vibrating alarm

Common vibration options include built‑in vibrators in bedside clocks (often used together with sound), separate vibration pads or wired shakers you place under a pillow, and vibration‑sensing bike alarms that detect movement and trigger an alert. Some bedside units can run sound, vibration, or both.

Power options vary by model: many bedside alarms are battery powered (commonly AA cells); some are corded and use a DC 5V USB adapter with a small battery (e.g., AAA) as backup. Bike alarms often list specific battery types (for example, AAA for the alarm) and may use a separate battery for a remote.

Wake‑up alarms deliver vibration either via built‑in vibration modes (alarm can sound, vibrate, or both) or through a supplied external vibration pad/wired shaker you place under a pillow or mattress.

Vibrating bike alarms are designed for simple mounting: common methods include double‑sided adhesive tape, zip ties/cable ties, and included brackets or clips depending on the model.

Snooze and repeat behavior varies by model. Examples from listings include a quick press that starts a 5‑minute snooze, and another spec that describes an alarm delay of 15 minutes with up to three repeats (the listing also references 5‑minute repeat intervals). Check the product details to confirm the exact snooze duration and repeat limits.
