This invention discloses a method for preparing an ultralightweight, highly abrasion-resistant TPU / textile composite material for bags and luggage, comprising the following steps: weaving a mesh base fabric using a warp knitting machine; activating and pretreating the surface of a TPU film; coating an adhesive onto the activated surface of the TPU film obtained in the previous step and drying it; hot-pressing the mesh base fabric and the TPU film at multiple points to obtain the TPU / textile composite material; and finishing and shaping the TPU / textile composite material obtained in the previous step. The advantages of this invention include: the prepared composite material possesses multiple advantages such as ultralight weight, high abrasion resistance, softness, strong interface, breathability, and environmental friendliness. It can be widely used in the fabric preparation of various bag and luggage products such as high-end trolley cases, backpacks, outdoor bags, and briefcases, and can also be extended to outdoor products, protective equipment, and other fields, possessing significant industrial application value and market prospects.

This utility model relates to an ultra-lightweight, high-decibel directional speaker suitable for drones, comprising a sound-amplifying cover, a fixed rear seat, a connecting bracket, a power amplifier module, and a sound-generating component. One end of the sound-amplifying cover is tapered, and the fixed rear seat is fixed to the end of the sound-amplifying cover. The sound-generating component is housed within the fixed rear seat. A reflector is fixed inside the sound-amplifying cover, facing the sound-generating component and having gaps between it and the inner wall and end of the sound-amplifying cover. At least one side of the sound-amplifying cover has a mounting groove, and the power amplifier module is fixed within the mounting groove and connected to the sound-generating component. The fixed rear seat also has a connecting bracket fixed to it. This utility model overcomes the technical barriers of incompatibility between lightweight design, high decibel levels, and strong directionality, providing an efficient and reliable audio solution for special operation scenarios of drones.
