Abstract

PROBLEM TO BE SOLVED: To solve the problem that it is desired to mount a passive radiator type speaker for reproducing bass because bass cannot be reproduced only by mounting one speaker in an acoustic space, however the passive radiator type speaker is expensive since only a driver consisting of a moving coil and a magnet is not attached and the other structure is the same as that of a waterproof speaker, thereby a bathroom television becomes considerably expensive.SOLUTION: Right and left acoustic spaces are air-tightly isolated with respect to a main space, openings which are open forwards are formed in both the acoustic spaces, and both the acoustic spaces are made into bass reflex speaker box. Speaker cords connected to an audio signal output section is drawn out through a wiring opening formed on a back of the main space, and the speaker cord is connected through either of the openings formed on backs of both the right and left acoustic spaces to a waterproof speaker.

Description

  The present invention relates to a bathroom television equipped with a liquid crystal display unit attached to a wall surface of a bathroom.

  Conventionally, in order to watch television broadcasts while taking a bath, many television devices installed in the bathroom have been proposed. In recent years, a so-called liquid crystal bathroom television provided with a liquid crystal image display unit for displaying an image has been proposed. Since the liquid crystal bathroom TV can reduce the thickness of the TV main body, it can be directly attached to the wall surface of the bathroom without constructing a window hole or the like on the wall surface of the bathroom.

  Even in the case of a liquid crystal bathroom TV, it is necessary to connect a cord and various wires from the power source. Therefore, an opening is provided on the back of the casing of the bathroom TV, and these cords and wires are drawn out from the opening, A wiring hole facing this opening is formed on the wall where the TV is installed, and the cord and wiring are drawn out of the bathroom through the hole.

  In addition, there is known one in which waterproof speakers are attached to the left and right with a liquid crystal display unit interposed therebetween so that TV sound can be reproduced in stereo (for example, see Patent Document 1).

JP 2008-219447 A (FIG. 2)

  In a liquid crystal bathroom television, even if a small amount of hot water enters the casing, the humidity in the casing rises, causing condensation on the inside of the transparent plate that covers the front surface of the liquid crystal display unit and clouding. Then, since trouble occurs in viewing the television screen, the casing is configured so that hot water does not enter from the outside.

  On the other hand, as described above, since the liquid crystal bathroom television is thin, only a small waterproof speaker can be attached. For this reason, the low frequency component of the reproduced sound is insufficient, and it is difficult to produce a sound with a profound feeling. Therefore, the liquid crystal display unit and the audio signal output unit are housed in the main space in the center of the casing, and acoustic spaces are provided on the left and right sides of the main space so that the acoustic space functions as a speaker box. However, the audio signal output unit and the waterproof speaker need to be connected by a speaker cord, and a hole for passing the speaker cord must be provided so as to communicate the main space and the acoustic space. Must remain airtight. For this reason, since only one speaker is attached to the acoustic space, the low frequency component is insufficient. Therefore, it is desirable to attach a drone cone in addition to the waterproof speaker in order to reproduce the low frequency component.

  However, the drone cone is not attached with a drive unit consisting of a moving coil and a magnet, and the other structure is the same as a waterproof speaker, so the price is high, so that the price of the bathroom TV rises. .

  In view of the above problems, an object of the present invention is to provide a liquid crystal bathroom television that can reproduce low-frequency components at low cost.

  In order to solve the above problems, a bathroom television according to the present invention is provided with an interior space of a watertight casing fixed to a bathroom wall, a main space for housing a liquid crystal display unit and an audio signal output unit, and a waterproof speaker. In a bathroom television divided into an acoustic space, the acoustic space is hermetically isolated from the main space, and an opening that opens forward in the acoustic space is formed to make the acoustic space a bass-reflex speaker box, and The speaker cord connected to the audio signal output unit is pulled out through the wiring opening formed on the back surface of the main space, and the speaker cord is connected to the waterproof speaker through the opening formed on the back surface of the acoustic space. To do.

  Instead of using a drone cone as in the prior art, the acoustic space is reduced to a bass reflex type speaker box. However, if the bass-reflex type is used, an opening that opens the acoustic space to the outside must be formed, and if hot water enters the acoustic space from the opening, the conventional one passes through the hole that was formed to pass the speaker cord. Moisture enters the main space. Therefore, the speaker cord is wired through the outside of the casing without providing such a conventional hole.

  As is apparent from the above description, the present invention can increase the reproduction of low-frequency components while blocking the intrusion of hot water into the main space in the same manner as in the past, and can watch TV with a profound sound. .

Front view of bathroom TV with one speaker cover removed The figure which shows the shape of the rib of a rear case The figure which shows the wiring state of the speaker cord in the back

  Referring to FIG. 1, reference numeral 1 denotes a bathroom television according to the present invention. A liquid crystal display unit 12 for displaying a television image is disposed at the center in the left-right direction. Note that the front surface of the liquid crystal display unit 12 is sealed with a transparent plate so that the liquid crystal display unit 12 is not directly exposed to hot water.

  Speaker covers 11 are detachably attached to the left and right sides of the liquid crystal display unit 12. In the figure, the left speaker cover is removed. When the speaker cover 11 is removed, the front case 2 constituting the casing is exposed. The casing is formed such that the front case 2 and the rear case 4 shown in FIG. The casing is divided into three spaces by a pair of left and right ribs 41 of the rear case 4. The liquid crystal display unit 12 is stored in a main space located in the center in the left-right direction, and an audio signal output unit (not shown) is also stored in the main space. An acoustic space is formed on both sides of the main space, and one waterproof speaker 3 is installed in each acoustic space.

  The main space and the two acoustic spaces are hermetically isolated by the rib 41, and hot water and water vapor do not enter at least from the acoustic space side into the main space.

  The front case 2 has an opening 31 located below the waterproof speaker 3. Therefore, the acoustic space communicates with the outside through the opening 31. This opening 31 is for making the acoustic space into a bass-reflex type speaker box, and the sound in the high to mid range is sounded directly forward from the waterproof speaker 3, but the sound in the low range passes through the acoustic space. The sound is amplified by resonance or the like, and sounded forward from the opening 31.

  With reference to FIG. 2, a hole 44 is provided in the center of a position 42 where the waterproof speaker 3 is attached so that a speaker cord, which will be described later, can be passed therethrough. In addition, an opening 43 is formed for supplying power to various devices housed in the main space and for passing codes for carrying other broadcast signals.

  Referring to FIG. 3, since the audio signal output unit is housed in the main space as described above, the speaker cord 5 connected to the audio signal output unit is once pulled out from the opening 43, and the extracted tip Was inserted into the acoustic space through the hole 44 and the tip thereof was connected to the waterproof speaker 3. Since it comprised in this way, even if hot water penetrate | invades in acoustic space and the water vapor | steam leaks out from the hole 44 to the back surface of the bathroom television 1, when the bathroom television 1 is attached to the wall surface of a bathroom, Water vapor or the like leaking from the hole 44 is blocked without reaching the opening 43 by the packing sandwiched between the wall surfaces.

  In addition, this invention is not limited to an above-described form, You may add a various change in the range which does not deviate from the summary of this invention. For example, in the above embodiment, the acoustic space is provided on the left and right sides of the main space so that stereo sound can be reproduced. Can do.
