Abstract
A refrigerator appliance (100) defines a vertical direction, a lateral direction, and a transverse direction and includes a cabinet (102) defining a chilled chamber (122,124), a door (128) being rotatably mounted to the cabinet (102) to provide selective access to the chilled chamber (122,124), a control panel (160) mounted to a front of the door (128), a dispensing assembly (140) mounted to the door (128) and defining a dispenser recess (142), wherein a speaker void (228) is defined within the dispenser recess (142), and a speaker assembly (200) mounted within the door (128) behind the control panel (160), the speaker assembly (200) comprising a speaker housing (202) mounted within the speaker void (228), the speaker housing (202) defining a speaker enclosure and at least one housing alignment feature (250).
Description
The present subject matter relates generally to refrigerator appliances, and more particularly to sound systems for refrigerator appliances.
Refrigerator appliances generally include a cabinet that defines one or more chilled chambers for receipt of food articles for storage. Typically, one or more doors are rotatably hinged to the cabinet to permit selective access to food items stored in the chilled chamber. Further, refrigerator appliances commonly include ice making assemblies mounted within an icebox on one of the doors or in a freezer compartment. The ice is stored in a storage bin and is accessible from within the freezer chamber or may be discharged through a dispenser recess defined on a front of the refrigerator door.
Conventional refrigerator appliances may include one or more speakers or audible chime indicators for communicating operating statuses to a consumer. For example, if the consumer fails to fully shut the refrigerator door, a chime may sound to notify the consumer. However, conventional refrigerator audio devices are small, low power devices that have limited operating frequencies and poor audio quality. Moreover, space restrictions within confined spaces of conventional refrigerator appliances limit the ability to use larger, higher quality speakers, and result in various challenges in routing wiring to the location, or manufacturing concerns. Accordingly, conventional refrigerators have limited audio capabilities. Moreover, conventional audio devices are positioned in the refrigerator such that the generated sound has poor quality, e.g., particularly at high and low frequencies.
Accordingly, a refrigerator appliance with improved audio features would be desirable. More particularly, a high quality, high power speaker assembly for use within a dispensing assembly of a refrigerator appliance would be particularly beneficial.

Referring now generally to FIGS. 1 through 9, a speaker assembly 200 that may be used with refrigerator appliance 100 will be described according to exemplary embodiments of the present subject matter. Specifically, as will be described in more detail below, speaker assembly 200 and dispenser recess 142 are designed to achieve a desired or targeted acoustic response from a speaker positioned within dispenser recess 142. Notably, as explained above, conventional refrigerator speakers or audio devices are small, low-power, and limited frequency devices incapable of providing rich audio content as facilitated by a speaker assembly 200. Moreover, conventional refrigerator appliances have limited space for receiving higher-quality speakers and have speakers oriented in a manner that generates less than desirable audio response or sound quality.
According to an example embodiment, speaker assembly 200 may generally include a speaker box or speaker housing 202 that contains a speaker driver 204 including a sound producing speaker cone (not shown) . According to the illustrated embodiment, speaker assembly 200 is positioned within dispenser recess 142 and is covered up by control panel 160. Specifically, speaker housing 202 may be concealed by control panel 160 for improved aesthetics. In addition to aesthetics, when control panel 160 is in place it further modifies the resulting audio output shaping it into the more desired response. In addition, according to an example embodiment, speaker assembly 200 and the sound producing speaker cone may generally be directed downward along the vertical direction V into dispenser recess 142.
Notably, the downward orientation of speaker assembly 200 may generate some audio issues particularly at boundary frequencies (e.g., such as reduced high/low
frequency output or performance) . Accordingly, aspects of the present subject matter are generally directed to an improved design of dispenser recess 142 in conjunction with the high-quality speaker assembly 200 to produce a synergistic effect with improved overall audio quality across the entire audible spectrum (e.g., between 20 Hz to about 20 kHz) . Although speaker assembly 200 is illustrated and described herein as including a single speaker, it should be appreciated that speaker assembly 200 may include any suitable number, type, configuration, and positioning of speakers while remaining within the scope of the present subject matter.
Specifically, according to the illustrated embodiment, dispenser recess 142 may be specifically designed to facilitate an improved acoustic response from speaker assembly 200. In this regard, the geometry of dispenser recess 142 may act as a parabolic reflector, a sounding board, or a noise reflector particularly suited for improving the frequency response, recovering some of the high frequency output that would normally be lost by orienting the speaker downward and 90 degrees from the axis of the listener, etc. Specifically, according to an example embodiment, dispenser recess 142 may generally be defined by a back wall 210, sidewalls 212, and two arcuate corners 214 that join back wall 210 to sidewalls 212.
Specifically, as illustrated, back wall 210 may generally be a flat wall extending in a plane defined by the vertical direction V and the lateral direction L. Similarly, sidewalls 212 may generally be flat walls extending in a plane defined by the vertical direction V and the transverse direction T. Arcuate corners 214 may wrap around an axis defined by the vertical direction V to join back wall 210 to sidewalls 212. Notably, the orientation of speaker assembly 200 in conjunction with the geometry of dispenser recess 142 may provide a particularly suitable sound response.
Notably, the positioning of speaker assembly 200 within dispenser recess 142 may be important for determining the appropriate sound response of speaker assembly 200. For example, as illustrated, refrigerator appliance 100 may include a separator panel 220 that divides dispenser recess 142 into a dispensing region 222 and a mechanical compartment 224. In this regard, separator panel 220 may generally extend within a horizontal plane (e.g., defined by the lateral direction L and the transverse direction T) . Dispensing region 222 may be positioned below separator panel 220, e.g., and may include actuating mechanism 148 and a space for receiving
cups. By contrast, mechanical compartment 224 may be positioned above separator panel 220 and may be covered by control panel 160. Speaker assembly 200 may be positioned within mechanical compartment 224 and separator panel 220 may define a plurality of apertures 226 through which sound may pass into dispensing region 222.
As best illustrated in FIGS. 4 through 9, dispenser recess 142 may generally define a speaker void 228 and speaker assembly 200 may be carefully designed to fit within speaker void 228 while optimizing audio output of speaker assembly 200. In this regard, speaker void 228 may generally be defined by back wall 210, sidewalls 212, arcuate corners 214, control panel 160, separator panel 220, and/or an ice dispensing funnel 230 (e.g., within mechanical compartment 224) . Notably, due to the size restrictions within dispenser recess 142, it may be desirable to maximize the speaker assembly 200 within speaker void 228 for improved sound output. Accordingly, aspects of the present subject matter are directed to a speaker housing 202 and speaker assembly 200 that maximizes speaker performance for the given speaker void 228.
In this regard, for example, speaker housing 202 may generally be defined by a front wall 232, a rear wall 234, a bottom wall 236, a top wall 238, and a plurality of sidewalls 240. The spacing, geometry, angle, and shape of walls 232-240 may be carefully designed or ideal acoustic sizing, reduced vibration, improved assembly, and improved durability of speaker housing 202. For example, walls 232-240 may fill the entire speaker void 228 and may improve manufacturability, as described in more detail below according to example embodiments.
Example, speaker housing 202 may define at least one housing alignment feature 250. In general, housing alignment features 250 may include any suitable geometries, bosses, protrusions, recesses, or extensions to facilitate proper and consistent installation of speaker housing 202. For example, as illustrated in FIGS. 6 through 9, housing alignment feature 250 may include an alignment geometry or recess 252 for engaging a complementary protrusion within dispenser recess 142. For example, alignment recess 252 may be defined within top wall 238 of speaker housing 202 and may be configured for engaging a fastener or alignment feature defined on ice dispensing funnel 230 or a protruding feature within dispenser recess 142.
In addition, as shown for example in FIG. 7, housing alignment feature 250 may include a protruding leg 254 that is received within a complementary recess defined on separator panel 220 or ice dispensing funnel 230. In this manner, an installation technician may slide protruding leg 254 into the complementary recess to ensure accurate and repeatable positioning of speaker housing 202. It should be appreciated that other alignment and installation geometries are possible and within the scope of the present subject matter.
According to still other example embodiments, as illustrated in FIGS. 6 and 7, housing alignment feature 250 may include a threaded boss 256 defined through bottom wall 236 of dispenser housing 202. Threaded boss 256 may be configured for receiving a mechanical fastener that passes through separator panel 220 for securing speaker housing 202 within dispenser recess 142. Notably, alignment of alignment recess 252 and protruding leg 254 may properly position speaker housing 202 such that threaded boss 256 is positioned over an attachment aperture defined in separator panel 220 (e.g., such that a mechanical fastener may pass therethrough into threaded boss 256) .
As illustrated schematically in FIG. 7, speaker assembly 200 may further include one or more pads, cushions, or vibration dampeners 258 positioned on speaker housing 202 for reducing vibrations, e.g., particularly at locations where speaker housing 202 is contacting other components or surfaces. According to the illustrated embodiment, vibration dampener 258 is positioned within alignment recess 252 to prevent vibration-related noise due to contact between alignment recess 252 and ice dispensing funnel 230. However, it should be appreciated that vibration dampeners 258 may be used on other locations of speaker housing while remaining within the scope of the present subject matter.
Referring now specifically to FIGS. 6 and 7, speaker housing 202 may further define at least one wiring retention feature 260. For example, wiring retention feature 260 may be a clip, groove, or other attachment point sized to receive a bundle of wires or a wiring connector. In this manner, an installation technician may install the wiring harness into the wiring retention feature 260 while installing speaker assembly 200. This wiring harness may remain within wiring retention feature 260 for
the lifetime of speaker assembly 200, thereby reducing undesirable vibrations, rubbing, or wear on the wires.
In addition, dispensing assembly 140 may include a water line 270 passing through dispenser recess 142 and speaker housing 202 may define a water line support surface 272. In general, water line 270 is seated on water line support surface 272, which is designed to minimize vibrations and provide a compact and efficient routing of water line 270, e.g., thereby preventing kinks, rubbing, vibrations, etc. Although an example geometry is illustrated, it should be appreciated that this geometry may vary while remaining within the scope of the present subject matter.
As illustrated in FIGS. 4 through 7, speaker assembly 200 may further include one or more passive radiator elements 280. In general, passive radiator elements 280 may be positioned on or within speaker housing 202 to improve the acoustics of speaker assembly 200 (e.g., by boosting low frequency output of speaker assembly 200) . For example, as illustrated, speaker housing 202 may define one or more radiator apertures 282 and a support flange 284 that surrounds each of the radiator apertures 282 for receiving the passive radiator elements 280. According to the illustrated embodiments, passive radiator elements 280 include an acoustic diaphragm 286 (e.g., a rubber or metal diaphragm) positioned over the radiator apertures 282 and connected to the support flange 284 through a resilient border 288 (e.g., formed from rubber) . Other suitable acoustic radiator constructions are possible and within the scope of the present subject matter.
Notably, speaker assembly 200 may generally have a larger power than conventional refrigerator audio indicators. For example, speaker assembly 200 may have a power level that is greater than 3 watts, greater than 5 watts, or greater, e.g., such as between about 6 and 8 watts. In addition, speaker assembly 200 may be designed to generate a frequency range over the entire audible spectrum, e.g., between about 20 Hz and 20 kHz. For example, speaker assembly 200 may have a frequency range of between about 100 Hz and 18 kHz.
As explained herein, aspects of the present subject matter are generally directed to a compact speaker enclosure designed to fit in the refrigerator door dispenser recess area wherein the speaker is oriented such that the sound-producing cone faces down into the dispenser area. A top surface of the speaker enclosure may
be designed to fit a passive radiator. The resulting speaker is capable of producing sound at a reasonable listening level (e.g., 75-77 dB SPL) with a low-frequency cutoff of around 140 Hz. The design may also incorporate features for routing and securing wiring to control and prevent vibration. Additionally, a recessed geometry boss may also be present that pushes the speaker down to minimize vibration.
