[0075] Detailed Description
[0076] In the following detailed description of the exemplary embodiments, reference is made to the accompanying figures of the drawings for a respirator communications device with universal mounting system which form a part hereof and are shown by illustration of specific embodiments. It is to be understood that other embodiments may be utilized, and structural changes may be made without departing from the scope of the present invention.
[0077] To be effective in a plurality of respirators, the present invention can integrate into multiple types for communication. Also, the communications system is easy to clean and maintain while also being easy to manufacture. The low-cost mounting brackets used in the present invention hold a wireless microphone device on the inside of a respirator. The wearer’s speech is received, processed, and transmitted to a receiver external to the respirator. The mounting brackets are configured to attach to the respirator body as well as form a part of the respirator body. Once the microphone device is configured in the respirator, the wearer can configure the wireless connection to a variety of external devices such as a speaker or a mobile phone.
[0078] FIG. 1 illustrates an exemplary embodiment of the universal microphone device and mounting system 90 of the present invention, in particular the microphone device 100 is configured to be positioned in any of the microphone device brackets 102 shown in the perspective view. The system of the present invention may include any number of brackets, where the brackets are configured to each attach to a specific respirator, but only one universal microphone device 100 may be used in the system, which is especially useful for users of a variety of respirators. Any number of different types of respirators may be included in the system 90, so long as it includes a corresponding microphone device bracket 102 to hold the universal microphone 100. Alternatively, the system 90 could include multiple microphone devices 100, so long as such microphone devices are shaped to attach to certain corresponding microphone device brackets 102, which are configured to attach to corresponding respirators.
[0079] FIG. 2 illustrates the universal system 90 including an exemplary microphone device 100 and a plurality of microphone device brackets 102a-102f of FIG. 1, where each specially designed microphone bracket 102a-102f is attached within its corresponding respirators lOla-lOlg. The microphone device 100 is configured to be positioned within each of the microphone device brackets 102a-102f. The microphone device 100 is releasably attached within each of the microphone device brackets 102a-102f. Each microphone device bracket 102a-102f is specially designed and configured to be positioned within a specific respirator 10 la-101g. The microphone device bracket 102a-102f is releasably attached within a specific respirator 101a-101 g, respectively.
[0080] In some embodiments, the microphone device bracket 102 is positioned in the respirator 101 initially, then the wearer positions the microphone device 100 within the microphone device bracket 102 afterwards. In other embodiments, the microphone device 100 is first installed within the microphone device bracket 102, and then the microphone device 100 and microphone device bracket 102 are positioned together within the respirator 101. In yet other embodiments, the microphone device bracket 102 is configured to be positioned partially within the respirator 101 and partially exposed to unfiltered air external the respirator 101. In some embodiments, the microphone device bracket 102 is configured to attach to the filter inlet of the respirator. In some embodiments, the microphone device bracket 102 is configured to attach to the respirator body. In some embodiments, the microphone device bracket forms a part of the respirator body.
[0081] FIG. 3A illustrates an exemplary embodiment of the microphone device 100 used in a plurality of microphone device brackets 102 and respirators 101. The microphone device 100 comprises an illuminated power button 104, which allows the user to turn the microphone device 100 on or off. In some embodiments, the illuminated power button 100 may be used to select settings for the microphone device 100. The microphone port 106 allows acoustic input from the wearer through the microphone device top face 120. For the illustrated embodiment, a first male detent 108 and a second male detent 109 may be used to secure the microphone device 100 in the various microphone device brackets 102. The detents 108, 109 may comprise a helical shape to allow a wearer to twist the microphone device 100 in the desired position within the bracket 102. The first male detent 108 and second male detent 109 are located on opposite sides of the microphone device 100. The male detent notch 110 provides feedback to the wearer that the microphone device 100 is in the proper position within the microphone device bracket.
[0082] FIG. 3B is a side view of the microphone device 100 showing a detent notch 110 and where the first male detent 108 is helical. The first male detent 108 helical shape allows the wearer to twist the device 100 into a desired position. The detent notch 110 provides feedback to the wearer that the microphone device 100 is in the desired position within the microphone device bracket 102. The preferred position of the microphone device 100 is configured such that the microphone device 100 bottom face 118 opposes the wearer. The microphone device top face 120 is positioned facing the wearer. This position has two advantages. Since the microphone port 106 resides on the top face 120 of the microphone device 100, the microphone port 106 picks up the maximum acoustic energy from the speech of the wearer if the top face 120 faces the wearer, being closer to the user’s mouth. At the same time, the top face 120 faces away from the body and exhalation valve of the respirator in this position. As a result, the microphone port 106 detects a minimum acoustic energy from reverberations caused by vibrations in the respirator body and exhalation valve during speech, leading to a stronger and clearer speech signal because it is deteriorated less by the reverberations from the respirator. The first male detent 108 only allows one configuration of the microphone device within the microphone device bracket. Although one angle is shown, the first male detent 108 may be configured to have any number of different angles of rotation.
