Dear,

Our ctm want to add the squeaking restraining function to their speaker. Could you help to check if TI have this solution? Thanks!

    Sundy,

    I do not follow your request. Is this a feature you have seen in another device or do you have any more information?

    Regards,

    Hi Sundy,
    As Adam mentioned above, you need to provide more detailed info about this application, then we could give out the appropriate recommendation. e.g. PVCC, Speaker resistance, Output power, digital or analog input.... What is the frequency response you want?
    Most of our digital input AMP has EQ fucntion, which can make the frequency response that you want.
    Best regards,

    Hi Shawn,

    When we use a normal walkitalki, there maybe has balabala/wuwu noise from the speaker. Now we want to find a solution to eleminate this noise. There is no reference part# now. Thank you.

    Hi Sundy,
    If the AMP device in your walkitalki application is from TI, the noise is not expected. Did you perform FFT on the output signal on the speakers? How much is the frequency components of noise? Knowing this helps you to find where the noise is from.
