Description of Related Art
Dropping an audio speaker often damages the speaker. Speakers with external moving parts are particularly hard to protect from damage caused by falls because protection systems can impede normal use of the speaker (e.g., by impeding access to moving parts). As a result, many people simply do not use a protection system. Some people use a protection system that fails to even attempt to protect the external moving portions, which leaves the speaker vulnerable to damage caused by falls. Thus, there is a need for systems that provide reliable protection from falls.
In some embodiments, speaker protection systems are uniquely configured to enable moving parts to be protected when audio speakers are dropped. Various features work together to absorb impacts from falls. The interaction of these features enable speaker protection systems to be compliant during initial phases of impact and then reduce compliance to avoid “bottoming out” problems, which often lead to speaker damage. Thus, embodiments can enable variable shock absorption with resistance to deformation that increases as the magnitude of the deformation increases. This approach can maximize odds of speakers “surviving” falls from substantial heights (e.g., as defined by U.S. Military Standards such as MIL-STD-810G).
In several embodiments, a speaker protection system is configured to protect an audio speaker device from falls. The system can include a bottom cap coupled to a bottom portion of the speaker device. The bottom cap can be cylindrical and can have a hole that is concentric with an outer cylindrical surface of the bottom cap. A top cap can be coupled to a top portion of the speaker device. The top cap can also be cylindrical (or any other suitable shape). The top cap can have a hole that is concentric with an outer perimeter of the top cap. The top cap can cover at least a portion of a top surface of the speaker device such that the top cylindrical cap is configured to resist downward dislodgement of the top cylindrical cap.
In some embodiments, the top cap is coupled to the bottom cap such that the top cap can rotate relative to the bottom cap. The system can be coupled to the speaker device by inserting a bottom portion of the speaker device into a first cavity of the bottom cap, inserting a top portion of the speaker device into a second cavity of the top cap, and coupling the top cap to the bottom cap (e.g., via a snap fit).
In several embodiments, the system can be removed from the speaker device by decoupling the top cap from the bottom cap, sliding the top cap upward (until it is no longer on the speaker device), and sliding the bottom cap downward (until it is no longer on the speaker device).
In some embodiments, ventilation channels help with heat management and with shock absorption. Ventilation channels can be oriented vertically and can be formed by ribs. Ribs can be radially inward protrusions that are separated by valleys. In some embodiments, the ribs are oriented radially inward around an inward facing cylindrical surface of the top cap and/or the bottom cap.
In several embodiments, the top cap, the bottom cap, and/or the speaker device are concentric. The top cap and the bottom cap can have equal outer diameters. In some embodiments, the top cap has a larger outer diameter than the bottom cap to provide additional shock absorption when the speaker device tips over.
These and other features, aspects, and advantages are described below with reference to the drawings, which are intended to illustrate but not to limit the invention. In the drawings, like reference characters denote corresponding features consistently throughout similar embodiments.

In several embodiments, the speaker device 4 is an Amazon Echo made by Amazon.com, Inc. The speaker device 4 can be a cylinder. Other types of speaker devices 4 can also be used with embodiments of speaker protection systems 2.
Speakers with external moving parts are particularly hard to protect from damage caused by falls because protection systems can impede normal use of the speaker. The Amazon Echo includes a rotating dial (e.g., 130 in
Many embodiments described herein solve this problem via a rotatable coupling 125 that enables a top cap 104 to rotate relative to the bottom cap 100 while the top cap 104 applies a compressive force on the rotating dial 130. The compressive force enable the top cap 104 to rotate the dial 130 in response to a user rotating the top cap 104. The resulting system 2 provide far superior speaker protection than systems that fail to cover the top portion 106 of the speaker 4. In addition, the system 2 preserves access to the functionality of the rotating dial 130 (although indirectly via the top cap 104).
In many embodiments, the top cap 104 can be coupled to the bottom cap 100 by pressing the top cap 104 onto the bottom cap 100. This pressing force can deform portions of the top cap 104 and/or the bottom cap 100 to activate and engage a snap fit. In several embodiments, snap-fits use flexible parts (which can be molded from plastic, rubber, or any suitable material) to form the final assembly by pushing the parts' interlocking components together.
Some embodiments of the system 2 comprise an interlock 110 between the top cylindrical cap 104 and the bottom cylindrical cap 100. The interlock 110 can comprise a downward facing wall 112 of the bottom cylindrical cap 100 that blocks upward movement of the top cylindrical cap 104 relative to the bottom cylindrical cap 100, but does not block rotational movement 119 of the top cylindrical cap 104 relative to the bottom cylindrical cap 100. Thus, the system 2 is configured to enable the top cap 104 to rotate relative to the bottom cap 100 while impeding the top cap 104 from being uncoupled from the bottom cap 100.
As used herein, a vertical direction is oriented along a central axis of the caps. When the top cap is coupled to the bottom cap, downward is a direction from the top cap towards the bottom cap and upward is a direction from the bottom cap towards the top cap. A downward facing wall is oriented within plus or minus 25 degrees of parallel to a central axis of the cap that comprises the downward facing wall. An upward facing wall is oriented within plus or minus 25 degrees of parallel to a central axis of the cap that comprises the upward facing wall.
The caps can be cylindrical. In some embodiments, the caps are not cylindrical, but can be any suitable shape. For example, the caps can have cross sections that are square, rectangle, or hexagonal.
As used herein, an interlock is a structure or set of structures that couple two parts such that the motion or operation of at least one of the parts is constrained by the other part. In some embodiments, interlocks allow two parts to rotate relative to each other, but limit how far apart the two parts can move away from each other. For example, the interlock may prevent the two parts from moving more than 15 millimeters away from each other.
As used herein, “block” refers to a physical relationship between mechanical structures. In many embodiments, the blocking can be overcome by sufficient upward force or downward force to remove the top cap 104 from the bottom cap 100. Referring now to
Similarly, a radially outward protrusion 121 of the bottom cap 100 blocks a radially inward protrusion 123 of the top cap 104 from moving upward (e.g., as indicated by arrow 177). However, applying a sufficient upward force on the top cap 104 will cause portions of the top tap 104 and/or the bottom cap 100 to deform (e.g., elastically) to enable removing the top cap 104 from the bottom cap 100 to facilitate removing the speaker device 4 from the system 2.
In some embodiments, the vertical interlock 110 blocks upward movement of the top cylindrical cap 104 relative to the bottom cylindrical cap 100, but then permits the user to move the top cap 104 upwards relative to the bottom cap 100 to remove the top cap 104 from the bottom cap 100 during disassembly of the system 2.
In several embodiments, the vertical interlock 110 can comprise a downward facing wall 112 of the bottom cylindrical cap 100 that blocks upward movement of the top cylindrical cap 104 relative to the bottom cylindrical cap 100. In these same embodiments, the vertical interlock 110 removably couples the top cylindrical cap 104 to the bottom cylindrical cap 100 such that pulling the top cylindrical cap 104 upward relative to the bottom cylindrical cap 100 can overcome a holding force of the vertical interlock 110, which causes elastic deformation of at least a portion of the top cylindrical cap 104 relative to the bottom cylindrical cap 100 to release the vertical interlock 110.
Another challenge that speakers 4 face is heat management. Speakers 4 can generate a lot of heat, especially during high-volume operation. Several embodiments include ribs 154, 156, 158 to form vents 155, 157 to permit cooling air to flow between the caps 100, 104 and the speaker 4. The ribs 154, 156, 158 also add compliance to the system to improve shock absorption performance. The ribs 154, 156, 158 can provide a lower resistant to deformation than a solid wall (e.g., of rubber) to which the ribs 154, 156, 158 are coupled. Thus, the system 2, can initially deform relatively easily during an impact, and then, the system can having a higher resistance to deformation.
In some embodiments, ventilation channels 155, 157 help with heat management and with shock absorption. Ventilation channels 155, 157 can be oriented vertically and can be formed by ribs 154, 156, 158. Ribs 154, 156, 158 can be thin protrusions that are separated by valleys. Ribs 154, 156 can be less than 7 millimeters wide and can protrude radially inward between 0.5 millimeters and 10 millimeters.
As shown in
Some embodiments use an interference fit. As used herein, the term “interference fit” is used broadly. In several embodiments, an interference fit, also known as a press fit or friction fit, is a fastening (which is often detachable) between two parts which can be achieved by friction after the parts are pushed together.
In some embodiments, an interference fit is when a first part is larger than a second part such that inserting the first part into the second part causes the second part to expand or causes the first part to contract.
Speakers 4 can be far heavier than other electrics (e.g., cellphones). As a result, some prior art system have failed to provide adequate fall protection. The rings 127, 129, and 133 coupled by pillars 131 and radial protrusions 135 provide remarkable shock protection, even for heavy speakers (such as the Amazon Echo). These components work together to provide a unique blend of initial softness (to take the “edge” off the initial impact) followed by increasing resistance to deformation and ultimately robust resilience. As a result, the rings 127, 129, and 133 coupled by pillars 131 and radial protrusions 135 are particularly well-suited to protect the fragile top portion 160 of the Amazon Echo.
As used herein, a surface can be at an angle (between plus or minus 35 degrees) relative to a plane that is perpendicular to the central axis 111 of the system 2 and still face upward or downward. For example, an upward-facing surface can be oriented at an angle of plus or minus 35 degrees relative to the plane that is perpendicular to the central axis 111 of the system 2 and still face upward relative to the central axis 111 of the system 2. A downward-facing surface can be oriented at an angle of plus or minus 35 degrees relative to the plane that is perpendicular to the central axis 111 of the system 2 and still face downward relative to the central axis 111 of the system 2.
As used herein, a protrusion is radially inward even if the protrusion is not directly radially inward. Directly radially inward means directly towards a central axis 111 of the system 2. In some embodiments, features such as ribs 154, 156 protrudes radially inward because they protrude towards a central area of the top cap 104 and/or the bottom cap 100, and yet do not protrude directly radially inward. Ribs 154, 156 can protrude radially inward by protruding into a central cavity of the top cap 104 and/or the bottom cap 100.
Features can protrude radially outward by protruding away from the central area of the top cap 104 and/or the bottom cap 100 without necessarily protruding directly radially outward. In several embodiments, radially outward protrusions 121 protrude outward at an angle relative to a plane that is perpendicular to the central axis 111 of the system 2. Ribs 154, 156 can protrude radially outward by protruding away from a central cavity of the top cap 104 and/or the bottom cap 100.
The bottom cap 100 can include a groove 109 that faces radially outward (e.g., as shown by arrow 181 in
Although many embodiments are described as being cylindrical, not all embodiments are cylindrical. In some embodiments, the bottom cap and the top cap are cubes. In several embodiments, the bottom and top caps have triangular cross-sections. The caps can have any suitable shape.
Many of the embodiments can be molded from silicone. Some embodiments are molded from acrylonitrile butadiene styrene (“ABS”), thermoplastic elastomer (“TPE”), thermoplastic polyurethane (“TPU”), polyurethane (“PU”), and/or polycarbonate (“PC”). In several embodiments, a first material is molded, and then a softer material is overmolded onto the first material. For example, the outer material of caps can be harder than the inner material. In several embodiments, the ribs are overmolded from a softer material than is used to mold exterior portions of the caps.
Textures and surface features (such as ridges) can be molded into external surfaces of caps to make the caps less likely to slip out of people's hands. The cap walls can have any suitable thickness. In some embodiments, the cap walls are at least 0.5 millimeters thick and/or less than 15 millimeters thick.

The system can comprise a vertical interlock 110 (e.g., as illustrated in
The vertical interlock 110 can comprise an upward facing wall 113 of the top cylindrical cap 104. The downward facing wall 112 faces the upward facing wall 113 of the top cylindrical cap 104. Upward movement (e.g., as indicated by arrow 177 in
In some embodiments, the top cap 104 is removably coupled to the bottom cap 100 such that a sufficiently large force can overcome the maximum holding strength of the interlock 110, which causes the interlock 110 to elastically deform, which permits decoupling the top cap 104 from the bottom cap 100, which permits removing the speaker device 4 from the top cap 104 and the bottom cap 100.
Referring now to
The vertical interlock 110 is located indirectly below a rotating dial 130 of the speaker device 4. (
The top cylindrical cap 104 is rotatably coupled to the bottom cylindrical cap 100 by a snap fit 132 comprising a radially outward protrusion 121 and a radially inward protrusion 123 such that at least a portion of the snap fit 132 elastically deforms in response to coupling the top cylindrical cap 104 to the bottom cylindrical cap 100.
The top cylindrical cap 104 comprises a groove 134 that faces radially inward. The bottom cylindrical cap 100 comprises a radially outward protrusion 121 located at least partially in the groove 134. The top cylindrical cap 104 is rotatably coupled to the bottom cylindrical cap 100 by the groove 134 and the radially outward protrusion 121.
The snap fit 132 is located indirectly below a rotating dial 130 of the speaker device 4. The top cylindrical cap 104 comprises a first interference fit with the rotating dial 130. The groove 134 is configured to rotate without contacting a radially outward most surface 136 of the radially outward protrusion 121.
The groove 134 follows a 360 degree path along an inner-facing wall 138 of the top cylindrical cap 104. The radially outward protrusion 121 follows a 360 degree path around a central axis 122 of the bottom cylindrical cap 100.
