Description

  The present invention can enjoy music while carrying it while it is worn on the user's body, for example, and can further enhance the visual atmosphere by changing the light emission state of the LED group according to the music. Free portable audio system.

  As this type of audio system, a portable CD player, a portable IC player, and the like are widely known. This type of audio system listens to sound signals reproduced by a player via earphones or headphones. In the portable audio system of the present invention, a group of LEDs that are blinked and controlled in accordance with an audio signal are incorporated in a speaker unit. There, the LED group is blinked according to the change of the audio signal, and the light emission state of the LED group is changed according to the music. A similar speaker system is also disclosed in Patent Document 2. However, Patent Documents 1 and 2 are speaker systems that are used in a stationary state, and cannot be used by carrying them on a part of the body.

  The portable audio system of the present invention is carried with the speaker unit mounted on the upper arm, for example, and simultaneously drives the speaker to emit a group of LEDs so that the speaker unit can also serve as an accessory having a light emitting function. However, an accessory having such a light emitting function is known from Patent Document 2, for example. There, a necklace is composed of a plurality of decorative bodies, and a group of light emitting elements (LEDs) are arranged inside a decorative body made of transparent plastic material simulating diamonds, and the light emission state of the group of light emitting elements is controlled. It is possible to control blinking based on.

The liquid crystal display 8 is provided. Although not shown, an operation unit for controlling power on / off, playback / stop, volume increase / decrease, etc. is provided on the outer surface of the IC recorder 5. An IC memory for recording music data, audio data, and the like is built in the IC recorder 5. The IC memory may be an IC card that is detachable from the IC recorder 5, as represented by an SD card, or may be an IC memory that cannot be taken out.

  As shown in FIG. 2, the speaker unit 2 includes a disk-shaped speaker case 11, a speaker 12 incorporated in the speaker case 11, a mounting tool 13 for mounting the speaker case 11 on a user's body, and a speaker case. 11 and a light emitting structure 15 using a group of LEDs 14 that are controlled to blink according to an audio signal output from the sound source unit 1 as a light source. The speaker case 11 is composed of a container-shaped case main body 11a made of a plastic molded product and a case lid 11b that closes the opening surface of the case main body 11a. A pair of connecting frames 17 is formed. The case lid 11b is fastened and fixed to the case main body 11a with screws.

  A ring-shaped partition wall 18 that accommodates the speaker 12 and four mounting bosses 19 project from the inside of the case body 11a. The board 20 and the speaker 12 are engaged and fixed to these mounting bosses 19. It is. The speaker 12 is a cone-type dynamic speaker, and the back side thereof is sealed with a previous partition wall 18. A control circuit 21 for controlling the light emission pattern of the group of LEDs 14 is mounted on the substrate 20. The control circuit 21 causes the light emission pattern of the group of LEDs 14 to blink in response to a change in the scale or rhythm of the audio signal. Can be controlled. The light emitting structure 15 is configured by the LED 14, the substrate 20, and the control circuit 21.

  Plural types of light emission patterns of the group of LEDs 14 are prepared, and can be changed autonomously or according to the user's preference. The substrate 20 is formed in a ring shape, a group of LEDs 14 having different emission colors are mounted on the outer surface thereof at regular intervals, and electronic components constituting the control circuit 21 are mounted on the inner surface side. In this embodiment, sixteen types of LEDs 14 that emit light of red, blue, yellow, green, amber, and white are mounted on the substrate 20. A jack 30 for inserting and connecting the pin plug of the connection cord 3 is provided on the peripheral side surface of the case body 11a.

  A circular opening 23 for sending a sound wave output from the speaker 12 is opened at the center portion of the case lid 11b, and a light projection window 24 corresponding to each LED 14 is opened around the opening. The through holes 23 are covered with a breathable fabric 25, and all the projection windows 24 are closed with a ring-shaped transparent window plate 26 fixed to the inner surface of the case lid 11b (see FIG. 2). On the outer edge of the case lid 11b, an operation unit 27 provided on the IC recorder 5 for controlling playback / stop, volume increase / decrease, feed skip / return skip, and the like is provided. That is, the speaker unit 2 also serves as a remote controller for the IC recorder 5. Of these operation units 27, each time the reproduction operation unit 27 is pressed, the light emission pattern of the group of LEDs 14 can be selected and changed according to the user's preference.

  The mounting tool 13 includes a belt 13a formed of a cloth, a pair of male and female hook-and-loop fasteners 32a and 32b that are attached to the back surface of one end of the belt 13a and the surface of the belt 13a. The wearing tool 13 can change and adjust the winding length of the belt 13a to an arbitrary amount by changing the fastening position of the male surface fastener 32a with respect to the female surface fastener 32b.

  In the audio system configured as described above, for example, as shown in FIG. 3A, the sound source unit 1 is stored in the chest pocket of the shirt, and the speaker unit 2 is mounted on the upper arm with the mounting tool 13, or FIG. As shown in b), the speaker unit 2 can be carried and used while being mounted on the forearm by the mounting tool 13. Moreover, as shown in FIG.3 (c), it can be used in the state which attached the speaker part 2 to the waist belt, and in that case, it can attach to the connection frame 17 through a waist belt.

  As described above, when the IC recorder 5 is operated with the speaker unit 2 mounted on a part of the user's body, the music output from the speaker 12 can be enjoyed simultaneously by a plurality of accompanying persons. By changing the light emission state of the LEDs 14 according to music, the atmosphere can be visually enhanced. Furthermore, even when music is being reproduced, a natural conversation can be performed between a person carrying the audio system and another accompanying person.

  In addition, when the audio system is used at night, the speaker unit 2 can be made to function as a decorative body that emits light by multicolored light emitted from the group of LEDs 14, thereby carrying the audio system. Emphasize the presence of the user and accompanying person. If the IC recorder 5 is held with one hand and voice is input from the microphone 7, the voice can be amplified simultaneously with music and enjoyed like karaoke. Of course, in a state in which the reproduction of music is stopped, only the voice input from the microphone 7 can be amplified.

  FIG. 4 shows another embodiment of the speaker unit 2. In this case, as shown by an imaginary line, a mounting tool 13 is configured by a leaf spring attached in a round tube shape and a cloth cover 34 covering the outer surface, and a group of LEDs 14 are mounted on the outer surface of the cover 34. I did it. A group of LEDs 14 is mounted on a flexible printed circuit board, and its outer surface is covered with a transparent cover. Therefore, when the mounting tool 13 is wound around the arm and mounted, the LED 14 group can be curved and deformed along the peripheral surface of the mounting tool 13 together with the flexible printed circuit board.

  In the above-described embodiment, the speaker case 11 is formed in a circular shape. However, the speaker case 11 may be formed in a polygonal shape or an elliptical shape. If necessary, it can be formed into an external shape simulating animals, insects and flowers. The sound source unit 1 can be composed of an existing player such as a CD player or an MD player in addition to the IC recorder 5. As the speaker 12, a cheaper piezoelectric speaker can be applied. In this case, a plurality of speakers 12 can be used to make music to be reproduced stereo. The mounting tool 13 does not need to be formed in a belt shape, and can be formed in a clip shape depending on the mounting site, or a string or chain for hanging on the neck can be used as the mounting tool 13.

  When the audio signal of the sound source unit 1 is transmitted by FM waves, the connection cord 3 can be omitted and wireless can be realized.
