Embodiment Construction

[0009] Such as figure 1 As shown, the present invention refers to a multi-driver in-ear earphone. A sound guiding tube 101 , a sound guiding tube 102 and a housing cavity 103 are arranged in the housing 10 , and the housing cavity 103 is connected to the sound guiding tube 101 through the sound guiding tube 102 . A high-frequency driver 20 is arranged in the housing 10 , and the audio output port 201 of the high-frequency driver 20 is arranged at the sound guide tube 101 . The housing 10 is also provided with a low-frequency driver 30 , behind the vibrating diaphragm 301 of the bass driver 30 is a driver cavity 311 , and the driver cavity 311 is connected to the housing cavity 103 through a small hole 312 . The driver cavity 311 and the small hole 312 form a second-order acoustic low-pass filter, and the casing cavity 103 and the sound guide tube 102 form another second-order acoustic low-pass filter.

Abstract

A multi-drive in-ear headset including moving-coil bass comprises a housing. The housing has at least one tweeter and a bass driver. The sound waves emitted by the bass driver pass through a second-order acoustic low-pass filter consisting of a cavity and a small hole on the back of the diaphragm and then through a second second-order acoustics low-pass filter consisting of the housing cavity and the sound guiding tube, and then are fused with the sound waves generated by a high-frequency driver and output to the human ears. The beneficial effects are as follows: 1, the two second-order acoustic low-pass filters are used to attenuate the high-frequency components emitted by the low-frequency driver, and reduce the interference with the sound waves emitted by high-frequency driver; 2, the structure is simple, the headset is conducive to manufacturing, the production cost is lowered, product competition in the market is benefited.

Description

technical field [0001] The invention relates to an earphone multi-driver in-ear earphone, in particular to a multi-driver in-ear earphone which uses a moving coil type electroacoustic generator to make bass. Background technique [0002] The low frequency of ordinary multi-driver in-ear headphones with coil transducers as the bass is not specially processed. US patents US 8280094 B2 and US 8311259 B2 have announced several designs for setting different sound channels for different drivers, but for low frequency The filtering is not specially processed. In this case, it is easy to cause the different drivers to overlap too much at certain frequencies and affect each other, affecting the sound quality of the headphones. The present invention attempts to use an acoustic low-pass filter to filter the low-frequency driver to attenuate the high-frequency components reproduced by it, thereby reducing the mutual interference between different drivers.
