The present disclosure generally relates to earpieces and, more particularly, to earpiece retention assemblies.
Earpieces are useful for hearing protection and communication. For example, earpieces may be used to suppress certain sounds, audible frequency bands, or audible frequency functions; enhance certain sounds, audible frequency bands, or audible frequency functions; enable communication with electronic devices, etc. However, securing earpieces adjacent to an ear canal or partially within the ear canal can result in an uncomfortable fit and/or side-of-head-specific earpiece assemblies. For example, conventional earpiece retention devices typically require custom fitting to an individual ear and/or additional components or shaping specific to a particular ear or side (i.e., a left ear or a right ear). As such, conventional earpiece retention devices may be limited for use in one ear (i.e., a left ear or a right ear) and/or may include ear clips or other features that uncomfortably retain an earpiece adjacent to or partially within an ear canal.
In an embodiment, an earpiece retention assembly may include a cable portion pre-formed into an ear loop with a first end coupled to a non-insertion end of an earpiece. The cable portion may be configured to bias the earpiece toward the interior of the ear loop, thus defining a default orientation.
One or more of the following features may be included. The earpiece may be configured to be twisted from the default orientation for insertion into an ear canal, thus defining an insertion orientation. A biasing force between the cable portion and the non-insertion end of the earpiece may be configured to bias the earpiece from the insertion orientation toward the default orientation. The biasing force between the cable portion and the non-insertion end of the earpiece may be configured to retain the earpiece within the ear canal when the earpiece is at least partially inserted into the ear canal. The earpiece may be configured to be twisted from the default orientation for insertion into the ear canal of either ear. The earpiece may be configured to be twisted from the default orientation to an angle ranging from about zero degrees to about one hundred eighty degrees relative to the default orientation when inserting the earpiece into the ear canal of a left ear. The earpiece may be configured to be twisted from the default orientation to an angle ranging from about zero degrees to about negative one hundred eighty degrees relative to the default orientation for insertion into the ear canal of a right ear. A second end of the cable portion may be configured to be coupled to an electronic device. The cable portion includes one or more wires encased in an exterior tubing.
According to another embodiment, an earpiece retention assembly may include a cable portion pre-formed into an ear loop with a first end coupled to a non-insertion end of an electronic earpiece. The cable portion may be configured to elastically bias the electronic earpiece into an orientation substantially parallel to the cable portion when the cable portion is looped over an ear, thus defining a default orientation.
One or more of the following features may be included. The electronic earpiece may be configured to be twisted from the default orientation for insertion into an ear canal, thus defining an insertion orientation. An elastic biasing force between the cable portion and the non-insertion end of the electronic earpiece may be configured to elastically bias the electronic earpiece from the insertion orientation toward the default orientation. The elastic biasing force between the cable portion and the non-insertion end of the electronic earpiece may be configured to retain the electronic earpiece within the ear canal when the electronic earpiece is at least partially inserted into the ear canal. The electronic earpiece may be configured to be twisted from the default orientation for insertion into the ear canal of either ear. The electronic earpiece may be configured to be twisted from the default orientation to an angle ranging from about zero degrees to about one hundred eighty degrees relative to the default orientation when inserting the earpiece into the ear canal of a left ear. The electronic earpiece may be configured to be twisted from the default orientation to an angle ranging from about zero degrees to about negative one hundred eighty degrees relative to the default orientation for insertion into the ear canal of a right ear. A second end of the cable portion may be configured to be coupled to an electronic device. The cable portion may include one or more wires encased in an exterior tubing.
According to yet another embodiment, a method for producing an earpiece retention assembly may include forming a cable portion into an ear loop. The cable portion may be heated at a predefined temperature for a predefined period of time. In one example, the cable portion may be heated at about 80° Celsius for about 20 minutes. A non-insertion end of an earpiece may be coupled to a first end of the cable portion such that the earpiece is elastically biased toward the interior of the ear loop.
One or more of the following features may be included. The cable portion may include one or more wires encased in an exterior tubing.
The details of one or more implementations are set forth in the accompanying drawings and the description below. Other features and advantages will become apparent from the description, the drawings, and the claims.
Like reference symbols in the various drawings indicate like elements.
In general, consistent with the present disclosure, a universal earpiece retention assembly is provided for retaining earpieces within a user's ear; either a left ear or a right ear. For example, and referring generally to
As will be described in greater detail below, a universal earpiece retention assembly may include, but is not limited to, a cable portion pre-formed into an ear loop with a first end coupled to a non-insertion end of an earpiece. The cable portion may be configured to bias the earpiece toward the interior of the ear loop to define a default orientation. Embodiments of the present disclosure may provide a universal (i.e., adaptable to either ear) earpiece retention assembly that comfortably retains an earpiece within a user's ear. In this manner and consistent with the present disclosure, earpieces may be used in either ear and retained with only the twisting or biasing force of the cable portion. Accordingly and in contrast to conventional earpiece retention devices, generic earpieces may be utilized without requiring custom fitting to a user's ear and without additional components or shaping specific to a particular ear (i.e., a left ear or a right ear).
Referring to
In some implementations, cable portion 12 may be pre-formed into an ear loop. As will be discussed in greater detail below and in contrast to conventional earpiece assemblies, earpiece retention assembly 10 may be configured to utilize a universal ear loop to allow earpiece retention assembly 10 to be used in either ear (e.g., a left ear or a right ear). In this manner, earpiece retention assembly 10 may be adapted for either ear.
Cable portion 12 may be pre-formed into an ear loop shape (or any shape) by heating cable portion 12 in a particular shape for a predefined period time at a particular temperature (or range of temperatures) to impart elastic properties to cable portion 12. During the heating and subsequent cooling process, cable portion 12 may develop elastic properties where cable portion 12 has a default shape (i.e., the pre-formed shape of cable portion 12) and, when a force is applied to cable portion 12, cable portion 12 may produce an opposing force to elastically revert cable portion 12 back to the default shape.
In some implementations, cable portion 12 may be pre-formed into an ear loop with a first end (e.g., first end 14) coupled to a non-insertion end of an earpiece (e.g., earpiece 16). An electronic earpiece may include an electrical component configured to be inserted at least partially into an ear canal and configured to perform various auditory operations such as sound amplification, sound attenuation, communication (e.g., as part of a radio system), noise filtering, etc. However, it will be appreciated that non-electronic earpieces may be coupled to first end 14 of cable portion 12 within the scope of the present disclosure. For example, an ear plug or other passive earpiece may be coupled to first end 14 of cable portion 12. In some implementations, the earpiece (e.g., earpiece 16) may include a non-insertion end (e.g., non-insertion end 18 of earpiece 16). Non-insertion end 18 may generally include the end or portion of earpiece 16 that is not inserted into an ear canal. In this manner, non-insertion end 18 may be an externally facing or exposed end of earpiece 16 when earpiece 16 is at least partially inserted into an ear canal.
In some implementations, a second end of the cable portion may be configured to be coupled to an electronic device. As discussed above and in some implementations, earpiece 16 may be at least a portion of an electronic communication system. For example, earpiece 16 may be a portion of a headphone assembly that includes one or more speakers configured to generate sound signals. Earpiece 16 may be electronically coupled via cable portion 12 to a radio system or other sound signal source. In this manner, earpiece 16 may provide sound signals from the electronic device (e.g., a radio, a computing device, etc.) to an ear canal (or adjacent to the ear canal). Accordingly, second end 20 of cable portion 12 may include an adapter for coupling to an electronic device (e.g., a 3.5 millimeter adapter, a 2.5 millimeter adapter, etc.). It will be appreciated that second end 20 of cable portion 12 may include any type of adapter for coupling to an electronic device within the scope of the present disclosure.
In some implementations, the cable portion may be configured to bias the earpiece toward the interior of the ear loop, thus defining a default orientation. As discussed above and in some implementations, cable portion 12 may be pre-formed (i.e., heated and shaped) into an ear loop such that cable portion 12 develops elastic properties where cable portion 12 has a default shape (i.e., the shape of cable portion 12 when no rotational or twisting force is applied to cable portion 12) and, when a rotational force is applied to cable portion 12, cable portion 12 may produce an opposing rotational force to elastically bias cable portion 12 back to the default shape. Referring also to
In some implementations, biasing earpiece 16 toward the interior of the ear loop defined by cable portion 12 may include biasing earpiece 16 into an orientation substantially parallel to the cable portion when the cable portion is looped over an ear, thus defining a default orientation (e.g., default orientation 24). Referring also to
In some implementations, earpiece 16 may be configured to be twisted from the default orientation for insertion into an ear canal, thus defining an insertion orientation. Referring also to
In some implementations, the biasing force between the cable portion and the non-insertion end of the earpiece may elastically bias the earpiece from the insertion orientation toward the default orientation. For example and referring again to
In some implementations, the biasing force between the cable portion and the non-insertion end of the earpiece may be configured to retain the earpiece within the ear canal when the earpiece is at least partially inserted into the ear canal. For example and referring again to
In some implementations, the earpiece may be configured to be twisted from the default orientation for insertion into the ear canal of either ear. Referring again to
In some implementations, the earpiece may be configured to be twisted from the default orientation to an angle ranging from zero degrees to ninety degrees relative to the default orientation when inserting the earpiece into the ear canal of a left ear. Referring again to
In some implementations, the earpiece may be configured to be twisted from the default orientation to an angle ranging from zero degrees to negative ninety degrees relative to the default orientation for insertion into the ear canal of a right ear. As discussed above relative to the insertion of earpiece 16 into the ear canal of a left ear, earpiece 16 may be twisted (e.g., by a user of earpiece retention assembly 10) at an angle ranging from zero degrees (e.g., as shown in
Referring also to
In some implementations, the cable portion may be heated 1304 at about eighty degrees Celsius for about twenty minutes. For example, a mold or other mechanism configured to hold cable portion 12 into the shape of an ear loop may be placed in or on a heating source (e.g., an oven) set to a predefined temperature (e.g., eighty degrees Celsius) for a predefined amount of time (e.g., twenty minutes). In this manner, cable portion 12 may stiffen during the heating process such that cable portion 12 is configured to elastically bias into the ear loop shape (or whatever shape cable portion 12 is heated in). While an example temperature of e.g., eighty degrees Celsius and an example period of time of e.g., twenty minutes for heating cable portion 12 has been provided, it will be appreciated that the predefined heating temperature and predefined heating time may be selected or determined based upon, at least in part, the material of cable portion 12 and the dimensions of cable portion 12. For example, the heating temperature or set of heating temperatures and heating time or set of heating times may be selected or determined for a particular cable portion material and/or for particular dimensions of the cable portion such that cable portion 12 is imparted with elastic characteristics by the heating process.
In some implementations, the cable portion may be cooled at a predefined temperature for a predefined period of time. For example, cable portion 12 may be cooled at a controlled rate (i.e., a predefined temperature or set of temperatures for a predefined period of time) based on the properties (i.e., material, dimensions, etc.) of cable portion 12 to impart elastic characteristics. In some implementations, cable portion 12 may be placed in a cooling device configured to cool cable portion 12 at the predefined rate for the predefined amount of time.
In some implementations, a non-insertion end of an earpiece may be coupled 1306 to a first end of the cable portion such that the earpiece is oriented toward the interior of the ear loop. For example and following the heating of cable portion 12, cable portion 12 may be removed from the heating source and allowed to cool or exposed to controlled cooling. As cable portion 12 cools, first end 14 may be biased or bent toward the interior of the ear loop. In some implementations, earpiece 16 may be coupled 1306 to first end 14 of cable portion 12 such that earpiece 16 is oriented toward the interior of the ear loop formed by cable portion 12. As shown in
In some implementations, coupling 1306 earpiece 16 to first end 14 of cable portion 12 such that earpiece 16 is oriented toward the interior of the ear loop formed by cable portion 12 may include coupling 1306 earpiece 16 into an orientation substantially parallel to cable portion 12 when cable portion 12 is looped over an ear, thus defining a default orientation (e.g., default orientation 24).
