Description

[0001] CONFIGURATION AND INDICATOR FEEDBACK CAPABILITIES OF A MICROPHONE DEVICE MOUNTING BRACKET SYSTEM

[0002] Background

[0003] A well-known problem of respirators in the market is that the wearer’s speech is unclear. The main reason for this is that respirators muffle speech and prevent lip reading. At medium levels of ambient noise, the wearer will often struggle to provide speech at the level and clarity to communicate productively and safely. The circumvent this, wearer’s will often take off their masks to communicate in hazardous environments or stop their work to go to a non-contaminated place to communicate.

[0004] Some previous respirators offer passive speech diaphragms to improve speech intelligibility such as in the 3M™ Secure-Click™ HF800 half-facepiece, FF400 / 800 fullfacepieces and 3M™ Scott™ full-facepieces commercially available from 3M Company based in St. Paul.

[0076] Detailed Description

[0077] 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.

[0078] 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.

[0079] Figure 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.

[0080] Figure 2 illustrates the universal system 90 including an exemplary microphone device 100 and a plurality of microphone device brackets 102a-102f of FIGURE 1, where each specially designed microphone bracket 102a-102f is attached within its corresponding respirators 101a- 101g. 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 lOla-lOlg, respectively.

[0081] 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.

[0082] Figure 3 A 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.

[0083] Figure 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.

[0084] Figures 4A and 4B are perspective views of the bottom portion 105 and the top portion 107 of a microphone device housing 103, respectively. The first male detent 108, second male detent 109, and the detent notches 110 are preferably located on the bottom portion 105 of the microphone device housing 103. The battery charging port 112 in the housing 103 allows a wearer to charge the microphone device 100. In some embodiments, the battery charging port 112 contributes to proper orientation of the microphone device housing. The printed circuit board assembly fixture 114 secures the circuit board in position. The microphone device top face 120 includes at least a microphone port 106 and a power button 104.

[0085] Figure 5 is a top view of a printed circuit board assembly 150. The printed circuit board assembly 150 includes a battery charging port 152 and a battery 156. A moisture sealing membrane 153 protects the microphone port 155 from moisture and water. The light emitting diodes 154 indicate a status to the wearer and in some embodiments illuminate the power button 104.

[0086] Figure 6 is convenient for a close-up view of a detent notch 110 indicated in the area of Figure 6A. The first male detent 108 curves to create the detent notch 110 forming a rounded notch face 116. This design is convenient for locking the microphone device 100 into its microphone device bracket 102 as explained in more detail relative to Figures 14A and 14B.

[0087] Figures 7A-7D illustrate one embodiment of the microphone device bracket 102a useful for holding the microphone device 100 to form system 90 for respirators 101. Specifically, Figure 7A and 7B illustrate a microphone device bracket 102a for reusable respirator 101a, which is a type FF-400, illustrated in Figures 7G and 7H. The microphone device bracket 102a includes microphone device position positioners 202 which assist the microphone device 100 to be positioned properly within the microphone device bracket 102a. The microphone device bracket 102 also includes a plurality of microphone device bracket 102 respirator attachments 204, which allow the microphone device bracket 102 to attach and detach from a part of the respirator body, and in essence become part of the respirator body. The bracket seal retainer flange 206 assists in creating an airtight seal between the microphone device bracket 102 and a respirator 101. A second female detent 209 is shown on the microphone device bracket 102. The second female detent 209 preferably includes a female detent notch 210. In some embodiments the female detent may be in another location. The microphone device bracket second side 220 comprises a bracket tab 222 preferably located across the middle of the second side 220. The microphone device bracket second side 220 is located outside of the respirator breathing cavity and exposed to unfiltered air. An example of a breathing cavity 516 is illustrated in Figure 13B . The bracket tab 222 is designed to allow the wearer to easily grasp the microphone device bracket 102a.
