Where motor location for better vibration in electronic design

When engineer start a new project that need a mini vibration motor ,we will have a problem that where to put the motor in.

Our suggestion is put the motor in  four coners.

For example for wearable watch.

The motor is installed on the dial and hits the skin on the surface of the arm through the vibration of the motor

Sensory vibration. Based on the above image, there will be non-contact between the 6 o'clock and 12 o'clock directions and the arm

Phenomenon, its physical sensation will decrease. The recommended reference positions are 3 o'clock and 9 o'clock.

*It is recommended to place the motor at a lower height position on the housing, as it will cause direct vibration force

The vibration transmitted to the surface of the lower shell skin can be intuitively experienced.

When designing the structure of the motor:

1. It is necessary to perform avoidance treatment or sizing on its four corners

The handling of yielding on top

2. The bottom part of the position where the 4mm width measurement is placed

Tilt angle treatment or dimensional allowance is required for placement.

3. It is recommended to add double-sided tape to the bottom of the motor for initial fixation.
