The rated voltage of the rechargeable battery is 1.2V, and the rated voltage of the ordinary battery is 1.5V. The wall clock is designed according to 1.5V of ordinary battery when it is designed. When the voltage of the battery drops to about 1.2V, the wall clock stops due to insufficient voltage. But compared to…
The reason for the slowness is generally caused by the wear between the gears. In addition, the wall clock will slow down as the battery power is insufficient, and this slowness is generally imperceptible. If it is noticeable, it is time to change the battery or wall clock.
An electronic clock is a timing device that displays “hours”, “minutes” and “seconds” in the human visual organs. Its timing period is 24 hours, the full-scale display is 23:59:59, and it has the function of correcting the time and reporting the time. Therefore, a basic digital clock circuit is mainly composed of decoding display, “hour”,…
Time setting: A——Date and time setting/moving B——Hourly alarm switch/increase C—— fixed alarm setting/mobile D——Water bird call adjustment (Take the setting of 10:38 AM on May 24, 2004, as an example) Press “A” key, “Year” flashes, Press the “B” key to set it to “2004”; Press the “A” key again, “Month” flashes, press “B” to set…
The electronic clock is a collective term;
A quartz clock is a category of the electronic clock;
The current electronic clocks are all quartz clocks.
Quartz clocks rely on the natural oscillation of quartz crystals to maintain the accuracy of electronic clocks.
An alarm clock is a clock with an alarm device. It can not only indicate the time but also send out an acoustic signal or other signals at a predetermined time. The movement structure of the alarm clock is mainly divided into two categories: mechanical type and quartz electronic type. Other types such as transistor…
1. The most commonly used alarm clock is the alarm clock with two small bells on the head and a round face. 2. On the front of the alarm clock is the alarm bell and timetable. 3. There are two rotary buttons on the back of the alarm clock, one to control the minute hand…
The size of the clock in the living room should first be considered to match the size of the living room. The small living room is crowded with a large clock, and the living room is uncoordinated with a small clock. The living room wall clock is generally 12 inches, which is approximately equal to…
The quality depends mainly on the movement and appearance of the wall clock. If you want good quality, the key is to choose the brand of wall clock movement, so that the quality is more guaranteed. The rest is to choose the appearance you like, but when choosing an appearance, you should pay attention to…
The vibration mechanism is mainly composed of a balance wheel, pendulum shaft, hairspring, fast and slow needles, etc. The balance wheel will deviate from its equilibrium position and start to swing when subjected to external forces. At this time, the balance spring is twisted to generate a restoring torque. This is the principle of repeated…
