I was cheated! How much profit can I get from this USB microphone? [Copy link]

 

The reason for this is that the epidemic has caused me to work remotely from home, and I have to hold three or four remote meetings every day. My colleagues reported that my microphone is noisy because the mic of the laptop is very close to the fan. When the fan turns, the noise is relatively loud. Therefore, I want to get an external microphone. The laptop only has a headphone jack (without a microphone), so I have to choose one with a USB interface. This is not easy. I just searched on JD.com and placed an order. I bought the "Newmine ZM02" priced at 59;

I thought this microphone which cost more than 50 yuan couldn't be too bad, but when I got it back and tried it, it was terrible.

The current noise from this microphone is extremely loud, a buzzing sound, louder than that of a fan, and has the same effect as the USB sound card I bought for a few dollars.

I was depressed. I bought the product for nothing. The filtering of this product must not be done well. I thought, I should take it apart and have a look. Maybe I can fix it:

After I took it apart, I was stunned. There was a touch switch on the back, and that was all. I immediately understood the quality of this product. At this point, I couldn’t help but sigh: Damn, that’s too much profit!

Forum experts, do you have any knowledge of the relevant industry? What can make this product sell for more than 50 yuan?

It seems that the cost is all in the shell and advertising.

More than 50, good quality

The problem is that the quality is too poor to justify

The solution is similar to that of a USB sound card, but the high cost lies in the shell mold.

The market demand is too small, and the gross profit margin must be high for people to be willing to do it.

Don't be so mean and take it apart... Just return it and file a complaint.

Newman is also an old brand. I used to use this brand's 128M MP3 player. The impression it left on me was that it was affordable, but the sound quality was not as good as other music phones of the same period.

I didn't expect that after so many years, the things I made are still like this.

It seems that you can't just buy things on a whim. You need to do more research and read reviews, and be cautious when buying niche products.

I searched again today and found that 50 plus is basically cheap. It seems that the saying "cheap goods are not good" is true.

This is the only reasonable explanation. The sales of this product are really not that high. Even if the quality is quite good, it is a waste of effort. No one cares about it.

I chose to support it because it is an old brand, thinking that the quality can be guaranteed, but the result is unexpected. I have a Logitech camera, and the microphone it comes with is very good.

So there is a reason why this old brand has been tepid for so many years.

Buy a recorder and plug it in, it works well~

Can a voice recorder be used as a USB microphone? Don't lie to me

USB MIC is too rare, and this type is for use with PCs. The demand is too small, so it is not surprising that the effect is not good. However, the obvious current sound is not normal. Check the analog part of the circuit (MIC preamplifier circuit), enhance the decoupling, replace the MIC wire if necessary, and try connecting it separately with a shielded wire.

If you are looking for effective results, you can consider using peripherals for live streaming, which are not much more expensive.

This product is a single-chip solution. USB and analog amplification are all built into one chip. There is no room for modification. I regret not having done it in one step and directly built a live broadcast device.

Today I happened to see a "Little Bee" for mobile phones. It doesn't have a recording function, so the price is not high, just over one hundred yuan. It can be expanded to connect to multiple external MICs and can be used with mobile phones for interviews and recording programs.

Keep the shell and use MEMS microphone + STM32 to DIY one yourself

Nowadays, everyone knows that electronic products, power supplies, PCB boards, etc. are making huge profits. Many things are very low cost.

The saying "cheap goods are not good goods" is actually misleading. Many unscrupulous merchants sell you goods worth hundreds of yuan for goods worth only tens of yuan, and you will think that their goods are better.
