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 equipment 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, such a horizontal type record player requires at least the turntable diameter (for example, 30 cm) in its front and rear (depth) dimensions, which limits the installation space and has design limitations as well. At present, it is not possible to create elaborate designs.

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
It is provided to balance the weight of the turntable 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 omitted from illustration.

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 record player described above, 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.

That is, a tuner, an amplifier, a tape deck, etc. are stacked vertically with a record player and assembled into one rack L.

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 the record player is placed above, the center of gravity tends to be located upward.

For this reason, the device tends to be in a forward-leaning position, but even if there is no risk that the device will fall over if it is tilted forward, the following disadvantages occur particularly in the case of vertical audio equipment.

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 applied by the weight 8 toward the record 12 side in the direction of the single arrow in the figure, and the record stylus 7 It is impossible to reach the 12th tone groove, making it impossible to trace and therefore impossible 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 chibutsu mechanism part, 45 is a flywheel, 46 is a motor,
47 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 shows 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, so these three Install the additional audio equipment (tuner 13, amplifier 14) so that the overall center of gravity of the audio equipment is located at the center in the front and back 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.

At the same time, in this invention, the components of the record player 1 are arranged so that the center of gravity of the record player 1 as shown in FIGS. 1a and 1b is located at the center of the rack or on the rear side of the center.

This is achieved, for example, by arranging the flywheel 9, player drive motor, etc. as close to the rear side as possible.

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. 15 The weight GB□ of the center of the entire rack (indicated by the dashed line in the figure) or the rear half of the center is greater than the weight GF1 of the front half.
(GB□>GFI) and the weight GB□ of the rack center of record player 1 or the rear half of the center
The front half weight is thicker than GF□ (GB□>GF2
) is set.

Therefore, according to this invention, the flywheel 9 connected to the back side of the turntable 2 of the record player 1, the power transformer 39 of the additional audio equipment, and the heat sink 34 are arranged on the rear side of the device from the center in the front-rear direction. Since the center of gravity of the record player 1 and the overall center of gravity of the additional audio equipment are located at the center in the front-rear direction of the device or on the rear side, the center of gravity of the record player 1 and the overall center of gravity of the additional audio equipment is located at the center or the center of the rack. This has the effect of preventing the device from tilting forward, which in turn prevents the player from being able to play records.

In addition, in the above embodiment, the record player and the audio equipment attached to it are installed in a common frame in the vertical direction, but the record player and the audio equipment attached to it are installed in a common frame on the left and right sides. It goes without saying that this idea can also be applied when incorporated into a.

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.
