Making and installing an acoustic shelf in a Lada Priora with your own hands

Well, it's time to tell everything in order.

Three days ago I decided to make an acoustic shelf for a Prioric Hatch. One large chipboard and one large sheet of plywood for the shelf itself, as well as several smaller boards for the sides.

Started work. I removed the shelf and the side panels (the latter are held on by 4 screws - 2 on the trunk lid side, 1 in the center of the side panel and 1 on the seat side).

I drew out the left side panel, started cutting it out, took a long time and painfully to adjust everything to size, but... I’ve never seen wooden shelves before, obviously nothing worked out for me, I couldn’t figure out how to put it in its regular place.

As a result, the day went down the drain.

The next day I went to a friend to get patterns for the sides and shelves. He offered to help with the production, I couldn’t refuse, because... I was sure that I couldn’t cope on my own.

I went to the store and bought everything I needed, namely, several packages of self-tapping screws of different lengths with wide heads, a piano hinge, carpet - 1.5 m, mounting glue for wood, metal hangers (using them in the future we will secure parts of the side panels between each other and install them in their normal place.)

Then the procedure began for drawing the sides according to the pattern and then sawing them out.

After all the parts of the side panels were cut out, they were fastened with self-tapping screws, and the “hump” was screwed to the main part of the side panel using metal hangers.

We tried on the first side panel - it fit like a original, there were small gaps in some places - just under the carpet)

Then they cut out the second one and repeated the steps.

The next day we tried to fit the speakers into the side panels, as usual - from above, it turned out that we were a little wrong with the size of the holes for the speakers, but it was not scary, we just covered the holes with a secret mesh)) and covered them with carpet on top, and seated the column from below. How they covered it with carpet - glue was purchased for installation, and a construction stapler was also borrowed. The upper part of the side panel was coated with glue and a carpet was applied, then with a little effort the edges were tightened and stapled from below.

And voila - we got amazing sidewalls, just like straight from the factory)

Purpose of the acoustic shelf

This part serves to secure the sound speakers of the music system. It is carried out in such a form that the size and shape ensure the greatest purity and volume of the sound of the installed speakers.

Materials for making an acoustic shelf

In the practice of manufacturing this part, only two types of materials are usually used:

1. Wood, usually plywood.
2. Plastic base.

Each of them has its own advantages. Thus, the wood is softer and is better for applying decorative coatings. After all, they try to cover the shelf with beautiful fabric to match the color of the upholstery. And, of course, attaching fabric to plywood is much easier than to plastic, without gluing. However, the plastic is not damaged by moisture and does not delaminate like plywood. So you need to choose the material for the acoustic shelf wisely. And take into account all the conditions in which the Priora is operated.

What shape are Priora acoustic shelves made of?

These parts are made according to the shape of the space between the rear seat and the body under the glass. The best option is to take measurements from the standard shelf, and having made the appropriate layout, use it to make your own version, with recesses for the available speakers.

Selection of material for construction

It is recommended to choose natural wood for the manufacture of parts. The wood is pre-treated with special moisture-resistant compounds that improve the quality of the material.

And for finishing the base, materials are chosen based on the effective appearance of the product. For example, to achieve solidity, the structure is decorated with leather or its substitute (a cheaper option). Some people like suede, velvet, thick brocade. But, you should understand that fabric surfaces will collect a lot of dust. They are more difficult to clean and fade over time. While leather is quite easy to clean and lasts longer.

Refinement of the factory version of the acoustic shelf

Of course, it is not always possible to invest, or simply not everyone has the ability to work with wood. But don't be upset. After all, it is quite possible to carry out minor modifications to a part installed at the factory. And although this is not the option of installing a shelf yourself, however, such a modification will significantly improve the sound. And you just need to treat the seats with regular foam and put a layer on the entire lower part of the part. This will allow you to secure the soundbar tightly enough and almost completely avoid vibration. This is, so to speak, a budget option.

For hatchback and station wagon

There is no particular difference between them in the manufacturing process. You just need to remember that on a station wagon body, the shelf rises when the rear door is opened, and therefore a more careful adjustment is needed. Well, it is advisable to make it heavier, for a confident landing in place.

Owners of domestic cars are trying to improve existing models. The most common type of tuning is the installation of a modern speaker system. For these purposes, the rear acoustic shelf of the Priora Hatchback is installed. You can either purchase such a shelf at a car dealership or make it yourself.

Fixing the rib in the exhalation position like a “pump handle”

This dysfunction is characterized by fixation of the rib in a lowered position, which corresponds to its movement during the exhalation phase. In this state, the rib freely exhales, but cannot fully inhale.

This technique is performed for the 3rd-6th ribs. The goal is to restore the bucket handle component of the movement that is stuck in the rib exhale position.

Patient position: supine. The arm on the side of the affected rib is bent so that the wrist is in contact with the forehead.

Position of the osteopathic doctor: standing next to the patient on the side opposite the affected rib.

Position of the osteopathic doctor's hands: the doctor takes the patient's elbow and wrist with the forearm of one hand. With the bent fingers of the other hand, grab the affected rib by the back with a “hook”.

Correction:

1. The osteopathic doctor induces rotation of the patient's head in the direction opposite to the affected rib by 15-45° (the lower the rib is, the greater the rotation).
2. The doctor asks the patient to take a breath. While inhaling, raise the elbow and head up, as if the patient wants to sit against resistance, for 3 seconds, creating a state of tension.
3. After 3 seconds, the doctor asks the patient to exhale and relax. In this case, as you exhale, the doctor pulls the posterior arch of the rib downwards and laterally, increasing the rotation of the head from the rib and abduction of the elbow.
4. The entire cycle is repeated three times.

Buy or make it yourself?

The installation of acoustics affects the entire interior of the car. Thus, it can be supplemented with decorative elements or changed completely. Installing speaker systems yourself allows you to:

• Take into account the dimensions of the trunk and column (the holes for the columns must correspond to their diameter).
• Select the speaker connection scheme and the ability to change playback modes.
• Select upholstery, decorative elements, color and texture (natural and artificial leather are ideal for upholstery).
• Possibility to save internal space (the size of the structure may be non-standard).
• Choose the main material, it is better if it is wood (chipboard, MDF, plywood).

Chest and ribs

Osteopath: techniques on the ribs

Main functions of the chest:

1). Protects vital organs (heart, lungs) - this is “armor”.

2). Plays an important role in respiration (aeration).

3). Ensures blood flow (through the creation of negative pressure).

4). Affects fluid circulation (cerebrospinal fluid, lymph, venous blood).

Each rib contacts:

1). The bodies of adjacent (overlying and underlying) vertebrae (except Th1 and Th12);

2). Intervertebral disc (via a ligament from the crest of the head for ribs II-X);

3). Transverse process of the vertebra (except XI and XII);

4). Sternum (through cartilage) – ribs I-VII;

5). Above and below the ribs (via the intercostal muscles);

6). Parietal pleura.

The main structure of the chest is the ribs. They are typical and atypical (see table below).

Characteristics of atypical ribs

Costochondral junction:

1). The anterior end of the rib is a cone that fits into the cartilage cavity.

2). At this level, the movements of the ribs in three planes of space are absorbed by the cartilage.

A cone also forms at the sternocartilaginous level.

Note: normally, if a rib rises, the sternum rises along with it. The rib in front transmits its movement to the sternum.

Manufacturing process

Such car accessories should be made very carefully. Working out the smallest details. The Priora Hatchback acoustic shelf is made exclusively from a pre-made stencil. Creation sequence:

What happens in the end?

The rear shelf on the Priora, created with your own hands, will not be inferior in quality or appearance to standard models, which are sold in a wide range in any online store. In addition, creating a shelf for your own design from professionals or ordering it from an online store will cost you much more than you will assemble the option you like in your garage. The most important thing is that before starting work, be sure to read the photographs of the manufacture and installation of the shelf on the Priora.

Remaking a standard acoustic shelf

The Priora Hatchback acoustic shelf is perfect for modification, and it is several times cheaper than creating a new one. This will only require additional strengthening of the base of the standard spare part. To do this, you can use polyurethane foam in a can. Remodeling stages:

Also, a standard acoustic shelf can be decorated and supplemented with various decor, allowing for changing the upholstery or installing additional accessories.

Rib compression

Compression is characterized by compression of the rib in the ventrodorsal direction. This can occur from microtraumas, with constant work loads on the sternum and ribs. As a result, the rib becomes shorter in the ventrodorsal direction and wider in the lateral direction.

Diagnostics: ventral displacement of the posterior angle of the rib - upon palpation, a “pit” is determined at the site of the rib angle; dorsal drowning of the anterior end of the rib - a depression is palpated at the junction of the bony part of the rib with the cartilaginous part; Laterally, along the axillary lines, the protrusion of the rib - the tubercle - is palpated. This dysfunction is possible on the 3rd-6th ribs.

Right rib compression

Result

As a result of independent production, you get exactly the same or a completely original rear acoustic shelf of the Priora Hatchback, not much different from the assortment in the store. In addition, making it yourself will, oddly enough, be faster and cheaper. You don’t have to wait for your order to be delivered, and the upholstery fabric can be selected at the right price and quality.

The main thing in this process is to study the specifics of the acoustic system, calculate the dimensions of the future shelf and then boldly take up the instrument.

It will be difficult for a non-professional to decide how to choose the size and material to obtain the most comfortable sound production. But if you want, it’s quite possible to find diagrams and instructions for any type of acoustics and car.

Anatomical features of the ribs

Anatomical features of the structure of the chest

There is nothing complicated in the anatomy of the human ribs; it is a simpler element than the spine or small bones of the feet and hands. The ribs have a curved design, they are quite long, and consist of bones and cartilage. The thickness of the bone elements reaches 5 mm. There are a total of 12 pairs of ribs connected in the chest. They differ in names, sizes, and are not even always the only elements in this system.

The numbering of a person’s ribs starts from top to bottom; the closer to the pelvic area, the softer and thinner these bones become. The 10th rib in humans is located just below the xiphoid process, and the 1st is located near the collarbone. The plate of these bones contains 3 main elements: the head, the body and the neck. With the help of the head and neck, the rib is attached to the spine. They provide articular connection. The body of the first 7 pairs gradually turns into cartilaginous tissue and connects to the chest. The main feature of this growth from bone to cartilage is the high mobility of the joint.

Other features of the costal system include:

• the first, most powerful 7 pairs are called true, and 8, 9 and 10 are called false ribs, since they are connected to each other by cartilaginous plates;
• The 11th and 12th pairs are movable, or free ribs, which got their name due to their maximum mobility; they are attached only to the spine;
• the upper part of the bone tissue is rounded, and the lower part is sharp;
• Nerve fibers and blood vessels pass through the groove on the lower, reverse side.

Review of popular shelves on Priora

Priora station wagon acoustic shelf

Let's look at the most popular shelves sold today in stores in our country. First, let’s find out what technical characteristics stand out for the shelves on the Priora that have sidewalls.

It is clear that the main advantage of a shelf with sides is the location of the speakers (see How to choose speakers for a car radio on your own). They do not stand on the main plywood, but on the side parts. This provides a unique opportunity to conveniently load cargo into the trunk for transportation. Now you won’t have to remove the shelf with the speakers every time. In addition, it is possible to select the desired color of the polo, depending on individual preferences and matching the interior color.
