When the user wears the bone conduction earphone, the rear hanger 300 is wound on the back of the brain, and the two ear hangers 200 are respectively hung on the left ear and the right ear, so that the two bone conduction speakers 100 are respectively arranged at the preset positions around the ears of the user and are in contact with the user.
Further description is made below on the structure of the bone conduction speaker, and it is noted that at least one of the two bone conduction speakers in the bone conduction headset has the following structure.
Referring to fig. 2 to 5, the speaker of the bone conduction earphone includes a housing 10, a microphone mechanism, a driving mechanism 30 and a bracket 50.
Wherein, the housing 10 defines an accommodating space, and a first microphone hole 11 and a second microphone hole 12 communicated with the accommodating space; the microphone mechanism is accommodated in the accommodating space and includes a first microphone element and a second microphone element corresponding to the first microphone hole 11 and the second microphone hole 12, respectively, wherein the first microphone element and the second microphone element are used for receiving sound signals input from the first microphone hole 11 and the second microphone hole 12, respectively.
Further, the first microphone hole 11 and the second microphone hole 12 may be cylindrical holes penetrating through the housing, and a central axis of the first microphone hole 11 and a central axis of the second microphone hole 12 respectively have a positive direction pointing from the accommodating space to the outside of the housing 10.
It is noted that the positive direction of the central axis of the first microphone hole 11 and the second microphone hole 12 is directed outside the pinna region of the user when the user wears the bone conduction speaker.
Due to the physiological structure of the auricle, the sound is easily gathered at the auricle, so that the sound gathering phenomenon occurs, if the positive direction of the central axis of the first microphone hole 11 or the second microphone hole 12 is directed to the auricle area of the user, the sound gathered through the auricle is easily received by the corresponding microphone element through the corresponding microphone hole, so that the phenomenon of volume imbalance is caused, especially, when the microphone element corresponding to the microphone hole facing the auricle is the microphone element for collecting the background sound, the volume of the sound collected by the microphone element is larger than that of the sound collected by the other microphone element for collecting the human sound, so that the sound quality of the bone conduction speaker is influenced.
In the above manner of the present application, the bone conduction speaker is configured such that the positive direction of the central axis of the first microphone hole 11 and the second microphone hole 12 is directed to the outside of the auricle area of the user, so as to reduce the occurrence of the situation that the sound collected by the auricle enters the corresponding microphone element through the microphone hole, thereby improving the sound quality of the bone conduction speaker to a certain extent.
Specifically, the housing 10 includes a contact wall 13 that is in contact with the skin of a human face when worn by a user, an outer side wall 14 that is disposed opposite the contact wall 13, and a peripheral side wall 15 that connects the outer side wall 14 at one end and extends toward the skin of the human face to connect the contact wall 13 at the other end. Wherein the first microphone aperture 11 is located in the outer side wall 14 and the second microphone aperture 12 is located in the peripheral side wall 15.

Further, referring to fig. 3, when the microphone device is worn by a user, the first microphone hole 11 forms a first connection line m between a center point of a contour formed on the outer surface of the housing 10 and a corner of the mouth of the user, the second microphone hole 12 forms a second connection line n between the center point of the contour formed on the outer surface of the housing 10 and the corner of the mouth of the user, and an included angle θ between the first connection line m and the second connection line n is smaller than 30 °, so that an extension line of the connection line of the first microphone hole 11 and the second microphone hole 12 is located in a region near the mouth of the user.
In one application scenario, the first microphone hole 11 and the second microphone hole 12 are in line with the user's mouth when the bone conduction speaker is worn by the user.
Further, an included angle between the positive direction of the central axis of the first microphone hole 11 and the positive direction of the central axis of the second microphone hole 12 is not less than 70 degrees, so that the correlation of the sound collected by the microphone elements corresponding to the first microphone hole and the second microphone hole is reduced, and the noise reduction effect is improved.
In an application scenario, an included angle between a positive direction of a central axis of the first microphone hole 11 and a positive direction of a central axis of the second microphone hole 12 is 90 °, at this time, a correlation between sounds collected by the first microphone element and the second microphone element through the first microphone hole 11 and the second microphone hole respectively is minimum, and a noise reduction effect is optimal.
