Receivers are small speakers used by many conventional portable electronic devices to produce sound. For example, the voice of a caller may be generated by a receiver of a conventional mobile phone. The receivers are attached to the device housing around the area in the device housing with the speaker hole. In this manner, receivers of conventional portable electronic devices project sound directly out of the speaker hole for listening by a user.
Given that the receivers are located behind the speaker hole of the device housing, the placement of the speaker holes for conventional portable electronic devices is constrained by the size and shape of the receiver. For example, the receiver is often pushed to the top of the device housing to make room for other components. As such, the speaker holes of many conventional portable electronic devices are located near the top of the device housing.
Conventional portable electronic devices with speaker holes located near the top of the device housing are generally uncomfortable to use given that the top edge of the device housing must be pressed into the user's ear. Additionally, the small distance between the speaker hole and the top of the device housing makes it more difficult for a user's ear to seal against the device housing around the speaker hole. As such, conventional portable electronic devices generally offer poor sound quality.
Back volume chambers are sometimes used in portable electronic devices to increase the sound quality of the receivers. The quality of the seal as well as the size and shape of the back volume chamber can affect the frequency bandwidth of the sound generated by the receiver. The back volume chambers of some conventional portable electronic devices are formed using sealant between walls of the device housing and other components (e.g., printed circuit boards). However, the seal created by the sealant often fails over time due to degradation of the sealant, relative movement between the printed circuit boards and the device housing, and the like. Additionally, the size and shape of the back volume chamber of conventional portable electronic devices is determined by the arrangement of the device housing and other components (e.g., printed circuit boards). Accordingly, the back volume chambers of conventional portable electronic devices offer limited improvement in sound quality.
Accordingly, a need exists for a receiver mounting for a portable electronic device which enables the speaker hole to be located farther from the top of edge of the portable electronic device housing. A need also exists for a receiver mounting which provides more flexibility on the location of the receiver within the portable electronic device housing. Additionally, a need exists for a receiver mounting which provides a more airtight back volume chamber for a receiver of a portable electronic device. Further, a need exists for a receiver mounting which provides more flexibility as to the size and shape of the back volume chamber for the receiver. Embodiments of the present invention provide novel solutions to these needs and others as described below.
Embodiments are directed to a speaker component for a portable electronic device which accepts a receiver and redirects the sound emitted from the receiver toward the speaker hole in the device housing. For example, the receiver may be oriented such that sound is directed away from the speaker hole to reduce the footprint of the receiver within the device housing, while a channel of the speaker component may redirect or port the sound to the speaker hole. In this manner, embodiments provide more flexibility for positioning of the speaker hole and the receiver with respect to the device housing. The speaker component may also have a self-contained back volume chamber adjoining the receiver which does not include portions of the device housing or other components of the portable electronic device, thereby improving the sound quality of the sound emitted from the receiver and providing more design flexibility as to the size and shape of the back volume chamber.
In one embodiment, a speaker component includes a receiver for generating sound in a first direction, the receiver for use in a portable electronic device. The speaker component also includes a channel disposed adjacent to the receiver, the channel for redirecting the sound in a second direction, wherein the first and second directions are different. The speaker component may further include a sealed chamber adjoining the receiver, the sealed chamber forming a back volume for the receiver. The speaker component may further include a first portion comprising a first cavity for accepting the receiver, the first portion further comprising the channel connected to the first cavity for enabling the sound to travel from the first cavity through the channel, a second portion comprising a second cavity, and an interstitial layer for physically coupling the first portion with the second portion, the interstitial layer further for creating a back volume for the receiver comprising the second cavity.
In another embodiment, a portable electronic device Includes a housing comprising a hole for emitting sound, a processor disposed within the housing, and a memory coupled to the processor and disposed within the housing. The portable electronic device also includes a speaker component operable to direct sound through the hole, the speaker component including a receiver for generating sound in a first direction and a channel disposed between the receiver and the hole, the channel for redirecting the sound in a second direction toward the hole, wherein the first and second directions are different.
In yet another embodiment, a portable electronic device includes a housing comprising a hole for emitting sound, a processor disposed within the housing, a memory coupled to the processor and disposed within the housing, and a display coupled with the housing. The portable electronic device also includes a speaker component operable to direct sound through the hole. The speaker component includes a receiver for generating sound in a first direction and a channel disposed between the receiver and the hole, the channel for redirecting the sound in a second direction toward the hole, wherein the first and second directions are approximately orthogonal. The speaker component also includes a seated chamber adjoining the receiver and forming a back volume for the receiver.
The present invention is illustrated by way of example, and not by way of limitation, in the figures of the accompanying drawings and in which like reference numerals refer to similar elements.
Reference will now be made In detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. While the present invention will be discussed in conjunction with the following embodiments, it will be understood that they are not intended to limit the present invention to these embodiments alone. On the contrary, the present invention is intended to cover alternatives, modifications, and equivalents which may be included with the spirit and scope of the present invention as defined by the appended claims. Furthermore, in the following detailed description of the present invention, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, embodiments of the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components, and circuits have not been described in detail so as not to unnecessarily obscure aspects of the present invention.
Embodiments of the present invention are directed to a speaker component or assembly (e.g., 100 of
The speaker component or assembly may also have a self-contained back volume chamber adjoining the receiver which does not include portions of the device housing or other components of the portable electronic device. For example, a cavity (e.g., cavity 135, cavity 124, etc.) within a portion of the speaker component (e.g., portion 130, portion 120, etc.) may adjoin the receiver and provide a sealed back volume chamber for the receiver. Accordingly, embodiments may improve the sound quality of the sound emitted from the receiver and offer more design flexibility (e.g., mechanical design flexibility, industrial design flexibility, etc.) since features of the back volume chamber (e.g., size, shape, location with respect to the receiver, etc.) may be varied independently of the housing and other components of the portable electronic device (e.g., since the back volume chamber of the speaker component is self-contained and therefore does not include portions of the device housing or other components of the portable electronic device).
The term “portable electronic device” as used herein may refer to any electronic device capable of being moved or transported by a user. For example, a portable electronic device may be a portable computer system (e.g., a laptop, portable general-purpose computer system, etc.), a mobile phone, a portable digital assistant (PDA), a digital music player, a digital video player, a portable gaming system, other portable devices, some combination thereof, etc.
As shown in
In one embodiment, a seal may be created between first portion 120 (e.g., around hole 126) and device housing 350. For example, sealant, adhesive, a gasket, or the like, may be disposed between first portion 120 and device housing 350. Since sound from receiver 110 propagated through device housing 350 may interfere with the operation of other components of portable electronic device 300 (e.g., a microphone disposed within device housing 350), embodiments may improve the operation of portable electronic device 300 by reducing the amount of sound from receiver 110 propagated through device housing 350.
By reorienting receiver 100 and redirecting the sound emitted from receiver 100 (e.g., using channel 360), embodiments provide design flexibility related to the mechanical design (e.g., how components and/or features of the portable electronic device are laid out or configured) and/or industrial design (e.g., how the components and/or features of the portable electronic device look). For example, by placing receiver 100 on its short or smaller dimension (e.g., dimension 111 as compared to larger dimension 112), embodiments reduce the footprint of receiver 110 and enable speaker hole 352 to be placed relatively close to other components (e.g., 380) of the portable electronic device (e.g., 300). Accordingly, embodiments enable speaker hole 352 to be located further from device housing edge 355, thereby making the portable electronic device more comfortable to use (e.g., by enabling a user's ear to rest against surface 357 of device housing 350 instead of edge 355) and improving the quality of the sound emitted from the portable electronic device (e.g., by improving the seal between a user's ear and device housing 350 around speaker hole 352).
Although
In one embodiment, speaker component 100 may utilize a sealed back volume chamber to improve the sound quality of receiver 110. For example, cavity 135 of second portion 130 may be joined with cavity 122 of first portion 120 (e.g., via hole 142 in interstitial layer 140), thereby forming a back volume chamber including cavity 135 and a portion of cavity 122 behind receiver 110. Additionally, receiver 110 may be sealed (e.g., by sealant, adhesive, a gasket, etc.) within cavity 122 of first portion 120 to reduce the ability for air to flow around receiver 110 (e.g., from channel 360 toward interstitial layer 140 and vice versa). Accordingly, the back volume chamber may be sealed or airtight with respect to ambient air (e.g., within channel 360, outside of speaker component 100, outside of device housing 350, etc.).
In one embodiment, hole 144 in interstitial layer may be used to join cavity 124 of first portion 120 to cavity 135 of second portion 130. Accordingly, the sealed back volume chamber may include cavity 124, cavity 135 and a portion of cavity 122 behind receiver 110.
Thus, embodiments provide design flexibility related to the size of back volume chamber of speaker component 100. For example, the size of the back volume chamber may be increased by increasing the number of cavities of the first portion 110 and/or second portion 130, by increasing the size of the cavities which form the back volume chamber, by adding holes in interstitial layer 140 to join additional cavities to the back volume chamber, some combination thereof, etc. Alternatively, the size of the back volume chamber may be decreased by reducing the number of cavities of the first portion 110 and/or second portion 130, by decreasing the size of the cavities which form the back volume chamber, by removing or blocking off holes in interstitial layer 140 to seal offer separate one or more cavities from the back volume chamber, some combination thereof, etc.
Further, embodiments provide design flexibility related to the shape of back volume chamber of speaker component 100. For example, in one embodiment, cavity 124 can be omitted from first portion 120 to make room for other components of the portable electronic device (e.g., 300). Alternatively, cavities may be added to speaker component 100 to fill unused space within the device housing (e.g., 350) of the portable electronic device (e.g., 300). In this manner, embodiments provide further design flexibility.
As shown in
In one embodiment, interstitial layer 140 may be a printed circuit board (PCB) with at least one layer. The electrical contacts (e.g., 146, 148 and 149) and/or any electrical interconnections between the electrical contacts (e.g., traces of the PCB) may be formed as part of the interstitial layer 140 (e.g., formed from at least one layer of the PCB) and/or mechanically coupled to the PCB (e.g., soldered onto the PCB, etc.).
Members 115 and 117 may be used to hold receiver 110 within cavity 122 of first portion 120 when speaker component 100 is in an assembled state (e.g., as shown in
In one embodiment, first portion 120 may be directly coupled to second portion 130, thereby omitting interstitial layer 140. Receiver 110 may be secured within cavity 122 by adhesive, sealant, or the like. The sealed back volume chamber may include cavity 135, cavity 124, a portion of cavity 122 behind receiver 110, or some combination thereof. The size and/or shape of the sealed back volume chamber may be changed by adding features to first portion 120 and/or second portion 130. For example, a portion of cavity 135 may be filled to seal off or separate cavity 124 from the back volume chamber. Further, electrical access to receiver 110 may be implemented by running wires from receiver 110 outside speaker component 100, where the area around the wires may be sealed to maintain or create the seal of the back volume chamber with respect to the ambient air.
In one embodiment, portion 470 may provide an increased surface area for sealing first portion 420 to device housing 450. For example, sealant, adhesive, a gasket, or the like, may be disposed between first portion 420 and device housing 450. Since sound from receiver 110 propagated through device housing 450 may interfere with the operation of other components of portable electronic device 300 (e.g., a microphone disposed within device housing 450), embodiments may improve the operation of portable electronic device 400 by further reducing the amount of sound from receiver 110 propagated through device housing 450.

Although portable electronic device 500 includes speaker component 100 as shown in
Speaker hole 352 may be substantially aligned or otherwise in proximity to hole 126, and therefore, speaker hole 352 may also be located relatively close to display device 510 as shown in
