Example Embodiment

[0022] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples are only used to explain the present invention, but not to limit the scope of the present invention.

[0023] like figure 1 As shown, a schematic structural diagram of a radio frequency wireless system for a car headset.

[0024] The design requirements of various indicators of each module meet the requirements of vehicle regulations.

[0025] In the initial state, the RF headset has completed the pairing process with the RF module. At the same time, in order to facilitate maintenance and replacement, both the RF headset and the RF module support the re-pairing function. The radio frequency module can send audio signals to the wireless headset 1, and can also receive the radio frequency communication connection and disconnection (that is, the state of taking out and putting back the headset) from the wireless headset 1. The vehicle wir...

Abstract

The invention relates to the vehicle telephone communication technical field, particularly to a wireless earphone system for enhancing the privacy of vehicular communication. The vehicle earphone radio frequency wireless system comprises a vehicle terminal, wireless earphones and a switch; an audio output end of the vehicle terminal is connected with an input end of a radio frequency transmitter when the switch is used in the wireless earphones; a voice signal is modulated to be sent to the wireless earphones through the radio frequency transmitter; the audio output end of the vehicle terminal is connected with an internal speaker when the switch is not used in the wireless earphones. The vehicle earphone radio frequency wireless system is simple and easy to implement, the privacy of the vehicular communication can be effectively improved, and the safety of the driving of a vehicle owner is improved due to the fact that the driving of the vehicle owner is not affected.

Description

technical field [0001] The invention relates to the technical field of in-vehicle telephone communication, specifically a wireless earphone system for enhancing the privacy of in-vehicle communication. Background technique [0002] With the continuous development of society and the improvement of people's living standards, and the popularization of family cars, people's time in the car has increased significantly, and in-car calls are inevitable. For driving safety, Bluetooth hands-free calling is a good solution, and the car Bluetooth system has been greatly developed. However, user privacy requirements are taken into consideration. Sometimes private calls are necessary, such as involving commercial secrets, personal privacy, etc. For some users who often drive but prefer headphones, the introduction of Bluetooth headphones is not a perfect solution. Because most of the bluetooth mobile phones currently on the market cannot support the connection of two bluetooth hands-f...
