Abstract

The invention pertains to mobile telephones and can be used during telephone conversations while, for example, operating a mode of transportation. The universal hands-free unit for mobile telephones contains the main module containing a speaker and control electronics, a holder for the mobile telephone, a microphone, an attachment module, and a changeable connection module for electrical connection of the control electronics with the electrical circuits of the mobile telephone. The holder of the mobile telephone is constructed in the form of two plates oriented parallel to each other at a distance L which may be changed by moving at least one plate relative to the other plate with the help of a mechanism located in the body of the main module. A fixating bracket attached to each holding plate, each fixating bracket is made in the shape of a base with several parallel resilient fins.

Claims

1. A hands-free unit for a mobile telephone with a width S comprising

a mobile phone holder, comprising

two parallel plates separated by a distance L,

L being greater than S,

a main module elongated along the axis of the mobile telephone,

the main module comprising

a speaker positioned in the upper part of the main module,

a front surface comprising

a flat area in the lower part of the main module,

the flat area being located between the parallel plates,

the flat area being adjacent to a mobile phone attachment locus,

control electronics, and

a transference mechanism capable of changing L, two fixating brackets,

each fixating bracket attached to a surface of a respective plate facing another plate,

the height of each fixating bracket being at least H,

H being greater than 0.5 multiplied by (L-S)

each fixating bracket comprising

a base and

resilient fins parallel to each other,

the resilient fins being positioned at an angle α

to the base,

α

being greater than 80° and

less than 90°

,

the resilient fins being positioned at an angle β

to the surface of the flat area of the

front surface of the main module,

β

being greater than 80° and

less than 90°

,

a microphone,

an attachment module, and

a changeable connection module, the connection module being capable of coupling the control electronics with electric circuits of the mobile phone.

2. The hands-free unit of claim 1 wherein the height of each fixating bracket decreases in the direction towards the surface of the flat area in the lower part of the main module.

3. The hands-free unit of claim 1 wherein the height of each fixating bracket decreases in the direction towards the upper part of the main module.
