Embodiment 1

[0094] see figure 1 , the wireless noise-canceling earphone 100a according to Embodiment 1 of the present application includes an ear bag 10 and an earmuff 50 and an ear bar 70 connected to the ear bag 10 . The earmuffs 50 and the ear bars 70 are generally located on opposite sides of the ear pack 10 . When the wireless noise-canceling earphone 100 is in use, the earmuffs 50 extend into the user's ear and directly contact the user's ear. Described ear bag 10 is provided with various components and parts ( figure 1 not shown), for example, a high-frequency and / or low-frequency sound unit, a feed-back microphone, a battery, a flexible circuit board, and the like.

[0095] Wireless earphones are usually very small, and it is the focus of research and development of high-end wireless earphones to ensure the active noise reduction function while improving the sound quality in a limited volume. The wireless noise-cancelling earphones of the present application are mainly improved...

Embodiment 2

[0112] see Figure 9 to Figure 12 The wireless noise-canceling earphone 100b shown in Embodiment 2 of the present application, Figure 9 to Figure 10 Only part of the ear shell 11 is shown in the figure.

[0113] The wireless noise-cancelling earphone 100b of the second embodiment is basically the same as the wireless noise-cancelling earphone 100a of the first embodiment, refer to figure 1 It also includes the ear bag 10, the earmuff 50 and the ear bar 70 connected to the ear bag 10, and the ear bar 70 is also provided with a feed-forward microphone 71; A moving coil 20 as a low-frequency sounding unit is provided (the fixing method is the same as in Embodiment 1), and the moving coil 20 also divides the accommodating cavity 101 into a front cavity 102 and a rear cavity 104 which are not connected to each other; Part of the shell 11 protrudes into the cavity 51 of the earmuff 50 and is clamped with the earmuff 50, and the front cavity 102 is fixedly provided with a feed-bac...

Abstract

The invention provides a wireless noise reduction earphone, which comprises an earmuff shell, the earmuff shell is provided with an accommodating cavity, a moving coil is fixedly arranged in the accommodating cavity, the accommodating cavity is divided into a front cavity and a rear cavity by the moving coil, the earmuff shell is provided with a sound outlet communicated with the front cavity, a feedback microphone and a high-frequency sound production unit are fixedly arranged in the front cavity, and the high-frequency sound production unit is arranged in the rear cavity. The high-frequency sounding unit is a moving iron, a planar diaphragm or an MEMS loudspeaker; the earmuff is connected with the earmuff shell, the earmuff is provided with a cavity with two open ends, part of the earmuff shell extends into the cavity and is clamped with the earmuff, and the feedback microphone and the high-frequency sounding unit are located in the cavity of the earmuff; and the ear rod is connected with the rear cavity of the ear muff shell, and a feed-forward microphone is arranged in the ear rod. The wireless noise reduction earphone is small in size, comfortable to wear and good in sound quality effect and noise reduction effect.

Description

technical field [0001] The present application relates to the technical field of earphones, in particular to a wireless noise reduction earphone. Background technique [0002] True Wireless Stereo (TWS) earphones are popular among consumers due to their wireless, small size, and portability. With the continuous breakthroughs in electronic product technology and the fast-paced changes in the living environment, people's functional requirements for TWS earphones are also increasing. The active noise reduction function has become the standard configuration of high-end TWS headset products. At the same time, users' pursuit of the sound quality of TWS headsets is also increasing day by day. Active noise reduction is divided into single feed-forward microphone noise reduction, single feed-back microphone noise reduction and hybrid noise reduction. The single feed-back microphone noise reduction method cleans the noise, but the processing speed is slow; the single feed-forward mi...
