Description

Technical Field

[0001] This utility model relates to a sound receiving device, and more particularly to a microphone head device for a headset microphone. Background 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 coil to the microphone head, it can impair the microphone's recording capabilities. Mild cases may result in noisy or distorted sound when played back by broadcasting equipment; severe cases may damage the microphone head due to prolonged exposure to sweat. Therefore, providing a microphone head that mitigates or eliminates the effects of sweat is a topic that requires further research and discussion. Utility Model Content

[0020] See Figure 1 , 2 3. The embodiment of the microphone head device of this utility model is applicable to the wearable unit 92 of a headset microphone 91. The wearable unit 92 includes an ear hook assembly 921, a neck hook assembly 922 and a snake tube 923, suitable for wearing by a user 93 and providing support for this embodiment, a wire assembly 924 for electrically connecting to this embodiment, and a protective sleeve 925 that is fitted outside this embodiment. The wire assembly 924 is disposed on the neck hook assembly 922 and disposed in the snake tube 923.

[0021] See Figure 2 , 3 4. This embodiment includes a microphone head 1 and a microphone head cover 2 that are sleeved together, a waterproof sleeve 3 and a microphone head 4 disposed in the microphone head 1 and the microphone head cover 2, elastic washers 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.

[0022] 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 arranged at angular intervals on the seat body portion 13.

[0023] The front seat portion 11 extends forward integrally from the seat body portion 13 and is annular 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 annular in shape, and the width of the seat body portion 13 in the radial direction is greater than the width of the front seat portion 11 in the radial direction.

[0024] Each of the aforementioned protrusions 14 is generally square-shaped and extends rearward integrally from the seat portion 13. In this embodiment, the microphone head 1 includes two protrusions 14, thus the protrusions 14 are 180 degrees apart from each other. In other embodiments of this utility model, the microphone head 1 may also include only one protrusion 14, or contain three or more of the aforementioned protrusions 14. For example, when the microphone head 1 includes four of the aforementioned protrusions 14, the protrusions 14 may be arranged at 90-degree angular intervals from each other.

[0025] The head cover 2 and the head base 1 cooperate to define an internal space S1. The head cover 2 includes a rear cover 21 that is fitted 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.

[0026] The front end of the front cover 22 has a through-hole 221 that communicates with the internal space S1. The outer surface 222 of the front cover 22 includes a recessed surface 223 located behind the through-hole 221. The recessed surface 223 extends in an arc shape and is continuously curved in the front-rear direction. The recessed surface 223 is located in front of the front seat portion 11 of the microphone head 1 in the front-rear direction. The recessed surface 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.

[0027] 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 seat 1.

[0028] The rear end of the front sleeve portion 31 abuts against the front end of the front seat portion 11 of the mouthpiece 1, and is located in front of the annular gap between the mouthpiece 1 and the mouthpiece cover 2. The width of the front sleeve portion 31 in the radial direction is greater than the width of the rear sleeve portion 32 in the radial direction.

[0029] 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.

[0030] 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 microphone 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.

[0031] The elastic washer 5 is designed to be fitted over the snake tube 923. The elastic washer 5 can initially prevent sweat from flowing along the snake tube 923 to the headstock 1.

[0032] One of the waterproof and breathable membranes 6 is in the shape of a disc and is adhered to the front cover 22 of the microphone head cover 2, covering the front side of the microphone head cover 221. 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 microphone head 221.

[0033] See Figure 3 , 4 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 a certain amount of sweat accumulates in the recessed annular groove 224, it drips directly from the groove. 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.

[0034] 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.

[0035] See Figure 1 , 3 The third feature of this embodiment is that the microphone head seat 1 is provided with the protrusion 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.

[0036] In summary, the beneficial effects of the microphone device of this utility model are as follows: 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.
