- the lower body 120 is positioned below the upper body 110 and supports the first sound unit 200 at the lower side of the first sound unit 200. That is, the lower body 120 has a stepped portion 121 formed along the circumference of the inner circumferential surface, and a step 210 corresponding to the stepped portion 121 is formed at one side of the first sound portion 200, so that the first sound portion 200 is formed. ) May be seated on the stepped 121 and fixed.
- a plurality of fixing members 122, 123, and 124 protruding to fix the second sound unit 300 are formed on the inner circumferential surface of the lower body 120.
- the plurality of protruding fixing members 122, 123, and 124 are spaced apart from each other along the circumference of the inner circumferential surface of the lower body 120, thereby forming a predetermined space between the plurality of fixing members 122, 123, and 124.
- the space formed between the plurality of fixing members 122, 123, and 124 constitutes a part of the first movement path 130 through which the sound output from the first sound unit 200 moves, and details thereof will be described later. Let's do it.
- a coupling ring 400 may be positioned between the upper body 110 and the lower body 120 for coupling between the respective bodies, and in one embodiment, the upper body 110 and the lower body 120 are coupled to each other. It may be adhesively bonded with the ring 400.
- the first sound unit 200 is mounted on the step 121 of the lower body 120 and is accommodated in the lower body 120, and is an acoustic device that converts and outputs an electrical signal to sound.
- the first sound unit 200 may output the sound of the mid range or the high frequency range, and in one embodiment, when the first sound unit 200 outputs the sound of the mid range, the high sound range is output. It is preferable to have a relatively large diameter in comparison with the diameter of the second acoustic unit 300 to the output efficiency.
- the second sound unit 300 is disposed to be spaced apart from each other in the longitudinal direction from the first sound unit 200, and outputs sound of a band different from that of the sound output by the first sound unit 200. As described above, when the first sound unit 200 outputs sound in the mid-low range, the second sound unit 300 outputs sound in the high range.
- the first sound unit 200 and the second sound unit 300 may be configured as dynamic drivers.
- the housing 100 forms a first movement passage 130 for transmitting the sound output from the first sound unit 200 to the outside along the inner circumferential surface of the housing 100, in one embodiment the first movement
- the passage 130 may be formed by a gap between the inner circumferential surface of the lower body 120 and the outer circumferential surface of the second acoustic part 300.
- the first movement path 130 and the second movement path 140 may be implemented in the lower body 120, as shown in Figure 4 for convenience of description herein.
- the space in which the sound output from the first sound unit 200 moves is referred to as the second movement passage 140 in which the sound output from the first moving passage 130 and the second sound unit 300 moves. It will be called.
- the second sound unit 300 may be coupled to the unit cap 310 on one side, thereby forming a space in which the sound output from the second sound unit 300 moves. That is, the second moving passage 140 is formed by the unit cap 310 so that the sound output from the second sound unit 300 is separated from the sound passing through the first moving passage 130 and output.
- the unit cap 310 transmits the sound output from the second sound unit 300 in the direction of the ear tip 500 from the lower body 120.
- the length of the unit cap 310 by adjusting the length of the unit cap 310 so that the end of the unit cap 310 is spaced apart from the sound outlet 150 in the upper direction of the lower body 120, the lower body 120 through the sound outlet 150
- a wire mesh (not shown) may be provided to prevent a foreign substance from flowing into the interior of the wire, and according to the embodiment, the end of the unit cap 310 is extended to the acoustic outlet 150 to move the second movement.
- the sound passing through the passage 140 may be configured to be separated from the sound passing through the first moving passage 130.
- Ear tip 500 may be made of a silicon material for a comfortable fit of the user, any kind of material can be used if there is no difficulty in wearing.
- the circuit board (not shown) may be positioned above the first sound unit 200, one side of which is connected to the first sound unit 200 and the second sound unit 300 in parallel, and the other side of the power cable It is connected to the 600 to supply the electrical signal and power necessary for the sound output.
- FIG. 4 shows a process in which the sound output from the first sound unit 200 and the second sound unit 300 is moved along the first and second movement paths 130 and 140 to be discharged to the outside.
- the sound output from the first sound unit 200 and the second sound unit 300 is moved along the first and second movement paths 130 and 140 to be discharged to the outside.
- the mid-low range sound output from the first sound unit 200 is lowered along the space (that is, the first moving passage 130) formed between the inner circumferential surface of the lower body 120 and the outer circumferential surface of the second acoustic unit 300.
- the body 120 moves downward, passes through a space formed between the plurality of fixing members 122, 123, and 124, and moves toward the sound outlet 150 to be output to the outside.
- the mid-low range sound is output from the first sound unit 200 and the high-range sound is output from the second sound unit 300. That is, as the sound of the high band is moved to the outside through the second moving passage 140 in the unit cap 310 in the second sound unit 300, the sound is not separately mixed with the sound of the low and mid band, and is discharged separately. The output is made to the outside by moving to 150.
- the present invention is independent of the sound having a different sound range through the first moving passage 130 formed in the lower body 120 of the housing 100 and the second moving passage 140 formed by the unit cap 310. Since it can be separated and output, the stereo performance is improved, thereby providing a three-dimensional sound to the listener.
