Intercom voice chip solution

The voice chip intercom is a mature solution in the collection of intelligent voice chip audio equipment application solutions. This solution project can produce sample chips for testing within 30 minutes at the fastest. It is a multi-functional intelligent, and the disposable voice chip will perform voice broadcast when used. Intelligent audio equipment related products.

performance

1. Add a voice function for channel broadcast, which is more convenient during frequency matching. It will be more intuitive to display the frequency band information when there is a voice broadcast when the user switches channels, such as when emergency situations such as traffic control or fire rescue occur and there is no way to see the screen. .

2. Adding a voice IC can allow users to better understand the status of the machine and provide prompts in the case of being shaken unconscious or shaken to death;

3. The intercom will record daily voice content, which can supervise members to complete daily tasks and clarify responsibilities when an accident occurs;

4. The voice IC can have a storage time of 8 hours or even 30 days, so there is no need to worry about losing the content in case of power outage.

Voice chip selection

The one-time voice chip development engineer analyzed the commonly used smart voice chip audio equipment application development solutions on the market, and evaluated that the GY58170A of the OTP voice chip series can be used as the main control chip.

working principle

The walkie-talkie is a broadcast mode, one transmitter and multiple receivers. If two walkie-talkies transmit on the same frequency band, they will interfere with each other. More advanced walkie-talkies use encryption technology and can broadcast multiple stations simultaneously on one frequency band. The walkie-talkie can also have a main station. After receiving the walkie-talkie signal, the main station amplifies and broadcasts to a wide range. This is also networking, but the range is relatively small. The way mobile phones and computers connect to the Internet is different from that of walkie-talkies. They are all point-to-point. Since the wireless bandwidth is limited, the coverage area of a mobile phone base station is smaller than that of a walkie-talkie station. It is generally only a few meters, and there are also a few hundred meters in downtown areas. This is done to reduce the number of simultaneous calls and ensure that the coverage area is within the limited bandwidth. You can make multi-way calls comfortably.
