Description

Hands-free device for mobile phone {HANDS-FREE DEVICE FOR MOBILE TELEPHONES}

Currently hands-free devices for mobile phones have a length of cord that connects the phone to the talker and earphones, allowing the user to talk to the mobile phone without using their hands. This is especially useful when driving a car.

However, when not using a mobile phone, the code can sometimes get in the way of many things. To overcome this, many users wind their cords on their mobile phones so that they don't interfere with other objects. Then, when you need a hands-free device, you need to unwrap the cord before using the handset and earphones.

In addition, the use of 'hands-free' mobile phones outside the vehicle is becoming increasingly popular. This is due to the convenience of being able to use the hand for other work without holding the phone, especially when the transceiver of the phone is placed near the human brain for a long time, causing the electromagnetic waves from the transceiver to cause tumors such as cancer.

This problem confirms the need for a device that offers the advantages of a hands-free device for current mobile phones while eliminating the obstructions when the phone is not in use.

Brief description of the invention

An object of the present invention is to provide a hands-free device for a mobile telephone having a talker and earphone separate from the talker and earphone of the mobile telephone.

In a broad form, the present invention provides a phone attachment device having a microphone and earphone at the end thereof and comprising a cord suitable for rewinding into the housing by rewinding means. Preferably, the housing is embodied in a separate case suitable for plugging into a socket provided in the phone case. Alternatively but also preferably, the housing is integrally formed in the phone case. Also optionally but also preferably, the housing is embodied in a separate case suitable for connection to the telephone by a wireless communication channel. In a preferred embodiment, the telephone is a mobile telephone. Preferably, the rewinding means is a spring tension device or another device that is mechanically biased. In this preferred form, the rewinding means rewinds the cord in the same way as a spool. Also in this preferred form, the rewinding means comprise locking means for preventing the cord from winding by itself. In an alternative preferred form, the rewinding means is driven by an electric motor or the like. Preferably, the microphone and earphone are suitable for being accommodated in the device or the telephone, or for hanging on or otherwise hanging on the device or the telephone.

The present invention relates to an accessory that enables 'hands-free' use of a mobile phone. Specifically, the present invention relates to a personal portable hands-free device for a mobile phone using a rewindable cord, and also to a wireless personal portable hands-free device for a mobile phone.

The invention can be more fully understood from the detailed description of the preferred but not limiting embodiment, which is described in conjunction with the following figures.

1 is a view showing a preferred embodiment of the present invention,

2 is a view showing a more preferred embodiment of the present invention,

3 illustrates a more preferred embodiment of the present invention.

Throughout the drawings, like reference numerals are used to indicate similar characteristics unless clearly indicated otherwise.

As shown in Fig. 1, the rewindable hands-free device 1 for a mobile phone embodied by attaching a mobile phone is composed of a spring tension device 2 which rewinds the cord when the locking device 5 is released. It is. The cord and spring arrangement is attached to a fixture 3 which provides suitable code storage means and allows the cord to be secured when the desired length of cord emerges from the device 1. The case for the accessory of the rewindable hands-free device 1 for a mobile phone also includes an electronic circuit 6 necessary for the use of an existing mobile phone. The hands-free device 1 is fixed to the mobile telephone by mechanical means such as a fixing pin 7 suitable for some type of mobile telephone accessory port.

Another preferred embodiment of the present invention is shown in FIG. In this embodiment, the rewinding device is integrally formed in the case of the mobile telephone 8. After the cord is pulled out, the lock button 5 can be fixed at a desired length. Then, the talker 9, earphone 10, and cord lock clip 11 operate according to the conventional method of hands-free for a mobile phone. When the user wants to rewind the cord, the potential energy stored in the spring device 2 is used to pull the cord into the telephone. The telephone may be provided with a recess for the fixing device, or may be provided with a housing for accommodating the earphone or the talker in such a way that the cord is not loosely attached to the telephone.

Another preferred embodiment of the present invention is shown in FIG. In this embodiment, the talker and earphone are not electrically connected to the mobile telephone. By means of the transmitting device 12 attached to or integrally formed in the mobile telephone, the electromagnetic signal 13 is received at the antenna wire 14. The low power transceiver 15 integrally formed in the transmitter and shown in FIG. 3 enables wireless communication with the mobile phone within a few meters of distance. Yet another preferred embodiment incorporates a talker and earphone into the headphones, which are more comfortable to use for a long time and easier to write and take off.

Other various changes and modifications of the present invention will be apparent to those skilled in the art. All such changes and modifications fall within the scope of the invention as broadly described and claimed herein.
