Embodiment 1

[0036] First, see image 3 As shown, the first embodiment of the present invention includes two earphone bodies (1) on the left and right, a connecting body (2) connecting the two earphone bodies (1), and any earphone body (1) Connected multi-channel audio cable (3). The earphone body (1) is internally equipped with a plurality of loudspeakers ( image 3 not shown), and can respectively transmit multi-channels with different sound effects, and each channel will not be mixed with each other, and has expected multi-channel quality.

[0037] For this purpose, please refer to the Figure 4 and Figure 5 , Figure 6 As shown, an exploded perspective view and a cross-sectional view of a feasible embodiment of the earphone body of the present invention include:

[0038] A shell (10) is set according to the predetermined shape and has an opening, and the periphery is provided with elongated air holes (100), and a predetermined number of multi-channel speakers (20) can be accommod...

Embodiment 2

[0048] It is known from the aforementioned first embodiment that the present invention understands the importance of each independent sound chamber during the research and development process, so the present invention further applies it in the earphones of the left and right two channels, that is, as Figure 9 As shown, in the housing (10) of any earphone body (1A) on the left and right, a loudspeaker (24) is provided, and its opening is provided with a cover (30) and a cover (40); The main technical means are the same as those of the first embodiment, but this second embodiment is aimed at setting a loudspeaker (24) inside the earphone body (1A).

[0049] The above-mentioned loudspeaker (24) is arranged in a predetermined independent sound chamber (14) according to the characteristics of its single speaker, so that it is positioned at a predetermined position or angle of the earphone body (1A).

[0050] Among them, such as Figure 9 Shown, this loudspeaker (24) is located at...

Abstract

The improved earphone includes earphone body comprising casing with opening; multichannel loudspeakers with independent sound chambers; one cover with sound holes for the loudspeakers separately and one hood over the cover. The multichannel loudspeakers includes at least prepositive main channel one, central channel one and postpositive surround sound ones set separately in the proper positions of the independent sound chambers according to their characteristics. The earphone may be used to listen high-quality multichannel music owing to its no sound mixing, less distortion and homogeneously diffused sound pressure.

Description

1. Technical field [0001] The invention relates to an earphone, in particular to an improved earphone which prevents sound waves from mixing and reduces distortion so that the earphone can listen to high-quality multi-channel music. 2. Background technology [0002] With the advancement of digital technology, digital audio-visual is gradually popularized, such as DVD audio-visual disc players or surround amplifiers, which basically have functions such as Dolby Digital or DTS decoding, which can decode digital signals and output analog signals to make speakers sound. Therefore, there is a 5.1GH AUDIO OUT audio analog output terminal on the back panel of the DVD Player or the surround amplifier, so that "TV + DVD player + surround amplifier + 5.1-channel speaker" can construct the basics of a home cinema audio-visual environment. [0003] Such as figure 1 As shown, it is the basic environment of a home cinema, and the DVD Player or surround amplifier (not shown) placed insid...
