Description

microphone head assembly Technical Field

[0001] This invention relates to a sound receiving device, and more particularly to a microphone head device for a headset microphone. Prior Technology

[0002] Headset microphones are convenient to use because they do not require handheld operation, and are often used in various static or dynamic scenarios. Static scenarios include telephone customer service or school teaching, while dynamic scenarios include aerobic exercise instruction.

[0003] In aerobic exercise instruction, users sweat due to continuous activity. If sweat travels along the microphone's tube to the microphone head, it can impair the microphone's recording function. Mild cases may result in noisy or distorted sound when played back by broadcasting equipment; severe cases could damage the microphone head due to prolonged exposure to sweat. Therefore, providing a microphone head design that reduces or eliminates the impact of sweat is a topic that requires further research and discussion. Summary of the Invention

[0004] The purpose of this invention is to improve at least one of the disadvantages of the prior art.

[0005] This novel microphone device includes a microphone base, a microphone cover, and a microphone head. The microphone base includes a front portion. The microphone cover is mounted on the front portion of the microphone base and cooperates with the microphone base to define an internal space. The microphone cover includes a sound-receiving hole located at the front end and communicating through the internal space. An outer surface of the microphone cover includes a recessed portion located behind the sound-receiving hole. The recessed portion defines an inwardly recessed annular groove. The microphone head is disposed within the internal space.

[0006] The advantage of this invention is that the grooved surface defines a concave annular groove that can retain sweat, thereby preventing sweat from moving forward along the outer surface to the sound hole, thus reducing or even eliminating the impact of sweat on the microphone device. Simple Explanation of the Diagram

[0007] Other features and effects of this novel invention will be clearly presented in the embodiments with reference to the drawings, wherein: Figure 1 is a perspective view illustrating an embodiment of the novel microphone head device combined with a wearable unit to form a headset microphone; Figure 2 is an incomplete perspective view illustrating this embodiment; Figure 3 is an incomplete exploded perspective view illustrating this embodiment; Figure 4 is an incomplete and partially sectional view illustrating this embodiment; and Figure 5 is an incomplete side view illustrating how this embodiment works. Implementation

[0008] Referring to Figures 1, 2, and 3, one embodiment of this novel microphone head device is adapted for mounting on a wearable unit 92 of a headset microphone 91. The wearable unit 92 includes an ear hook assembly 921 suitable for a user 93 to wear and providing support for this embodiment, a neck hook assembly 922 and a snake tube 923, a power cable assembly 924 for electrically connecting to this embodiment, and a protective sleeve 925 covering the outside of this embodiment. The power cable assembly 924 is disposed on the neck hook assembly 922 and within the snake tube 923.

[0009] Referring to Figures 2, 3, and 4, this embodiment includes a microphone head 1 and a microphone head cover 2 that are connected together from back to front, a waterproof sleeve 3 and a microphone head 4 disposed in the microphone head 1 and the microphone head cover 2, an elastic washer 5 located at intervals behind the microphone head 1, and several waterproof and breathable membranes 6 disposed at the front end of the microphone head cover 2.

[0010] The headstock 1 includes a front seat portion 11 and a rear seat portion 12 spaced apart from each other, a seat body portion 13 integrally connected between the front seat portion 11 and the rear seat portion 12, and a plurality of protrusions 14 disposed on the seat body portion 13 at angular intervals.

[0011] The front seat portion 11 extends forward integrally from the seat body portion 13 and is circular in shape. The front seat portion 11 is used for inserting the waterproof sleeve 3. The rear seat portion 12 is adapted for inserting the snake tube 923 of the wearable unit 92, so as to facilitate the electrical connection of the wire assembly 924 in the snake tube 923 to this embodiment. The seat body portion 13 is circular in shape, and the radial width of the seat body portion 13 is greater than the radial width of the front seat portion 11.

[0012] Each of the protrusions 14 is generally square-shaped and extends rearward integrally from the base portion 13. In this embodiment, the microphone head 1 includes two such protrusions 14, and therefore the protrusions 14 are 180 degrees apart from each other. In other embodiments of this invention, the microphone head 1 may also include only one of the protrusions 14, or may include three or more of the protrusions 14. For example, when the microphone head 1 includes four of the protrusions 14, the protrusions 14 may be arranged at 90-degree angular intervals from each other.

[0013] The head cover 2 and the head base 1 cooperate to define an internal space S1. The head cover 2 includes a rear cover portion 21 that fits over the front seat portion 11 of the head base 1, and a front cover portion 22 that extends forward integrally from the rear cover portion 21.

[0014] The front end of the front cover 22 forms a sound-receiving hole 221 that extends through the front and rear and connects to the internal space S1. An outer surface 222 of the front cover 22 includes a recessed portion 223 located behind the sound-receiving hole 221. The recessed portion 223 extends in an arc shape and is continuously curved in the front-rear direction. The recessed portion 223 is located in front of the front seat portion 11 of the microphone head 1 in the front-rear direction. The recessed portion 223 defines a concave annular groove 224 that extends radially inward toward the internal space S1. The concave annular groove 224 is located in front of the front seat portion 11.

[0015] The waterproof sleeve 3 is made of silicone and is disposed in the internal space S1, positioned at intervals behind the microphone hole 221. The waterproof sleeve 3 can be adhered and fixed to other components with waterproof adhesive to further improve the waterproof effect. The waterproof sleeve 3 includes a front sleeve portion 31 that fits over the microphone head 4 and a rear sleeve portion 32 that inserts into the front seat portion 11 of the microphone head 1.

[0016] The rear end of the front sleeve 31 abuts against the front end of the front seat 11 of the mouthpiece 1, and is located in front of an annular gap between the mouthpiece 1 and the mouthpiece cover 2. The width of the front sleeve 31 in the radial direction is greater than the width of the rear sleeve 32 in the radial direction.

[0017] The rear sleeve 32 abuts against the inner surface of the front seat 11 of the headstock 1 and is adapted for the insertion of the wire assembly 924, while also assisting in positioning the wire assembly 924.

[0018] The microphone head 4 is disposed in the internal space S1. Specifically, the microphone head 4 is inserted into the front sleeve portion 31 of the waterproof sleeve 3 and is located between the microphone head cover 2's sound receiving hole 221 and the front and rear of the waterproof sleeve 3. The microphone head 4 is suitable for electrical connection with the wire assembly 924, thereby enabling the conversion of sound into an electrical signal that is output from the wire assembly 924.

[0019] The elastic washer 5 is suitable for being fitted onto the coil 923. The elastic washer 5 can initially prevent sweat from flowing along the coil 923 to the headstock 1.

[0020] One of the waterproof and breathable membranes 6 is in the shape of a disc and is adhered to the front cover portion 22 of the microphone head cover 2, covering the front side of the sound receiving hole 221 of the microphone head cover 2. The remaining waterproof and breathable membranes 6 are in the shape of a ring and are adhered between the microphone head 4 and the microphone head cover 2, located behind the sound receiving hole 221.

[0021] Referring to Figures 3, 4, and 5, the first feature of this embodiment is that the microphone cap 2 includes the recessed surface 223 and the recessed annular groove 224. As sweat moves forward along the outer surface 222 of the microphone cap 2 towards the sound receiving hole 221, the sweat is retained in the recessed annular groove 224. After accumulating to a certain amount, the sweat drips directly from the recessed annular groove 224. In this way, sweat is prevented from moving along the outer surface 222 to the sound receiving hole 221, thereby reducing or even eliminating the impact of sweat on this embodiment.

[0022] The second feature of this embodiment is that by using other waterproofing methods, such as setting the waterproof sleeve 3, bonding the waterproof sleeve 3 to other components with waterproof adhesive, setting the waterproof and breathable membrane 6 in front of the microphone head 4, and setting the elastic washer 5 behind the microphone head seat 1, the impact of sweat on this embodiment can be further reduced or eliminated.

[0023] Referring to Figures 1 and 3, the third feature of this embodiment is that the headstock 1 is provided with protrusions 14, which can increase the friction force, thereby making it suitable for positioning the sheath 925 on this embodiment and preventing it from easily detaching from this embodiment.

[0024] In summary, the function of this novel microphone device is that the groove face 223 defines the concave annular groove 224 that can be used to retain sweat, thereby preventing sweat from moving forward along the outer surface 222 to the sound receiving hole 221, thereby reducing or even eliminating the impact of sweat.

[0025] The above description is merely an embodiment of this invention and should not be construed as limiting the scope of the patent application of this invention. Furthermore, any simple equivalent variations and modifications made in accordance with the scope of the patent application and the patent specification of this invention should also be covered by the scope of the patent application of this invention.
