`
`FIELD OF INVENTION
`0009. The present invention can relate to headsets. More
`particularly, the present invention can relate to headsets for
`communicating with an electronic device.
`
`BACKGROUND OF THE INVENTION
`0010 Headsets for providing hands-free communications
`are known in the art. Such headsets typically can be used in
`conjunction with a cellular telephone or a computer (e.g.,
`Voice over IP). Some existing headsets include a microphone,
`
`a speaker (also referred to as a receiver), electronics for con
`trolling the headset and communicating with another device
`(e.g., a cellular telephone), a battery and a connector for
`re-charging the battery.
`0011. There are many aspects involved in the design of
`headsets. For example, the size and weight of headsets can be
`key issues because of how they typically mount to a user's ear.
`A heavy or large headset can pull on a user's ear, creating an
`uncomfortable fit. The shape of headset earpieces (e.g., ear
`buds) may also be an important design consideration to take
`into account as it is desirable for earpieces to fit comfortably
`in, on, or over a wide range of different sizes and shapes of
`CaS.
`0012. Additionally, the acoustic performance of headsets,
`Such as receiver Sound generation quality and microphone
`Sound reception quality (e.g., ability to pick up a user's voice
`without undue background noise), can be important design
`considerations. Achieving desired receiver and microphone
`acoustic performance can become increasingly difficult as the
`size of a headset decreases.
`0013 Another example of an important design consider
`ation can be the user interface of a headset. It may be desirable
`for a user interface to be intuitive for a first-time user, yet
`convenient for an experienced user.
`0014) Aesthetics may be yet another important, design
`consideration for headsets.
`0015. Further still, ease of manufacturing headsets can be
`another design consideration. For example, it can be desirable
`to design aheadset that can be mass produced in an affordable
`fashion.
`0016. In view of the foregoing, there is a need for an
`improved headset that addresses one or more of the above
`identified considerations.
`
`SUMMARY OF THE INVENTION
`
`0017. In accordance with one embodiment of the present
`invention, an electronic device is provided. The electronic
`device can include a housing and a connector assembly
`coupled to the housing. The connector assembly can include
`a microphone port. The electronic device can include a micro
`phone mounted within the housing and a channel that fluidi
`cally couples the microphone to the microphone port.
`0018. In accordance with another embodiment of the
`present invention, a joint connector and microphone assem
`bly is provided. The assembly can include a microphone with
`a top Surface and side Surfaces. The top surface of the micro
`phone can include a microphone input. The assembly can

`
`DETAILED DESCRIPTION OF THE INVENTION
`0091. The present invention relates to headsets and meth
`ods for manufacturing the same. Headsets are communication
`devices that are worn on a user's head in order to allow hands
`free data and/or voice communication with a host device Such
`as a computer, phone handset, cellular phone, an automobile
`and/or the like. Headsets can include one or more speakers (in
`proximity to one or both ears) for audio output and/or one or
`more microphones for audio input.
`0092 Headsets can come in a variety of form factors or
`shapes. In some cases, headsets can be embodied as an ear
`piece that serves as the primary Support mechanism for wear
`ing the headset. For example the headset may be Supported on
`the head by an earpiece worn over or in the ear. Alternatively,
`the headset may be supported by a frame or band that fits on
`or over the user's head. The headset may include a fixed or
`movable boom that places the microphone closer to the user's
`mouth (wraps around the face). Alternatively, the headset
`may be boomless Such that the microphone is integrated with
`the earpiece thereby forming a more compact device (e.g.,
`Smaller, lighter, more aesthetically pleasing, etc.).
`0093. According to one aspect of the invention, the head
`set can be embodied as a small compact unit including a
`primary housing and an earbud member extending therefrom.
`The earbud member may be attached to or integrally formed
`with the primary housing. Various components can be placed
`at the surface of or within the confines of the earbud member
`and the primary housing. In fact, both of them can include one
`or more components depending on the needs of the device.
`The components contained within each of these can be widely
`varied. Examples of operational components can include
`speakers, microphones, antennas, connectors, buttons, dis
`plays, indicators, battery, and associated processors, control
`lers and circuitry. Generally, the earbud member includes at
`least a speaker while the primary housing includes at least a
`microphone (although this is not a requirement). Depending
`on their size, each of these members can include additional
`components of the headset. In one embodiment, the primary
`housing includes an antenna, user interface button, indicator
`or display (e.g., LEDs), battery, microphone, and/or a con
`nector along with any accompanying circuitry while a
`speaker, a processor, and its accompanying circuitry can be
`located in the earbud. The button can be located on one end of
`the main housing. A user can interface with this button to
`perform various functions (e.g., terminating calls).

`
`0094. The shape and size and orientation of the earbud
`member and primary housing can be widely varied. In one
`embodiment, the earbud member is configured for insertion
`into the ear Such that it supports the remaining portions of the
`headset (e.g., primary housing) proximate the user's head. In
`one embodiment, the primary housing can be configured as a
`longitudinal member (e.g., a tube). In one example, an earbud
`member, which contains a speaker, perpendicularly protrudes
`away from one end of a longitudinally extending primary
`housing, which includes a microphone at an opposite end of
`the longitudinally extending primary housing. Furthermore,
`the earbud member can expand outwardly and then inwardly
`from a neck portion that couples to the primary housing in
`order to form a bud that fits into an ear.
`0095. The primary housing can include a tube that forms a
`housing and receives internal components through an open
`end. The tube can be manufactured using one of several
`processes in order to reduce costs and increase speed and
`efficiency. In one embodiment, the tube can be manufactured
`to include features on the inner surface of the tube for Sup
`porting electronic components of the headset. Processes for
`creating Such a tube can include applying a die and stamp to
`an extruded tube, single or double impact extrusion, or a
`progressive deep draw process.
`0096. The headset can include a hollow neck between the
`earbud and the primary housing in order to allow electrical
`wires to connect sets of discrete electronics disposed within
`the earbud and primary housing. In one embodiment, dual
`threaded inserts can be used to structurally reinforce the hol
`low neck without adding size to the device.
`0097 Small compact headsets have limited surface area
`for placing components. Therefore, one aspect of the inven
`tion relates to integrating multiple components into the same
`surface area of the headset in order to help form a small
`compact headset. Put another way, multiple components can
`be built into the same location on the headset in order to
`achieve the desired level of functionality without impacting a
`desired small size of the headset. The components may for
`example be selected from connectors, microphones, speak
`ers, buttons, indicators, displays and/or the like. In one
`embodiment, an antenna and a button function at the same
`location of the headset. In another embodiment, a micro
`phone and connector function at the same location of the
`headset. Other embodiments can also be realized. For
`example, a button can function at the same location of a
`speaker (e.g., at an earbud) or an indicator can function at the
