Mechanical design for wireless microphone

Abstract

Mechanical design techniques for constructing a wireless microphone including an outer housing having an outer opening, an inner housing having an inner opening, an ECM device, a rubber cover, a waterproof mesh, and a metal mesh. And the ECM device with a rubber cover is positioned in the inner opening of the inner shell. The waterproof net and the metal net are located in the outer opening of the outer shell. The top air cavity includes an empty space between the top surface of the ECM device and the outer opening of the outer housing. Since the waterproof net and the metal net protect the ECM device from water, debris, and wind, the top air cavity may be formed to be shallower than conventional wireless microphones. Compared with a traditional deep top air cavity, the shallow top air cavity can provide better frequency response performance for audio captured by the ECM device.

Description

Technical Field

[0001] The various implementation schemes generally involve wireless microphones, and more specifically, the mechanical design for wireless microphones. Background Technology

[0002] Wireless microphone systems (WMS) are essential products in both professional and personal audio fields. A typical audio WMS setup involves pairing a transmitter (microphone) and a receiver configured for wireless communication. The transmitter (microphone) captures audio sounds from the environment and transmits the audio data wirelessly to the paired receiver. Microphones implemented in wireless microphone systems typically include electret condenser microphone (ECM) devices. WMS systems are typically implemented in outdoor environments. To enable outdoor use, conventional microphones often place the ECM device deep within the microphone housing, creating a deep air cavity on top of the ECM device between the ECM device and an opening (pickup hole) in the top of the microphone housing. This deep air cavity in conventional microphones provides some protection for the sensitive ECM device from environmental factors such as debris and wind.

[0003] One potential drawback of conventional microphones is that the deep air cavity above the ECM device typically degrades its audio performance. Specifically, in terms of both the audio captured by the ECM and the audio data transmitted to the receiver, a deeper air cavity generally provides a worse frequency response than a shallower one. Another potential drawback of conventional microphones is that while the deep air cavity can offer some protection against debris and wind, conventional microphones typically do not protect the ECM from water or other liquids.

[0004] As mentioned above, a more efficient mechanical design for wireless microphones is needed. Summary of the Invention

[0005] In various embodiments, a wireless microphone includes: an outer housing having an external opening; an inner housing having an internal opening located below the external opening of the outer housing; an electret condenser microphone (ECM) device assembled within the internal opening of the inner housing; a waterproof mesh assembled above the ECM device and located within the external opening of the outer housing; and a metal mesh assembled above the waterproof mesh and located within the external opening of the outer housing.

[0006] Another implementation provides a wireless microphone system and a method for manufacturing the wireless microphone described above.

[0007] At least one technical advantage of the disclosed technology compared to existing technologies lies in the implementation and construction of a mechanical design for the wireless microphone, which allows for a shallower air cavity above (top) the ECM device compared to conventional wireless microphones. The "shallow" top air cavity provided by the disclosed technology offers better frequency response performance in terms of both the audio sound captured by the ECM device and the audio data transmitted to the receiver of the wireless microphone system compared to the deep top air cavities commonly found in conventional wireless microphones. Other technical advantages of the disclosed technology compared to existing technologies include the ability of the wireless microphone to protect the ECM device from debris, dust, moisture, shock, and vibration. These technical advantages provide one or more technological improvements over existing methods. Attached Figure Description

[0022] In the following description, numerous specific details are set forth to provide a more comprehensive understanding of the various embodiments. However, it will be apparent to those skilled in the art that the inventive concepts can be practiced without one or more of these specific details. As used herein, the term "identical or similar" in relation to numerical values ​​such as size or ratio means that the numerical values ​​are identical or substantially identical, and any variation in the numerical values ​​is nominal. As used herein, the various components of the microphone are placed or positioned within the microphone in a specific manner, indicating that the various components are constructed, configured, or assembled in a specific way within the microphone described herein.

[0023] Figure 1 This is a block diagram of a wireless microphone system 101 configured to implement one or more aspects of various implementation schemes. As shown, the wireless microphone system 101 includes, but is not limited to, a wireless microphone 100, a paired receiver 150, and a wireless communication channel 170. The wireless communication channel 170 may include any technically feasible wireless communication or information channel that allows data exchange, such as a wireless (Wi-Fi) network, a personal area network (such as Bluetooth, wireless USB, IrDA, etc.), a wide area network (WAN), a local area network (LAN), and / or the Internet. In other implementations, the wireless microphone 100 communicates with the receiver 150 via radio frequency, wherein the wireless microphone 100 transmits modulated audio signals via radio frequency from a predefined frequency band through a radio frequency antenna.

[0024] The wireless microphone 100 includes a transmitter configured to capture audio sounds (such as speech) from the environment and transmit audio data representing the captured audio sounds to a paired receiver 150 via a wireless communication channel 170. The receiver 150 communicates with the wireless microphone 100 via the wireless communication channel through a wireless communication module of the wireless microphone 100. Specifically, the receiver 150 is configured to wirelessly receive audio data from the wireless microphone 100 and process the audio data to generate an audio signal output. The receiver 150 may include or be connected to an audio output device (not shown), such as a speaker system, to play the audio signal output. The receiver 150 may also include or be connected to an audio recording device (not shown), such as a digital or analog recorder, to record the audio data and / or the audio signal output.

[0025] Figure 2 A front view / top view of an exemplary wireless microphone 100 according to various embodiments is shown. Figure 3 A rear / right view of an exemplary wireless microphone 100 according to various embodiments is shown. Figures 2 to 3 As shown, the wireless microphone 100 includes, but is not limited to, a housing 200 having a front side 210, a top side 220, a bottom side 225, a right side 230, and a rear side 260. The housing 200 has an associated height measurement (shown as "H"). As used herein, "height of housing 200" refers to the highest portion of housing 200 from the bottom side 25 to the top side 220 (maximum height of housing 200).

[0026] The diagram also shows a power button 240 on the right side 230 of the housing 200 of the wireless microphone 100, an external opening 250 in the top 220, and a clip 270 on the rear side 260. The user presses the power button 240 to activate / start the wireless microphone 100. In some embodiments, pressing the power button 240 causes the ECM device to begin capturing audio sound, and the wireless communication module begins transmitting audio data representing the audio sound to the receiver 150 via the wireless communication channel 170. The external opening 250 in the top 220 of the housing 200 includes a sound pickup aperture that allows the ECM device (discussed below) to capture audio sound from the environment. Figures 2 to 3 In the example, a metal mesh (discussed below) is inserted into the outer opening 250 of the outer casing 200.

[0027] Figure 4An exploded view of an exemplary wireless microphone 100 according to various embodiments is shown. As shown, the wireless microphone 100 includes, but is not limited to: a front side 210 of a housing 200, a wireless communication module 410, a power supply 420, an inner housing 430 having an inner opening 440, a rear side 260 of the housing 200, and a clip 270 attached to the rear side 260 of the wireless microphone 100. The power supply 420 may include a battery pack that powers the wireless microphone 100. The wireless communication module 410 is coupled to the power supply 420 and configured to wirelessly communicate with a receiver 150 via a wireless communication channel 170. For example, the wireless communication module 410 may include a Bluetooth module, a network interface card (NIC), a modem, or any other type of module that wirelessly communicates with the receiver 150.

[0028] like Figure 4 As shown, the wireless microphone 100 also includes, but is not limited to, an electret condenser microphone (ECM) device 400, a rubber cover 404, a waterproof mesh 402, and a metal mesh 406, which are respectively housed within the outer casing 200 and / or the inner casing 430. The ECM device 400 includes a microphone based on an electrostatic capacitor. When the wireless microphone 100 is assembled, the outer casing 200 completely encloses the various wireless communication modules 410, the power supply 420, the inner casing 430, the ECM device 400, the rubber cover 404, the waterproof mesh 402, and the metal mesh 406. Notably, when the wireless microphone 100 is assembled, the outer casing 200 completely encloses the inner casing 430, and the inner opening 440 of the inner casing 430 is located directly below the outer opening 250 of the outer casing 200.

[0029] The external opening 250 in the top side 220 of the outer casing 200 (e.g.) Figures 2 to 3 The combination of the ECM device 400 (shown) and the inner opening 440 of the inner housing 430 can define and / or form an integral cavity (discussed below). In some embodiments, the ECM device 400, rubber cover 404, waterproof mesh 402, and metal mesh 406 are each located within the integral cavity. In these embodiments, the integral cavity also includes, but is not limited to, an empty air cavity located on top (above) the ECM device 400, referred to herein as the "top air cavity". In some embodiments, the height of the top air cavity extends from the top surface of the ECM device 400 to the outer opening 250 in the housing 200. In other embodiments, the height of the top air cavity extends from the top surface of the ECM device 400 to the waterproof mesh 402. In still other embodiments, the height of the top air cavity extends from the top surface of the ECM device 400 to the metal mesh 406.

[0030] Figure 5 An exploded close-up view of the top portion of an exemplary wireless microphone 100 according to various embodiments is shown. Specifically, Figure 5A close-up view is shown of the ECM device 400, rubber cover 404, waterproof mesh 402, metal mesh 406, inner opening 440 of inner housing 430, and wire 510 connecting the ECM device 400 to power supply 420 (not shown). When assembling the wireless microphone 100, the rubber cover 404 is fitted over the ECM device 400 to partially enclose it, and the ECM device 400 with the rubber cover 404 is positioned / assembled inside the inner opening 440 of inner housing 430. When assembling the wireless microphone 100, the waterproof mesh 402 and metal mesh 406 are located inside the outer opening 250 of outer housing 200, thus the outer opening 250 of outer housing 200 is directly above the inner opening 440 of inner housing 430.

[0031] Figure 6 A front sectional view of the top portion of an exemplary wireless microphone 100 according to various embodiments is shown. Figure 7 A side sectional view of the top portion of an exemplary wireless microphone 100 according to various embodiments is shown. Figures 6 to 7 As shown, the wireless microphone 100 includes an outer housing 200 having an outer opening 250, an inner housing 430 having an inner opening 440 (located directly below the outer opening 250), an ECM device 400, a rubber cover 404, a waterproof mesh 402, a metal mesh 406, and an integral cavity 600 including a top air cavity 650.

[0032] A rubber cap 404 partially encloses the ECM device 400 to provide shock and vibration protection for the ECM device 400 by isolating (decoupling) it from the housing 200 and the inner housing 430. It is important to note that the rubber cap 404 does not completely enclose the top surface of the ECM device 400 (i.e., the surface / side of the ECM device 400 facing the external opening 250 of the housing 200). The rubber cap 404 only partially encloses the top surface of the ECM device 400 to allow the ECM device 400 to properly capture audio sounds from the environment. As shown, the ECM device 400 and the rubber cap 404 are positioned / assembled within the internal opening 440 of the inner housing 430.

[0033] As shown in the figure, a waterproof mesh 402 and a metal mesh 406 are located above the ECM device 400 and within the external opening 250 of the housing 200. The metal mesh 406 can be positioned / assembled flush with the housing 200, surrounding the external opening 250 of the housing 200. The waterproof mesh 402 can be positioned / assembled below the metal mesh 406 and closer to the ECM device 400 than the metal mesh 406. In some embodiments, the waterproof mesh 402 is attached to and in complete contact with the metal mesh 406. In other embodiments, the waterproof mesh 402 is not attached to and does not in complete contact with the metal mesh 406, and a small gap exists between the waterproof mesh 402 and the metal mesh 406. The waterproof mesh 402 protects the ECM device 400 from dust and water / liquids, while the metal mesh 406 protects the ECM device 400 from debris and other solid particles. The combination of the metal mesh 406 and the waterproof mesh 402 provides wind protection for the ECM device 400. Because the waterproof mesh 402 and the metal mesh 406 provide various protections, the top air cavity 650 above the ECM device 400 can be shallower (lower in height) compared to conventional wireless microphones, as discussed below.

[0034] In some embodiments, the combination of the external opening 250 of the housing 200 and the internal opening 440 of the inner and outer housings 430 defines and / or forms an integral cavity 600 (shown in dashed boxes) within the wireless microphone 100. The integral cavity 600 includes a top air cavity 650 and contains various components of the wireless microphone 100. Various components of the wireless microphone 100 that can be positioned / assembled within the integral cavity 600 include an ECM device 400, a rubber cover 404, a waterproof mesh 402, and a metal mesh 406. The top air cavity 650 within the integral cavity 600 includes an empty space that does not contain any components of the wireless microphone 100 and is located above the top surface of the ECM device 400 between the ECM device 400 and the external opening 250 of the housing 200. In some embodiments, the top air cavity 650 includes the empty space between the top surface of the ECM device 400 and the external opening 250 of the housing 200. In some embodiments, the top air cavity 650 includes the empty space between the top surface of the ECM device 400 and the waterproof mesh 402. In other embodiments, if the waterproof mesh 402 is not implemented, the top air cavity 650 includes the empty space between the top surface of the ECM device 400 and the metal mesh 406.

[0035] The height of the top air cavity 650 extends from the top surface of the ECM device 400 toward the external opening 250 of the housing 200. In some embodiments, the height of the top air cavity 650 is measured using a line 610 perpendicular to the top surface of the ECM device 400, originating from the center point of the top surface of the ECM device 400 and extending toward the external opening 250 of the housing 200 (referred to herein as vertical line 610). In the exemplary wireless microphone 100, the ECM device 400 has a cylindrical volume shape, and the top surface of the ECM device 400 includes a circle with a center point. In other embodiments, the ECM device 400 has different types of volume shapes, and the top surface of the ECM device 400 includes different types of geometry with a center point. In some embodiments, the top air cavity 650 has a height, measured along vertical line 610, from the center point of the top surface of the ECM device 400 to the external opening 250 of the housing 200. In other embodiments, the top air cavity 650 has a height, measured along vertical line 610, from the center point of the top surface of the ECM device 400 to the waterproof mesh 402. In yet another embodiment, if the waterproof mesh 402 is not implemented, the top air cavity 650 has a height, measured along vertical line 610, from the center point of the top surface of the ECM device 400 to the metal mesh 406.

[0036] The width of the top air cavity 650 can be largely determined based on the width of the ECM device 400 (shown as "W"). As used herein, the "width" of the top air cavity 650 refers to the widest portion of the top air cavity 650 (the maximum width of the top air cavity 650). As used herein, the "width" of the ECM device 400 refers to the widest portion of the ECM device 400 (the maximum width of the ECM device 400). In the exemplary wireless microphone 100, the ECM device 400 has a cylindrical volume shape, and the width of the ECM device 400 includes the diameter of the cylindrical volume shape.

[0037] As discussed above, the top air cavity 650 in the exemplary wireless microphone 100 can be shallower / shorter compared to conventional wireless microphones. Specifically, the height of the top air cavity 650 in the exemplary wireless microphone 100 can be a fraction of the width of the top air cavity 650. In some embodiments, the ratio of the height to the width of the top air cavity 650 is in the range of 1 / 6 to 1 / 2. In other embodiments, the height of the top air cavity 650 can be a fraction of the width of the ECM device 400. In some embodiments, the ratio of the height of the top air cavity 650 to the width of the ECM device 400 is in the range of 1 / 6 to 1 / 2. In yet another embodiment, the height of the top air cavity 650 can be the height of the housing 200 (e.g., Figures 2 to 3(as indicated by "H" in the figure). In some embodiments, the ratio of the height of the top air cavity 650 to the height of the housing 200 is in the range of 1 / 20 to 1 / 10.

[0038] The shallower top air cavity 650 provided by the mechanical design of the disclosed exemplary wireless microphone 100 offers better frequency response performance in terms of both the audio sound captured by the ECM device 400 and the audio data transmitted to the receiver 150 of the wireless microphone system 101, compared to the deeper top air cavity commonly found in the mechanical designs of conventional wireless microphones. Specifically, the shallower top air cavity 650 in the disclosed mechanical design of the exemplary wireless microphone 100 provides a flatter frequency response in both the captured audio sound and the transmitted audio data, thereby achieving better sound quality and clearer speech and sound reproduction than achievable through the mechanical designs of conventional wireless microphones.

[0039] Figure 8 A side sectional view of an alternative embodiment of the wireless microphone 100 according to various implementations is shown. Figure 8 The alternative embodiments shown depict a top air cavity 650 with the shortest possible height. In these embodiments, components of the wireless microphone 100 are positioned such that at least a portion of the rubber cover 404 contacts at least a portion of the waterproof mesh 402. For example, a portion of the top surface of the rubber cover 404 may contact the bottom surface of the waterproof mesh 402. Figure 8 In one example, the entire top surface of the rubber cover 404 is in contact with the waterproof mesh 402. However, because of the empty top air cavity 650 between the waterproof mesh 402 and the ECM device 400, the entire waterproof mesh 402 does not contact the top surface of the rubber cover 404. In another embodiment, if the waterproof mesh 402 is not implemented, the components of the wireless microphone 100 are positioned such that at least a portion of the rubber cover 404 is in contact with at least a portion of the metal mesh 406. For example, at least a portion of the top surface of the rubber cover 404 may contact at least a portion of the bottom surface of the metal mesh 406. In another example, the entire top surface of the rubber cover 404 may contact the metal mesh 406. However, when the waterproof mesh 402 is not implemented, because of the empty top air cavity 650 between the metal mesh 406 and the ECM device 400, the entire metal mesh 406 does not contact the top surface of the rubber cover 404.

[0040] Figure 9A top / side view of a metal mesh 406 that can be implemented in a wireless microphone 100 according to various embodiments is shown. The metal mesh 406 can be made of any metallic material, such as stainless steel, chromium, bronze, etc. In other embodiments, the metal mesh 406 can be made of any hardened material capable of preventing the ingress of debris and other solid particles, such as hard plastic or resin. In some embodiments, the metal mesh 406 is located within an external opening 250 of the housing 200 and is assembled / attached to the housing 200 via ultrasonic welding. In some embodiments, the thickness of the metal mesh 406 varies from 0.1 mm to 0.8 mm, and is preferably 0.2 mm or similar thickness.

[0041] Figure 10 A top / side view of a waterproof mesh 402 that can be implemented in a wireless microphone 100 according to various embodiments is shown. The waterproof mesh 402 protects the ECM device 400 from dust and water / liquids and meets waterproof standards such as IPX-4, IPX-5, IPX-6, and IPX-7. The waterproof mesh 402 can be made of suitable materials such as fabric, plastic, or rubber. In some embodiments, the waterproof mesh 402 is located within an external opening 250 of the housing 200 and is assembled / attached to the housing 200 via an adhesive (such as glue or tape). In some embodiments, the thickness of the waterproof mesh 402 varies from 0.1 mm to 0.8 mm, and is preferably 0.3 mm or similar thickness.

[0042] Figure 11A A top / side view of a rubber cover 404 that can be implemented in a wireless microphone 100 according to various embodiments is shown. Figure 11BA bottom / side view of a rubber cover 404 that can be implemented in a wireless microphone 100 according to various embodiments is shown. Generally, if the ECM device 400 is mounted directly on a mechanical structure, such as the housing 200 and / or the inner housing 430, shock / vibration and sound / audio coupling will exist between the ECM device 400 and the mechanical structure, resulting in a significant degradation of the audio performance of the ECM device 400. In some embodiments, the rubber cover 404 includes a seal / sleeve that at least partially encloses the ECM device 400, thereby isolating (decoupling) the ECM device 400 from the housing 200 and the inner housing 430, and thus protecting the ECM device 400 from shock / vibration and sound / audio interference from the housing 200 and the inner housing 430. As shown, the rubber cover 404 only partially encloses the top surface of the ECM device 400 to allow the ECM device 400 to properly capture audio sounds from the environment. The rubber cover 404 can be made of any rubber material, such as silicone rubber. In other embodiments, the rubber cap 404 is made of any suitable material that provides isolation for the ECM device 400. In some embodiments, the rubber cap 404 (alongside the ECM device 400) is located within an inner opening 440 of the inner housing 430. The thickness of the rubber cap 404 can range from 0.3 mm to 1.0 mm, and is preferably 0.5 mm or similar.

[0043] Figure 12 This is a flowchart of the method steps for constructing a wireless microphone 100 according to various implementation schemes. Although including Figures 1 to 1 The system described in 1 describes the method steps, but those skilled in the art will understand that any system configured to perform the method steps in any order falls within the scope of various implementations.

[0044] Method 1200 begins by obtaining (at step 1210) the outer housing 200 and inner housing 430 of the wireless microphone 100. As... Figures 2 to 4 As shown, the outer casing 200 includes, but is not limited to, a front side 210 and a rear side 260. When the front side 210 and the rear side 260 of the outer casing 200 are assembled together, the front and rear sides form an external opening 250 in the top side 220 of the outer casing 200. Figures 4 to 5 As shown, the inner housing 430 is configured to include an inner opening 440, which is located directly below the outer opening 250 of the outer housing 200. Figures 4 to 8 As shown, the combination of the outer opening 250 of the outer shell 200 and the inner opening 440 of the inner shell 430 defines / forms an integral cavity 600 including a top air cavity 650. Figures 4 to 8As shown, the physical dimensions of the outer shell 200 (with an external opening 250) and the inner shell 430 (with an internal opening 440) can affect the height of the top air cavity 650. In some embodiments, the outer shell 200 and the inner shell 430 are configured with appropriate physical dimensions to form a “shallow” top air cavity 650 as described in the embodiments herein. In these embodiments, the outer shell 200 and the inner shell 430 are configured with specific height dimensions such that the external opening 250 is positioned relative to the inner opening 440 to create / form a shallow top air cavity 650, as described in the embodiments herein. For example, the outer shell 200 and the inner shell 430 are configured such that a shallow top air cavity 650 having the dimensions and / or size ratios described in the embodiments herein is formed / created.

[0045] Method 1200 also obtains (at step 1220) various other remaining components of the wireless microphone 100. For example... Figures 2 to 4 As shown, other remaining components of the wireless microphone 100 include a power button 240, clip 270, wireless communication module 410, power supply 420, ECM device 400, rubber cover 404, waterproof mesh 402, and metal mesh 406. Method 1200 assembles (at step 1230) the various main components of the wireless microphone 100 (including the power button 240, clip 270, wireless communication module 410, and power supply 420). The various main components of the wireless microphone 100 can be arranged according to... Figures 2 to 4 Assemble as shown.

[0046] Method 1200 then positions / attaches (at step 1240) the ECM device 400 and the rubber cover 404 within the inner opening 440 of the inner housing 430. For example... Figures 4 to 8 As shown, the ECM device 400 can be inserted into the rubber cover 404, and then the ECM device 400 with the rubber cover 404 can be placed into the inner opening 440 of the inner housing 430. Method 1200 positions / attaches (at step 1250) the waterproof mesh 402 within the outer opening 250 of the outer housing 200, as... Figures 4 to 8 As shown. The waterproof mesh 402 can be attached to the housing 200 via an adhesive (such as glue or tape). Method 1200 positions / attaches (at step 1260) the metal mesh 406 within the external opening 250 of the housing 200, as shown. Figures 4 to 8 As shown. The metal mesh 406 can be positioned on top of the waterproof mesh 402 and flush with the housing 200, surrounding the outer opening 250 of the housing 200. The metal mesh 406 can be attached to the waterproof mesh 402, or there can be a small gap between the metal mesh 406 and the waterproof mesh 402. For example, the metal mesh 406 can be assembled to the housing 200 via ultrasonic welding.

[0047] In the aforementioned technique used to construct the wireless microphone 100, a "shallow" top air cavity 650 can be formed between the top surface of the ECM device 400 and the external opening 250 of the housing 200. For example... Figures 6 to 8 As shown, the height of the top air cavity 650 (measured along vertical line 610) can be a fraction of the width of the top air cavity 650 (the widest part of the top air cavity 650). In some embodiments, the ratio of the height to the width of the top air cavity 650 is in the range of 1 / 6 to 1 / 2. Also as... Figures 6 to 8 As shown, the height of the top air cavity 650 can be a fraction of the width of the ECM device 400 (the widest part of the ECM device 400). In some embodiments, the ratio of the height of the top air cavity 650 to the width of the ECM device 400 is in the range of 1 / 6 to 1 / 2. Figures 2 to 8 As shown, the height of the top air cavity 650 can be the height of the outer shell 200 (e.g., Figures 2 to 3 (as indicated by "H" in the figure). In some embodiments, the ratio of the height of the top air cavity 650 to the height of the housing 200 is in the range of 1 / 20 to 1 / 10.

[0048] Furthermore, in Figure 8 In an alternative embodiment, components of the wireless microphone 100 are positioned such that at least a portion of the rubber cover 404 contacts at least a portion of the waterproof mesh 402. In another embodiment, where the waterproof mesh 402 is not implemented, components of the wireless microphone 100 are positioned such that at least a portion of the rubber cover 404 contacts at least a portion of the metal mesh 406. The shallower top air cavity 650 provided by the disclosed technology offers better frequency response performance (flatter frequency response) in terms of the audio sound captured by the ECM device 400 and the audio data transmitted to the receiver 150 of the wireless microphone system 101 compared to the deeper top air cavity commonly found in conventional wireless microphones.

[0049] In summary, the mechanical design techniques used to construct the wireless microphone 100 include an outer housing 200 with an external opening 250, an inner housing 430 with an internal opening 440, an ECM device 400, a rubber cover 404, a waterproof mesh 402, and a metal mesh 406. The rubber cover 404 partially encloses the ECM device 400 to provide shock and vibration protection. The ECM device 400 with the rubber cover 404 is positioned within the internal opening 440 of the inner housing 430. The waterproof mesh 402 and the metal mesh 406 are located above the ECM device 400 and within the external opening 250 of the outer housing 200. The waterproof mesh 402 protects the ECM device 400 from dust and water / liquids, and the metal mesh 406 protects the ECM device 400 from debris and other solid particles. The combination of the metal mesh 406 and the waterproof mesh 402 provides wind protection for the ECM device 400.

[0050] The combination of the external opening 250 of the housing 200 and the internal opening 440 of the inner and outer housings 430 defines an integral cavity 600 within the wireless microphone 100. The integral cavity 600 includes, but is not limited to, a top air cavity 650 and contains various components of the wireless microphone 100. An ECM device 400, a rubber cover 404, a waterproof mesh 402, and a metal mesh 406 are assembled within the integral cavity 600. The top air cavity 650 within the integral cavity 600 includes the empty space between the ECM device 400 and the external opening 250 of the housing 200. Because the waterproof mesh 402 and the metal mesh 406 provide various forms of protection, the top air cavity 650 above the ECM device 400 can be shallower than top air cavities seen in conventional wireless microphones. The height of the top air cavity 650 extends from the top surface of the ECM device 400 toward the external opening 250 of the housing 200. The height of the top air cavity 650 in the exemplary wireless microphone 100 can be a fraction of the width of the top air cavity 650. Additionally, the height of the top air cavity 650 in the exemplary wireless microphone 100 may be a fraction of the width of the ECM device 400.

[0051] At least one technical advantage of the disclosed technology compared to existing technologies lies in the implementation and construction of a mechanical design for the wireless microphone, which allows for a shallower air cavity above (top) the ECM device compared to conventional wireless microphones. The "shallow" top air cavity provided by the disclosed technology offers better frequency response performance in terms of both the audio sound captured by the ECM device and the audio data transmitted to the receiver of the wireless microphone system compared to the deep top air cavities commonly found in conventional wireless microphones. Other technical advantages of the disclosed technology compared to existing technologies include the ability of the wireless microphone to protect the ECM device from debris, dust, moisture, shock, and vibration. These technical advantages provide one or more technological improvements over existing methods.
