Description

[Detailed Description of the Invention] This invention relates to a vertical audio device in which a record player having a vertically erected turntable and other audio devices are integrated.

2. Description of the Related Art Conventionally, a record player with a built-in audio device such as a stereo or as a stand-alone record player is usually configured with a turntable installed horizontally.

However, in such a horizontal record player, the front and rear (depth) dimensions require at least the turntable diameter, for example, 30 cm, which limits the installation space.
In addition, there are limits to the design, and it is currently impossible to create unique designs while maintaining the horizontal design.

Therefore, as shown in FIGS. 1a and 1b, a vertical record player in which a turntable is installed vertically or an audio device having this record player may be considered.

In Figures 1a and b, 1 is a record player, 2
3 is a turntable, 3 is a record clamper, 4 is a clamper arm, 5 is a tone arm, 6 is a cartridge, 7 is a record stylus, and 8 is a weight for adjusting stylus pressure.

In this case, the weight 8 can be moved in and out in the left and right (double arrow) directions, for example in FIG. 1, and adjusts the stylus pressure by increasing or decreasing the load in the direction of the single arrow.

9 is the flywheel, here mainly turntable 2
This is provided to balance the weight of the turntable 2 and correct the inclination of the spindle of the turntable 2.

10 is a touch button for controlling the player, 11 is a rubber cushion, and 12 is a record disc.

In this figure, details of drive mechanisms such as the turntable 2 or the tone arm 5 are not shown.

With this vertical shape, the longitudinal (depth) dimensions of the device can be arbitrarily set without being restricted by the turntable diameter, and a thin device smaller than the turntable diameter can therefore be realized.

Also, in terms of design, the turntable 2 faces straight ahead, which is completely different from the conventional design, and it is possible to create an unusual design.

As an example of a vertical audio device having the above-mentioned record player, the configurations shown in FIGS. 2a and 2b can be considered.

In Figures 2a and b, A is a record player storage area, B is a tuner, amplifier and tape deck storage area,
C is a cassette tape case storage part, D is a record disc storage part, L is a frame body, here is a rack, and La is a rack leg part.

In other words, the tuner, amplifier, chip, etc. are stacked vertically with the record player in a single rack L.
It has been incorporated into.

However, in such a vertical audio device, the height is high relative to the bottom area of the device, so the center of gravity tends to be located upward.

In particular, as shown in FIGS. 2a and 2b, if a large number of audio devices are arranged vertically in series and a record player is placed above, the center of gravity tends to be located upward.

For this reason, the device tends to be tilted forward, but even if there is no risk of the device tipping forward, the following disadvantages occur especially in the case of a vertical audio device.

That is, in the case of the vertical record player 1 shown in FIGS. 1a and 1b, gravity acts on the tone arm 5 so that it always faces straight down.

For this reason, in order to apply stylus pressure to the record 12 when playing a record, a weight 8 is provided so as to apply a load to the side of the record 12.

However, when the device is tilted forward, the force directed directly below the tone arm 5 becomes greater than the load exerted by the weight 8' on the side of the record 12 in the direction of the single arrow in the figure.
The record stylus 7 cannot reach the tone groove of the record 12, making it impossible to trace and therefore unable to play.

For this reason, in this type of vertical audio device, even a slight forward tilt must be avoided, and improvements in this respect have heretofore been desired.

This idea was made in view of the above requests.
To provide a vertical audio device which prevents the device from tilting forward and prevents the inability to play records.

An embodiment of this invention will be described below with reference to FIGS. 3 to 5.

FIG. 3 is a side view showing the main parts of an embodiment of the vertical audio device according to this invention. FIG.

In this figure 3, 13 is a tuner, 14 is an amplifier,
15 is a tape deck.

In addition, 16 is a tuning knob, 17 is a flywheel, 18 is an AM/FM selector board, 19 is a tuning guide,
20 is a pulley, 21 is a wheel, 22 is a wheel support member, 23 is a bar antenna, 24 is a tuner board, 25 is an antenna terminal, 26 is a volume knob, 27 is a tone control knob, 28 is a volume, 29 is a hono, Tuner board, legs of tape deck or record player selection switch (not shown), 30 is the selector board, 31 is a relay, 32 is a power amplifier board, 33 is a power amplifier IC 134, its heat sink, 35 is an IC leg,
36 is a preamplifier board, and 37 is an equalizer board.

Furthermore, 38 is a power supply board, 39 is a power transformer, 40 is a capacitor, 41 is a tape deck, 42 is an operation button,
43 is a cassette tape case part, 44 is a tape deck mechanism part, 45 is a flywheel, 46 is a motor, 4
7 is a mounting plate for these, 48 is a tape deck circuit printed board, 49 is a link mechanism, and 50 is a mounting plate for these.

In FIG. 3, the left side shows the front side of the device, and the right side shows the rear side of the device.

In other words, this invention is based on the case where all three audio devices (tuner 13, amplifier 14, and tape deck 15 as shown in FIG. 3) are added to the record player 1. Install the additional audio equipment (tuner 13, amplifier 14) so that the overall center of gravity of the additional audio equipment (audio equipment) is located at the center in the front-rear direction of the device (hereinafter referred to as the rack center) or on the rear side of the center.
, the components of the tape deck 15) are arranged.

In the embodiment described above, this is achieved by disposing the power transformer 39, heat sink 34, etc. on the rear side, as shown in FIG.

FIG. 4 is a side view for briefly explaining an example of the above-mentioned device, and as shown in the figure, the device includes audio equipment added to the record player 1, including a tuner 13, an amplifier 14, and a tape deck. (G
B>GF) is set.

Therefore, according to this invention, the power transformer 39 and the heat sink 34 of the additional audio equipment, which are heavy, are arranged on the rear side rather than the center in the front-rear direction of the device, so that the overall center of gravity of all the audio equipment including the record player 1 is It can be positioned at the center of the rack or on the rear side of the center, or can be operated so as to be positioned, and has the effect of preventing the device from tilting forward and, by extension, from being unable to play records.

In the above-mentioned embodiment, the record player and the audio equipment attached thereto are installed vertically in a series in a common frame. Needless to say, this idea can also be applied when incorporated into the body.

FIGS. 5a and 5b are diagrams showing an example in which a record player and the above-mentioned additional audio equipment are integrated on the left and right sides.

In this figure, parts equivalent to those in FIGS. 2a and 2b are given the same reference numerals.

Further, in the above embodiment, as can be seen from FIGS. 1A and 1B, a linear tracking arm is used as an example, but it goes without saying that a normal arm that rotates around the support point of the tone arm 5 can also be used.
