Abstract

PURPOSE:To improve the quality of received voice and sound pressure by arranging a speaker in a case so that a reproduced voice is radiated in the upper direction, providing a reflecting plate in the case and forming an opening through which a voice reflecting in the reflecting plate radiates to the outside of the case to the side wall of the case. CONSTITUTION:A speaker 9 is fitted to the side wall inner face of a placing case 8 via a packing 14 so that a reproduced sound radiates in the upper direction. An acoustic reflecting plate 15 whose cross section is an inverted triangle is formed to the upper wall in the placing case 8 so as to reflect the sound radiating in the upper direction from the speaker 9 in the forward/backward direction. Moreover, plural sound holes 10 radiating the sound reflected in the acoustic reflecting plate 15 externally are formed to the side wall before and after the placing case 8. Thus, the sound quality and sound pressure of the received voice are improved and the practical arranging position is not limited.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a telephone stand with a built-in speaker.

2. Description of the Related Art In general, this type of telephone stand has a built-in speaker for making calls (hands-free calls) without holding the telephone in hand.

FIG. 2 shows the configuration of a conventional telephone stand.

In FIG. 2, reference numeral 1 denotes a stand case on which the telephone main body 6 is placed on top of it, and a speaker is installed on the inner surface of the upper wall of the stand case 1 so that the reproduced sound is radiated upward. 2 is attached via a packing 3, and a plurality of sound holes 3 are formed in the upper wall of the speaker 2 to emit the sound reproduced by the speaker 2 to the outside.

The stand case 1 has holding parts 6 and 7 for holding the phone main body 6 so that it does not fall out of its position when it is placed.
The holding parts 6 and 7 are formed such that the telephone main body 6 is placed on the sound hole 3 due to the dimensions of the stand case 1 and the telephone main body 6.

In the above configuration, when making a hands-free call, etc., the received sound played by the speaker 2 is emitted to the outside through the sound hole 3 of the stand case 1, and the sound is emitted to the outside through the sound hole 3 of the stand case 1, and released into free space from between.

Problems to be Solved by the Invention However, in the above conventional telephone stand, due to the dimensions of the stand case 1 and the telephone main body 6, the telephone body 3 is placed on the sound hole 3 of the speaker 2, so the speaker There is a problem in that the sound reproduced by the telephone 2 is blocked or scattered by the telephone main body 5, resulting in a significant deterioration of sound quality and sound pressure.

In particular, this problem becomes more pronounced in recent years because the outer shape of the telephone main body 5 is designed to have a curved surface that scatters sound.

In order to solve the above problem, the speaker 2 may be placed laterally, but in this case, the practical placement positions of the stand case 1 and the phone main body 5 may be limited, or the speaker 2 may not be able to receive signals in multiple directions. There is a problem in that multiple speakers are required to emit sound.

SUMMARY OF THE INVENTION In view of the above conventional problems, an object of the present invention is to provide a telephone stand that can improve the sound quality and sound pressure of received audio, and that does not limit the practical placement position even when one speaker is used. do.

Means for Solving the Problems In order to achieve the above object, the present invention arranges a speaker in a case so that the reproduced sound is radiated upward, and uses a reflection system to horizontally reflect the sound emitted by the speaker. A plate is provided inside the case, and an opening is formed in the side wall of the case to allow the sound reflected by the reflector to be released outside the case.

According to the present invention, with the above configuration, the received sound is emitted in the horizontal direction, so the sound emitted by the speaker is not blocked or scattered by the telephone body, and therefore the sound quality and sound pressure of the received sound are improved. In addition, the practical placement position is not limited.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1st
FIG. 1(a) is a front view showing an embodiment of the telephone stand according to the present invention, and FIG. 1(b) is a side view taken along line AA in FIG. 1(a).

In FIG. 1, reference numeral 8 denotes a stand case on which the telephone main body 11 is placed, and a speaker 9 is provided on the inner surface of the side wall of the stand case 8 so that the reproduced sound is radiated upward and the sound is 5A. is attached via a packing 14. The telephone main body 11 has a built-in transmitter (not shown) on the left side of FIG. 1(a), and a built-in receiver (not shown) on the right side.

An acoustic reflecting plate 15 having an inverted triangular cross section is formed on the upper wall of the stand case 8 in order to reflect the sound emitted upward by the speaker 9 in the front and back direction.
A plurality of sound holes 1Q are formed in the front and rear side walls of the sound hole 1Q for emitting sound reflected by the sound reflection plate 15 to the outside.

Incidentally, the stand case 8 is formed with holding parts 12 and 13 for holding the telephone main body 11 so that it does not come off the position when it is placed.

Generally, the stand case 8 and the telephone main body 11 are arranged so that the transmitter and receiver are on the left and right sides, respectively, as shown in FIG. It can be placed in any direction depending on the location.

In the above configuration, when making a hands-free call or the like, the received sound reproduced by the speaker 9 is first radiated upward, and then the sound reflecting plate 15 is radiated upward as shown by the arrow in the figure.
The sound is reflected back and forth by the sound hole 1o of the stand case 8.
is released to the outside via the

In this case, the received voice reproduced by the speaker is not blocked or scattered by the telephone main body 11 as in the conventional example, and therefore the sound quality is not deteriorated.

Furthermore, as shown in FIG. 1(a), the stand case 8 and the telephone main body 11 are arranged so that the transmitter and receiver are on the left and right sides, respectively, or when they are arranged in the opposite direction. Furthermore, since the received sound is emitted in the direction of the user, the sound quality does not deteriorate.

Furthermore, even if the telephone is arranged so that the received voice is emitted to the left and right as shown in FIG.
Since the sound is not blocked or scattered, the sound quality does not deteriorate.

In the above embodiment, the acoustic reflection plate 16 has an inverted triangular cross section.
By forming a sound hole 1o in the front and rear side walls of the mounting case 80, the sound emitted upward by the speaker 9 is reflected in the front and back direction. However, by forming an inverted cone-shaped reflector instead, the speaker 9
The sound radiated upward is reflected in all directions on the horizontal plane, and by forming the sound holes 10 on the front, rear, left, and right side walls of the stand case 80, the sound reflected by the acoustic reflector is emitted externally in the front, rear, left, and right directions. If configured to do so, good sound quality can be achieved no matter which direction the stand case 8 and the telephone main body 11 are placed.

Effects of the Invention As explained above, the present invention has a speaker arranged in a case so that the reproduced sound is radiated upward, and a reflector plate that reflects the sound emitted by the speaker horizontally in the case. In addition, an opening is formed in the side wall of the case to allow the sound reflected by the reflector to be released outside the case, so the received sound is emitted horizontally, and the sound emitted by the speaker is blocked by the phone body. Therefore, the sound quality and sound pressure of the received sound can be improved, and the placement position is not limited in practical use.
