Detailed Description

Fig. 1 is a perspective view of an earphone module with a microphone stand according to an embodiment of the present invention. Fig. 2 is a cross-sectional view of the earphone module of fig. 1 with a microphone arm. Referring to fig. 1 and 2, an earphone module 100 with a microphone stand of the present embodiment includes a housing 110, a speaker unit 120, a microphone stand 130, and a microphone 140. The interior of the housing 110 has a speaker chamber C12, a microphone chamber C14 and a sound outlet chamber C16 which are sequentially communicated. The horn unit 120 is disposed in the horn chamber C12. The microphone boom 130 is disposed within the microphone cavity C14. The microphone 140 is housed in the microphone arm 130.

In the earphone module 100 having the microphone holder of the present embodiment, the microphone 140 is disposed between the speaker unit 120 and the sound outlet chamber C16 by using the microphone holder 130. The speaker unit 120 may block the transmission of the ambient noise to the microphone 130, thereby generating a passive anti-noise effect and improving the sound fidelity. Additionally, the microphone 130 may be inserted deep into the ear canal and in proximity to the tympanic membrane to detect sound waves transmitted within the ear canal. Since the microphone 130 is in close proximity to the eardrum of the user, sound waves generated by vibration of the eardrum caused by the user's speaking can be sensitively detected and collected by the microphone 130, and human bones can well transmit the sound emitted from the user into the ear canal and be collected by the microphone 130.

In addition, when assembling the earphone module 100 with the microphone holder of the present embodiment, the microphone 140 may be first clamped in the microphone holder 130, and then the microphone holder 130 is assembled to the microphone cavity C14 in the casing 110, which provides better assembly convenience. In addition, the remaining cavity space of the microphone cavity C14 in front of the speaker unit 120 can be adjusted by changing the volume of the microphone holder 130, so that the phenomenon that the sound emitted by the speaker unit 120 may be attenuated at high frequencies can be improved.

In this embodiment, the earphone module 100 may further include an ear pad 150 sleeved outside the sound outlet cavity C16 of the casing 110. The ear pad 150 can prevent the transmission of ambient noise from outside the housing 110 to the microphone 140, in addition to improving wearing comfort. In addition, the microphone stand 130 of the present embodiment can, for example, keep a distance G10 between the speaker unit 120 and the microphone 140. By adjusting the distance G10, the attenuation of the sound emitted from the speaker unit 120 at high frequencies is also improved. In addition, the housing 110 of the present embodiment has a blocking wall 112, for example, located between the microphone cavity C14 and the sound outlet cavity C16, for blocking the movement of the microphone stand 130 toward the sound outlet cavity C16. In other words, when the earphone module 100 with the microphone boom of the present embodiment is assembled, as long as the microphone boom 130 abuts against the blocking wall 112, it means that the microphone boom 130 is already assembled to be positioned, and the assembling convenience is better.

Fig. 3 is an exploded view of the earphone module of fig. 1 with a microphone boom. Fig. 4 is a perspective view of the headset module with the microphone arm of fig. 1 with a portion of the assembly removed. Referring to fig. 3 and 4, the microphone arm 130 of the present embodiment maintains a sound outlet channel T10 between the microphone 140 and the casing 110. Therefore, the sound emitted from the speaker unit 120 can be transmitted from the sound outlet passage T10 to the sound outlet chamber C16 to reach the eardrum of the user. In addition, when assembling the earphone module 100 having the microphone holder according to the present embodiment, the microphone 140 may be first clamped in the microphone holder 130, and then the microphone holder 130 may be assembled to the microphone cavity C14 in the casing 110, so that the state shown in fig. 4 may be achieved. Then, the speaker unit 120 is assembled to the speaker chamber C12 in the housing 110, and the ear pad 150 is sleeved outside the sound outlet chamber C16 of the housing 110, so as to form the state shown in fig. 1.

Fig. 5 is a perspective view of the microphone boom of the earphone module with the microphone boom of fig. 1. Referring to fig. 2 and 5, the microphone arm 130 of the present embodiment has a front stop 132, for example. The front bumper 132 is located between the microphone 140 and the sound cavity C16 to block the microphone 140 from moving toward the sound cavity C16. In addition, a cushion pad 160 may be disposed between the microphone 140 and the front block 132, and the cushion pad 160 may also have viscosity to adhere the microphone 140 to the microphone stand 130.

Fig. 6 is a perspective view of the assembled microphone boom and microphone of the earphone module with the microphone boom of fig. 1. Referring to fig. 5 and 6, the microphone arm 130 of the present embodiment has a side wall 134. The sidewall 134 surrounds the microphone 140 and thus may limit lateral movement of the microphone 140. The sound outlet passage T10 is located on the side wall 134, for example.

Fig. 7 is a cross-sectional view of fig. 6. Fig. 8 is another cross-sectional view of fig. 6. Referring to fig. 7 and 8, the microphone arm 130 of the present embodiment has a hook 136, for example. The hook 136 is located between the microphone 140 and the speaker chamber C12 (shown in fig. 2) to block the microphone 140 from moving toward the speaker chamber C12. Therefore, the relative position between the microphone 140 and the speaker unit 120 can be maintained to ensure the optimal sound-collecting effect of the microphone 140, and the optimal resonance cavity of the speaker unit 120 to provide the optimal sound quality. The hook 136 has a slope 136A. When the microphone 140 is assembled to the microphone holder 130, the microphone 140 pushes against the inclined surface 136A to deform the hook 136A to a proper degree so that the microphone 140 can be positioned, and then the hook 136 returns to its original shape to block the microphone 140 from moving toward the speaker chamber C12. In addition, the microphone 140 of the present embodiment has a circuit board 142, for example. The microphone arm 130 has a support portion 138. The supporting portion 138 and the hook 136 clamp the circuit board 142 together.
