The technical scheme for further limiting the utility model comprises the following steps:

the height of the three through holes on the side wall of the sound amplifying main body is lower than the height of the cone body at the center of the inner cavity of the sound amplifying main body.

The loudspeaker support have tubaeform casing, the public address main part embedding in tubaeform casing bottom.

The horn high pitch type loudspeaker is arranged in front of the circular moving coil type loudspeaker and is fixedly installed with the sound cavity wall through the supporting rib.

The utility model has the beneficial effects that: the utility model comprises a circular moving coil type loudspeaker and a horn high pitch type loudspeaker, which are respectively used for playing high pitch and low pitch through the organic matching of frequency dividers, thereby ensuring that each detail of music is restored with high fidelity. Three in-ear moving-iron horns are inserted into copper horns in a star shape to form independent horn-type high-pitched tones, and the horn-type high-pitched tones are specially used for a headset. Through actual audition and test technical index, this bugle high pitch has subversive promotion to the high frequency detail in the music signal, and perfect show the music detail provides a new product design thinking for HiFi stereo set fevers. The headset fundamentally meets the requirements of HiFi pursuits on the headset, and has wide market prospect and economic benefit.

Detailed Description

The structure of the present invention will be further described with reference to the accompanying drawings and preferred embodiments of the present invention.

Referring to fig. 1 to 5, the disclosed HiFi headset treble assembly structure with horn treble includes a left housing 1, a right housing 2, and a headband body 3; the left shell 1 and the right shell 2 are respectively connected with the left end and the right end of the headband body 3, the inner side surfaces of the left shell and the right shell are respectively provided with an earmuff 4, and the positions corresponding to the cavities of the earmuffs 4 are provided with sound outlet through holes 5; the sound cavities are respectively arranged in the left shell and the right shell, and a circular moving-coil type loudspeaker is arranged in the sound cavity; horn high pitch type loudspeakers are respectively arranged in the sound cavities in the left shell and the right shell; the circular moving coil type loudspeaker and the horn high pitch type loudspeaker are used for playing bass and treble respectively, and each detail of high-fidelity restored music is guaranteed.

Because the ear muffs 4 of the headset cover ears, the middle part of the headset cover ears, the sounding point of the loudspeaker of the headset has a certain distance with auditory nerves at the inner sides of the ears, but the common in-ear tweeter has fast attenuation of sound pressure and can not be used, in order to realize that the high sound output from the sound cavity can be transmitted to the auditory nerves at the inner sides of the ears through the cavity of the ear muffs 4, the horn tweeter specifically comprises a loudspeaker bracket 61, a copper horn 62 and three moving-iron loudspeakers 63; copper horn 62 locate horn bracket 61 on, copper horn 62 including loudspeaker form public address main part 621 with locate the conical body 622 at public address main part 621 inner chamber center, evenly have three through-hole respectively at the lateral wall of public address main part, three move indisputable loudspeaker 63 respectively by public address main part 621 stretch into the three through-hole on the lateral wall of public address main part outward in, horn bracket 61 respectively with three draw-in groove 611 of moving indisputable loudspeaker cooperation joint, three move indisputable loudspeaker 63's main part joint respectively fix in the three draw-in groove on horn bracket.

In order to avoid mutual interference of sound waves of the three moving-iron horns 63, the three through holes on the side wall of the sound amplifying main body are positioned at a height lower than the height of the conical body 622 in the center of the inner cavity of the sound amplifying main body.

In order to further amplify the treble, the speaker holder 61 has a speaker-shaped housing, and the speaker body 621 is embedded in the bottom of the speaker-shaped housing.
