifications

• Dimensions: W10mm × D19mm × H5mm (excluding FPC, harness, and connector)
• Vibration Acceleration: 4.9Gpp (at 100g)
• Resonant Frequency: 175Hz
• Driving Voltage: 5.5Vpp (sine wave, 30 cycles)
• Terminal Resistance: 6.5Ω

Use cases

Operational Feedback for Automotive Control Devices. In addition, it can be used for warning vibrations during driving and vibration effects in gaming controllers. While the Hybrid Tough Type and Heavy Type Haptic Reactor are also suitable for automotive control devices and gaming controllers, the U-Type is the optimal choice for applications requiring installation in confined spaces.
