What is the purpose of the mic hole in a car navigation system?

[DiRonan]

The English full name of the mic hole on a car navigation system is 'microphone,' which means it is essentially a microphone. Therefore, the mic hole is responsible for collecting sound for the car navigation system. Many voice-controlled navigation systems often include this feature, and currently, many vehicles integrate the navigation system with the car itself. More details about the navigation mic are as follows: 1. Introduction one: Modern navigation systems can be voice-controlled. To enable voice control, there must be a device capable of successfully receiving sound signals, converting them into electrical signals, and then transmitting these signals to the navigation system's internal computer to recognize relevant information. 2. Introduction two: Currently, the information used by car navigation systems is still quite rudimentary. Therefore, depending on the actual situation, the car navigation system must have such a microphone hole. When using the navigation system, drivers must rely on it as an auxiliary tool; otherwise, there may be safety risks while driving.
