Abstract
The earphone 14 of a personal handsfree device for a radiotelephone is coupled to a user's ear by means of a hollow sound collection means 10, an acoustic tube 11 and an earpiece 12. The tube may include flexible joints (19, fig 7). In an alternative embodiment the earphone (14, fig 4) and microphone (16, fig 4) are built into an adaptor (17, fig 4) connected to the body of the mobile telephone. In another embodiment (see figs 5, 6) the user's voice may be carried by a further acoustic tube lying beside or inside the first tube.
Description
<Desc/Clms Page number 1>
COMMUNICATIONS DEVICE PERSONAL HANDS FREE AUDIO INTERFACE This invention relates to a personal hands free audio interface for a communications device, such as a mobile phone.
Personal hands free headsets are well known communications device accessories, which allow the use of the communications device without the need to hold the body of the device to the user's ear, freeing up the user's hands. According to the present invention there is provided a sound transfer tube to collect the audio sound from a sound transducer, via a hollow sound collection device and transfer it to a hollow audio earpiece without the use of metallic radio frequency conducting materials. The sound transfer tube is long enough to keep all necessary metallic radio frequency conducting parts away from the user's head.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing in which: Figure 1 shows the personal hands free audio interface: Figure 2 illustrates the hollow audio earpiece (one shown in section) fitted with the sound transfer tube; Figure 3 shows sections of the hollow sound collection device and the sound transfer tube; Figure 4 shows alternative connector-mounted sound transducer and microphone; Figure 5 shows two sound transfer tubes in section mounted side by side;
<Desc/Clms Page number 2>
Figure 6 shows two sound transfer tubes in section, one mounted inside the other; and Figure 7 shows a swivel or flexible joint between the sound transfer tube and the hollow audio earpiece.
Referring to the drawings Figure 1 to 7, a hollow audio earpiece 12 is connected to a sound transfer tube 11. The sound transfer tube 11 is in turn connected to a hollow sound collection device 10 which collects audible sound from a sound transducer (e.g. speaker) 14. The device has a connecting cable 13, a microphone 16 and is attached to a communications device body 15 by a connector 17.
The hollow audio earpiece 12 is inserted into the ear and is provided with one or more holes to allow the audible sound to pass into the ear. The earpiece may be provided with a foam, fabric or similar cover for the comfort of the user. The length of the sound transfer tube 11 is such that the radio frequencies radiating from the sound transducer, microphone and connecting cable are positioned away from the user's head. The microphone 16 may be located on the sound tube 11 for support.
The sound collection device 10 can be made as a permanent attachment to the sound transducer 14 or be a retrofit attachment to fit existing personal hands free devices.
The hollow sound collection device 10 (see Figure 3) collects the audio sound from the sound transducer's resonating diaphragm (or cone) 18 and focuses it into the end of the sound transfer tube 11. The sound then passes along the sound transfer tube to the hollow audio earpiece and directly into the user's ear. The connecting cable 13 may be provided with screening and/or other RF suppression measures to further reduce transmitted radio frequency signals.
<Desc/Clms Page number 3>
For comfort and convenience, a swivel or flexible joint 19 (refer to Figure 7) may be used within the assembly of the hollow audio earpiece, sound transfer tube and/or sound collection device. This will enable the device to have greater freedom of movement without the hollow audio earpiece becoming dislodged from the user's ear during use.
The microphone 16 and sound transducer 14 may be both located in a common unit / housing assembly.
The sound transducer 14 may be housed in the connector 17 as an alternative to being connecting cable mounted. The sound transfer tube 11 will in this case be longer in order that the communications device body 15 can be sited at an appropriate distance from the user (See figure 4).
The sound transducer 14 and the microphone 16 may both be housed in the connector 17 (See figure 4).
The communications device body 15 may be provided with a sound transfer duct, which transfers the audio sound from its built in speaker to a port onto / into which the sound transfer tube 11 connects and is secured by means of an adapter.
This connection may be at any convenient location on the communications device's body.
The communications device body 15 may be provided with a sound transfer duct, which transfers the audio sound from its built in speaker to a port onto / into which the sound transfer tube 11 connects and is secured by means of an adapter. And in addition the users voice may be transmitted to a microphone built into the communications device in a similar way by tube. In this case a second sound transfer tube could connect the user's voice directly into the microphone, thus improving voice pickup or a common tube could be used for both microphone and sound transducer. These connection(s) may be located at any convenient location on the communications device's body. If two tubes are used they may be positioned / secured side by side (refer to figure 5) or may be located one inside
<Desc/Clms Page number 4>
the other (refer to Figure 6) to effectively form a single connection between the user and the communications device body.
The audio earpiece may include a boom-mounted support for the microphone sound transfer tube. The assembly may be attached to the user's head by a clip arrangement, which fits around and behind the ear to secure the earpiece into the user's ear, or by any other attachment method.
In a similar way the hollow audio earpiece and microphone ducts could be incorporated into a helmet, fashion (e.g. baseball cap) or any other headgear. Depending on the design of the helmet or headgear, a detachable connection between the helmet or headgear itself [incorporating sound duct(s)], and the remaining parts of the personal hands free audio interface would be positioned for convenience.
