This is a wireless doorbell and its design inspiration comes from pebbles, such as the smooth round shape, delicate touch and transparent texture, whose characteristics enable customers to experience the friendliness and reliability of the product. Concise and soft lines can be seen from the exterior of the bell. The plastic translucent lampshade presents an obvious contrast against its main body, highlighting soft light effects and striking a balance between function and beauty. As a whole, the customer-friendly appearance is compatible with most indoor environments, such as single apartments, home offices and other private places. Moreover, the breathing light pattern is applied to promote a mild user experience, allowing the hearing-impaired to use the product without problems.
