This disclosure generally relates to sound systems integrated within furniture.
Speaker systems are widely used for home, business, social accommodations, entertainment and for practical, commercial, and household uses. Unfortunately, speaker systems take up a great deal of space in a home, office, or business environment, and even if small, they are often unsightly. Moreover, wiring and cabling associated with such systems is also unsightly and cumbersome.
Furniture also tends to take up a great deal of space in a home, office or business environment. When sitting on furniture, it is often desirable to listen to music, watch TV, or watch a movie in a home theater environment, or employ one or more electronic components. Improved furniture is needed with improved electronic assembly systems that can be used in association with modern furniture assemblies or devices.
The subject matter claimed herein is not limited to embodiments that solve any disadvantages or that operate only in environments such as those described above. Rather, this background is only provided to illustrate one exemplary technology area where some embodiments described herein may be practiced.
Embodiments of the present disclosure solve one or more of the foregoing or other problems in the art with systems, methods, and apparatuses for acoustically correcting sound loss through various types and compositions of fabric. In particular, systems, methods and apparatuses of the present disclosure can be implemented to improve the sound quality of a speaker system having at least one speaker integrated with a furniture component and covered with an upholstery fabric. Such upholstery fabrics are typically not at all acoustically transparent, but are rather configured to provide a combination of durability and aesthetics to a seating or other furniture surface.
In particular, one or more embodiments can include an audio-enhanced furniture system including a furniture assembly; an upholstery fabric at least partially covering the furniture assembly; and a speaker system positioned within the furniture assembly, the speaker system including a speaker covered by the upholstery fabric. The speaker is configured to be tuned to compensate for sound being emitted from the speaker through the upholstery fabric by adjusting the equalization of one or more target frequencies or frequency bands emitted by the speaker. Embodiments can also include a plurality of tuning profiles corresponding to a plurality of upholstery fabrics, wherein a user may select a tuning profile from the plurality of tuning profiles.
Embodiments of a method of tuning a speaker to compensate for sound being emitted through upholstery fabric can include: selecting a desired baseline equalization (e.g., desired frequency response), configuring the speaker to emit sound at an actual equalization (e.g., frequency response) approximate to the desired baseline equalization or frequency response; covering the speaker with an upholstery fabric; measuring a resultant equalization or frequency response as the speaker emits sound through the upholstery fabric; calculating a differential equalization; and reconfiguring the audio system to emit sound through the upholstery fabric according to the desired baseline equalization or frequency response by adjusting the actual equalization or frequency response by the differential equalization. Methods can also include creating a plurality of tuning profiles corresponding to a plurality of upholstery fabrics, each tuning profile including a differential equalization calculated for each of the plurality of upholstery fabrics.
Systems of the present disclosure also include audio-enhanced modular furniture systems having: a modular furniture assembly including one or more bases, a plurality of upright members, at least two of the upright members being audio-enhanced upright members, and a speaker system positioned within the modular furniture assembly. The speaker system can include (a) at least one speaker mounted within a first audio-enhanced upright member, the at least one speaker being hidden from view by a first upholstery fabric that covers the first audio-enhanced upright member; (b) at least one speaker mounted within a second audio-enhanced upright member, the at least one speaker being hidden from view by a second upholstery fabric that covers the second audio-enhanced upright member; and (c) at least one speaker controller configured to control each speaker of the speaker system. Each speaker of the speaker system can be configured to be tuned through the at least one speaker controller to compensate for sound being emitted from the speaker through the respective first or second upholstery fabric by adjusting the equalization of one or more audio frequencies emitted by the at least one speaker.
Methods of the present disclosure can also include methods for tuning speakers in modular furniture including (a) providing an assemble-able modular furniture assembly having one or more bases, a plurality of upright members, wherein at least one of the upright members is an audio-enhanced upright member, and a speaker system including at least one speaker mounted within the first audio-enhanced upright member, the at least one speaker being hidden from view by a first upholstery fabric that covers the first audio-enhanced upright member; and (b) tuning the at least one speaker mounted within the first audio-enhanced upright member to compensate for sound being emitted from the at least one speaker through the first upholstery fabric by adjusting the decibel level of one or more audio frequencies emitted by the at least one speaker.
Accordingly, systems and methods for acoustically correcting sound loss through fabric are disclosed.
This Brief Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
Additional features and advantages will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by the practice of the teachings herein. Features and advantages of the invention may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. Features of the present invention will become more fully apparent from the following description and appended claims, or may be learned by the practice of the invention as set forth hereinafter.
In order to describe the manner in which the above-recited and other advantages and features can be obtained, a more particular description of the subject matter briefly described above will be rendered by reference to specific embodiments which are illustrated in the appended drawings. Understanding that these drawings depict only typical embodiments and are not therefore to be considered to be limiting in scope, embodiments will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
One or more specific embodiments of the present disclosure will be described below. In an effort to provide a concise description of these embodiments, some features of an actual embodiment may be described in the specification. It should be appreciated that in the development of any such actual embodiment, as in any engineering or design project, numerous embodiment-specific decisions will be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which may vary from one embodiment to another. It should further be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.
One or more embodiments of the present disclosure may generally relate to apparatuses, methods, and systems for acoustically correcting sound loss through various types and compositions of fabric. The apparatuses, methods, and systems provide superior sound quality to speaker systems that include at least one speaker covered with fabric. The apparatuses, methods, and systems are used to improve the balance of audible frequencies emitted by a speaker through a fabric covering. The apparatuses, methods, and systems can use various mechanical, electromechanical, electrical, hardware and/or software components, systems, and modules to improve audio or speaker systems integrated within furniture, whether it be a modular furniture assembly or a single integral furniture unit having integrated speakers.
While the present disclosure will describe particular implementations of apparatuses, methods, and systems, it should be understood that the apparatuses, methods, and systems described herein may be applicable to other uses. Additionally, elements described in relation to any embodiments depicted and/or described herein may be combinable with elements described in relation to any other embodiment depicted and/or described herein.
For instance, “tuning” of a speaker or system of speakers, as discussed throughout the present disclosure, is to be understood to encompass all methods currently known for adjusting the frequency response of the subject speaker or system of speakers. Such methods include but are not limited to adjustment of the equalization of frequencies of a sound signal prior to transmission to the speaker or speaker system, adjustment of a transmitted audio signal prior to its receipt by the speaker or speaker system, or direct modification of the speaker(s).
The disclosed embodiments bring about substantial benefits, improvements, and practical implementations to the technical field. By way of example and not limitation, the improved tuning of audio or speaker systems having speakers covered with fabric provides superior sound quality in applications where it is desired to have a speaker concealed from view. This leads to substantial opportunities for improved aesthetic and functional designs of speaker systems integrated with furniture, thereby leading to substantial improvements in the technical field. These and numerous other benefits will now be discussed in more detail with regard to the Figures presented by this disclosure.
The following section outlines some example improvements and practical applications provided by the disclosed embodiments. It will be appreciated, however, that these are just examples only and that the embodiments are not limited to only these improvements. Generally, now referring to the drawings in detail wherein like reference numerals are used to designate like elements, there is shown one or more embodiments of the present disclosure that provides apparatuses, methods, and systems.
Embodiments of the present disclosure are applicable to a variety of applications wherein audio speakers are covered with fabric not only to improve the aesthetic design of an audio system, but to provide desired aesthetics and durability in a furniture system (e.g., a chair, sofa or other furniture providing seating, or a bed). One such application can be found in audio-enhanced furniture systems including a furniture assembly, an upholstery fabric at least partially covering the furniture assembly, and an audio or speaker system positioned within the furniture assembly, wherein at least one of the speakers is covered and hidden from view by the upholstery fabric that at least partially covers the furniture assembly. According to embodiments of the present disclosure, each speaker that is covered by an upholstery fabric can be tuned to compensate for sound being emitted from the speaker through the upholstery fabric by an adjustment to an equalization or frequency response of the speaker at one or more target frequencies or frequency bands. In particular, adjustment of the equalization or frequency response of the speaker may depend on at least one of a fabric type, a density, a thickness, and a weight of the upholstery fabric covering the furniture assembly. In some embodiments, the tuning of each speaker, or tuning of the audio system or speaker system to change the frequency response of each speaker, is selectable from a plurality of tuning profiles corresponding to a variety of upholstery fabrics, such that a user, retailer, or manufacturer is able to select a tuning profile configured to specifically compensate for sound loss through a particular upholstery fabric.
The density and thickness of the upholstery fabric relate to the weight of the upholstery fabric. For instance, a higher density and thicker upholstery fabric can have a higher weight than a lower density and less thick upholstery fabric. Examples of weights of upholstery fabrics that can be used as covers for the furniture assemblies (and modular components/members thereof) of the present invention include, for example: fabrics having weights in a range of approximately 50 grams per square meter (GSM) to approximately 1500 grams per square meter (GSM), for example, such as approximately 100 GSM to approximately 1000 GSM, or such as approximately 190 GSM to approximately 800 GSM, although a variety of different interior and exterior fabrics may be employed. The speakers of the present invention are adjusted and tuned in order to emit sound through such fabrics in a manner that attenuation due to such fabric is compensated for.
Embodiments of a tuning profile include the information used to adjust the equalization of frequency response of a speaker to compensate for sound loss through a particular upholstery fabric. For example, a range of audible frequencies emitted by a speaker can be divided into a plurality of frequency bands, with each of those frequency bands having a frequency response adjustment to compensate for sound loss through a particular upholstery fabric. The particular grouping of those frequency response adjustments, with a particular identification for the particular upholstery fabric can be an example of a tuning profile.
The total quantity of frequency bands depends on the desired level of accuracy in adjustment of the frequency response, as well as the capability of the intended equipment for implementing the tuning profile. For example, some audio tuning devices, such as speaker controllers, amplifiers, or audio equalizers, are only capable of adjusting frequencies in the three frequency bands corresponding to low frequency ranges (i.e., bass), middle frequency ranges, and high frequency ranges (i.e., treble), whereas other tuning devices available are operable to adjust up to 31 separate frequency ranges.
Some of the embodiments discussed herein, for example, divide the audible frequencies ranging from about 20 Hz to about 21 kHz into the 10 frequency bands for individual adjustment as illustrated in Table 1 below: about 20 Hz to about 49 Hz, about 50 Hz to about 99 Hz, about 100 Hz to about 199 Hz, about 200 Hz to about 399 Hz, about 400 Hz to about 999 Hz, about 1 kHz to about 1.9 kHz, about 2 kHz to about 3.9 kHz, about 4 kHz to about 7.9 kHz, about 8 kHz to about 15.9 kHz, and about 16 kHz to about 21 kHz.
Alternatively, a plurality of target frequencies within the audible frequency range can be selected for adjustment by parametric equalization or similar known methods. Parametric equalization includes adjustment of one or more target frequencies by a selected amplitude, such the frequency response curve of the tuned speaker is altered by a parametric or “bell” shape centered at the target frequency. The particular data associated with the parametric equalization for one particular upholstery fabric, with a particular identification for the particular upholstery fabric can be another example of a tuning profile. One skilled in the art should appreciate that additional methods of adjusting equalization or frequency response not discussed herein can be used to implement the disclosed embodiments within the scope and spirit of the disclosed invention.
The terms “equalization” and “frequency response” are used interchangeably herein to describe adjustments to the output volumes of one or more frequencies within the audible spectrum of sound emitted by a speaker or speaker system.
Referring now to the drawings,
According to embodiments of the present disclosure, the system of speakers 102 covered by upholstery fabric 104a, 104b, are tuned to compensate for sound being emitted from each speaker 102 through upholstery fabric 104a, 104b by an adjustment to an equalization (i.e., adjustment of the frequency response) of the at least one speaker at one or more target frequencies or frequency bands. Adjustment of the equalization of one or more target frequencies or frequency bands depends on at least one of a fabric type, a density, a thickness, and a weight of upholstery fabric 104a, 104b.
Further, the tuning of speakers 102 can be implemented by one or more speaker controllers in communication with and configured to control the tuning of each speaker 102. For example, modular furniture assembly 100 includes a receiver/amplifier 110, such being an example of a speaker controller, configured to receive signals from an audio source, such as mobile device 112 (via wired connection or wireless signal) and operable to transmit the received signals and provide power to speakers 102. Tuning of speakers 102 can thus be implemented by receiver/amplifier 110 via firmware or other known methods for adjusting the equalization of the output of an amplifier. Alternatively, tuning can be implemented by adjusting the equalization of the audio signals transmitted by the audio source (e.g., by execution of tuning software on mobile device 112). Additionally, the tuning of speakers 102 can be made selectable by mobile device 112, or by any means for communicating with the receiver/amplifier 110, such as a remote controller, a control console, mobile device, such as a cellular phone, or combinations, modifications, or alternatives thereof. Alternatively, the tuning can be permanently implemented via firmware associated with receiver/amplifier 110. In some embodiments, a microphone 135 is also provided to enable custom tuning of speakers 102 according to the methods disclosed herein. Alternatively, the disclosed methods can be performed by the consumer using a microphone of mobile device 112.
While modular furniture assembly 100 is depicted with receiver/amplifier 110 mounted within base 106, embodiments also include receivers, amplifiers, and/or speaker controllers provided at virtually any location that allows for communication with speakers 102. For example, receiver/amplifier 110 can be integral with a center console or similar device, and can be connected to speakers 102 via wired or wireless connections. Alternatively, each speaker 102 can have a speaker controller individually associated therewith and secured directly or proximate thereto. One skilled in the art should appreciate that the illustrated embodiments are provided as exemplary configurations and do not limit the scope or spirit of the present disclosure to the physical configuration specifically illustrated.
While mobile device 112 is illustrated as an exemplary audio source, it will be appreciated that any of a wide variety of sources may be used with the present systems (e.g., including, but not limited to TV, disc player such as a CD player, DVD player, Blu-ray player, over-the air radio, TV or other transmissions, etc.). Additionally, the mobile device 112 can be used not only as an audio source, but can optionally control other audio sources, such as those described herein, and so allow a user to tune the speakers 102 based upon the signals received by other audio sources. For instance, and not by way of limitation, the mobile device 112 can tune the speakers 102 based upon a TV, disc player such as a CD player, DVD player, Blu-ray player, over-the air radio, TV or other transmissions, etc. providing a signal to the receiver/amplifier 110. The mobile device 112 can, therefore, be another speaker controller.
As shown in
As shown in
By way of an additional example,
As yet another example,
Although
Because the speakers are positioned within the modular furniture assembly components, this provides great flexibility to a user in where the speakers can be positioned within the assembled furniture assembly, whether the assembly is modifiable by the user, custom built according to the user's request, or otherwise provided. Further, the use of interchangeable covers for each of the modular furniture assembly components enables the user to change upholstery fabrics at will. Accordingly, embodiments of the present disclosure also enable a user to selectively tune the speakers of an audio-enhanced furniture assembly to compensate for sound loss through the fabric selected by the user, as discussed further herein.
Referring now to
In the example illustrated by
Alternatively, the exemplary audio system 129 of
As illustrated in
Embodiments also include methods and systems for enabling speaker system 130 to be configured by a user to account for sound loss through any fabric covering speakers 132a, 132b, etc. of speaker system 130 without a predetermined tuning profile (i.e., methods allowing a user to create a new tuning profile corresponding to the actual fabric covering speakers 132a, 132b, etc.). For instance,
Such auto-tuning embodiments further includes using the user input device 144 as a computer system that is operable to apply the methods disclosed herein. The user input device 144 is in communication with network 149 and includes a necessary hardware and software for implementing the disclosed methods. Alternatively, a separate personal computer, a mobile device, and so forth could communicate with the microphone 135, either directly or via the network 149. As such, the user input device 144, for instance, is in communication with microphone 135 to receive audio measurements therefrom as speaker system 130 emits a preset sequence of audio tones stored within storage 142, or within a remote computer system communicating with the speaker system 130, or otherwise transmitted to speaker system 130 via audio source 134. Microphone 135 is operable to measure the tones emitted by speaker system 130 through the fabric. Having received the measurements from microphone 135, the user input device 144 is able to calculate adjustments to the equalization of speaker system 130 according to the methods disclosed herein to create a new tuning profile 140 and communicate with tuning module 138 to store the new tuning profile 140 within storage 142 and to implement the tuning profile to adjust the equalization of each speaker 132a, 132b, etc. of speaker system 130. It will be understood that a separate computer system 145 could apply the methods disclosed herein, including the auto-tuning using the microphone 135.
The schematic illustration of portions of the audio systems described here can be considered as representations of functional modules or components to perform particular operations. Generally, the operation modules, controllers, systems, etc. described herein may refer to software objects or routines that execute on a special purpose processing device to perform a certain function or group of functions. In at least some instances, a hardware processor is provided that is operable to carry out executable instructions for performing a method or process, such as the methods and processes disclosed herein. It is contemplated that implementations in hardware or a combination of software and hardware are possible. For instance, the controllers, modules, systems, etc. described herein may include the use of computer hardware or software modules. Such hardware and software modules or structures may include a processor and computer storage media carrying instructions that, when executed by the processor and/or caused to be executed by the processor, perform any one or more of the methods disclosed herein, or any part(s) of any method disclosed. By way of example, and not limitation, such computer storage media may comprise hardware storage such as solid state disk/device (SSD), RAM, ROM, EEPROM, CD-ROM, flash memory, phase-change memory (“PCM”), or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other hardware storage devices which may be used to store program code in the form of computer-executable instructions or data structures, which may be accessed and executed by a general-purpose or special-purpose computer system to implement the disclosed functionality of the invention. Combinations of the above should also be included within the scope of computer storage media. Such media are also examples of non-transitory storage media, and non-transitory storage media also embraces cloud-based storage systems and structures, although the scope of the invention is not limited to these examples of non-transitory storage media.
The functionality and operation of the controller/amplifier, user input device, audio source, speaker system, audio system, and other structures and components described herein can be performed, at least in part, by one or more hardware logic components. For example, and without limitation, illustrative types of hardware logic components/processors that can be used include Field-Programmable Gate Arrays (“FPGA”), Program-Specific or Application-Specific Integrated Circuits (“ASIC”), Program-Specific Standard Products (“ASSP”), System-On-A-Chip Systems (“SOC”), Complex Programmable Logic Devices (“CPLD”), Central Processing Units (“CPU”), Graphical Processing Units (“GPU”), or any other type of programmable hardware.
Optionally, while the user input device 144 and audio source 134 are illustrated as communicating directly with the controller/amplifier 136 and/or the speaker system 130 as illustrated in
Method 146 begins with act 146a of selecting a baseline equalization of one or more audio frequencies for a speaker of an audio system, such as the audio systems illustrated in
As a non-limiting example, baseline decibel levels for each target frequency or frequency band of a baseline equalization can be between about 40 decibels or less, 60 decibels or less, 70 decibels or less, 90 decibels or less, 100 decibels or less, 120 decibels or less, or 130 decibels or less. Stated another way, the baseline equalization can be based upon baseline decibel levels from about 40 decibels to about 130 decibels, from about 60 decibels to about 120 decibels, or from about 70 decibels to about 100 decibels. Further, the baseline decibel levels of each target frequency or frequency band can be adjusted if it is found that the previously selected decibel level is too low to be heard or detected by a microphone, such as microphone 135, as the sound passes through the selected fabric. Further still, methods as disclosed herein may be performed at a variety of baseline decibel levels to determine accurate adjustments to the baseline equalization at each selected decibel level.
In act 146b, the audio system is configured to emit each of the one or more target frequencies or frequency bands from the speaker at an actual volume according to the selected baseline equalization. For example, for a frequency range of about 20 Hz to about 21 kHz, the frequency range can include up to 3, up to 5, up to 10, up to 31 target frequencies, or up to one target frequency for each frequency of the range so that for a range from 0 Hz to about 21 kHz there can be 21,000 target frequencies. Stated another way, the full frequency range could be adjusted at each frequency as would be characterized by a continuous equation, or through a step function as would result in bands. A particular frequency range can be divided into a number of frequency bands, such as about 1 to about 21000 target frequency bands, about 1 to about 31 target frequency bands, about 2 to about 20 target frequency bands, about 3 to about 15 target frequency bands, or from about 5 to about 10 target frequency bands. More specifically, as an example only, the following 10 target frequencies can be selected for adjustment: about 32 Hz, about 63 Hz, about 125 Hz, about 250 Hz, about 500 Hz, about 1 kHz, about 2 kHz, about 4 kHz, about 8 kHz, and about 16 kHz. The target frequencies can also be implemented as frequency bands, such as, for example, the following 10 frequency bands, as provided in Table 1: about 20 Hz to about 49 Hz, about 50 Hz to about 99 Hz, about 100 Hz to about 199 Hz, about 200 Hz to about 399 Hz, about 400 Hz to about 999 Hz, about 1 kHz to about 1.9 kHz, about 2 kHz to about 3.9 kHz, about 4 kHz to about 7.9 kHz, about 8 kHz to about 15.9 kHz, and about 16 kHz to about 21 kHz. One skilled in the art should appreciated that adjustment of target frequencies or frequency bands can be implemented by a variety of devices currently available, such as a parametric equalizer, a graphical equalizer, a semi-graphical equalizer, a custom designed equalizer, and so forth.
After the audio system has been configured according to the selected baseline configuration, act 146c includes covering the speaker with a selected upholstery fabric. Preferably, the selected upholstery fabric is either the same upholstery fabric as or substantially similar in fabric type, density, thickness, and a weight to an upholstery fabric intended to be used to cover a speaker system product, such as an audio-enhanced furniture assembly, during use.
With the speaker covered by the selected upholstery fabric, act 146d includes activating the audio system and measuring a resultant volume of each of the one or more target frequencies as the speaker emits sound through the selected upholstery fabric. The resultant volume of the one or more target frequencies will differ based on the fabrics used to cover the speaker, with the resulting frequency response affected differently, depending at least one of, for example, fabric type, density, thickness, or weight. For example, one fabric may significantly affect certain frequencies while having only a nominal or substantially no effect on others, and an alternative fabric may affect different frequencies by varying amounts, as discussed further herein.
At act 146e, a differential volume is calculated between the actual volume of each of the one or more target frequencies from act 146b and the resultant volume of each of the one or more target frequencies measured in act 146d. These differential volumes can be calculated for any number of audio frequencies, preferably at least for each audio frequency or frequency band that is adjustable by the audio system. When the audio system emits target frequencies, in one example configuration, ranging from about 20 Hz to about 21 kHz, with a baseline ranging from about 70 dB to about 100 dB over the range of about 20 Hz to about 21 kHz, the compensation values can be up to about 25 dB for each of the one or more adjusted frequency bands, with the adjusted frequency bands having a band width of about 1 Hz to about 4000 Hz, from about 2 Hz to about 2000 Hz, from about 3 Hz to about 1000 Hz, from about 4 Hz to about 500 Hz, from about 5 Hz to about 200 Hz, from about 5 Hz to about 100 Hz, from about 5 Hz to about 50 Hz, combinations and/or modification thereof, or some other band width for the selected target frequency or target frequency band. Stated another way, the compensation values can range from about 1 dB to about 25 dB when compensation of a particular frequency band occurs for a particular fabric during tuning. Alternatively, the compensation values can range from about 1 dB to about 30 dB, from about 2 dB to about 21 dB, from about 3 dB to about 16 dB, from about 1 dB to about 21 dB, or from about 1 dB to about 16 dB.
In other examples, the differential volumes can be, as provided in Table 2, up to about 2 dB, about 4 dB, or about 5 dB for a target frequency of about 32 Hz or a frequency band of about 20 Hz to about 49 Hz; up to about 1 dB, about 4 dB, or about 5 dB for a target frequency of about 63 Hz or a frequency band of about 50 Hz to about 99 Hz; up to about 3 dB, about 4 dB, or about 5 dB for a target frequency of about 125 Hz or a frequency band of about 100 Hz to about 199 Hz; up to about 1 dB, about 4 dB, or about 5 dB for a target frequency of about 250 Hz or a frequency band of about 199 Hz to about 399 Hz; up to about 1 dB, about 4 dB, or about 5 dB for a target frequency of about 500 Hz or a frequency band of about 400 Hz to about 999 Hz; up to about 3 dB, about 5 dB, or about 7 dB for a target frequency of about 1 kHz or a frequency band of about 1 kHz to about 1.9 kHz; up to about 8 dB, about 10 dB, or about 12 dB for a target frequency of about 2 kHz or a frequency band of about 2 kHz to about 3.9 kHz; up to about 11 dB, about 14 dB, or about 16 dB for a target frequency of about 4 kHz or a frequency band of about 4 kHz to about 7.9 kHz; up to about 15 dB, about 18 dB, or about 20 dB for a target frequency of about 8 kHz or a frequency band of about 8 kHz to about 15.9 kHz; and up to about 16 dB, about 21 dB, or about 25 dB for a target frequency of about 16 kHz or a frequency band of about 16 kHz to about 21 kHz. It is to be understood that the foregoing volume adjustments include lower magnitude adjustments below the presented upper limit, such as, for example, increasing the volume of each target frequency or frequency band expressed above by a magnitude from about 1 decibel to the presented maximum number of decibels.
The foregoing adjustments are provided as examples and are not intended to limit the scope of the present disclosure. For instance, while certain differential volumes are provided in each of Examples 1-3, it will be understood that any differential volumes from any examples can be combined together. For instance, any differential volumes of Example 1 can be combined with any differential volumes of either or both of Example 2 and 3. Additionally, any differential volumes of Example 2 can be combined with any differential volumes of either or both of Example 1 and 3. Additionally, any differential volumes of Example 3 can be combined with any differential volumes of either or both of Example 1 and 2.
Finally, in act 146f, the audio system is reconfigured to compensate for sound loss through the selected upholstery fabric by adjusting the actual volume of each of the one or more target frequencies or frequency bands emitted by the speaker and adjustable by the audio system by the corresponding calculated differential volume. As illustrated in Table 2, some embodiments include adjustments to higher frequencies (e.g., frequencies around 1 kHz or higher) that are greater in magnitude than adjustments made to lower frequencies. The exact magnitude of adjustment to each target frequency or frequency range depends on the magnitude of volume that is attenuated (i.e., reduced) by the particular fabric covering the speaker.
Method 146 may also include creation of a tuning profile corresponding to the selected upholstery fabric, such that the tuning profile may be implemented to tune any speaker covered by a fabric identical or similar to the selected upholstery fabric to compensate for sound loss through the upholstery fabric. The tuning profile created may include a fabric identifier and the calculated differential volume of each of the one or more target frequencies or frequency bands as obtained by methods of the present disclosure. Alternatively, the tuning profile may include a fabric identifier and ratios of the differential volume and the baseline volume to allow for linear adjustment of equalization as the overall volume level of the speaker is altered by a user. Also, differential volumes and/or ratios may be calculated at varying levels of overall volume by repeating method 146 for each of the various levels of overall volume, thus creating a stepwise volume adjustment profile. The calculated differential volumes or volume ratios of a tuning profile can thus be used to tune a speaker or speaker system by adjusting the actual volume of the one or more frequencies for which a calculated differential volume is provided.
Additional tuning profiles can also be created using methods of the present disclosure, each tuning profile corresponding to an additional upholstery fabric. For instance, during act 146c of method 146, the selected upholstery fabric may be replaced with each additional upholstery fabric in turn, then the remaining acts carried out for each additional upholstery fabric to create a corresponding tuning profile.
Accordingly, a speaker mounted within a furniture assembly can be tuned according to any of the tuning profiles, such as tuning profiles 140, 140a, 140b (
The assemble-able modular furniture assembly, for example, can include one or more bases, a plurality of upright members configured to attach to the one or more bases, and a speaker system, wherein at least one of upright members is an audio-enhanced upright member, such as the modular furniture assemblies illustrated in
According to act 148b, a plurality of predetermined tuning profiles is presented, each corresponding to an upholstery fabric and each operable by the speaker controller to adjust a volume of one or more target frequencies or frequency bands emitted by the at least one fabric-covered speaker to compensate for sound being emitted from the at least one speaker through the upholstery fabric.
In response to selection of a tuning profile, act 148c includes tuning the at least one fabric-covered speaker via the speaker controller to adjust an actual volume of one or more target frequencies or frequency bands by a magnitude approximately equal to a calculated differential volume included in the selected tuning profile. The calculated differential volume of each of the one or more audio frequencies is equal to the difference between: (i) a baseline volume corresponding to sound emitted from the at least one speaker or a similar speaker, and (ii) a resultant volume corresponding to sound emitted from the at least one speaker or similar speaker when covered with the first upholstery fabric or a similar fabric. Tuning of the at least one speaker can be accomplished by any known means of adjusting the equalization of audio frequencies of a speaker or speaker system, such as but not limited to the means discussed in connection with
One skilled in the art should appreciate that the disclosed methods can be performed under various circumstances. For instance, tuning profiles can be predetermined for one or more selected fabrics during design or development of an audio system, such as an audio-enhanced furniture assembly. Also, the plurality of tuning profiles can be presented and selectable via a user interface on a mobile device, a remote-control device, or a dedicated console associated with the speaker system. Alternatively, the furniture assembly can be provided to the consumer with a tuning profile already selected based on the upholstery fabric selected by the user when ordering the furniture. In at least one embodiment, the disclosed methods can be applied to an existing speaker, audio system, or speaker system having speakers at least partially covered in fabric to improve the sound quality of the existing system. As discussed herein, a user may be provided with means, such as a microphone or software capable of operating a microphone of a mobile device, for measuring the actual volume emitted through the fabric covering one or more speakers to determine a resultant volume of one or more target frequencies, calculate a differential volume for each target frequency, and reconfigure the existing system to adjust the actual volume of each target frequency, or corresponding frequency band, as emitted by each speaker to compensate for sound loss through the fabric.
Additionally, some embodiments include an assemble-able modular furniture assembly with a plurality of speakers, each speaker being separately tunable by separate selection of one of the pluralities of tuning profiles. In some embodiments, a user can select a tuning profile from the plurality of tuning profiles via a dedicated console, a remote controller, or a user interface of a mobile device or computer system, for the speaker system as a whole or for each individual speaker, depending on the placement of fabrics relative to the speakers included with the assemble-able modular furniture assembly.

These frequencies F1-Fn can include, for example, 32 Hz, 63 Hz, 125 Hz, 250 Hz, 500 Hz, 1 kHz, 2 kHz, 4 kHz, 6 kHz, and 16 kHz. These frequencies F1-Fn can include, for example, any frequencies ranging from about 20 Hz to about 21 kHz, with one or more adjustable frequencies from 20 Hz to 49 Hz, with one or more adjustable frequencies from 50 Hz to 99 Hz, with one or more adjustable frequencies from 100 Hz to 199 Hz, with one or more frequencies from 200 Hz to 399 Hz, with one or more frequencies from 400 Hz to 399 Hz, with one or more frequencies from 1 kHz to 1.999 kHz, with one or more frequencies from 2 kHz to 3.999 kHz, with one or more frequencies from 4 kHz to 7.999 kHz, with one or more frequencies from 8 kHz to 15.999 kHz, and with one or more frequencies from 16 kHz to 21 kHz. Alternatively, one or more of the foregoing frequency ranges can be targeted for adjustment using, for example, a graphical equalizer or similar device. Also, one skilled in the art should appreciate that the total range of frequencies selected for adjustment is not limited to between 20 Hz and 21 kHz but can be expanded to include any lower or higher frequencies if so desired.
A baseline equalization of the selected audio frequencies F1-Fn can then be selected, the baseline equalization including actual desired volumes V1-Vn corresponding to the selected audio frequencies F1-Fn (e.g., a desired frequency response curve for the speaker). Embodiments may include virtually any baseline equalization that enables measurement of the volume of each target frequency or frequency band as the speaker emits sound through the fabric for which the speaker is to be tuned. In other words, the volume of each target frequency within the selected baseline equalization needs to be sufficiently high to enable the proceeding method steps to be performed accurately.
Once the baseline equalization frequencies F1-Fn and the actual desired volumes V1-Vn are determined, resultant volumes V1_fabric1-Vn_fabric1 corresponding to sound emitted from a speaker through a first fabric (fabric1) can be determined according to methods of the present disclosure, and corresponding differential volumes ÄV1-ÄVn can be calculated and stored as a tuning profile corresponding to the first fabric, such that the calculated differential volumes ÄV1-ÄVn may be used to adjust the equalization of a speaker (the speaker's frequency response) covered by the first fabric, or a fabric similar thereto, to compensate for sound loss through the fabric. The disclosed methods can be performed for any number of fabrics to create corresponding tuning profiles in this manner. The differential volumes ÄV1-ÄVn vary based upon the particular audio frequencies F1-Fn being tested. As an alternative to adjusting discrete target frequencies F1-Fn (e.g., by parametric equalization at each target frequency F1-Fn), the differential volumes ÄV1-ÄVn can be applied to frequency bands that respectively include target frequencies F1-Fn (e.g., by graphical equalization at each respective frequency band).
Adjustments to the equalization or frequency response of a speaker can alternatively be implemented as a ratio of the calculated differential volume and the respective baseline volume, such that the equalization adjustment depends on the volume level of the speaker as selected by a user.
For example, and as illustrated in Table 3, each audio frequency can be adjusted by a multiplication factor or ratio up to about 1.03, about 1.06, or about 1.07 for a target frequency of about 32 Hz or a frequency band of about 20 Hz to about 49 Hz; up to about 1.01, about 1.05, or about 1.06 for a target frequency of about 63 Hz or a frequency band of about 50 Hz to about 99 Hz; up to about 1.03, about 1.04, or about 1.05 for a target frequency of about 125 Hz or a frequency band of about 100 Hz to about 199 Hz; up to about 1.01, about 1.04, or about 1.05 for a target frequency of about 250 Hz or a frequency band of about 199 Hz to about 399 Hz; up to about 1.01, about 1.04, or about 1.06 for a target frequency of about 500 Hz or a frequency band of about 400 Hz to about 999 Hz; up to about 1.03, about 1.06, or about 1.08 for a target frequency of about 1 kHz or a frequency band of about 1 kHz to about 1.9 kHz; up to about 1.09, about 1.11, or about 1.13 for a target frequency of about 2 kHz or a frequency band of about 2 kHz to about 3.9 kHz; up to about 1.12, about 1.16, or about 1.18 for a target frequency of about 4 kHz or a frequency band of about 4 kHz to about 7.9 kHz; up to about 1.17, about 1.21, or about 1.23 for a target frequency of about 8 kHz or a frequency band of about 8 kHz to about 15.9 kHz; and up to about 1.19, about 1.25, or about 1.30 for a target frequency of about 16 kHz or a frequency band of about 16 kHz to about 21 kHz. It is to be understood that the foregoing volume adjustments include lower magnitude adjustments below the presented upper limit, such as, for example, multiplying the volume of each target frequency or frequency band expressed above by a factor from about 1 to the presented maximum multiplication factor. Also, the foregoing adjustments ratios are provided as examples and are not intended to limit the scope of the present disclosure.
For instance, while certain multiplication factors or ratios are provided in each of Examples 1-3, it will be understood that any multiplication factors or ratios from any examples can be combined together. For instance, any multiplication factor or ratio of Example 1 can be combined with any multiplication factor or ratio of either or both of Example 2 and 3. Additionally, any multiplication factor or ratio of Example 2 can be combined with any multiplication factor or ratio of either or both of Example 1 and 3.

Alternatively, speaker tuning can be accomplished by multiplication of one or more audio frequencies by a predetermined ratio or multiplication factor. For instance, each audio frequency can be adjusted by a multiplication factor ranging between about 1 and about 1.235 for speakers covered by leather, between about 1 and about 1.115 for speakers covered by polyester, between about 1 and about 1.063 for speakers covered by chenille or velvet, and between about 1 and about 1.037 for speakers covered by tweed or linen. One skilled in the art should appreciate that the foregoing values are provided as an example and are specific to example materials having a particular composition, density, thickness, and weight. As disclosed herein, specific adjustment values are preferably calculated on an individual basis for each upholstery fabric intended to cover a speaker or speaker system to ensure optimal sound quality as the sound is emitted though the selected upholstery fabric.
