The present invention provides a low wind noise earphone assembly 100.

Referring to fig. 1 and 2, in some embodiments, the low wind noise earphone assembly 100 includes a housing 101, a speaker unit 204, a talking microphone 203, and an electronic control module 201. Referring to fig. 5, the inside of the casing 101 has a mounting cavity 502. The speaker unit 204, the communication microphone 203 and the electronic control module 201 are all installed in the installation cavity 502, and the communication microphone 203 and the speaker unit 204 are all in communication connection with the electronic control module 201. The electronic control module 201 can communicate with external devices (e.g., via bluetooth, via cable, for communication). The external device may be a mobile phone, a computer, or the like, and the external device may transmit the sound to be played to the electronic control module 201, and the electronic control module 201 transmits the sound to be played to the speaker unit 204, and the speaker unit 204 plays the sound to be played. The talking microphone 203 faces the first acoustic opening 105, and the talking microphone 203 is used for collecting the talking sound of the user; after the conversation microphone 203 converts the collected sound into an electrical signal, the electrical signal can be transmitted to an external device through the electronic control module 201, so that the conversation function of the low-wind-noise earphone assembly 100 is realized.

Referring to fig. 1, a housing 101 includes a base 102 and a projection 103 connected to each other. The outer surface of the base 102 is provided with an opening surface 104, the opening surface 104 is connected to the outer edge of the base 102, the opening surface 104 is provided with a first sound-absorbing hole 105, the first sound-absorbing hole 105 is a through hole, the first sound-absorbing hole 105 is communicated with the mounting cavity 502, and the first sound-absorbing hole 105 is adjacent to the outer edge of the protruding part 103. Projection 103 is connected to opening surface 104, and projection 103 projects in a direction away from mounting cavity 502 with respect to opening surface 104. The location of aperture face 104 can be seen in fig. 5, where cross-hatching is filled in aperture face 104 in fig. 5 (cross-hatching is provided for purposes of distinction and illustration only and is not true cross-section here) for ease of illustration of aperture face 104.

Since the protrusion 103 has a certain blocking effect on wind in certain wind directions, the wind speed near the connection between the protrusion 103 and the opening surface 104 is low, and the wind speed near the first sound receiving hole 105 is low, which is beneficial to reducing wind noise. For example, in fig. 1, the first acoustic opening 105 is located at the front lower part of the protrusion 103, and if wind blows from the rear or from the upper part, the wind speed of the wind flowing through the vicinity of the first acoustic opening 105 is small by the blocking action of the protrusion 103. The low-wind-noise earphone assembly 100 can reduce wind noise, the structure of the shell 101 is simple, the low-wind-noise earphone assembly 100 does not need to be provided with a complex wind shield, and a pore passage of a microphone hole does not need to be arranged in a complex shape, so that the cost of the low-wind-noise earphone assembly 100 is reduced.

Referring to fig. 1 and 2, in some embodiments, the low wind noise earphone assembly 100 further comprises a first noise reduction microphone 202, and the opening surface 104 further defines a second acoustic opening 106, wherein the second acoustic opening 106 is adjacent to an outer edge of the protrusion 103. The first noise reducing microphone 202 is for collecting ambient noise, the first noise reducing microphone 202 being mounted in the mounting cavity 502 with the first noise reducing microphone 202 facing the second acoustic opening 106. The first noise reduction microphone 202 is also in communication connection with the electronic control module 201, and the electronic control module 201 can reduce noise of the sound to be played according to the sound collected by the first noise reduction microphone 202. The noise reduction function of the first noise reduction microphone 202 is feed-forward noise reduction, and the electronic control module 201 analyzes the ambient noise to generate a sound wave for canceling the ambient noise, and the sound wave is superimposed on the sound to be played and then played from the speaker unit 204. The second sound receiving hole 106 is designed to be similar to the first sound receiving hole 105, and based on the wind shielding effect of the protrusion 103, the wind speed near the second sound receiving hole 106 is low, which is beneficial to reducing the wind noise in the sound collected by the first noise reduction microphone 202, so that the noise collected by the first noise reduction microphone 202 is prevented from being too high, and the noise needing to be processed by the electronic control module 201 is prevented from exceeding the capacity range of the electronic control module 201.

In some embodiments, the low-noise earphone assembly 100 further comprises a second noise-reducing microphone 301 in addition to the first noise-reducing microphone 202, the second noise-reducing microphone 301 being mounted in the mounting cavity 502, the second noise-reducing microphone 301 being in communication with the electronic control module 201. The second noise reduction microphone 301 is used for collecting the sound emitted by the speaker unit 204, and the electronic control module 201 can reduce the noise of the sound to be played according to the sound signal collected by the second noise reduction microphone 301. The noise reduction function of the second noise reduction microphone 301 is feedback noise reduction, the electronic control module 201 analyzes a noise signal to be eliminated according to the sound of the speaker unit 204 collected by the second noise reduction microphone 301, and then generates a sound wave which is cancelled by the noise signal, and the sound wave is superposed on the sound to be played and then played from the speaker unit 204. In this arrangement, noise reduction of the low-wind-noise headphone assembly 100 includes feedforward noise reduction and feedback noise reduction, and the noise reduction effect is better. Referring to fig. 3, the second noise reducing microphone 301 may be mounted adjacent to the first noise reducing microphone 202. Referring to fig. 4, the second noise reduction microphone 301 may also be mounted near the speaker unit 204 (e.g., the second noise reduction microphone 301 is located on the sound emitting side of the speaker unit 204) so as to capture the sound emitted from the speaker unit 204.

This arrangement of the second acoustic opening 106 is to avoid the head bridge (not specifically shown) of the headphone from being blocked, and to avoid affecting the feed-forward noise reduction effect. Specifically, the top of the base portion 102 has a receiving groove 108, the receiving groove 108 is used for receiving a part of the head beam, and the second sound receiving hole 106 is disposed at the rear lower position of the base portion 102, so that the second sound receiving hole 106 is not blocked by the head beam, which can ensure that the first noise reduction microphone 202 smoothly collects the ambient noise, and ensure the noise reduction effect of the first noise reduction microphone 202. In addition, in practice, the first noise reduction microphone 202 inevitably collects the speaking voice of the user, and the second acoustic opening 106 is disposed at the lower rear position of the base 102, so that the second acoustic opening 106 is relatively far away from the mouth of the user, which can reduce the volume of the speaking voice of the user in the voice collected by the first noise reduction microphone 202, facilitate the electronic control module 201 to accurately analyze the environmental noise, and ensure the feedforward noise reduction effect.
