Abstract: An improved hands-free speaker telephone designed to provide high-quality sound in a relatively small instrument, while at the same time avoiding acoustic shock to a user pressing the device too closely to an ear. If a speakerphone is mistaken for an ordinary portable or cellular phone, or simply out of misguided habit, a user may intentionally or inadvertently press the speaker against an ear. This action may subject the ear to an overly-loud audio event if the speaker begins producing sound, as hands-free speakerphone speakers are typically set to a much higher volume than those of ordinary phones. The effect, which is sometimes referred to as ‘acoustic shock’, is worsened significantly where the user actually succeeds in sealing the phone around the ear, as commonly (and harmlessly) occurs with standard (personal) phones. To avoid this undesirable phenomenon, the hands-free speakerphone is provided with a seal-proof speaker configuration.
