Description

Low Power Car Bluetooth Handsfree Phone

technical field

The utility model relates to a vehicle-mounted Bluetooth hands-free phone.

Background technique

Bluetooth (Bluetooth) technology is a short-range wireless communication technology standard. Bluetooth technology has been used as a standard configuration of mobile phones in today's society, and more and more mobile phones also have Bluetooth functions. Bluetooth technology has been accepted by more and more people due to its wireless and anti-radiation advantages, and the market demand has become an obvious upward trend. At present, Bluetooth is most widely used in the field of mobile phones. When making a call, Bluetooth wireless communication technology can be used to transmit voice and realize the wireless connection between the headset and the mobile phone. Moreover, in order to ensure driving safety, traffic rules also stipulate that the driver can not make or answer mobile phones during driving, which brings inconvenience to the use of some mobile communication devices on cars. In view of this, a kind of car bluetooth hands-free phone has been developed on the market at present, and it comprises bluetooth module, the antenna that is connected with bluetooth module, microphone, car power plug, amplifier, the loudspeaker that is connected with amplifier, although it can carry out hands-free speech Calling, however, needs the user to manually open it every time it is used, which is very inconvenient to use.

Utility model content

The purpose of the utility model is to propose a low power consumption vehicle bluetooth hands-free phone, which can solve the problem of manually opening the bluetooth module.

In order to achieve the above object, the technical scheme adopted in the utility model is as follows:

The low-power vehicle bluetooth hands-free phone includes a bluetooth module, an antenna connected to the bluetooth module, a microphone, a car power plug, an amplifier, a speaker connected to the amplifier, a vibration sensor for detecting vehicle vibration, and a A switch control circuit that controls the opening and closing of the Bluetooth module according to the signal input by the vibration sensor.

Preferably, the vibration sensor is connected with the Bluetooth module through a switch control circuit.

The utility model has the following beneficial effects:

After the vibration sensor detects the vibration of the vehicle (such as the vibration generated by the door opening, the ignition of the car engine, etc.), the vibration signal is input to the switch control circuit, and the switch control circuit can start the Bluetooth module according to the vibration signal, so that the Bluetooth module can be connected with the latest successfully connected The Bluetooth external device (such as a mobile phone) performs automatic matching, so as to realize the function of automatically starting the Bluetooth module, and the user does not need to press any buttons, which is very convenient to use.

Description of drawings

Fig. 1 is a schematic structural diagram of a vehicle bluetooth hands-free phone according to a preferred embodiment of the present invention.

Detailed ways

Below, in conjunction with accompanying drawing and specific embodiment, the utility model is described further:

As shown in Fig. 1, a kind of low power consumption car bluetooth hands-free phone, it comprises bluetooth module, the antenna that is connected with bluetooth module, microphone, car power plug, amplifier, switch control circuit, the loudspeaker that is connected with amplifier, and switch control Circuit connected vibration sensor.

The vibration sensor is used to detect vehicle vibration. The implementation method is to pre-design the vibration frequency that the vibration sensor can receive, such as the vibration frequency generated by the opening and closing of the car door, the vibration frequency generated by the engine ignition, etc.

The switch control circuit is used to control the opening and closing of the bluetooth module according to the signal input by the vibration sensor.

In addition, the switch control circuit can also add an automatic power-off function to achieve low power consumption. When the switch control circuit detects that the Bluetooth module is disconnected from the Bluetooth external device for more than 10 minutes, the Bluetooth module is controlled to enter a sleep state, and the Bluetooth module is not activated until the vibration sensor receives the vehicle vibration again.

Using the vehicle bluetooth hands-free phone of this embodiment, the user does not need to worry about the power consumption of the battery if the bluetooth hands-free phone is not turned off, which has the advantages of energy saving, environmental protection and low power consumption. At the same time, there is no need to manually open it, which greatly improves the safety and convenience of driving.

For those skilled in the art, various other corresponding changes and modifications can be made according to the technical solutions and ideas described above, and all these changes and modifications should fall within the protection scope of the claims of the present invention .
