Example Embodiment

[0031] Embodiment one

[0032] figure 1 A cross-sectional view of an embodiment of a sound pickup device provided by the present invention.

[0033] refer to figure 1 As shown, the sound pickup device provided in this embodiment can be applied to electronic devices such as earphones, and specifically includes a housing 10 and a microphone 20 , and a hollow channel 100 is also provided inside the housing.

[0034] The microphone 20 is disposed inside the housing 10 , and the hollow channel 100 is also located inside the housing 10 , and its length is longer than the thickness of the housing 10 . One end of the hollow channel 100 is opened on the shell, and the other end extends to the microphone 20, so that the sound needs to pass through the long hollow channel 100 when it reaches the microphone 20 through the shell 10. When a sound reaches the microphone 20, the microphone 20, the sound can be converted into a corresponding electrical signal to complete sound pickup.

Example Embodiment

[0037] Embodiment two

[0038] figure 2 It is a sectional view of another sound pickup device embodiment provided by the present invention.

[0039] refer to figure 2 As shown, the sound pickup device provided by this embodiment is applied to a headset, and specifically includes a shell, which includes a first shell 11 and a second shell 12, and between the first shell 11 and the second shell 12 is also A middle case 30 , a cover member 50 , an electronic circuit board 40 and a microphone 20 are provided.

[0040] When the sound pickup device is placed flat on a plane, the first housing 11 is located at the uppermost side, while the second housing 12 is located at the lowermost side, and the two housings form a closed cavity for the middle housing The body 30, the cover member 50, the electronic circuit board 40 and the microphone 20 are enclosed inside.

[0041] The middle housing 30 acts as a support, one side of which faces the first housing 11 and the other side face...

Example Embodiment

[0048] Embodiment three

[0049] Figure 5 A cross-sectional view of another sound pickup device embodiment provided for the invention.

[0050] refer to Figure 5 As shown, the sound pickup device provided in this embodiment is based on the previous embodiment with additional damping cloth 70 and silicone sleeve 80 .

[0051] The damping cloth 70 covers the surface of the microphone 20 to make the sound softer and more beautiful, and it can also play a dust-proof role to prevent dust from entering the interior of the microphone 20 through the hollow channel 100 .

[0052] The silicone sleeve 80 is used to wrap around the microphone 20 so that the microphone 20 can be tightly socketed in the through hole of the middle housing 30 to avoid vibration.

Abstract

The invention provides sound pickup equipment and a headset. The sound pickup equipment comprises a shell, a microphone and a long hollow channel. The microphone is connected to an external portion of the shell through the hollow channel. After entering into the shell, a sound reaches the microphone through the long hollow channel. The sound needs a long spreading route. During a spreading process, sound pressure can become stable because of the long hollow channel so that a microphone spray phenomenon generated because of irregular sound pressure can be avoided and a user can get a good usage experience.

Description

technical field [0001] The invention relates to the technical field of acoustics, in particular to a sound pickup device and an earphone. Background technique [0002] With the rapid development of electronic technology, headsets have become a standard configuration of many mobile devices, through which users can perform entertainment or communicate with other users. After solving the problem of whether the headset can make a call at the beginning, people pay more and more attention to the pursuit of high-quality call effects. Among them, the performance of the sound pickup device on the headset plays a vital role in obtaining high-quality sound , the sound pickup device consists of a microphone shell and electronic components wrapped in the microphone shell. The inventor found that when the user uses the headset to talk or sing, the sound pickup device sometimes produces a spray mark phenomenon, that is, the sound obtained by the sound pickup device after restoration produ...
