DETAILED DESCRIPTION OF THE DRAWINGS
Systems, methods, and apparatuses for adjusting the audio setting of a communications headset are disclosed. The following description is presented to enable an ordinarily skilled person in the art to make and use the invention. Descriptions of specific embodiments and applications are provided only as examples and various modifications will be readily apparent to those skilled in the art. The general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the invention. Thus, the present invention is to be accorded the widest scope encompassing numerous alternatives, modifications and equivalents consistent with the principles and features disclosed herein. For the purpose of clarity, material that is known in the technical fields related to the invention have not been described in detail so as not to unnecessarily obscure the present invention.
Monaural headsets have their limitations with respect to audio quality because the audio settings for the best audio quality for an over the ear wearing style are not the same as for a headband with an ear cushion wearing style. Therefore, users of such monaural headsets only receive the best audio quality for one of the two wearing styles. As a result, improved apparatuses and methods for changing the audio settings from an over the ear wearing style to a headband with ear cushion wearing style or vice versa are needed.
FIG. 1 illustrates a communications device 100, according to one embodiment of the invention. The communications device 100 comprises a body 105, a boom 110, a microphone 115, a speaker port 120 and an attachment post 125.
The communications device 100 provides audio signals to a user's ear. The communications device 100 includes an audio driver (not shown) to convert an audio signal, received via cord or wirelessly, to an audible output via the speaker port 120. The communications device also includes a boom 110 and a microphone 115 located in the tip of the boom 110. The microphone 115 may comprise a noise cancelling microphone, for example. The communications device 100 also includes an attachment post 125 for attaching the communication device 100 to a headband (such as headband 300 shown in FIG. 3A) or an ear bud and ear loop (such as ear bud 405 and ear loop 415 shown in FIG. 4). A sensor 205 (see FIG. 2) located in the communications device 100 can change the audio setting to a headband mode when the headband 300 is attached or to a non-headband mode when the headband 300 is detached.
FIG. 2 shows a cut away view of the communications device 100, according to one embodiment of the invention. The communications device 100 comprises a sensor 205 and a speaker 210. Also shown is a C magnet 215 which is located in the headband boss of the headband 300 (not shown).
The sensor 205 may be coupled to a printed circuit board 208 which includes a processor (such as processor 600 shown in FIG. 6) for receiving signals from the sensor 205.
The sensor 205 may be a reed switch or a Hall Effect Sensor which is a transducer that varies its output voltage in response to changes in magnetic field, according to an embodiment of the invention.
The C magnet 215 allows the communications device 100 to rotate 300 degrees while attached to the headband 300 and not have the sensor 205 go out of range of the magnet 215. A ring magnet or a number of cube magnets arranged in a loop may be placed in the headband boss of the headband to accomplish a similar result, according to an embodiment of the invention. With one of these types of magnets used in the headband boss, the sensor 205 remains at a detectable distance from the magnet 215 regardless of the rotational position of the communication device 100.
FIG. 3A shows the communication device 100 and a headband 300, according to one embodiment of the invention. The headband 300 comprises an ear cushion 305, a pad 310, a headband attachment recess 315 and a magnet 215 (not shown, See FIG. 2).
The attachment post 125 of the communication device 100 can be attached to the headband 300 at the headband attachment recess 315. The attachment post 125 attaches to the headband attachment recess 315 of the headband 300 by a bayonet locking mechanism, according to an embodiment of the invention. Once the communications device 100 is attached to the headband 300, a sensor (such as sensor 205 shown in FIG. 2) located in the communications device 100 senses a magnet (such as magnet 215 shown in FIG. 2) located in the headband 300 and signals a processor (such as processor 600 shown in FIG. 6) coupled to the communications device 100 to adjust an audio setting of the communications device 100 to a headband mode. The headband mode audio setting is a setting optimized for the headband wearing style.
Once attached together as shown in FIGS. 3B and 3C, the communications device 100 and headband 300 act as a conventional headset with a headband and fits over a user's ear and head. The pad 310 is biased towards the ear cushion 305 and allows the communications device 100 and headband 300 to be supported on a user's ear and head. While attached in the headband attachment recess 315, the attachment post 125 allows the communications device 100 to pivot approximately 300 degrees so the user may find the most comfortable wearing position and still maintain a correct boom 110 orientation, according to an embodiment of the invention.
FIG. 4 provides an exploded view of the communications device 100, an ear bud 405, an ear bud attachment recess 410 and an ear loop 415, according to one embodiment of the invention.
The ear loop 415 which comprises an ear loop attachment point 420 attaches to the attachment post 125 of the communication device 100 at the ear loop attachment point 420. Once the ear loop 415 is attached to the communications device 100, the ear bud 405 is attached to the attachment post 125 at the ear bud attachment recess 410. The attachment post 125 attaches to the ear bud attachment recess 410 and securely holds the ear loop 415 and ear bud 405 in place by a bayonet-type locking mechanism. Other locking mechanisms could be employed within the spirit of the invention.
Once the communications device 100 is converted from being attached to the headband 300 to the ear loop 415 and the ear bud 405, the sensor 205 (See FIG. 2) no longer senses a magnet (see the magnet 215 shown in FIG. 2) located in the headband 300 and signals the processor coupled to the communications device 100 to adjust the audio setting of the communications device 100 to a non-headband mode. The non-headband mode audio setting is a setting optimized for the ear bud 405 and ear loop 415 wearing style.
Once attached together as shown in FIG. 5, the communications device 100, ear loop 415 and ear bud 405 acts as a conventional headset with an ear loop and fits over a user's ear. The ear loop 415 allows the communications device 100 with the ear bud 405 to be supported on a user's ear. While attached in the ear bud attachment recess 410, the attachment post 125 allows the communications device 100 to pivot approximately 300 degrees so the user may find the most comfortable wearing position and still maintain a correct boom 110 orientation, according to an embodiment of the invention.
