In recent years, a very convenient option has gained great popularity - a speakerphone in a car for a phone. Thanks to this system, it is possible to synchronize a mobile phone with the car's multimedia system, so that it is possible to have a conversation using the car's regular speakers in hands-free mode.
What are the advantages and disadvantages of such a system and is it possible to manufacture it yourself on machines in which it is absent - we will talk about all this in this article.
The history of the appearance of a speakerphone in a car for talking on the phone
The reason for the appearance of hands-free systems for the car was, of course, the tightening of legislation regarding the use of mobile telephones while driving a car.
The fact is that the legislation of most countries of the world prohibits the use of a mobile phone while driving a car, allowing only a conversation using Hands Free systems without the use of hands. It is for this reason that the engineers had the idea to integrate telephone functions into a multimedia system.
Technically, such a refinement looked very simple. Indeed, the car audio system includes the main component - speakers capable of reproducing sound. Embedding a microphone and interfacing with a phone is a matter of minor technical and software integration, and the benefits of the option turn out to be quite a lot.
The first hands-free systems in the car were synchronized with the telephone via a wire through the radio. Later, with the development of wireless technologies for voice and data transmission via the Bluetooth protocol, multimedia systems began to use this wireless channel for synchronization, and the appearance of modern displays in radio tape recorders made it possible to use them not only for transmitting voice data, but also for reading text messages received on a mobile phone. driver phone.

Today, systems for integrating smartphones and on-board multimedia are highly developed. The car's audio system is capable of supporting the full range of functions of a modern mobile phone, including voice communication, Internet access, use of Internet messengers, etc. In this case, in the event of an incoming call, the sound of the audio system is automatically muted, but after it ends, music playback resumes.
Speakerphone in the car through the radio with your own hands
Of course, the speakerphone system in the car is a very convenient thing. However, this option is not provided in all cars, at least in the standard version. At the same time, dealers very often offer this option for a surcharge, which can be from 20 thousand rubles or more. It goes without saying that such an overpayment often turns out to be unprofitable, and many car owners deliberately refuse additional costs.
However, in fact, you can organize a speakerphone in a car for a phone with your own hands at minimal cost. So, let's see what opportunities exist for organizing hands-free communication in a car on our own.
Perhaps the simplest from the point of view of technical organization is the wired connection of a mobile phone with a radio. You can organize it very easily, provided that your car radio is equipped with an AUX connector. In fact, this connector is a traditional 3.5 mm headphone output for the appropriate plug, familiar to all owners of audio players, and mobile phones as well.
Nowadays, almost all cell phones have the same connector for connecting a wired headset or regular headphones. So, if the radio of your car is equipped with such an output, and it is also present on the mobile phone, then we can assume that the problem has been solved.
All that is required to organize a speakerphone in a car through a radio tape recorder with your own hands is to purchase a jack-to-jack wire with a pair of 3.5 mm jacks, the same as used in headphones. Similar wires can be found in almost any electronics store.
By connecting the phone and the radio using such a wire, we get a working speakerphone system. Its only drawback will be that to answer the call you will need to press the button directly on the telephone, and the telephone itself will be connected by a wire to the radio. In addition, during a conversation, the microphone located inside the phone will be used, and therefore the audibility for the interlocutor may deteriorate.
Much more difficult if the radio is not equipped with the appropriate connector. In principle, at this stage, many motorists can abandon the idea of \u200b\u200borganizing a speakerphone, however, with some skills in working with electronics and knowledge of circuitry, you can try to make the system yourself using commercially available components.
There are two ways here - install the AUX connector in the radio yourself, or go the more complicated way and set up a wireless circuit that works, like factory counterparts, using the Bluetooth wireless data transfer protocol. The last option only seems complicated, but in fact it turns out to be even simpler than the first option. So, let's see how this can be organized.
The first option would be to purchase and install a factory hands-free kit. Such a set consists of a wireless module, a microphone and a speaker, or outputs for integration with the speakers of an audio system. The connection diagram of the device depends on its technical features and is carried out in accordance with the instructions and diagram attached to the product. The price of such a module is about one, two or three thousand rubles.
There is another option that is suitable for electronics lovers. You can make a wireless speakerphone in a car with your own hands, taking as a basis ... a regular wireless Bluetooth headset. This will require, in fact, the headset itself (an old workable product is quite suitable), as well as an old non-working radio receiver, which can become a “donor” for spare parts, including, for example, a TDA7385 ULF chip or similar.
Conventionally, the scheme can be divided into four main blocks:
- Directly the headset, which displays contacts from the speaker, microphone and power. In the case of the output of contacts from the power supply, the built-in battery is dismantled.
- ULF scheme. It is better to use a chip that has standby and mute outputs, which will make it possible to control the current consumed by the device.
- The power supply, the manufacture of which should be approached very responsibly. It should be remembered that standard telephone headsets are very sensitive to power, and an increase in voltage can easily disable the device, and you will not be able to restore it.
- An automatic control unit, whose task is to monitor the signal at the output of the former headset and close the low power relay, which will supply voltage to the input that muffles the sound of the radio, as well as to the “standby” and “mute” ULF connectors in order to turn on the speakers.
The constructed device allows you to use all the functions of a wireless headset with a "binding" to the car radio. That is, the phone is synchronized with the headset according to the standard scheme, but the voice is transmitted not to the headset, but to the speakers of the radio.

In addition, the headset microphone can be extended and placed in any convenient location as close to the driver as possible. Accordingly, the voice quality will be at a high level.
Of course, many readers will ask whether it makes sense to go to such difficulties. Perhaps the answer to this question is yes only if you have the necessary components and an old, unused, wireless headset. Otherwise, buying a ready-made speakerphone module will cost even less, not to mention a much simpler installation scheme.
Results
As we can see, it is quite possible to make a speakerphone through the radio in a car with your own hands. In some cases, such design changes are justified. However, do not forget that these tips are suitable, first of all, for owners of used cars.
In the case of a new car, we would like to warn owners against this kind of “improvements”. This is due not only and not so much to technical difficulties, but to the issue of a guarantee for a car.
Classification of HandsFree Devices
You can use your phone hands-free in a car in a variety of ways: by purchasing a headset, by installing a portable or full hands-free kit. Each of the types of devices differs in the installation method, the principle of operation, the set of useful functions and, of course, the cost.
Headset- the simplest type of HandsFree device, as a result of which the speakerphone is installed in the car. Cable, microphone and headphones - the whole set of this type of device. For it to work, you only need to connect the headset to the phone using a cable. The head part of the headset can be different: either a combined earpiece-microphone in one block, or each device separately.
Portable kit is a speaker with an external microphone (in some models, however, only the standard phone microphone is used), which can be mounted in the cigarette lighter or other convenient place in the cabin. The headset communicates with the phone via wire or bluetooth. Devices of this type can be both universal, i.e. suitable for most phone models (for example, mr. HandsFree), and model.
Full set, for example, the Parrot brand, requires integration into the car's electronic system and installation in a car service. Thanks to this device, a wireless speakerphone is provided. For this, either the speakers of the stereo system or the standard speakers of the kit are used. In addition to the fact that the complete set provides excellent communication quality, it allows you to use the voice interface, automatic volume control of the audio system and other useful functions.

That is why the speakerphone in the car or "Hand free" was developed.
This system provides hands-free communication in the car, which allows you to talk on the phone and drive at the same time. In addition, the speakerphone was invented a long time ago, but only relatively recently began to gain popularity.
Device Varieties
All speakerphone is divided into:
- Built-in external speaker.
- State acoustics.
When installing standard acoustics in a car, you have to turn to specialists for help, but it has excellent sound quality. When there is an incoming call, the system automatically adjusts the volume. Some models are equipped with the A2DP function, which plays music from the phone.
Devices in the car differ from each other in the method of reflecting information, that is, some are equipped with a display (monochrome or color), while other models do not have it. Display systems are convenient in that the phone number of the caller is displayed on the screen.
Speakerphone for car
Let's analyze the means of communication that are allowed to be used in the car:
- Hands Free System.
- Headset.
- Speakerphone Parrot Minikit Neo 2 HD.
One of the first invented devices in the car is the Hands-Free system. This compact device attaches to your ear and allows you to talk on the phone without hands. It consists of a microphone, an earpiece, a battery and a Bluetooth module. The system has numerous advantages:
- Confidentiality of conversations because they are transmitted through headphones.

Headsets are designed specifically for use in the car. The principle of their operation is also based on the Bluetooth module, but the system is made a little differently. Instead of an earpiece, a speaker is used here, and the headset itself is attached to the front panel of the car. Thus, managing the system is much easier.
Devices are removable and pluggable. Removable are considered completely autonomous, they can be used in any convenient place. 
The accumulator is charged from the socket or an onboard network of a car. Removable systems have the following advantages:
- Universal.
- Simple and comfortable to operate.
- Able to work for a long time.
The plug-in ones are installed in the standard audio system, while the microphone is output separately and attached anywhere in the cabin. The conversation is played through the speakers of the audio system. Its quality is improved, but such devices are quite difficult to connect.
Parrot devices are the most affordable and inexpensive option. The system is easily mounted in the car, and phones are fixed thanks to reliable clothespins and holders.
