  The present invention relates to an ear-mounted earphone, and more particularly to an ear-mounted earphone that allows easy switching of sound quality.

  Some head-mounted headphones and ear-mounted headphones that are excellent in sound quality and used for music appreciation, etc. can be adjusted in sound quality. Head-mounted headphones have left and right speaker units that have a structure in which speakers are placed inside one side of a housing made of a molded product such as synthetic resin and pads with cushion materials such as urethane attached. Are combined. In addition, the ear-mounted earphone has a structure in which the left and right speaker units are separately hung on the left and right ears with hooks adapted to the shape of the ear.

  Of the sound frequencies played by head-mounted headphones and ear-mounted headphones, especially when considering low-frequency sounds, especially heavy low-frequency sounds, the housing has a sealed structure and some It has been investigated that there is a difference in the sound pressure level generated when a communication hole with the outside is provided. Therefore, a mechanism for providing a hole communicating with the outside of the housing and opening and closing the hole in accordance with the type of music or the taste of the viewer has been considered and put into practical use.

  A conventional sound quality switching mechanism for headphones is disclosed in Japanese Utility Model Laid-Open No. 5-18193.

  FIG. 6 is a cross-sectional view showing a sound quality switching mechanism for headphones disclosed in the above-mentioned publication. In the figure, a speaker unit (speaker unit) 102 is accommodated in a housing 101. A pad is attached to an outer periphery of a lower part (not shown) of the housing to form an ear pad. A part of the housing 101 is formed in a recess 103. Two protrusions 104 and 105 are provided at a predetermined distance from each other, and metal rings 106 and 107 are attached to the respective outer peripheral portions. Yes. One of the two protrusions 104 and 105 is provided with a hole 108 communicating with the inside and outside of the housing. The seesaw switch 109 rotates about a shaft 110 supported by the housing 101 by a structure (not shown). Magnets 111 and 112 are attached to portions of the lower surface of the seesaw switch 109 corresponding to the protrusions 104 and 105 of the housing 101. Both end portions of the seesaw switch 109 are formed in the push button portions 113 and 114, and the user presses these portions with a finger.

  In the headphone configured as described above, when the low frequency characteristics are to be changed, either the push button 113 or 114 of the seesaw switch 109 is pressed to attract the ring 106 and the magnet 111 or the ring 107 and the magnet 112. . In the state shown in the figure, the ring 107 and the magnet 112 are attracted, and the hole 108 provided in the housing 101 is closed by the seesaw switch 109 functioning as a lid member. In this case, the headphones emit a sound in a state where the housing 101 is in a sealed type.

Next, when the push button 113 of the seesaw switch 109 is pressed, the ring 106 and the magnet 111 are attracted, and the magnet 112 is detached from the ring 107. As a result, the hole 108 of the housing 101 opens to the outside, so that the housing 101 becomes a non-sealing type and generates sound of sound quality corresponding to the non-sealing type.

According to the recognition, the switching state of the sound quality of the sealed type or the non-sealed type can be easily confirmed.

  According to the second aspect of the invention, in the ear-hook type earphone according to the first aspect, since the protrusion is provided on one of the push button portions at both ends, the confirmation of the switching state of the sound quality of the sealed type or the non-sealed type is confirmed. Is even easier.

  Hereinafter, the best mode of the present invention will be described with reference to the drawings. 1 to 5 are diagrams showing a configuration of an earphone according to the best mode of the present invention, FIG. 1 is a perspective view, FIG. 2 is an exploded perspective view, and FIGS. 3 (A) and 3 (B) are views. FIGS. 4A and 4B are front views and cross-sectional views taken along the line XX, respectively. FIG. 5A and FIG. 5B respectively illustrate the sound quality switching operation. It is sectional drawing demonstrated.

  The earphone 1 is composed of an earphone main body 2 and an ear hook 3 attached to the earphone main body 2.

  The earphone main body 2 includes a first housing member 4, a second housing member 5 coupled to the housing member 4 to form a housing, and a decorative plate 6 attached to the second housing member 5.

  The first housing member 4 is a synthetic resin molded article formed in a substantially cylindrical shape, and the speaker unit 8 is disposed in one concave portion partitioned by the partition plate 7 in the middle, and the other concave portion 4a is provided. It is open. A protection plate 15 having many holes for sound emission is attached to the front surface of the speaker unit 8. In addition, ear pads 9 are attached to the first housing member 4 so as to cover the protective plate 15 side.

  The second housing member 5 is made of a non-magnetic metal, for example, aluminum, which is formed in a substantially disk shape, and one end of the hook 3 is rotated by a predetermined angle to a mounting portion 5a that is integrally formed protruding from the outer periphery thereof. It is mounted movably. On one surface of the second housing member 5, a through hole 5b, a ring-shaped magnet 10 fitted and fixed to the inner periphery of the through hole 5b, and a ring embedded at a predetermined distance from the through hole 5b A magnet 11 and a long groove 12 formed between the ring magnets 10 and 11 are provided.

  The seesaw switch 13 rotates about a shaft 13a fitted and supported in the long groove 12. A disk-shaped metal plate 14 is attached to a portion corresponding to the ring-shaped magnets 10 and 11 on the lower surface of the seesaw switch 13.

The opening 6a holds the shaft 13a of the seesaw switch 13 at the middle thin portion of the gourd type, thereby preventing the seesaw switch 13 from protruding and pinching with the second housing member 5.

  The earphone 1 thus configured can switch the sound quality according to the type of music or the taste of the viewer by the sound quality adjusting mechanism described above. Hereinafter, a sound quality switching method will be described.

  When the sound quality is to be changed, the metal plate 14 and the ring magnet 10 or 11 are attracted by pressing one of the push button portions 13b and 13c of the seesaw switch 13.

  First, when the push button portion 13c is pushed as shown in FIG. 4A, the metal plate 14 below the push button portion 13c is attracted to the ring-shaped magnet 10 as shown in FIG. The through-hole 5b provided in 5 is closed. In this case, the ear-mounted earphone 1 emits a sound in a state where the housing is in a sealed type. That is, the inside of the housing, that is, the recess 4a is hermetically sealed, the vibration of the diaphragm of the speaker unit 8 is reduced, and the sound quality characteristic of a thin and sharp natural high range is reproduced.

  Next, when the push button portion 13b of the seesaw switch 13 is pushed as shown in FIG. 4B, the metal plate 14 below the push button portion 13b is attracted to the ring-shaped magnet 11 as shown in FIG. 5B. At the same time, the metal plate 14 below the push button portion 13 c is detached from the ring-shaped magnet 10. As a result, the through-hole 5b provided in the second housing member 5 opens to the outside through the opening 6a of the decorative plate 6 as indicated by the arrow, so that the housing becomes a non-sealing type and the sound quality corresponding to the housing is made. Will occur. That is, when the inside of the housing, that is, the recess 4a is unsealed and opened to the outside, the diaphragm of the speaker unit 8 shakes, and the sound quality characteristic of heavy bass is reproduced.

  Then, sound quality can be switched by operating the seesaw switch 13 with a finger in a state where the earphone 1 is actually put on the user's ear. At that time, since the push button portions 13b and 13c of the seesaw switch 13 are different in size, it is possible to recognize which push button portion is based on the difference in size when touched with a finger. Alternatively, the switching state of the non-sealed sound quality can be easily confirmed.

  Further, since the large push button portion 13c is provided with a projection 13d, it is possible to more easily recognize which push button portion by touching the projection 13d with a finger. The sound quality switching state of the sealed type or the non-sealed type can be easily confirmed.

  Therefore, even if the state of the sound quality switching mechanism is not visually recognized, it is possible to easily confirm the sound quality switching state of the sealed type or the non-sealed type.

  As described above, the best mode of the present invention has been described. However, the present invention is not limited to this, and various modifications and applications are possible.
