Abstract

PURPOSE:To prevent the generation of the vibratory noise in panel parts and make clear the induction voice to be output by supporting a speaker box inside of a housing under the separated condition from the inner surface of the panel parts. CONSTITUTION:In an induction lamp 24, a speaker box 25 is fixed to side frames 29, 30 provided between the upper frame and the lower frame of a housing 26 to be supported in the housing 26 under the separated condition from voice panels 31, 32. Since sound pressure adjusting holes 33, 34 having an area half of an oscillating plate of a speaker unit 6 are formed in both surfaces of the speaker box 25, the voice is output from a sound pressure adjusting hole 33 through which the voice is output to the front of the unit 6, and the voice having the relative low sound pressure and to be output to the rear of the unit 6 resonates in the speaker box 25 to be output from the sound pressure adjusting hole 34 of the rear position. Consequently, the induction voice is output at the same sound pressure in outline in this induction lamp 24, and furthermore, since the speaker box 25 is separated from the voice panels 31, 32, the generation of the vibratory noise is eliminated to output the induction voice clearly.

Furthermore, according to the regulations, the guide light must be 9.9 m above the axis of the audio output section.
It is necessary to output the guidance sound with a sound pressure of 0 dB (A), but when the applicant measured the sound pressure at 1 m in front and back using a simulated sample of the above-mentioned guidance light 19.22, it was found that the sound pressure was approximately at the center of the housing 21. In the guide light 19 with the speaker unit 6 attached, the front is 90 dB (A), the rear is 80 dB (A),
In the guide light 22 where the sound path is formed by the cylindrical body 23, the front direction is 90 d.
B(A) and the rear was 85 dB(A). In other words, these guide lights 19 and 22 tend to have a difference in output sound pressure level in the front and rear directions, and it is difficult to output a guide sound having a specified sound pressure in both directions.

Effects of the Invention As described above, the present invention includes a box-shaped housing in which a display panel section having translucency on both sides and an audio panel section in which an audio emission hole is formed are arranged side by side, and A speaker box with a speaker unit attached from the inside is provided on one side of the sound pressure adjustment hole, and by supporting this speaker box inside the housing while being separated from the inner surface of the audio panel, vibrations of the speaker unit can be reduced. This prevents the sound from being transmitted to the audio panel section, display panel section, etc., and since no vibration noise is generated in these panel sections, the guided sound that is output is clear. Furthermore, each sound formed on both sides of the speaker box is By making the area of the pressure adjustment hole approximately half the area of the speaker unit's diaphragm, even one speaker unit can output audio with approximately the same sound pressure in both directions of the guide light, making it thin and lightweight with fewer parts. This has effects such as being able to obtain a high-performance guide light.
