In addition, the control component 5 is high in accuracy and sensitivity of adjusting the controlled function, and the ceramic ring 1 is used as an acoustic-electric transmission component, so that the structural compactness and the space utilization efficiency of the intelligent watch are improved.
Alternatively, referring to fig. 2 and 3, a plurality of the polarization parts 11 are disposed on a side of the ceramic ring 1 close to the back shell 3.
Specifically, a plurality of polarization parts 11 are ultrasonic transmitting end 111 and ultrasonic receiving end 112, form the ultrasonic wave propagation region between ultrasonic transmitting end 111 and the ultrasonic receiving end 112, set up a plurality of polarization parts 11 set up in ceramic circle 1 is close to behind one side of backshell 3, the ultrasonic wave propagation region can include the backshell (the backshell is the same can transmit the ultrasonic wave in the entity) and the backshell deviates from the local space of ceramic circle 1 one side, and this local space can be the backshell deviates from the space within 2mm of ceramic circle 1 one side, also can be the backshell deviates from the space within 1mm of ceramic circle 1 one side. When a user wears the intelligent watch, the arm of the user inevitably touches the local space, so that the ultrasonic wave in the ultrasonic wave propagation area can be obviously changed, and the sensitivity of the control component 5 for adjusting the controlled function is improved.
Alternatively, referring to fig. 3, a plurality of the polarization parts 11 are uniformly distributed on the ceramic ring 1 in a ring shape.

Specifically, the high-frequency sensor 4 may be connected to the polarization part 11 by a wire, but since the polarization part 11 is a part of the ceramic ring 1, that is, the polarization part 11 is still substantially a ceramic material, in order to form a stable connection between the high-frequency sensor 4 and the polarization part 11, a pad 12 may be provided on the polarization part 11.
Optionally, a temperature control assembly is arranged in the ceramic ring 1.
Specifically, the ultrasonic wave transmitting end 111 and the ultrasonic wave receiving end 112 are part of the ceramic ring 1, that is, the ultrasonic wave transmitting end 111 and the ultrasonic wave receiving end 112 are still substantially ceramic materials, and the electric signals transmitted and received by the ceramic materials are changed under the condition of temperature change. When the user wears the smart watch, the temperature of the ceramic ring 1 may be affected by the temperature of the human body, and the electric signals transmitted and received by the ultrasonic transmitting end 111 and the ultrasonic receiving end 112 may also be changed. The temperature control assembly is arranged to control the working temperature in the intelligent watch to be within a certain temperature, namely, the temperature of the ceramic ring 1 is kept stable, so that the fluctuation of signals transmitted and received by the ultrasonic transmitting end 111 and the ultrasonic receiving end 112 is reduced, and the service life of the intelligent watch is prolonged.
Referring to fig. 8, an embodiment of the present application provides a method for controlling a smart watch, including:
s101, collecting ultrasonic signals of an ultrasonic propagation area by a control assembly;
s102, comparing the ultrasonic signal with an initial ultrasonic signal when the intelligent watch is not worn, and judging whether the ultrasonic signal is consistent with the initial ultrasonic signal;

Specifically, when the user wears the smart watch, the skin of the user touches the ultrasonic propagation region, so that the absorption and reflection modes of the sound wave are changed, the ultrasonic signal is changed, that is, the ultrasonic signal is inconsistent with the initial ultrasonic signal, the change can be sent back to the control component, and after the control component detects that the user wears the smart watch, the controlled functions of the smart watch, such as the functions of display, vibration, voice, monitoring and the like of the smart watch, can be started. In addition, when control assembly detected when the smart watch was not worn by the user, namely the user lifted off behind the smart watch, control assembly can close functions such as the demonstration, vibration, pronunciation and the monitoring of smart watch to improve the time of endurance of smart watch, improve user's use experience.
Optionally, a tamper-proof module is provided within the control assembly.
Specifically, when the smart watch is not worn, a situation that the ultrasonic sound production of the ultrasonic propagation region changes due to the fact that water drops drop on the outer surface of the back shell may exist, and in order to avoid that the control assembly is triggered to adjust the controlled function after the water drops drop on the outer surface of the back shell, an anti-interference module may be preset in the control assembly. The interference prevention module can store the influence of sweat, rainwater and other water drops in the control assembly, and improves the control assembly adjusts the sensitivity of the controlled function.
