FIG. 14 is a perspective view of a first lower case according to an embodiment of the present invention, and FIG. 15 is a perspective view of a second lower case according to an embodiment of the present invention.

The lower case 410 and 420 in the embodiment of the present invention is cylindrical and includes a first lower case 410 provided on the upper side and a second lower case 420 coupled to the lower side of the first lower case 410, . The first lower case 410 and the second lower case 420 are formed with a hollow portion, and the hollow portion is provided with a lower speaker module 490. The lower speaker module 490 is opposite to the forming direction of the upper speaker module 280. That is, the sound generated by the lower speaker module 490 is arranged to be emitted to the outside toward the lower side. At this time, although the upper side of the first lower case 410 is hermetically closed, the lower part is opened and the side surface is formed with a through hole 411 in both directions.

The lower sound output unit 400 includes a lower speaker module 490. A diaphragm 491 is formed below the lower speaker module 490 and a plurality of through holes 492 are formed on the upper side. At this time, sound may be output to the front face of the diaphragm 491 by the vibration of the diaphragm 491, but the vibration by the diaphragm 491 may be transmitted to the rear face of the lower speaker module 490, .

In an embodiment of the present invention, the anion generating module 390 may be provided on the lower acoustic output unit 400 to generate negative ions.

 The lower sound output unit 400 is provided with a diaphragm 491 vibrating up and down and a case in which the diaphragm 491 is convex downward is referred to as a negative pressure, (-) sound pressure.

As described above, in the embodiment of the present invention, the diaphragm 491 of the lower acoustic output unit 400 causes a difference in air pressure before and after the lower acoustic output unit 400. The anion generation module 390 causes the anion generated by the anion generation module 390 to be discharged to the outside through the acoustic hole 103 by the air pressure when the lower sound output unit 400 operates .

In this case, the sound output apparatus 100 includes a state (hereinafter, referred to as a first state) in which sound is output while the lower sound output unit 400 and the anion generation module 390 operate simultaneously, (Hereinafter referred to as a second state) in which the negative ion generating module 390 is operated and the negative ion generating module 390 is not operated and the lower acoustic wave Only the output unit 400 may operate (hereinafter referred to as a third state).

In the first state, the lower sound output unit 400 and the anion generation module 390 can be simultaneously turned on when the sound output apparatus 100 is operated, and the lower sound output unit 400 When activated, the negative ion generating module 390 may be operated by itself. Since the negative ion generating module 390 is difficult to volatilize the negative ions generated without operation of the lower acoustic output unit 400, the operation of the negative ion generating module 390 is controlled by the operation of the lower acoustic output unit 400 And can be dependent on whether or not. That is, as shown in FIG. 2B, in the first state, the sound L2 and the anion L3 may be discharged to the outside through the acoustic hole 103. [

However, the present invention is not limited thereto, and the negative ion generating module 390 may be operated without the lower acoustic output unit 400 outputting sound as in the second state.

The acoustic signal (electric signal) input to the lower sound output unit 400 may cause the diaphragm 491 to generate a sound wave that is out of the range of the audible frequency. If the sound wave generated by the diaphragm 491 is out of the range of the audible frequency, it may be felt that the sound is not output by the lower sound output unit 400. In this case, it becomes possible to implement the second state. For example, if the speaker module 490 can be implemented up to 35 KHz, if a sound signal generating a sound wave of 20 to 35 KHz, which is an audio frequency range, is inputted, the sound wave is generated by the lower sound output unit 400, So that only the negative ion generating module 390 is felt to operate. That is, strictly speaking, the sound is output even in the second state, but the user can not hear. In other words, in the second state, as shown in FIG. 2A, the sound does not flow out through the acoustic hole 103, and only negative ions are discharged to the outside through the acoustic hole 103.

The first state is a case where the user hears the sound by the diaphragm 491 and the second state is the case when the user hears the sound by the diaphragm 491 Which means that the user can not hear the sound caused by the sound.

Further, only the lower acoustic output section 400 may be operated and the negative ion generating module 390 may not be operated. At this time, the general sound output apparatus 100 operates in the third state.

The sound output apparatus 100 according to an embodiment of the present invention includes an anion generation module which is spaced apart from a lower sound output unit 400 provided at an inner lower portion of the outer case 101 to generate negative ions 390 (ionizer module).

The anion generation module 390 functions to merely generate negative ions, but does not have a separate additional device for volatilizing the generated negative ions. In order to further disturb the negative ions, a device such as a fan is required. However, in the embodiment of the present invention, no configuration for volatilizing the negative ions is added.

The lower speaker module 490 is formed with a plurality of through holes 492 at an inward portion thereof and outputs sound toward the lower portion thereof. A diaphragm 491 is provided at a portion of the lower speaker module 490 facing the outside to allow air to pass through the through hole 492. That is, the negative ions generated in the negative ion generating module 390 are discharged to the outside through the acoustic hole 103 by the air pressure caused by the vibration of the diaphragm 491.

The position of the negative ion generating module 390 may be formed adjacent to the upper and lower acoustic output units 400. For example, as shown in FIGS. 2A and 2B, it may be provided on the upper side of the lower acoustic output unit 400 and may be provided on the lower side of the upper acoustic output unit 200 It is possible.

At this time, the upper acoustic output unit 200 and the lower acoustic output unit 400 may be separated into spaces by the elevator mechanism, more specifically, the latch plate. More specifically, the sound generated from the upper sound output unit 200 and the lower sound output unit 400 can be reduced by interference with each other by the latch plate.

The lower case 410 and 420 are formed inside the outer case 101 so that the lower case 410 and 420 are closed by the negative ion generation module 390. That is, the lower cases 410 and 420 and the anion generation module 390 are formed to surround the upper side of the lower sound output unit 400 to block the movement of air.

More specifically, the lower end of the first lower case 410 is formed to be convex upward, and a recess portion 412 for sealing the lower end of the first lower case 410 is formed, and the recess portion 412 412 may be provided with the negative ion generating module 390. In this case, the lower end of the first lower case 410 is hermetically closed. Alternatively, although not specifically shown, an opening may be formed in the lower end of the first lower case 410, And the path L3 through which the negative ions can move can be ensured by being closed by the generating module 390. [

In an embodiment of the present invention, an anion generating module 390 is formed on a lower side of the first lower case 410, and an anion generated from the anion generating module 390 is formed on the second lower case 420 A through hole 422 is formed so as to be discharged to the outside.

As described above, the anion generating module 390 is hermetically sealed, and the downward sound generating module 390 is spaced apart from the lower sound output part 400 by a predetermined distance to form an anion moving path L3 as shown in FIG. 2B .

In addition, the size of the bottom surface of the first lower case 410 may vary depending on the size of the anion generation module 390. For example, when the negative ion generating module 390 is small, the cross section of the negative ion generating module 390 should be gradually decreased toward the upward direction. That is, the lower end of the first lower case 410 has a taper shape whose cross section gradually decreases toward the upper side.

The second acoustic path forming unit 440 is formed similarly to the upper acoustic output unit 200 in order to allow the sound generated from the lower acoustic output unit 400 to flow downward. That is, the upper and lower sides of the second lower case 420 are open, the lower speaker module 490 is received inside the second lower case 420, and the ends of the lower speaker module 490 A second acoustic path forming part 440 for introducing the acoustic path L2 output from the lower speaker module 490 to the outside is formed.

More specifically, when the decoupling plate 210 is pressed and the power is turned on, when the Bluetooth display unit 212 is touched for a predetermined time, the acoustic output apparatus 100 enters the pairing mode. At this time, when entering the pairing mode, it is blinked twice for 2 seconds as described above, and is outputted to the list of electronic devices which can be paired with the second electronic device or the electronic device which has been paired before. At this time, it is possible to perform the pairing by inputting the password to the second electronic device or the electronic device which has been previously paired. At this time, the step of inputting the password may be omitted in some cases.

Although the Bluetooth pairing mode has been described above, the same operation can also be performed in the case of pairing by Wi-Fi, so a detailed description will be omitted below.

Then, after a while, the first sound output device 100a and the second sound output device 100b can be paired with one electronic device 600 at the same time to enjoy stereo sound. When the stereo sound is to be stopped, the Bluetooth display unit 212 and the volume up button 214a of the first sound output apparatus 100a or the second sound output apparatus 100a are simultaneously pressed, or the Bluetooth display unit 212 The volume down button 214b is pressed simultaneously for 2 seconds (long touch). For example, when the Bluetooth display unit 212 and the volume up button 214b of the second sound output apparatus 100a are simultaneously pressed, the pairing of the second sound output apparatus 100b and the electronic apparatus 600 may be interrupted . In the above description, the pairing is performed using the volume up button 214a or the volume down button 214b.
