FIG. 2 is an enlarged view of FIG. 1 at A;
FIG. 3 is an exploded view of the present utility model;
Fig. 4 is a perspective view of the present utility model.
The specific embodiment is as follows:
the utility model will be further described with reference to specific examples and figures.
See fig. 1 to 4, which are structures for reducing wind noise of a bluetooth headset, comprising: a casing 1, a cover 2 covering the casing 1 and forming a closed space with the casing, a baffle 3, a sealing gasket 4 and a conversation microphone 5 which are positioned in the closed space, wherein a sound inlet 11 is formed at the lower part of the casing 1, the baffle 3 is fixed in the casing 1 and divides the closed space into a first chamber 21 and a second chamber 22, and the conversation microphone 5 is arranged on the baffle 3 and positioned in the second chamber 22; the sound inlet hole 11 penetrates through the sealing gasket 4 and the partition board 3 and is led into the conversation microphone 5, the sound inlet hole 11 comprises at least one section of first hole type structure 101 which is longitudinally distributed and at least one section of second hole type structure 102 which is transversely distributed, and the first hole type structure 101 is communicated with the second hole type structure 102. The sound inlet 11 further comprises a noise reduction chamber 6 formed between the first hole type structure 101 and the second hole type structure 102 for reducing air flow. The noise reduction chamber 6 is a square chamber. Thus being convenient for slowing down the airflow and effectively reducing wind noise.
In the structural implementation mode, the sound inlet 11 is divided into the hole type structures which are communicated in a plurality of sections, and a certain included angle exists between each two hole type structures, so that the air flow entering the sound inlet 11 is not directly led to the conversation microphone 5 any more, but is led to the conversation microphone 5 after turning, the speed of the air flow can be slowed down by the design, the air flow is prevented from impacting the conversation microphone 5, and the wind noise is effectively reduced. And, the structure is succinct practical, and the production of being convenient for does not set up multilayer sound insulation material between sound inlet 11 to the conversation microphone 5, that is to say, when utilizing the sound inlet 11 of L shape to slow down air current speed, can not influence the propagation of sound, can not weaken the human voice, can guarantee the quality of conversation. Further, the noise reduction chamber 6 is square, and the inner diameter of the noise reduction chamber is larger than that of the first hole type structure 101, so that the air flow entering along the first hole type structure 101 can be gathered or form vortex at corners, and therefore the air flow entering along the first hole type structure 101 is stagnated at the corners, so that the noise reduction chamber can still effectively reduce wind noise and ensure the conversation quality when the noise reduction chamber is used in special scenes such as outdoors, running at high speed or riding in a windy day.
The housing 1 has a boss 12 formed in the first chamber 21. And the first hole pattern 101 is located inside the boss 12. Therefore, in order to reserve space for the noise reduction chamber 6 and the sound inlet hole 11, the sound inlet hole 11 is convenient to be led into the conversation microphone 5, and secondly, the sealing gasket 4 is convenient to be arranged, so that the sealing performance is enhanced.
The lower end face of the cover body 2 is provided with a latch 2A, and the shell 1 is provided with a clamping groove 2B for matching and clamping with the latch 2A. Therefore, in order to better fix, a closed space is formed, and after the latch 2A and the clamping groove 2B are buckled, the sound insulation effect can be enhanced, so that the conversation microphone 5 is not interfered by other noise around the earphone.
The sealing gasket 4 is made of EVA. The partition 3 forces the gasket 4 against the boss 12. The sealing gasket 4 is made of soft EVA material, and the sealing gasket 4 is tightly attached after the partition plate 3 is extruded, so that the phenomenon of sound leakage is prevented.
The second hole pattern 102 is a stepped groove. The stepped reduction step by step can slow down the air flow passing through the noise reduction chamber 6, establishes a final line for the conversation microphone 5, and ensures the stability of the effect of reducing wind noise.
The cross section of the sound inlet 11 is L-shaped, and the included angle between the first hole type structure 101 and the second hole type structure 102 is 80-100 degrees.
In one embodiment, the cross section of the sound inlet 11 is L-shaped, the included angle between the first hole type structure 101 and the second hole type structure 102 is 80-100 °, and the inventor has found through repeated research and verification that the wind noise can be effectively reduced by making the air inlet 11L-shaped. In another embodiment, the first hole pattern 101 and the second hole pattern 102 have an included angle of 45-80 degrees.
In summary, in the structural implementation manner, the sound inlet 11 is divided into the hole type structures communicated in a plurality of sections, and a certain included angle exists between each section of hole type structure, so that the air flow entering the sound inlet 11 is not directly led to the conversation microphone 5 any more, but is led to the conversation microphone 5 after turning, and the design can slow down the speed of the air flow, prevent the air flow from impacting the conversation microphone 5, and effectively reduce the wind noise. And, the structure is succinct practical, and the production of being convenient for does not set up multilayer sound insulation material between sound inlet 11 to the conversation microphone 5, that is to say, when utilizing the sound inlet 11 of L shape to slow down air current speed, can not influence the propagation of sound, can not weaken the human voice, can guarantee the quality of conversation. Furthermore, the noise reduction chamber 6 is square, and the inner diameter of the noise reduction chamber is larger than that of the first hole type structure 101, so that the air flow entering along the first hole type structure 101 can be gathered or form vortex at the corners, and therefore the air flow entering along the first hole type structure 101 is stagnated at the corners, and the noise reduction chamber can still effectively reduce wind noise and ensure the conversation quality when the noise reduction chamber is used in special scenes such as outdoors, running at high speed or riding in a windy day.
