Patent Application
20140079267
The field of the invention is speakers, in particular speakers intended for use in with portable devices.
The following background discussion includes information that could be useful in understanding the present inventive subject matter. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed inventive subject matter, or that any publication specifically or implicitly referenced is prior art.
Portable devices are growing rapidly in popularity, allowing users to enjoy music, video, texts, images, and other forms of entertainment without being tethered to a home system. Because of the sometimes inferior sound quality offered by speaker assemblies in such devices, an increasing number of people are connecting their portable devices to external speaker assemblies, including for example, docking stations.
One example of a speaker assembly that operates with a tablet computer is the ZookaTM Bluetooth Speaker shown at http://firewireblog.com/2012/02/16/zooka-bluetooth-speaker-for-the-ipad/. This device is an attachable Bluetooth speaker that couples with the top of a tablet computer. The Zooka comes with a rod that can be partially stored inside a cavity of the speaker, and screwed into a hole in the speaker housing. The rod, however, can easily be lost, and requires assembly for use as a stand. Moreover, the Zooka, while providing a somewhat improved audio experience, apparently fails to provide various speaker drivers (e.g., front-firing drivers, down-firing drivers, etc.) or a virtual surround system.
These and all other extrinsic materials discussed herein are incorporated by reference in their entirety. Where a definition or use of a term in an incorporated reference is inconsistent or contrary to the definition of that term provided herein, the definition of that term provided herein applies and the definition of that term in the reference does not apply.
Unless the context dictates the contrary, all ranges set forth herein should be interpreted as being inclusive of their endpoints, and open-ended ranges should be interpreted to include commercially practical values. Similarly, all lists of values should be considered as inclusive of intermediate values unless the context indicates the contrary.
Thus, there is still a need for a speaker assembly configured to provide an improved audio and video experience.
The inventive subject matter provides apparatus, systems and devices that provide a speaker assembly configured for use with a portable device, including for example, a tablet computer, a laptop, a mobile phone, or an electronic book reader.
In some aspects of the inventive subject matter, a speaker assembly comprises a leg and a receiver (e.g., slot, clamp, etc.) configured to receive an edge of a portable device. The leg and receiver are coupled to a housing having (1) a speaker, (2) sound perforations along a portion of the surface, and (3) a septum that separates a receiver biasing mechanism from an acoustic chamber. In some preferred embodiments, the mechanism chamber (i.e., the chamber housing the receiver biasing mechanism) has a smaller width than the acoustic chamber.
It is contemplated that the housing, leg, and receiver could be of any suitable size and shape. In some aspects of the inventive subject matter, a housing is sized and configured to accommodate some or all of a battery, a circuit board (e.g., a printed circuit board), a speaker, or a subwoofer, woofer, bass shaker, amplifier, tweeter, or any other suitable speaker driver.
It is contemplated that a receiver can be coupled to a receiver biasing mechanism (e.g., a button and spring biasing mechanism, a snap and release mechanism, or any other suitable mechanism) such that the receiver is in a first position or a second position depending on the position of the mechanism relative to the rest of the housing. For example, a clamp could loosen when a button is flush with the housing, and tighten when a button is extended away from the housing.
The portable device generally couples to the speaker assembly in such a way that the speaker acts as a sound emitter for the portable device (i.e., the sound that would normally be emitted from the portable device would instead be emitted from the speaker assembly). This coupling can be via one or more wired or wireless connections. All suitable connectors are contemplated, including for example, a multi-pin dock connector and an auxiliary cable.
Various objects, features, aspects and advantages of the inventive subject matter will become more apparent from the following detailed description of preferred embodiments, along with the accompanying drawing figures in which like numerals represent like components.
The inventive subject matter provides apparatus, systems and devices that provide a speaker assembly configured for use with a portable device.
One should appreciate that the disclosed techniques provide many advantageous technical effects including providing a single speaker system that allows a user to enjoy their portable devices in a wide variety of domestic and outdoor settings without the user having to manually hold onto the portable devices at what might be an uncomfortable angle. The sound system also allows users to enjoy media via a portable device with improved sound quality or volume.
The following discussion provides many example embodiments of the inventive subject matter. Although each embodiment represents a single combination of inventive elements, the inventive subject matter is considered to include all possible combinations of the disclosed elements. Thus if one embodiment comprises elements A, B, and C, and a second embodiment comprises elements B and D, then the inventive subject matter is also considered to include other remaining combinations of A, B, C, or D, even if not explicitly disclosed.
It is contemplated that the receiver (e.g., a clamp, etc.) could be pivotable, rotatable, or otherwise movable along the outside perimeter of the housing, to allow a user to modify an angle of the portable device's screen relative to the user without moving the speaker assembly.
Contemplated speaker housings can comprise any suitable size and shape, including for example, a cylinder, a cube, a rectangular cube, an egg, or a pyramid. Each component of the speaker assembly could be made of one or more materials, including for example, plastic, silicon, metal, wood, rubber, aluminum-coated polypropylene, aramid, cast aluminum, CMMD, a ceramic, foam, glass-imide, graphite-injected polypropylene, or any other suitable material.
In some embodiments of the inventive subject matter, the speaker assembly comprises a virtual surround system (e.g., ones that use head-related transfer function (HRTF) knowledge, reflections, diffuse sources, etc.) that creates the perception that there are additional sources of sound than are actually present.
Another component that could be included in a speaker assembly is a device (e.g., 206) that selectively mutes, edits or otherwise alters sounds, words or phrases that a user finds objectionable, e.g., profanities. One example of a device that selectively mutes some objectionable words in movies or television shows can be seen at http://www.tvguardian.com/.
It is contemplated that a hinge could be of any suitable size and type. Hinge 235, for example, comprises a spring mechanism that is configured in such a way that biases leg 240 in completely retracted and completely extended positions.
Receiver biasing mechanism chamber 335 extends across a first width 365 of the central width of housing 325, and acoustic chamber 360 extends across a second width 370 of the central width of housing 325. It is contemplated that a septum could divide a housing or a sub-housing (enclosed portion within a housing) into two chambers. In some preferred embodiments, and in
Various types of receiver biasing mechanisms are contemplated, including for example, a spring coupled with a button, slider, or other actuator, or any other mechanism or device configured to bias a first portion of a receiver to a first position relative to a second portion of the receiver.
Septum 450 comprises first and second endpoints or protrusions, 451 and 452, configured to fit into recesses 453 and 454 or housing 425. It is contemplated that septum 450 remains in a first position, such that acoustic chamber 460 is unaffected by actuation of the receiver biasing mechanism 475.
In some preferred embodiments, the mechanism chamber 455 extends along a first outer edge of the interior of a housing, while acoustic chamber 460 extends along a second outer edge of the interior of a housing. First outer edge could be shorter, equal to, or longer than the second outer edge.
Acoustic chamber 460 could comprise one or more components of speaker assembly 400, including for example, a battery 480, a circuit board 485 (e.g., a printed circuit board), or any other housing component. Some of the acoustic chamber's volume should be free of mechanical and electrical components such that the natural acoustic qualities of the assembly are retained. In some preferred embodiments, at least 20%, 40%, 50%, or even 75% or more of the acoustic chamber's volume is free of mechanical and electrical components. It is also contemplated that the acoustic chamber could be substantially or completely enclosed.
In preferred embodiments, it is contemplated that a user can selectively manipulate different frequencies emitting from the speaker assembly. For example, equalization (EQ) and head-related transfer function (HRTF) can be accomplished by digital signal processing or analog means, either jointly or independently.
Contemplated speaker assemblies could comprise additional components that allow a user to interact with the assembly. As an example, a physical button, a touch-screen button or a slider on a display (e.g., LED screen or other screen coupled with the housing), or other control could allow a user to adjust a volume or a setting of the speaker assembly. Thus, a user could press a button to increase a volume of one side of the speaker and press another button to decrease a volume of another side of the speaker. The user could also adjust a sound immersion parameter or intensity. Moreover, it is contemplated that a user could control a function of the portable device via the speaker assembly (e.g., pause, play, stop, etc.).
As used in the description herein and throughout the claims that follow, the meaning of “a,” “an,” and “the” includes plural reference unless the context clearly dictates otherwise. Also, as used in the description herein, the meaning of “in” includes “in” and “on” unless the context clearly dictates otherwise.
Groupings of alternative elements or embodiments of the inventive subject matter disclosed herein are not to be construed as limitations. Each group member can be referred to and claimed individually or in any combination with other members of the group or other elements found herein. One or more members of a group can be included in, or deleted from, a group for reasons of convenience and/or patentability. When any such inclusion or deletion occurs, the specification is herein deemed to contain the group as modified thus fulfilling the written description of all Markush groups used in the appended claims.
As used herein, and unless the context dictates otherwise, the term “coupled to” is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms “coupled to” and “coupled with” are used synonymously.
It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the scope of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps could be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C . . . and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
