Abstract

The utility model belongs to a device which is used for closed-circuit listening and monitoring in the acoustic technology, relating to a multiple sound channels earphone. The earphone is composed of a plurality of sounder, that is the relevant positions in the left and the right ear cover shells are provided with seven groups of sounders of upper, middle, lower, center, front, rear, front 45 degrees and rear 45 degrees, and each group is joined a three-core plug-in unit. Compares with the single sounder earphone which can only receive the double sound channels in the current market, the multiple sound channels earphone has better and more performances. The utility model forms multi-position transmission of the sound acoustic wave, and keeps the reflection force of the auricle, space stereophonic environment is generated in the ear cover, and the listener can flexibly regulate and lonely appreciate various multiple sound channels music according to own will. The earphone can realize the monitoring of multiple sound channels places.

Description

Multi-sound-channel earphone

Technical field

The utility model relates to sound technique, belongs to closed circuit listening to or monitoring device.

Background technology

The earphone of Chu Shouing nearly all is that a pronunciation device respectively is installed in the earmuff housing of the left and right sides in the market, and the earphone that single acoustic generator that this suitable dual track is used is made can not satisfy the closed circuit Music Appreciation and the necessary monitoring requirement of sound channel system more than the sound technique of development day by day.

Summary of the invention

The purpose of this utility model is exactly to provide a kind of at above-mentioned situation to carry out the closed circuit multi-sound-channel earphone of place in order to monitor of listening to and amplify for multi-channel system.

In view of human brain is the synthetic effect of two ear perception sound wave directions (comprising the reflection of auricle) and dynamics to the perception of acoustic image, so the technical solution of the utility model is as follows: this earphone part same as the prior art is also to comprise steel wire hoop, the cushion cover, left and right sides earmuff housing, lead-in wire, component parts such as acoustic generator, and different be that the acoustic generator that comprises in the earmuff housing of the left and right sides is just not single, and include a plurality of, and their distribution modes in housing be by on, down, before, after, the center, preceding 45 °, the 45 ° of positional alignment in back, be that left and right sides earmuff housing has 14 acoustic generators, the shared same three core plug-in units of two acoustic generators of left and right sides correspondence position.Both sides were equipped with the adjustable plate of several holes before and after left and right sides earmuff housing was outer, and its aperture and steel wire hoop two ends pin thickness match, and each is regulated on the orifice plate and generally establishes three holes, upper, middle and lower.In addition, the inner edge of cushion cover and the basic kissing of auricle outer rim form.

Good effect of the present utility model:

Because the utlity model has seven groups of acoustic generators places by the different azimuth symmetry, and auricle is not squeezed in the earmuff housing and is normal morphology, kept the albedo of people's auricle to sound, thereby help span stereophonic sound image in earmuff, when having satisfied the music-lover and solely listen the music of appreciating different sound channels at any time, can not constitute interference effect again to other people.In addition, also can implement monitor the multichannel place that amplifies.

Embodiment:

As Fig. 1, in the earmuff inner casing of the left and right sides respectively by on 4, down 5, center 3, preceding 6, back 9, preceding 45 ° 7, back 45 ° 8 position install acoustic generator and have screw 13 fixing.Wherein preceding 45 °, back 45 ° of angles that are meant the center vertical line of these two sonorific center vertical lines and center acoustic generator 3 are 45 ° respectively, see Fig. 2.Left and right sides earmuff inner casing has 14 acoustic generators, and two acoustic generators of two earmuff opposite positions connect little three core plug-in units altogether.When listening to common double sound channel sound equipment, adopt the central. set acoustic generator; As listen to 2.1 sound channels and then add down 5 winding basss again; As answer 5.1 sound channel systems, and then adopt preceding 45 ° 7, back 45 ° 8 groups, last 4 windings are mid-, 5 winding bass pollakicoprosis can down.Certainly the listener can require according to the sense of hearing of oneself to apply in a flexible way.In addition, the listener can also regulate steel wire hoop end pin and insert position, hole, the upper, middle and lower pressure spot of adjusting orifice plate 11 with head dummy that is suitable for oneself and the comfort level that keeps auricle.

Claims

1, a kind of multi-sound-channel earphone comprises steel wire hoop (1), cushion cover (2), earmuff housing (11), lead-in wire (10), acoustic generator (F), it is characterized in that in its left and right sides over body case acoustic generator not being housed just, but has comprised a plurality of acoustic generators.

2, multi-sound-channel earphone according to claim 1, it is characterized in that respectively comprising seven acoustic generators (F) in its left and right sides earmuff housing, and they the distribution mode of inner casing be by on (4), (5), preceding (6), back (9), preceding 45 ° (7), back 45 ° (8), center (3) positional alignment down.

3,, it is characterized in that its shared same three core plug-in units of the left and right sides two acoustic generators of earmuff housing correspondence position according to claim 1 and 2 described multi-sound-channel earphones.
