It fit just barely in the hole for the spring, I had to cram it a bit, but it made contact with the PCB and I cut it to size, closed up the watch. So I break open a springbar (actually two, the first one is somewhere in my living room lol) and grab the spring. I also learned the "trick" of replacing this spring by tearing apart an old springbar, cutting and using the spring inside one of those for a replacement. I'll be honest, I don't even remember seeing a spring in the movement when I changed the battery, but surmised either whatever dopey watchmaker who changed the battery before me or myself lost the spring. So I opened up my Casio again and didn't see a spring. Really cool to learn how it has to make a circuit with the movement, etc. I had no idea that's what the white "stickers" on the inside of casebacks was. So I got curious and started googling and youtubing and went down the rabbit hole of learning about piezo speakers. The watch is over 10 years old and I keep the hour chime on all my digitals on all the time.I thought perhaps the sound element had simply worn out (how many listings for used digitals do you see where the seller says watch is working except for sound?). hotels, dorms, etc.).Earlier this week I replaced the battery on a Casio CA-53W and afterwards noticed it no longer beeped.

Manufacturing where we help with the mechanical and electrical assembly involved in mounting speakers into customers' boxes and arrays. Sub-contract manufacturing - With our key collaborators, Piezo Source performs sub-contract.Engineering and design - Our team of engineers collaborate with our clients on newĭesigns, materials, and signal processing methods.Manufacturing high quality piezoelectric speakers - Over 100 speakers available in our.Piezo Source supports our customers through: The quality of our bimorph ceramics means that our speakers are also used as a transceiver - speaker and microphone. The speakers manufactured by Piezo Source maintain the high quality originally ensured by Motorola and later by CTS. has been manufacturing and supplying the highest quality piezoelectric speakers since acquiring the exclusive rights, designs, and manufacturing line from Motorola/CTS in 2005. This gives our speakers a much longer lifespan, efficiency and long term performance and stability. Our manufacturing process is roughly equivalent to having a speaker with two crystals rather than one.
