Description

  The present invention relates to a reflective loudspeaker.

  In recent years, mobile phone functions have been diversified, and consumers' demand for mobile phone functions, such as multimedia functions, has been increasing. Currently, audio playback is one of the most commonly used functions in mobile phones, but it is usually necessary to connect the mobile phone to an external speaker in order to improve the volume and sound quality of the speaker of the mobile phone itself. There is. However, an external speaker is inconvenient because it can be used only after it is connected to a power source indoors.

  The present invention has been made in consideration of the above problems, and an object thereof is to provide a reflective loudspeaker that is convenient to use.

  To achieve the above object, a reflective loudspeaker according to the present invention includes a pedestal and a loudspeaker mounted on the pedestal. A bracket for mounting the electronic device is provided inside the loudspeaker, and a reflective wall capable of reflecting sound is formed on the inner surface of the loudspeaker, and the reflective wall has a semi-elliptical spherical shape. It has a structure.

  The reflecting wall of the loudspeaker of the reflective loudspeaker according to the present invention employs a semi-elliptical spherical chamber structure, and the sound emitted from the mobile phone that is obliquely fixed inside the loudspeaker is transmitted to the reflective wall. When propagated, it is reflected to the outside of the loudspeaker by the reflecting wall and gathers at one point. Thereby, since the reflection type loudspeaker of the present invention can function as a speaker without being energized, it is convenient to use and can save electric energy.

It is a perspective view of the reflection type loudspeaker of this invention. It is a figure which shows the state which has mounted | wore the mobile telephone with the reflection type loudspeaker shown in FIG. It is sectional drawing along the III-III line of the reflection type loudspeaker shown in FIG.

  As shown in FIG. 1, the reflection type loudspeaker according to the present invention is used to amplify the volume produced by an electronic device such as a mobile phone and improve the sound quality. The reflection type loudspeaker includes a pedestal 10 and a loudspeaker 20.

  The pedestal 10 includes a base 11 and a loading body 12. In the present embodiment, the loading body 12 protrudes from the upper surface of the base 11 and supports the loudspeaker 20. As a modification, in order to adjust the angle of the loudspeaker 20, the loader 12 may be rotatably installed on the base 11 via a connecting shaft.

  2 and 3 together, the loudspeaker 20 is a cover having an opening, and is made of a material having an excellent sound reflection effect. The loudspeaker 20 according to the present invention has a structure formed by cutting the ellipsoid in half along the short axis of the ellipsoid. Specifically, the loudspeaker 20 includes an opening end 21, a reflecting wall 22 (inner surface of the loudspeaker 20), and an outer peripheral wall 23 (outer surface of the loudspeaker 20) provided on the opposite side of the reflecting wall 22. The loader 12 is connected and fixed to the bottom of the outer peripheral wall 23 of the loudspeaker 20. In order for the loudspeaker 20 to transmit better sound, the loading body 12 supports the opening end 21 at a predetermined angle with respect to the base 10 so that the opening end 21 faces slightly upward. The reflection wall 22 is a semi-elliptical spherical chamber, and includes an arcuate end portion 221 positioned opposite to the opening end 21. The surface of the reflection wall 22 is coated with a paint having an excellent sound reflection effect. The axis from the center point of the open end 21 to the midpoint of the arcuate end 221 is the axis H where the major axis of the semi-ellipsoidal loudspeaker 20 is located. A bracket 25 is provided on the lower side of the reflection wall 22, that is, at a location close to the loading body 12. At the upper end of the bracket 25, a storage base 251 for holding the mobile phone 100 is provided. In the present embodiment, the storage base 251 includes a support surface 252 extending obliquely, and ribs 253 for holding the mobile phone 100 are provided on both sides of the support surface 252.

  As a modification, the storage table 251 may adopt a suction cup type that can attract the mobile phone 100. In addition, three claws may be provided on the storage base 251 and the mobile phone 100 may be sandwiched via the three claws. In this case, most parts of the mobile phone 100 can be exposed and the sound of the speaker of the mobile phone 100 can be maximized.

  When reproducing the audio of the mobile phone 100 using the reflective loudspeaker of the present invention, the mobile phone 100 is first set on the bracket 25. At this time, the speaker (sound generation point) is located at the end of the mobile phone 100. Next, when sound is emitted from the speaker, the sound is propagated to different parts of the reflecting wall 22 with the position of the speaker as a focal point, reflected by the reflecting wall 22 and propagated outward from the opening end 21 to one point. Collect (for example, point F shown in FIG. 3). In another embodiment, when the position of the speaker of the mobile phone 100 is slightly changed, the sound is collected at the points F1 or F2 shown in FIG. As described above, the volume and quality of the sound produced by the mobile phone 100 are improved by the reflective loudspeaker of the present invention. In the present embodiment, the storage table 251 provided with the ribs 253 is made of a sound transmissive material.

  Furthermore, the reflection type loudspeaker of the present invention is easy to carry because of its small volume. Moreover, since it can function as a speaker without being connected to a power source, energy can be saved.

  In addition, since the speaker of the mobile phone 100 is usually provided at both ends of the mobile phone or one end of the back surface, it is preferable that the speaker of the mobile phone 100 be positioned as close to the axis H as possible. Thereby, when the sound emitted from the mobile phone 100 is reflected by the reflecting wall 22, it is almost collected at the point F. That is, when the point F is located on the axis H, the sound effect of the mobile phone 100 is most excellent.
