The utility model provides an earphone for receiving electric signals sent by a media player or a receiver and converting the electric signals into audible sound waves by using a loudspeaker close to an ear.

In an embodiment of the present invention, as shown in fig. 1 to 4, the headset includes: the sound pickup device comprises a shell 10, wherein the shell 10 is provided with an accommodating cavity 11 and a sound pickup hole 12 communicated with the accommodating cavity 11; the slow flow member 20 is arranged in the accommodating cavity 11, the slow flow member 20 is provided with an air inlet 21, an air outlet 22 and a slow flow channel 23 for communicating the air inlet 21 with the air outlet 22, and the air inlet 21 is communicated with the sound pickup hole 12; the sound filtering layer 30 is installed at one or more positions of the air inlet 21, the air outlet 22 and the slow flow channel 23; and the microphone 40 is arranged in the accommodating cavity 11 and is opposite to the air outlet 22.

The specific shape of the housing 10 is not limited, and only the housing having the accommodating cavity 11 is required; for example, the housing 10 may be formed by splicing a front case and a rear case. The headset further includes a speaker and a microphone 40 disposed in the accommodating chamber 11, the speaker being configured to output an audio source, and the microphone 40 being configured to receive the audio source so that the audio source can be converted into an electrical signal, thereby enabling a user to perform a voice call through the headset. The sound pickup hole 12 is used for sound waves to enter the accommodating cavity 11, and external air flow enters the accommodating cavity 11 along with the sound waves. The flow slowing member 20 may be cylindrical or spherical, and is not limited specifically, and only needs to have a flow slowing channel 23, an air inlet 21 and an air outlet 22. The air inlet 21 and the sound pickup hole 12 may be directly connected in a butt joint manner or indirectly connected, and are not limited herein. The slow flow channel 23 may be a straight channel or a curved channel, and is not limited herein. After the sound waves and the airflow enter the sound pickup hole 12, the sound waves and the airflow pass through the slow flow channel 23 and then flow to the microphone 40. The slow flow channel 23 can slow down the flow velocity of the airflow or reduce the flow rate of the airflow, so as to reduce the flow velocity of the airflow blowing to the microphone 40 and reduce the influence of the airflow on the sound-collecting effect of the microphone 40.

The sound filtering layer 30 is used for filtering and absorbing wind noise generated by airflow in the accommodating cavity 11, the material of the sound filtering layer 30 can be a cotton layer or a net layer, and the sound filtering layer is not limited in particular and only can satisfy the requirement that sound waves can penetrate through the sound filtering layer and can absorb the wind noise generated by the airflow. The sound filtering layer 30 may be disposed at one of the air inlet 21, the air outlet 22 and the slow flow passage 23, or disposed at both the air inlet 21 and the air outlet 22. For example, the sound filter layer 30 includes a first sound filter layer 30 and a second sound filter layer 30, the first sound filter layer 30 is disposed at the air inlet 21, and the second sound filter layer 30 is disposed at the air outlet 22, so that the air flow can be effectively reduced in noise when flowing into and out of the slow flow passage 23. The sound filtering layer 30 and the slow flow member 20 may be mounted by bonding or by positioning and clamping, and are not limited herein.

The microphone 40 may be directly opposite the outlet 22, or may be spaced apart from the outlet. For example, the earphone further includes a circuit board mounted in the accommodating cavity 11, the circuit board is provided with a sound passing hole, and the microphone 40 and the current buffering element 20 are mounted on two opposite sides of the circuit board corresponding to the sound passing hole, so as to provide a supporting base for the microphone 40 and the current buffering element 20, and to achieve electrical connection between the circuit board and the microphone 40. The air outlet end of the current buffering member 20 can be covered on the sound passing hole, so that the microphone 40 can only receive sound waves from the sound pickup hole 12, and the influence of noise in the accommodating cavity 11 is avoided. Of course, the earphone may further include a sealing sleeve covering the microphone 40 to further block the microphone 40 and the internal noise of the accommodating cavity 11, so as to improve the sound receiving effect.

According to the earphone, the slow flow piece 20 is arranged between the microphone 40 and the sound pick-up hole 12, the sound filtering layer 30 is arranged at the air inlet 21 and/or the air outlet 22 of the slow flow piece 20, so that air flow needs to flow through the slow flow channel 23 and the sound filtering layer 30 firstly and then flows to the microphone 40, the slow flow channel 23 can slow down the flow rate of the air flow or reduce the flow rate of the air flow, and the sound filtering layer 30 can absorb and filter noise formed by the air flow and allow sound waves of a user to pass through, so that the flow rate and the flow rate of the air flow flowing to the microphone 40 can be reduced, noise formed by the air flow in the accommodating cavity 11 can be reduced, wind noise can be reduced, the sound receiving effect of the earphone is improved, and user experience is improved.

In an embodiment, as shown in fig. 2, an air inlet end of the slow flow member 20 is formed with a first sinking groove 24, the air inlet 21 is opened in the first sinking groove 24, and the sound filtering layer 30 is installed in the first sinking groove 24; and/or a second sinking groove 25 is formed at the air outlet end of the slow flow member 20, the air outlet 22 is opened in the second sinking groove 25, and the sound filtering layer 30 is installed in the second sinking groove 25. It should be understood that the three schemes included in "and/or" in the present embodiment respectively correspond to the three schemes included in "the air inlet 21 and/or the air outlet 22" in the above embodiments. The installation of the sound filtering layer 30 at the air inlet 21 and the air outlet 22 is realized through the first sinking groove 24 and the second sinking groove 25, which not only can reduce the installation difficulty of the sound filtering layer 30, but also can improve the installation stability of the sound filtering layer 30.

Specifically, as shown in fig. 1 and 2, the earphone further includes a sound filtering sleeve 50 sleeved on the slow flow member 20. The sound-filtering cover 50 is used to filter and absorb the noise outside the buffer 20, and the material of the sound-filtering cover may be the same as that of the sound-filtering layer 30. When the airflow passes through the sound-filtering layer 30, a portion of the airflow turns to flow through the outer wall of the slow flow element 20, and the sound-filtering sleeve 50 can effectively reduce wind noise generated by the portion of the airflow, so as to further improve the sound-receiving effect of the microphone 40. The peripheral wall of the slow flow member 20 may be provided with a positioning boss, and the end of the sound filtering sleeve 50 abuts against the positioning boss to realize positioning and installation. The positioning boss can extend along the circumferential direction of the flow slowing piece 20 so as to increase the abutting area with the sound filtering sleeve 50 and improve the installation stability of the sound filtering sleeve 50.

In practical application, as shown in fig. 1 to 4, the housing 10 is further provided with a pressure relief hole 13, and the pressure relief hole 13 penetrates through a hole wall of the sound pickup hole 12. When the airflow flows into the sound pickup hole 12, a part of the airflow flows from the pressure relief hole 13 to the outside air, so as to primarily slow down the flow rate and velocity of the airflow flowing to the microphone 40, and further reduce the wind noise generated by the airflow.

In an embodiment, as shown in fig. 5 to 12, a flow slowing structure is disposed in the flow slowing channel 23 for dispersing or slowing the airflow flowing to the air outlet 22. The slow flow structure may be a protruding structure or a slotted hole structure, and the flow rate or the flow rate of the air flowing through the slow flow channel 23 is only required to be reduced without limitation. For example, the slow flow structure may include a bent section of the slow flow channel 23, and by setting the slow flow channel 23 as a bent section, the flow speed of the air flow can be reduced during the turning process, so as to effectively reduce the flow speed of the air flow flowing through the microphone 40.

In an embodiment, as shown in fig. 5 and 6, the flow slowing structure includes a drain hole 231 opened in the flow slowing member 20, and the drain hole 231 communicates the flow slowing channel 23 with the accommodating cavity 11. The air flow passing through the slow flow channel 23 partially flows out of the drain hole 231 to reduce the amount of air flow to the microphone 40, thereby effectively reducing wind noise. The number of the drain holes 231 may be plural, and the plurality of drain holes 231 are spaced along the circumferential direction of the slow flow channel 23 to increase the drain amount of the air flow, and further reduce the amount of the air flow flowing to the microphone 40. In combination with the above-mentioned embodiment of the sound-filtering sleeve 50, the airflow flowing out of the drainage hole 231 will flow through the sound-filtering sleeve 50, so that the wind noise generated when the airflow flows through the drainage hole 231 can be absorbed and filtered by the sound-filtering sleeve 50, so as to reduce the influence on the sound-collecting effect of the microphone 40. Specifically, the housing 10 may further be provided with a drainage port communicating with the accommodating cavity 11, so that the air flowing out of the drainage channel 23 can flow to the outside air through the drainage hole 231, thereby preventing the air from generating air pressure in the accommodating cavity 11.

In an embodiment, as shown in fig. 7 and 8, the slow flow channel 23 includes an inflow section 232 and an outflow section 233 arranged along an airflow direction, the slow flow structure includes a flow dividing rib 234 arranged on the inflow section 232, and the flow dividing rib 234 divides the inflow section 232 into at least two parallel flow dividing channels 235. The inflow section 232 is adjacent to the inlet 21, and the outflow section 233 is adjacent to the outlet 22. The air flow flowing into the inlet 21 simultaneously flows through the parallel diversion channels 235, so that the air flow flowing through the inlet 21 can be diverted to reduce the flow rate. It should be noted that only the inflow section 232 is divided into the diversion channels 235, and the integrity of the outflow section 233 is maintained, so that the integrity and continuity of the sound wave can be prevented from being damaged, and the sound receiving quality of the earphone can be ensured. Although the air flow is converged again at the outlet section 233, the flow splitting process at the inlet section 232 effectively reduces the total flow rate of the air flow, that is, the converged air flow rate is relatively smaller, so as to effectively reduce the wind noise.

Specifically, as shown in fig. 9 and 10, the shunting rib 234 protrudes from the air inlet 21, so that the air flow can contact the shunting rib 234 to realize shunting before entering the air inlet 21, thereby improving stability and fluency of the air flow in the shunting process, avoiding air flow disturbance in the slow flow channel 23, and further preventing wind noise from being generated. The part of the shunting rib 234 protruding out of the air inlet 21 can be arranged in a tapered shape with a width gradually reduced from the air inlet 21 to the sound pickup hole 12, so that the protruding part of the shunting rib 234 forms a flow guiding inclined plane, and the shunting process of the air flow is smoother and more natural. In practical applications, the protruding portion of the shunting rib 234 can protrude into the sound pickup hole 12, so that the internal structure of the earphone is simpler and more compact, and the volume of the earphone can be reduced.

In an embodiment, as shown in fig. 11 and 12, the slow flow structure includes a slow flow groove 236 opened on the wall of the slow flow channel 23, and the slow flow groove 236 is spirally disposed around the flow channel. The slow flow groove 236 extends spirally along the extending track of the slow flow passage 23, so that the air flowing through the slow flow passage 23 flows along the slow flow groove 236 in a spiral direction, thereby reducing the flow speed of the air during the circulation turning process, and finally effectively weakening the flow speed of the air flowing through the microphone 40. It can be understood that, since the slow flow member 20 still retains the slow flow channel 23 as the main channel, the transmission of sound waves in the slow flow channel 23 is not affected, that is, the sound receiving quality of the earphone can be ensured.

In one embodiment, as shown in fig. 1 to 4, a fixed cylinder 14 is protruded from an inner wall of the housing 10, the fixed cylinder 14 extends along a circumferential direction of the sound pickup hole 12, and the slow flow member 20 is mounted on the fixed cylinder 14. The slow flow member 20 is fixedly matched with the fixed cylinder 14 to realize the stable butt joint of the slow flow member 20 and the sound pick-up hole 12. The one end protrusion in fixed section of thick bamboo 14 that class piece 20 kept away from sound pick-up hole 12, and the periphery wall protrusion end of class piece 20 is equipped with spacing boss, but spacing boss butt in the tip of fixed section of thick bamboo 14 to the installation depth of restriction class piece 20 at fixed section of thick bamboo 14 avoids class piece 20 to be excessively extruded, thereby plays the guard action to class piece 20.

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
