Speakerphone feature for a wireless handset
First Claim
Patent Images
1. A wireless handset comprising:
- a protective housing;
receiving circuitry configured to receive RF signals and output sound signals;
an earpiece speaker connected to receive some of the sound signals from the receiving circuitry and positioned to project corresponding sound waves through a first surface of the housing;
a second speaker connected to receive others of the sound signals from the receiving circuitry and positioned to project corresponding sound waves through a second surface opposing the first surface, where the second speaker operates at a higher volume than the earpiece speaker; and
wherein the second surface is shaped so that, when the second surface rests against a rigid surface, the sound waves projecting from the second speaker through the second surface strike the rigid surface at an acute angle.

Abstract
A wireless speakerphone is designed to prevent damage to a user'"'"'s ear when the phone is placed against the user'"'"'s ear during speakerphone operation. The phone includes a second speaker, or second speaker, embedded behind its rear surface. The rear surface is shaped so that, when resting against a rigid surface such as a desktop or tabletop, the rear surface and the rigid surface together form a waveguide that directs sound waves from the second speaker into the surrounding room.

9. A wireless speakerphone comprising:
-
a protective housing;
transceiving circuitry configured to send and receive RF signals over a communication channel and convert incoming RF signals into sound signals;
a microphone;
an earpiece speaker connected to receive some of the sound signals from the transceiving circuitry and positioned to project corresponding sound waves through a first surface of the housing;
a second speaker connected to receive others of the sound signals from the transceiving circuitry and positioned to project corresponding sound waves through a second surface opposing the first surface, where the second speaker operates at a higher volume than the earpiece speaker; and
wherein the second surface is shaped so that, when the second surface rests against a rigid surface, the sound waves projecting from the second speaker through the second surface strike the rigid surface at an acute angle. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method comprising:
-
receiving RF signals;
recovering sound signals from the RF signals;
delivering some of the sound signals to an earpiece speaker in a telephone handset;
delivering others of the sound signals to a second speaker in the telephone handset;
for the sound signals delivered to the earpiece speaker, projecting the sound signals through a first surface of the handset; and
for the sound signals delivered to the second speaker, projecting the sound signals through a second surface opposing the first surface so that, when the second surface rests against a rigid surface, the sound waves projecting from the second speaker through the second surface strike the rigid surface at an acute angle. - View Dependent Claims (18, 19)
