Description

Hands-free handset for mobile phone

The utility model relates to a mobile phone, in particular to a hands-free handset device for the mobile phone; the main purpose is to set the loudspeaker and the microphone on the same serial controller, so that the phone will not be connected when answering the phone while driving a car. Line restrictions for ease of use.

In a car, when the driver hears the sound of the phone, if he separates one hand to pick up the phone to answer the call, he can only use one hand to control the car, which will naturally affect the sensitivity of the action and easily lead to dangerous driving For this reason, a hands-free handset device has been developed. The conventional hands-free handset device 1, as shown in FIG. The conductive seat 12 of the cigarette lighting hole of the car is formed, wherein the controller 11 can be plugged into the interface 21 of the phone 2, and the controller 11 is connected to the conductive seat 12 with a connecting line 13, and the conductive seat 12 can be connected to the front end. The plug-in end of the plug is inserted into the cigarette lighter hole of the car to obtain the power required for the call. When a call comes in, it can be directly connected to the phone 2 through the controller 11, and the sound of the phone can also be transmitted through the conductive seat 12. The loudspeaker 14 is sent out, and the user's reply is transmitted through the microphone 15 on the controller 11. This structure can indeed achieve the purpose of talking without using the handset 2, and can continue to control the car with both hands. The controller 11 and the conductive seat 12 are connected by the connecting wire 13, therefore, the position of the phone will be limited by the connecting wire 13, and also because of the existence of the connecting wire 13, the inside of the car will appear messy and will be disturbed. It will have a certain impact on the activities of the driver and the front seat passengers. If you do not pay attention, the connecting wire 13 may be touched by the movement of your hands, and a pulling force will be formed on the dialogue phone 2 and the conductive seat 12, resulting in power interruption and even a phone failure. 2 failure phenomenon.

Another person has developed another hands-free handset device 3, as shown in Figure 2, it is to use the power supply of the phone itself, mainly composed of a controller 31 and an earphone 32, wherein the controller 31 can be connected to the plug-in terminal 311 Insert the card into the interface 41 of the phone 4, the earphone 32 is inserted into the insertion hole 312 of the controller 31 by its receiving end 321, so that the earphone 32 and the controller 31 are connected as a whole, and the output end 322 of the earphone 32 Then it can be plugged in the user's ear so as to receive the voice of the incoming call. At the same time, the power supply of the earphone 32 is close to the output end 322 and a microphone 323 is set to transmit the user's reply. Although this structure can also achieve The function of the hands-free earpiece, but the earphone 32 is plugged in the ear for a long time, which will cause an uncomfortable feeling. Simultaneously, the same as the aforementioned habitual user, the power cord of the earphone 32 will also have an impact on the driving action and cause messy in the car.

The primary purpose of this utility model is to provide a hands-free hands-free device for mobile phones that is easy to use. The loudspeaker and microphone are directly installed on the serial controller, so as to achieve convenience in use and make the interior of the car tidy.

In order to achieve the above object, the utility model takes the following measures:

The hands-free handset device of the mobile phone of the present invention includes a serial controller, a loudspeaker and a microphone; the front end of the serial controller is provided with a plug-in terminal for inserting a card on the phone to connect to the interface of the phone, and the power supply of the phone is used as the serial controller energy;

It is characterized in that the loudspeaker and the microphone are arranged on the controller.

The loudspeaker and the microphone can be arranged in a direction perpendicular to each other.

The utility model is described as follows in conjunction with accompanying drawing and embodiment:

Description of drawings:

Figure 1: Exploded view of a conventional device.

Figure 2: An exploded view of another conventional device.

Fig. 3: An exploded view of a preferred embodiment of the utility model.

Fig. 4: The block diagram of the circuit of the preferred embodiment of the utility model.

Please refer to Fig. 3 at first. The hands-free receiver device provided by the utility model is powered by the phone itself, and is mainly composed of a serial controller 5 plugged into the phone 6, wherein the serial controller 5 can be in any suitable shape, In the accompanying drawings, a rectangular body will be used as an example for illustration. As shown in the figure, a protruding insertion end 51 is extended in the center of the front end of the controller 5, which can be plugged into the interface 61 of the phone 6. Connect the serial controller 5 and the phone 6 as a whole, and obtain the power required for the operation through the phone 6, set a speaker 52 on the upper end surface of the serial controller 5, and set a microphone at one side end surface , the utility model is mainly that the loudspeaker 52 and the microphone 53 are arranged on the controller 5 together.

The use state of the present utility model, as shown in Figure 4, the interface of phone 5 is connected with the power supply of phone, and the serial controller of the present utility model can obtain the required power supply of action after inserting the card in the interface of phone, and continuous control A control circuit is set in the device 5. When the phone receives an incoming call, the received voice is first amplified by the receiver amplifier circuit, and then sent out through the loudspeaker, so that the user can clearly hear the incoming call, and the user returns the call. The sound is sent out through the microphone, and then the voice of the caller is amplified by the call amplifier circuit, so that the caller can hear the call back clearly. There is also a call attenuator in the controller to prevent the caller's voice from passing through. The microphone produces feedback, that is, it is used to obtain a balance point in order to obtain the best call quality. As far as the speech attenuator is concerned, it is a device that is already available in a conventional telephone, and it is a conventional technology, so it will not be described in the description. Another detailed explanation.

Compared with the prior art, the utility model has the following effects:

Because the loudspeaker 52 and the microphone 53 are arranged on the single controller 5 together, therefore, the utility model does not need to be provided with connecting wires, and generally all can be provided with a phone socket at the driver's seat of the car for the positioning of the plug-in card of the phone, so In the utility model, after the phone card is placed in the phone socket, there is no connection line, compared with the conventional hands-free receiver device, the utility model not only does not appear messy in the car, but also improves the appearance of the car More importantly, because there is no connection wire, it will not hinder the actions of the driver and the passengers on the side, which can improve the smoothness of driving actions, thereby improving the safety of driving, and at the same time, no calls will occur The phenomenon of power failure in the middle achieves the convenience of use, and the speaker and microphone on the controller are arranged vertically. In this way, the feedback phenomenon during the call can be reduced, and the voice of the call can be clearer.
