1. Field of the Invention
This invention relates generally to telecommunications. More particularly, it relates to an audio accessory for a wireless phone.
2. Background of the Related Art
Wireless phones today have the ability to provide very high sound quality and are often used as music players. Conventional wireless phones include one internal speaker for placement against the ear of a user (and sometimes an additional two internal speakers for rudimentary stereo output), and a microphone for picking up voice from the user. Many wireless phones are sold with separately packaged ear buds (and sometimes ear buds with a microphone) to plug into a phono jack on the wireless phone, bypassing an internal speaker, to enjoy personal audio output by their wireless phone. Ear buds are presumably expected to be carried in a clothing pocket, purse, etc. when not in use. In some cases a pouch is provided for a wireless phone to be stored together with a set of ear buds.
Some conventional ear buds include a microphone, permitting use of the wireless phone as a phone via wired ear buds. Wireless earpiece and microphone devices are also known, communicating with the wireless phone via a piconet connection such as BLUETOOTH™. Some wireless auditory devices come with a case for storing the wireless auditory device, sometimes including a built-in recharge port (e.g., Plantronics Discovery 975). Wireless phones are suspected by some to emit small levels of radiation. Some experts believe that these levels of radiation may be harmful, while many if not most do not. Though not all experts agree if mobile phones can cause long-term, permanent damage, most generally agree that keeping a wireless phone away from the user's body, especially away from their head and ears, would diminish any possible risk of harm from mobile phone radiation if it exists.
In accordance with the principles of the present invention, a wireless phone audio system comprises an audio driver, and an internal speaker. An integrated, detachable ear bud physically attaches to a case of an associated wireless phone. A proximity sensor directs audio output from the audio driver to the integrated, detachable ear bud when the integrated, detachable ear bud is physically detached from the case of the associated wireless phone.
Features and advantages of the present invention will become apparent to those skilled in the art from the following description with reference to the drawings, in which:
The present inventors have appreciated that an ear bud, a pair of ear buds, or ear buds including a microphone, are often misplaced, separated from the wireless phone for which they are intended for use with, and/or simply lost. The present invention provides an integrated, detachable ear bud system that is integrated and attached to an associated wireless phone.
In certain embodiments the present invention provides an integrated, detachable, attached auditory device that is physically connected to its associated wireless phone via an extendable and retractable electrical cord, and integrated into the case of the associated wireless phone. By integrating the integrated, detachable ear buds into the case of the wireless phone itself, the integrated, detachable ear buds are forcibly kept with the wireless phone even when not in use, preventing misplacement, loss, or even inadvertent separation from the wireless device.
In particular, as shown in
Any suitable plastic or metal releasable latch that catches when the integrated, detachable ear bud 100a is pushed into its attached home position may be implemented. The releasable latch may be released blindly with suitable separation pressure applied to separate or detach the integrated, detachable ear bud 100a from the wireless phone 110a. Alternatively the releasable latch may be released when an associated button on the case of the wireless phone 110a is pressed or otherwise activated. The release latch may alternatively be software activated with an electrical solenoid, magnet, or the like. The integrated, detachable ear buds 100a may be latched with a suitable rare earth magnet mounted within the case of the wireless phone 110a and/or within the ear bud 100a.
In the embodiment of the integrated, detachable ear bud device shown in
The retractable, integrated, detachable audio system can be comprised of a single ear bud (e.g., suitable for listening to radio, etc.), or of a pair of ear buds (e.g., left-side and right-side ear buds) suitable for higher-end audio applications (e.g., music entertainment, movies, etc.)
Preferably the wireless phone 110a includes a home sensor switch that activates internal speaker(s) (and deactivates the speaker within the ear bud 100a) when the integrated, detachable ear bud 110a is in an attached home position attached to the wireless phone 110a, and deactivates internal speaker(s) (and activates audio to the ear bud 100a) when the integrated, detachable ear bud 100a is removed or detached from its attached home position. The home sensor switch may be a physical switch, or an inductive sensor switch.
In disclosed embodiments, each integrated, detachable ear bud 100a is preferably integrated into the case of its associated wireless phone 110a, e.g., integrated into the overall shape of the wireless phone 110a. For instance, the integrated, detachable ear bud 100a may be shaped to fill out a portion of the corner, side, or top edge of the case of the wireless phone 110a.
Integrated, detachable ear buds assure convenience, availability, and compatibility in an audio experience with respect to an associated wireless device 110a. Integrated, detachable ear buds also provide a hardened interface between a wireless phone 110a and an ear-mounted auditory component 100a via inclusion of an extendable/retractable audio cord 120a between the integrated, detachable ear bud 100a and its associated wireless device 110a.

Ideally, separation of either integrated, detachable ear bud 200L, 200R from the case of the associated wireless device 210a causes audio switching between an associated internal speaker (or speakers) 278L, 278R of the wireless phone to the integrated, detachable ear bud 200L, 200R. For instance, when a left-side integrated, detachable ear bud 200L is separated from the case of the wireless phone 210a, audio that was previously routed to a left-side internal speaker 278L may be re-routed to the detached left-side integrated, detachable ear bud 200L. In another embodiment, whenever one integrated, detachable ear bud 200L or 200R is removed, all audio to any (if just one) or both internal speakers 278L, 278R (e.g., left-side and right-side audio) is re-routed to the detached integrated, detachable ear buds 200L, 200R.

The present inventors have appreciated that hardwired, integrated, detachable ear buds provide a greater sound quality than a wireless headset (e.g., a BLUETOOTH™ ear bud and microphone.) However, if wireless audio is acceptable,
In particular, the embodiment of
In disclosed embodiments the wireless integrated, detachable ear bud 500a includes an internal rechargeable battery. The internal rechargeable battery may in certain low-cost applications instead by a non-rechargeable battery and occasionally replaced by the user.
The rechargeable battery of the wireless integrated, detachable ear bud 500a preferably is recharged by power from the wireless phone 510a when the integrated, detachable ear bud 500a is plugged into its attached, home position on the wireless phone 510a. To conserve battery power within the wireless phone 510a it is preferred that the recharge circuit that recharges the integrated, detachable ear bud 500a is activated to recharge the internal rechargeable battery of the integrated, detachable ear bud 500a only when the wireless phone 510a itself is being recharged or otherwise powered from an external power source external to the wireless phone 510a.
Compatibility between the wireless phone 510a and its associated integrated, detachable ear bud 500a is assured because the integrated, detachable ear bud 500a is integrated into, and detachably attached to, the wireless phone 510a itself. Conventional ‘pairing’ may be avoided or simplified as pairing information may be presumed by the wireless phone 510a when establishing its Bluetooth™ connection with the integrated, detachable ear bud 500a. However, even if ‘pairing’ is nevertheless required before the integrated, detachable wireless ear bud 500a may be fully activated, full conventional Bluetooth™ pairing may be accomplished to ensure that the integrated, detached ear bud 500a is readily available.
As shown in
Ideally the charge to the recharge ports 760L, 760R is activated when the wireless phone 610a is itself connected to an external recharge power supply. However, the integrated, detachable, wireless ear buds 700L, 700R may be recharged by the internal main battery of the wireless phone 610a. However, if such battery-to-battery recharge is activated, it is preferred that such battery-to-battery recharge be disabled when the remaining power in the main battery of the wireless phone 610a drops below a given threshold, e.g., below 10%, at which time the recharge ports 760L, 760R connected to the electrical connectors 750L, 750R of the integrated, detachable, wireless ear buds 700L, 700R are preferably turned off to conserve battery power.
The recharge ports 760L, 760R (and matching electrical connectors 750L, 750R) may be of any suitable connector type, including, e.g., a straight power jack, a micro USB, etc.

In particular, as shown in
The integrated, detachable wireless jawbone ear bud 900a preferably includes an internal rechargeable battery that can be recharged through the recharge port 960 when in an attached, home position on the wireless phone 510a. Alternatively, the integrated, detachable wireless jawbone ear bud 900a may be recharged on a matching remote recharge port separate from the wireless phone 510a. Alternatively, the integrated, detachable wireless jawbone ear bud includes a rechargeable battery that can be recharged when attached to an thus plugged into the wireless phone 510a while the wireless phone 510a too is recharging.
Unique left/right physical keying may be included between the integrated, detachable wireless ear buds 600L & 600R, or 700L & 700R, or integrated, detachable wireless jawbone earpiece/microphone to differentiate between a left-side and a right-side. Unique left/right physical keying would prevent a left-side ear bud from attaching to a designated right-side-associated portion of the wireless phone, and vice versa. In this way left-side audio may be consistently provided to what is expected to be a left ear of a user of the mobile phone, and vice versa for the right-side.
The present invention anticipates accommodation for advancement of audio devices by enabling replacement of the integrated, detachable ear buds (or wireless jawbone) for repair or upgrade. For instance, in one embodiment, an extendable/retractable cord of the integrated, detachable ear buds is removable by release of a set screw, or by release of a latch accessed through a small opening in the case of the wireless phone (e.g. using the end of a small paper clip.) Preferably, since integrated with a given model wireless phone, the integrated, detachable ear bud(s) are manufactured by an original equipment manufacturer (OEM) of the wireless phone itself.
The invention addresses a number of problems related to health, convenience, and performance of wireless accessories provided by the current marketplace. Any individual using a mobile phone with an integrated, detachable ear bud, whether for conversation or their listening pleasure, benefits.
A significant benefit from the use of an integrated, detachable ear bud system in accordance with the principles of the present invention is that it enables a wireless phone to provide a radiation-safe, secure, superior sound experience as the ear buds may be designed specifically to the needs of the attached wireless phone. Another benefit from the use of integrated, detachable ear buds is that it provides significant separation between an operating wireless phone and the head of a user, thereby keeping any possible harmful radio wave radiation even more safely away from the head of a user.
While the invention has been described with reference to the exemplary embodiments thereof, those skilled in the art will be able to make various modifications to the described embodiments of the invention without departing from the true spirit and scope of the invention.
