Description

Handsfree available for wire or wireless mic simultaneously}

The present invention relates to a hands-free installation of a wired / wireless microphone for use in a vehicle for making a call possible without taking a mobile phone installed inside the vehicle. More specifically, it is possible to use D.C. wireless microphone and wired or wireless microphone simultaneously using the FM method. It is equipped with a plug, and it is possible to use 3 pole and 4 pole jacks at the same time for compatibility with domestic and overseas mobile phones.The CLA part is made of detachable cigar jack so that it can be used as both CLA type and dash board type. The present invention relates to a handsfree device capable of simultaneously using a wired / wireless microphone made of a removable device.

Recently, mobile phones, which are portable communication terminals including cellular phones and PCS phones, have become widespread, but when used while the vehicle is in use, the mobile phone reduces the driver's ability to concentrate on the road ahead, which significantly affects safe driving. Go crazy.

In other words, when using a mobile phone while driving a vehicle, the driver must take the mobile phone by hand, and thus the steering force of the steering wheel is not only deteriorated. In order to call the driver, the driver's ability to focus on the front of the vehicle decreases due to the process of manipulating a plurality of buttons installed on the mobile phone. Therefore, if the user directly takes the mobile phone while the vehicle is in use, it significantly affects the safety operation. .

Therefore, in recent years, it is a situation to actively regulate the direct taking of the mobile phone while driving the vehicle, in consideration of this, hands-free device for making a call of the mobile phone in the vehicle has been proposed and widely spread.

Such a hands-free device is generally supplied with a vehicle power and used as an operating power, and an appropriate mounting structure including a magnet for mounting a mobile phone is formed on the front thereof, and the power of the cigarette lighter is used to charge the operating power of the mobile phone and the battery. The charging connector applied as a power supply for speech is provided, and the call voice connector is connected to the call voice input / output port of the mobile phone so that the reproducing output of the call voice and the call voice to be transmitted are provided, and by the call voice connector A speaker for reproducing a call voice received from a microphone and a microphone for inputting a call voice to be delivered to a mobile phone are provided, and an earphone / microphone connection jack is provided for earphone / microphone to be communicated by a secret call function.

Therefore, when the hands-free device is used, the call voice input through the microphone while the call is received is transferred to the mobile phone through the call voice connector and the call voice is transmitted from the mobile phone to the other party. When the call voice of the other party reached is delivered to the hands-free device through the call-voice connector, the voice is reproduced through the speaker. Thus, when the hands-free device is used, the call by the mobile phone can be made without taking the mobile phone directly while the vehicle is in operation. It becomes possible.

However, in the case of the conventional hands-free, since the main body and the microphone are formed integrally, there is a high possibility that an echo is generated, and in terms of design, many restrictions are applied. That is, when using a wired microphone, the processing of the microphone wire is a problem, and when using a wireless headset, there is a problem that the user is reluctant to attach to the ear.

On the other hand, most mobile phones used in Korea use the 3-pole jack for voice signals, and all hands-free are designed for the 3-pole jack. However, in the case of mobile phones used abroad, the frequency of using 4-pole jacks is increasing. Accordingly, the conventional hands-free is not a problem to use in Korea, but in the case of overseas export models, the hands-free for the 3-pole jack and the hands-free for the 4-pole jack are used. There was a problem that the inconvenience of having to produce separately.

In addition, conventionally, handsfree has been produced in three types: wireless earphone handsfree, CLA integrated handsfree, and dash board integrated handsfree. However, from the consumer's point of view, there was a problem that only one product can be selected from the three types of hands-free.

The technical problem to be achieved in the present invention is to eliminate the problems of conventional hands-free design and microphone line processing, to eliminate the hassle of wearing a wireless headset, and to use a simple operation or to separate the jack separately, so that the domestic and foreign three-pole and It can be used for most mobile phones using 4-pole jack, and by attaching and detaching the CLA part, it can be used as CLA integrated type and dash board integrated type. It is to provide hands free which can be used simultaneously.
