Voice-controlled shower patent

As long as you apply for a patent, even if you apply today, there will be an announcement online immediately! I have been to the website of the Intellectual Property Office, and there is no patent for this number. You should have been cheated! If you don't believe me, check it on the website of the Intellectual Property Office at /sipo/. This product will have a certain impact on the baby, because the younger you are, the wider the frequency range of the sound you hear. If your baby shows anxiety or headache during use, then I suggest you not to continue using this product! After all, the baby is the most important!
