Our fixed line telephones are easy to use, and some even allow personalised settings: you decide the volume of the handset and you can even boost the sound further whilst on a call to ensure you hear every word.
These advanced and practical telephones are also a means of reassuring oneself with large, well-spaced buttons, visual ring indicators and photo memories.
#Handsfree headset for landline series#
Here's my question: How does the Western Electric 500 series, for example, provide the audio feedback from the mouthpiece to the earpiece? Is the circuitry in the cradle portion of the phone? Can the circuitry or components be isolated so that one could create an adapter that would allow you to plug a cell phone into a 500 series handset, or even the base, and get the audio feedback to the earpiece? Thanks, Hope you can read this OK.The landline phones have been designed by Doro to meet seniors’ various needs as well as providing additional comfort for communication in everyday life. I was excited again to see that the connecting cord to the handset had the old fashioned modular connector on it, and that it would fit into the ATT handset! So I tried, but no luck. I bought one, but the sound quality is digital, and there is no feedback to the earpiece. It does! I was very excited to find there are a few "retro" handsets on the market for cell phones. I thought I might be remembering better than it was, so I bought an old ATT princess phone to see if it sounded as good as I remembered it. The quality of the conversation is definately enhanced by this feedback, and also by the better audio quality of the analog technology of older phones. (If you could hear your own voice, no one would shout into the mouthpiece, since you would be shouting into your own ear!) This is annoying in restaurants, and in my living room. I am convinced that the lack of this characteristic contributes to the annoying occurance of people raising their voices and shouting into their cell phones. I am interested in a characteristic of older (102 to 500 series) ATT and Western Electric phones, namely that when you talk on those phones, you can hear your own voice. The white microphone wire comes in from the right (the side toward the cell phone) and dead ends at the microphone PCB. The bare return wire, which is shared by both speakers and the microphone, is connected to a ground plane on the small PCB and passes up to the speakers. Note how the red and green wires that go to the ear bud speakers pass directly through the microphone printed circuit board (PCB). As in the first image, the speakers are on the left, and the connection to the cell phone is on the right. The second image is a close-up of the "opened up" microphone enclosure, showing the identified wires. Figure 3 shows a microphone enclosure both "as built" and opened up. This will show you the wires and their functions. If you can, the next step is to open the microphone enclosure on your handsfree headset. If not, you will have to use this procedure as a guide and figure yours out. If your headset is similar to the one Im using in this example, youre in luck. Since each headset is different, there is no one best approach. What we need to do now is identify the wires in the handsfree headset cord. The trick is to connect together the correct wires. We are going to do this by cutting the plug off the modern handsfree headset and connecting it to the end of the coiled telephone cord. We are simply going to exchange the microphone and speaker in the old telephone handset for the microphone and one of the speakers in the modern handsfree headset. Cell phone handsfree headsets also contain a microphone and one (or sometimes two) speakers.
