Product Name: CET-4 / CET-6 Radio; Target users: CET-4 and CET-6 candidates; Design thinking: For examinees, the radio is only used for a while on the day of the exam (as far as I am concerned, the people around me are also like this). The usage rate of the radio is not very high. By observing the existing CET-4 and CET-6 radios on the market, it is found that there are many function keys for the radio. In view of the low utilization rate, the LCD screen is designed to display the time when not in use in addition to the channel, so that the radio can also be used as a small desktop clock at ordinary times, and the function keys are simplified. In addition to the necessary channel, volume and time adjustment keys, all other function keys are discarded. The appearance is a little rounded on the square shape. In addition to breaking the square and square feeling, it is also convenient for the radio to be taken in the subsequent packaging design. The radio product is very simple. In fact, in the process of dismantling the radio, the internal structure and components are not very complicated. This time, through dismantling common items in daily life and my own use experience, I will do a simple design exercise (modeling, rendering), and then I plan to do several different modeling rendering exercises.
