Need Heaphone/Mic Amp Circuitry

Recommended Posts

Ok, first I have a set of turtle beach ear force x11 gaming headset with the following specs:


Headphones:
- 40mm diameter speakers with neodymium magnet
- Speaker Frequency Response: 30Hz - 20kHz, >120dB SPL @ 1kHz
- Condenser Microphone Frequency Response: 50Hz - 15kHz
- Cable length: 16 ft. (4.877m)
- Weight: 6.4 oz. (233g)

In-Line Amplifier:
- Headphone Amplifier: Stereo DC-coupled, 35mW/ch, THD <1%, Frequency Response: DC - 30kHz
- Mic mute switch
- XBOX controller 2.5mm input jack
- Maximum analog input level with volume control on maximum setting: 2Vpp (700mV rms)
- 3.5mm plug for mic output
- 3.5mm plug for line input
- Weight: 1.3 Oz (36g)
- USB connector for power (5VDC @ <50mA max)
- Dimensions: Height .5in (1.27cm), Width 2in (5.08cm), Depth .75in (1.905cm)

My idiot brother got ahold of my headset and not only ripped the wires loose from the controls output wires, but apperently also fried the controller... my question is, can anyone recommend circuitry to fix the mic and speakers?? Don't care about the controller port as I don't game online with xbox anyhow, so I only need the mic and speakers. I looked on project page, but since my knowlage of audio like this is non exhisting. any help is appreciated. Lucky for me the input side of wires is good, so I got a usb for power, mic plug and speaker plug. Meanwhile, going to try and see if I can locate scematics for the contoller.  I know I can just buy new set, but I don't have much cash lately, so fixing them better option for me. Thanks.

Joe

Most of the spec's for the headphones are absolutely useless. The frequency response spec's do not say plus and minus 30dB which is horrible or plus and minus 2dB which is pretty good. Who cares about the length of the cord and the weight?

The important spec for the ear speakers is the impedance that you can measure with a multimeter but you didn't.

If the circuit is modern then it uses tiny little parts that are difficult to solder and unsolder.

If you look around on ebay or amazon.com for "audio amplifier board 5 volts" you may find something that would be helpful. Like:

Icstation PM2038 2X5W stero audio amplifier board 5v USB powered adjustable volume. They are quite inexpensive.

Sorry I can not be more helpful.
