My new digital alarm clock is emitting a high frequency noise that is starting to drive me insane.
Is there anything I can do about it before I take it back. I've already tried hitting it multiple times btw.

Coil whine, indicator of cheap chinesium dogshit. Have you considered buying and Omega? I get a lot of attention despite it being 5x less than a Rolex
I don't want a watch, I want a alarm clock.
That appears to be a TEAC alarm clock.
As far as I’m aware that must be the rolls royce of alarm clocks, unless TEAC sold their name to china.
Like RCA.
and Sunbeam.
and Sansui.
My sister got it for me and she said she looked up what the best alarm clocks are and apparently TEAC came up often. It's perfect other than the noise.
>TEAC
Weird way of spelling Sony.
Get a Sony Dream Machine. Best alarm clock by far.
I want a new one because my old one's display was going so I couldn't tell the time at certain times.
LED displays only get slightly dimmer after about 50 years. It’s more likely an electrolytic capacitor went dry.
This classic Dream Machine model shares a lot in design with the one in the OP.
This one is functionally identical to the one before, in a very neat cube package. Also in white.
I have this one. It has lasted me many years, but it runs fast.
running fast is a nigtmare.
to reset it, you have to cycle the time.
I had a string of several alarm clocks that ran fast, I just got one the other day that runs slow.
All the cheap ones, and the microwaves, are synched with the 60 Hz mains and stay accurate within a minute over a year.
I guess a lot of the ones that run fast (or slow) use a crystal so they can use the same circuit for 50/60 Hz without tapping a transformer or using an AC adaptor.
>cycle through
Wrong. The dream machine has a time + and time - button both for setting the clock and the alarm. It's a perfect design. And all plugged in clocks use the 60hz mains as reference. I find it runs fast on battery backup when there is a power outage though which is arguably better than running late.
> sony has a - time button
cool. that should be some kind of law, especially in daylight savings time victorian era technology places.
> all mains clocks use ac ref
No. I took a fast one apart to see why it was wildly off… it gains a minute per day. I’ve got alarm clocks in almost every room, none of them are off during the year except this one.
First off, it’s not the original sanyo alarm clock chip, it’s a cheap knock-off chip on a carrier board to make it the same dip pinout as the original.
Second, they do attempt to tap the winding, but when they cloned the circuit, they fricked it up, so it always runs in battery back-up mode using the crystal—even when using AC. It never could have worked, it’s missing some components and a diode. Probably to save 1 cent.
I guess the 2-second test they’ve been giving it at the factory was good enough. That’s chinese stuff for you: it superficially looks like a real clock radio, but it doesn’t actually to the job.
I have a sony and it buzzes.
Not only that, it gets off sync.
I have a clock, but I want a digital one to see at night in the dark.
ONE FITTY
Open the clock up and hot glue anything that looks like a coil. Problem solved
Philips Wake-up Light
Works fine for me. All i did was replace the burnt out bulb for a 2200k led and add a 2000 ohm resistor
>not building your own clock.
You all are a bunch of posers...
To be fair I have some projects at home that look like "clocks" but my name is not Ahmed.

Did you try hitting the snooze button?
