Description

Technical Field

[0002] Currently, there are two main types of doorbells on the market: push-button self-generating doorbells and battery-powered doorbells. Push-button self-generating doorbells generate electricity through pressing. Specifically, when a user presses the doorbell button, an internal piezoelectric or electromagnetic induction device generates a small amount of electrical energy. This energy is stored and used to drive the doorbell button to send a wireless signal. Because the self-generated power is relatively low, it requires a high transmission rate from the internal radio frequency chip. Therefore, push-button self-generating doorbells can only achieve simple triggering and transmission functions, and their stability is relatively poor.

[0003] Battery-powered doorbells typically use dry cell batteries or rechargeable batteries. They are triggered by a button, and the signal is transmitted to the receiver via radio waves to produce a ringing sound. However, battery-powered doorbells require regular battery checks and replacements.
