Description

hands-free device

The utility model relates to a hands-free receiver device, in particular to a hands-free receiver base suitable for various types of hands-free receivers and various places.

Generally, in order to avoid being harmed by electromagnetic waves when using a mobile phone, or for convenience in doing things and driving safety, etc., the user often cooperates with a hands-free handset device in addition. If the mobile phone can cooperate with a hands-free receiver, when answering the phone, both hands can continue to do other tasks, such as typing, driving, etc., and the user can also keep an appropriate distance from the mobile phone by using the hands-free receiver. , to avoid the interference of harmful electromagnetic waves.

It is extremely inconvenient to hold a mobile phone while doing things while listening to the phone. You must tilt your head and clamp the phone with your neck to prevent the phone from falling. Therefore, when the user tilts his head to do things, his work efficiency will be greatly reduced. Mistakes will happen, and even those working on large machines can cause irreparable accidents if they are not careful. In addition, it is very dangerous to hold a mobile phone and listen to the phone while driving. Not only can you not concentrate on driving, but in case of an emergency, you will not be able to effectively and completely control the steering wheel because of holding a mobile phone, which will cause danger. There is a speakerphone. The hands-free device allows the user to receive or send voice messages normally without taking the mobile phone by hand when working, driving or engaging in other inconvenient affairs. Significantly improve the safety of busy people or attentive drivers.

Most of the common hands-free handsets on the market are car-type hands-free handsets, which can be divided into the following types:

The first kind is as shown in Figure 1, is a transmission line 1, and one end of this transmission line 1 has a socket 10, in order to connect the connector (not shown) below a mobile phone, and the other end is then provided with a socket 11, the connector 11 can be inserted into the cigarette lighter hole of the car (because the cigarette lighter hole of the car can supply DC power), and the connector 11 is provided with a horn 111, a microphone 112 and a plug for earphones. Connected earphone hole 113, when the earphone is inserted into the earphone hole 113, the sound is originally uttered by the speaker 111 and turned by the earphone. But this device has many deficiencies. Firstly, the insertion port 10 of the transmission line 1 is only suitable for one type of mobile phone. If the user replaces the mobile phone, the entire transmission line 1 must be replaced, and the insertion port cannot be used alone. 10 for replacement, and when the driver wants to listen to the sound with earphones, he must insert the earphones in the earphone hole 113. This action can be easily completed if the car is not moving, but if the car is moving, not only It cannot be done easily and may also be dangerous for the driver. Therefore, its applicability is low, and it is inconvenient to use.

The second is to combine the car hands-free handset with the car's audio system (also known as 2Din audio system). Usually, the car's hands-free handset and audio system have been assembled when the car leaves the factory, and it must be When ordering a car, tell the manufacturer the mobile phone model to be used in advance to facilitate installation. Therefore, the applicability of this design is extremely low.

Above-mentioned two kinds of vehicle hands-free receivers all need seat body in addition, and seat body is used for placing mobile phone, and seat body is fixed in the appropriate position place in the car in addition, so that the driver puts hands-free receiver.

As shown in Figure 2, there is another car hands-free handset combined with the base body, which can make the base body have the function of hands-free handset, unlike the aforementioned base that only has the function of placing mobile phones. The hands-free device 2 for vehicles has an accommodating space 20 for placing a mobile phone, a speaker 21 , a microphone 22 and a jack group 23 . The accommodating space 20 has a socket port 201, which is used to connect with the connector (not shown) at the bottom of the mobile phone. In addition, on the left and right sides of the accommodating space 20, there are respectively a clamping 26, these two clamping components 26 are arranged in a mode with elastic clamping force, and the width between the two clamping components 26 can be automatically adjusted according to the width of the mobile phone, and when adjusted to an appropriate width, it can be used The mobile phone is fixed by the frictional force between the clip 26 and the mobile phone. But this kind of hands-free hands-free device 2 for vehicles has the aforementioned shortcoming of low applicability in the past, because the socket supply port 201 in the accommodation space 20 can only be aimed at a type of mobile phone, such as the user changes the mobile phone , the entire speakerphone unit 2 must be replaced. In addition, although this hands-free handset device 2 has a clamping piece 26 on the left and right sides of the accommodating space 20 to clamp the mobile phone, most of the external connectors of the mobile phone are arranged below it. And when driving, the unevenness of the road surface causes the car to vibrate up and down. Therefore, it is extremely impossible to try to fix the mobile phone with the clamping parts 26 on the left and right sides of the accommodating space 20, and the up and down vibrations produced by the car will be extremely impossible. Vibration is easy to disengage the connector at the bottom of the mobile phone from the socket 201, causing a short circuit and making it unusable.

As far as the aforementioned speakerphone is concerned, it is only suitable for a specific brand and specification. Therefore, when replacing the speakerphone, if the connector positions of the two mobile phones are too different, or the specifications of the connectors are different, Just can't continue to use the original hands-free handset, but needs to purchase another conforming hands-free handset. Therefore, the applicable elasticity of the hands-free handset in the past to the mobile phone is very low, and the clamping part of the hands-free handset seat body for the vehicle in the past utilizes the friction force between the mobile phone to clamp the mobile phone, and the clamping force Insufficient, and the clamping force direction is inconsistent with the direction of the mobile phone connector insertion, often because of bumps and vibrations during driving, the mobile phone cannot be firmly placed in the seat.

In addition, no matter the above-mentioned hands-free hands-free device in the past, because the use of the speaker and earphones of the hands-free handset is to use the earphones to listen to maintain privacy, the earphones must be plugged into the jack group of the hands-free handset immediately. , and this plugging action will inevitably cause concerns about driving safety.

The purpose of the utility model is to provide a hands-free receiver base suitable for a variety of different types of hands-free receivers and a variety of different places.
