Many people are committed to the introduction of ultra-thin portable speakers, and a revolutionary design that now appears on the Kickstarter will definitely attract the attention of many people, and this is a new type of speaker using PVDF piezoelectric film technology. This piezoelectric film speaker is very thin, only 80 microns thick, even thinner than ordinary paper. Although slim, it can produce very rich levels of sound effects. In addition, the piezoelectric film speaker can also be used as a DIY tool to be added to any third-party developer's products or applications. This ultrathin film speaker represents the future of space technology and can be cut or shaped in any shape. And it can emit a wide range of audio frequency, can bring very good sound effects in a specific space, so as long as you can think of it, it can help us to achieve any possibility. The piezoelectric film polyvinylidene fluoride (PVDF) is a relatively new type of device. The PVDF material is an ultra-thin plastic polymer. The molecules on the surface are arranged in a uniform pattern and coated on the upper and lower surfaces. Conductive coatings, and these coatings can connect PVDF materials and conventional electrical materials to each other. In addition, this material cannot be connected by direct welding because it destroys the PVDF material of the underlying plastic. Therefore, data and current transfer must be achieved by applying a conductive coating. At present, this new ultra-thin speaker material has already started to raise funds on Kickstarter. Self-tapping threaded inserts are suitable for creating heavy-duty, wear-resistant and vibration-proof fastenings in materials with low shear strength, such as aluminium, brass, bronze, cast iron or duro and thermoplastics. Threaded inserts with cutting slot are available in steel and stainless-steel versions.
