DETAILED DESCRIPTION

[0022] The utility model object of the utility model is further described in detail below in conjunction with the drawings and specific embodiments. The embodiments cannot be described one by one here, but the implementation method of the utility model is not limited to the following embodiments.

[0023] like Figure 1 and 2 As shown, a Bluetooth headset includes a rear cover 7, a front cover 8, an ear shell 9, an ear cap 10, and an integrated structure of a microphone air duct and an indicator light display. The rear cover 7 is connected to the front cover 8, the front cover 8 is connected to one end of the ear shell 9, and the ear cap 10 is installed at the other end of the ear shell 9. The front cover 8 and the rear cover 7 form an inner cavity of the Bluetooth headset, and the integrated structure of the microphone air duct and the indicator light display is installed in the inner cavity of the Bluetooth headset. A sound receiving hole 81 is provided on the front cover 8, and the sound receiving hole 81 is connected to the air duct 51 of the integrated structure of the microphone air duct and the indicator light display. The rear cover 7, the front cover 8, the ear shell 9, and the ear cap 10 belong to the prior art and will not be described in detail.

[0024] like Figure 3 and 4 As shown, the integrated structure of the microphone air duct and indicator light display includes a microphone 1, a control panel 2, an indicator light, a dustproof net 6 and a light-transmitting air duct member 5, and the indicator light includes a first indicator light 3 and a second indicator light 4. A sound transmission hole 21 is provided at the middle position of the front end of the control panel 2, and the microphone 1 is installed on the back of the control panel 2, and the microphone 1 is connected to the left end of the sound transmission hole 21. The light-transmitting air duct member 5 is provided with an air duct 51, one end of the air duct 51 is connected to the right end of the sound transmission hole 21, and the other end of the air duct 51 is covered by a dustproof net 6, and the dustproof net 6 is attached to the outer surface of the light-transmitting air duct member 5. The first indicator light 3 and the second indicator light 4 are symmetrically installed on the front of the control panel 2, located in front of the sound transmission hole 21 of the control panel 2. The first indicator light 3 and the second indicator light 4 are respectively embedded in the light-transmitting air duct member 5. The light-transmitting air duct member 5 is made of transparent material, which is divided into soft glue and hard glue. The soft glue includes TPU (thermoplastic polyurethane rubber), TPE (artificial rubber) or silicone, and the hard glue includes PP (polypropylene), PC (polycarbonate), PVC (polyvinyl chloride), pet (polyethylene terephthalate) or ABS (acrylonitrile-styrene-butadiene copolymer). When the light-transmitting air duct member 5 is made of transparent material of hard glue, it is best to add sealing foam at the connection between the light-transmitting air duct member 5 and the duct to prevent air leakage. The material used for the light-transmitting air duct member in this embodiment is not limited to the material described in this embodiment, and any material with light-transmitting performance can be used.

[0025] Microphone 1 is used to receive sound outside the Bluetooth headset. Control board 2 is a single chip microcomputer, which is used to control electronic components such as indicator lights and microphone 1. The first indicator light 3 and the second indicator light 4 are used to emit light, and the intensity and color of the light are used to indicate the state of the Bluetooth headset. The dustproof net 6 is used to prevent dust outside the Bluetooth headset from entering the Bluetooth headset through the air duct 51. The light-transmitting air duct member 5 is used to scatter the light of the first indicator light 3 and the second indicator light 4, and transmit the sound outside the Bluetooth headset to the microphone 1.

[0026] like Figure 5-8 As shown, the light-transmitting air duct member 5 is provided with an air duct 51, two lamp slots 52 are provided at the front two ends of the sound outlet of the air duct 51, and the sound inlet end of the air duct 51 is arranged at the front end of the light-transmitting air duct member 5. The air duct 51 includes a sound collecting channel 511, a longitudinal sound channel 512, a transverse sound channel 513 and a mainboard positioning groove 514. The outer end of the sound collecting channel 511 is covered by a dustproof net 6, the inner end of the sound collecting channel 511 is connected to the upper end of the longitudinal sound channel 512, and the inner diameter of the sound collecting channel 511 is greater than the inner diameter of the longitudinal sound channel 512. The lower end of the longitudinal sound channel 512 is connected to the right end of the transverse sound channel 513, the inner diameter of the longitudinal sound channel 512 is smaller than the inner diameter of the transverse sound channel 513, and the angle between the longitudinal sound channel 512 and the transverse sound channel 513 ranges from 60° to 120°. The left end of the transverse sound channel 513 is connected to the right end of the mainboard positioning groove 514, and the inner diameter of the mainboard positioning groove 514 is larger than the inner diameter of the transverse sound channel 513. The left end of the mainboard positioning groove 514 is connected to the sound transmission hole 21 of the control board 2, and the left end of the mainboard positioning groove 514 covers the right end of the sound transmission hole 21.

[0027] The sound collecting channel 511 is used to collect the sound outside the Bluetooth headset, and the longitudinal sound channel 512 and the lateral sound channel 513 are used to change the propagation direction of the sound. The mainboard positioning groove 514 is used to engage with the control board 2 and lock the positions with each other. The light groove 52 is used to embed the first indicator light 3 and the second indicator light 4, so that the light of the indicator light is completely transmitted to the light-transmitting air duct member 5.

[0028] Instructions for use: When the outside world of the Bluetooth headset generates sound, the external sound is collected by the sound collecting channel 511, then transmitted through the longitudinal sound channel 512, and then changed direction through the transverse sound channel 513 to be transmitted longitudinally. The sound then passes through the sound transmission hole 21 of the control panel 2 and is then collected by the microphone 1. When the Bluetooth headset needs to display the status, the control panel 2 will control the first indicator light 3 and the second indicator light 4 to emit light. The light of the first indicator light 3 and the second indicator light 4 is scattered by the light-transmitting air duct component 5, which increases the light-emitting area and avoids the glare of the indicator light. The entire light-transmitting air duct component 5 is in a light-emitting state, and the user can clearly see the light emitted by the light-transmitting air duct component 5 and identify the current state of the Bluetooth headset.

[0029] The above-mentioned specific implementation modes are preferred embodiments of the present invention and cannot be used to limit the present invention. Any other changes or other equivalent replacement methods that do not deviate from the technical solution of the present invention are included in the protection scope of the present invention.
