Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention 2 relates to a car audio playback control device that systemizes optional products.

(Conventional Technology) As cars become more prevalent in daily life, the demand for car audio that provides a more comfortable time has increased, and there is a strong desire for something with high quality and sensitivity.

Here, car audio is a general term for an in-vehicle system that includes a tuner, tape deck, CD player, and other optional products, from a source playback source to speakers. Note that the source playback device section is generally called a car stereo.

By the way, as a recent trend in car stereos, combination car stereos have become mainstream instead of component car stereos. This is due to the development of electronic technology, which has made multifunctionality, high performance, and high density possible.

Here, the term "component car stereo" refers to one in which each part of a tape deck, CD player, tuner, amplifier, etc. is separated, and has a degree of freedom in combination. Furthermore, the term "funbiner stereo" refers to one in which a tape deck or CD player, a tuner, and/or an amplifier are integrated.

The tuner has changed from mechanical preset memory to a PLL tuner, and manual tuning has been replaced by a low-end tuner. Furthermore, cassette tape decks are now mostly logic-controlled and auto-reverse. There is a growing trend towards higher power amplifiers that can accommodate four speakers, and further electronicization and higher density are progressing.

(Problems to be Solved by the Invention) As described above, the conventional car audio system described above not only has a rich set of functions, but also has an increased degree of freedom in creating a system by combining obscene products. .

However, in recent years, CDs with much better sound quality than tapes have become popular, and with this, the need for magazine-type multi-CD players is increasing.

In this way, if the need for magazine-type multi-CD players increases, it would be a good idea to incorporate logic-controlled cassette tape decks, which are likely to be used relatively infrequently, into the system in terms of cost, etc. It will be disadvantageous.

In other words, motors dedicated to or shared with each other are required for inserting and ejecting the tape, moving the magnetic head toward and away from the tape, running the tape, and the like. Furthermore, since gears, cams, etc. are required to transmit the driving force from each motor, it goes without saying that the cost is high, and those that rely on logic ζ are susceptible to noise, moisture, etc.

For this reason, the adoption of a conventional mechanically controlled so-called anlogic mechanical deck is relatively advantageous in terms of cost, etc., and is considered to be sufficient to meet the needs of users.

However, even with an logic mechanical deck, there are advantages and disadvantages. In particular, the biasing force of a spring is generally used for inserting/ejecting the tape and for moving the magnetic head toward and away from the tape, and it is difficult to switch between each operation. Metallic sounds are sometimes generated, causing discomfort and hindering the quality of products.

In addition, regarding the operation of these systemized devices, since they are for in-vehicle use, the main focus is on safety while driving, so we aim to simplify and automate the operation of the mechanism as much as possible.
It is necessary to reduce the number of operations. Furthermore, in order to meet the needs of various users, there is a need for something with good operability.

The present invention was made in response to these circumstances, and
It is an object of the present invention to provide a car audio playback control device that can reduce costs when systemizing and improve operability.

(Means for Solving the Problem) In order to achieve the above object, the car audio playback control device of the present invention sequentially switches source inputs from a plurality of information playback means by a source switching operation of a source switching means. The control device includes a waiting time setting means for setting a waiting time required for the source switching means to switch to the next source, and a source switching operation by the source switching means continues within the waiting time set by the waiting time setting means. The present invention is characterized in that it includes reproduction control means for inputting a source by skipping over the current source in accordance with the number of source switching operations.

(Function) In the car audio playback control device of the present invention,
If source switching operations are performed consecutively by the playback control means within the set waiting time required for switching to the next source, the source is skipped by the number of operations, so source switching is facilitated. be able to.

(Example) Hereinafter, details of an example of the present invention will be described based on the drawings.

FIG. 1 shows a car audio according to an embodiment of the car audio playback control device of the present invention.

As shown in the figure, the car audio has a source switching button 1a, a mode setting key lb, etc.
It is comprised of a tape deck 4 of the gacha-mecha type described later, a multi-CD player 2 of the fli magazine type with a playback control device incorporating a tuner 5, and speakers 3, 3 for converting information from each source into sound.

FIG. 2 shows details of the reproduction control device rI11.

As shown in the figure, the playback control device @1 includes a CD drive unit 6 that causes the multi-CD player 2 to perform predetermined operations.
, a tape deck drive section 7 for causing the tape deck 4 to perform predetermined operations, and a tuner drive section 8 for causing the tuner 5 to perform predetermined operations. The playback control device fll also includes a memory 9 that stores playback procedures and set modes for each source, and mode settings that set playback modes in order according to the operating order of the source switching buttons 1a and the mode setting keys 1b. A section 10 is provided.

Furthermore, the playback control device [11 includes a waiting time setting section 11 that sets the waiting time required for switching to the next source using the source switching button 1a, and a waiting time setting section 11 that sets the waiting time required for switching to the next source using the source switching button 1a, and a waiting time setting section 11 that controls predetermined operations of each component based on information in the memory 9. Playback control unit 1 to control
2 are provided.

Next, the operation of the above-mentioned reproduction control device r111 will be explained using FIG. 3.

In the following flow, it is assumed that the source is switched in the order of multi-CD player 2 -> tape deck 4 -> tuner 5.

First, it is determined whether or not a switching operation has been performed using the source switching button 1a (step 301), and if the source at the time when the operation was performed is the multi-CD player 2 (step 302), the source input cut off (
Step 303).

Next, it is determined whether or not the waiting time required for switching to the next source using the source switching button 1a is set (step 3).
04), and if it has not been set, it is set (step 305), and then it is determined whether the waiting time has ended (step 305). Here, the waiting time required for switching to the next source is set to, for example, 0.5 seconds. In other words, the sources in this example are 3
This is because the operation of the source switching button 1a required for skipping source inputs only needs to be performed at least twice, and the number of operations required is within 0.5 seconds.

If there is no switching operation using the source switching button 1a within the waiting time of 0.5 seconds, the tape deck 4, which becomes the next source of the multi-CD player 2, is driven (step 307).

On the other hand, if the switching operation using the source switching button 1a is performed continuously within the waiting time of 0.5 seconds, (
In step 308), it is determined whether the source at that time is tuner 5 or not. If it is determined that it is the tuner 5, its driving is stopped, and then the multi-CD player 2, which becomes the next source, is activated (step 311).
) to be done.

However, (step 31O) assumes that the multi-CD player 2 is not included in the source, and if the multi-CD player 2 is not included in the source, the flow moves to (step 304). .

On the other hand, if it is determined in step 308 that the source at that time is not the tuner 5, the drive of the tape deck 4 is stopped (step 312), and the tuner 5, which will become the next source, is driven.

In this way, in this embodiment, the waiting time required for switching to the next source is set, and if source switching operations are performed consecutively within that time, the source is skipped by the number of source switching operations. , source switching can be easily performed.

In addition, since it is possible to switch the source by skipping, even if a Gachamecha type tape deck is included in the source, the metallic sound caused by the loading operation of the tape deck, which can be unpleasant if used infrequently, can be avoided. Prevented.

In this embodiment, a case has been described in which the present invention is applied to an in-vehicle car audio system, but the present invention is not limited to this example, and may be applied to other audio systems such as those for home use.

(Effects of the Invention) As explained above, according to the car audio playback control device r11ζ of the present invention, source switching can be easily performed by skipping operations, so that, for example, metallic sounds associated with loading operations are not generated. Since the source can include a gacha-mecha type tape deck that is rarely used, it is possible to reduce costs when systemizing the system and improve operability.
