How Does Audio TimeSync Work?
Most smart wall clocks rely on WiFi or Bluetooth to sync time. That means configuring routers, pairing devices, installing apps — and hoping the connection stays stable. OVOSONO takes a fundamentally different approach.
With Audio TimeSync, the OVOSONO Circle 350 receives the exact time through an ultrasonic audio signal. No network, no pairing, no app. Just hold your phone near the clock — done.
How Audio TimeSync Works
The synchronization process takes just a few seconds and works with any device that has a speaker:
- Open ovosono.com/timesync on any device with a speaker
- Hold the device near the OVOSONO Circle 350 (within about 30 cm)
- The clock receives the encoded time signal and sets itself — done in seconds
The technical elegance lies in the detail: time data is transmitted on ultrasonic frequencies above the range of human hearing. You hear nothing — the clock understands everything. And it works with any smartphone, tablet, or laptop.
Advantages Over WiFi and Bluetooth
Audio TimeSync eliminates the typical weaknesses of wireless connections. A direct comparison shows the differences:
| Feature | Audio TimeSync | WiFi | Bluetooth |
|---|---|---|---|
| Setup complexity | None | Router needed | Pairing needed |
| Network dependency | None | WiFi required | Device proximity |
| Privacy | No data sent | Connected to internet | Paired device |
| Power consumption | Only during sync | Continuous | Continuous |
| Works offline | Yes | No | Partial |
Conclusion
Audio TimeSync is the simplest, most private way to sync a wall clock. No accounts, no passwords, no network — just sound. A technology that does exactly what it should, and nothing more.
FAQ
- What is Audio TimeSync?
- Audio TimeSync is the synchronization technology of the OVOSONO Circle 350. The clock receives the current time via an encoded audio signal from your smartphone — without WiFi, Bluetooth, or an app.
- Does OVOSONO need WiFi or Bluetooth?
- No. The OVOSONO Circle 350 needs neither WiFi nor Bluetooth. Time synchronization works exclusively via audio signal from the smartphone.
- How accurate is Audio TimeSync?
- Audio TimeSync synchronizes the clock to the second. The internal quartz clock is then so precise that re-synchronization is only needed every few months.
