如何实现振动，有人知道吗？

import vibrator from '@ohos.vibrator';
try {
vibrator.startVibration({
type: 'time',
duration: 1000,
}, {
id: 0,
usage: 'alarm'
}, (error) => {
if (error) {
console.error('vibrate fail, error.code: ' + error.code + 'error.message: ', + error.message);
return;
}
console.log('Callback returned to indicate a successful vibration.');
});
} catch (err) {
console.error('errCode: ' + err.code + ' ,msg: ' + err.message);
}
