Old car music promotion report of Ruimi car Bluetooth player trial

[Write before probation]

Where there is oppression, there is resistance. Similarly, where there is complaint, there is a need to be solved. At Laoluo's year-end closed box crosstalk performance years ago, Zhu Xiaomu, the product director, introduced an external application - hammer driving. This software came into being against the background of poor experience of traditional vehicle navigation. It reduced the common main interface of vehicle operation to only three functions: navigation, music and telephone. This allows us to clearly see the pain points and needs of users in the driving scene, and also reflects that music is really a strong demand when driving.

Of course, what hammer driving solves is only the problem of navigation, and the need to listen to music also needs to be solved urgently. At present, most of the original automobile machines can support external storage such as CD, U disk, SD card, etc. The song update stored in such external storage is a big problem: CD disk is not an update, only more CDs can be purchased; USB flash drive and SD card usually need to be taken out and connected to the computer for song update. The operation is not difficult but the steps are quite tedious; AUX input can solve all the above problems, but when you plug in the cable and unplug the cable, you are drunk. In contrast, it is much more convenient to support Bluetooth connection to listen to music on the mobile phone. The music in the mobile phone is updated in the wifi environment, and it is automatically connected after getting on the car. It is completely foolproof.

So when we saw that Youruimi, a device that can enable old cars to support Bluetooth, applied decisively and won the lottery in JD Smart crowd test. After winning the bid and before receiving the product, I did some homework first, that is, the working principle of the Ruimi car borne Bluetooth player. It is connected to the mobile phone through Bluetooth, and at the same time it transmits FM signals. The car radio can tune to the corresponding FM frequency to enjoy the music being played in the mobile phone.

While focusing on Ruimi, I also learned about similar products, such as Che Tingbao. It also transmits FM, but the difference is that the songs stored in the mobile phone are synchronized to Che Ting Bao via wifi connection, which means Che Ting Bao is a storage device itself. In order to facilitate comparison, I have made a small picture as above. Which product is better to use? At the end of this paper, a simple analysis is also made.

[Unpacking and appearance]

The simple paper packaging is only half the size of a palm, which conforms to Xiaomi's consistent style and temperament. There is only the ROIDMI brand logo on the front and some product information on the back. Having seen the tall transparent packaging box of similar products, it is quite luxurious, so I didn't comment.

The inner cup is also paper-based, and the product is light, so the pressure should be low. The player has finally made its debut. The highlight surface of the body is injected once, and the top surface is frosted, which is simple and exquisite overall.

There is a QR code sticker on the plastic end of the player, and Android phones can scan the QR code and download it to the corresponding control APP - on-board Bluetooth FM. The iOS version is not open yet.

After the sticker is removed, the two USB sockets immediately appear, 5V 2.1A, which should be the voltage and maximum current output by a single port. According to official data, the total output current of two ports can reach 3.1A.

Look at one end of the metal electrode. It is also smooth and bright. Different from the common car charger plug, Ruimi player uses "360 degree full contact snap connection technology to make electrodes", which is also the reason why some models cannot be used. It is believed that this is also a rather puzzling decision to choose between safety and suitable models.

Episode: According to official tips, FAW Volkswagen's new Jetta is on the list of models that are not supported, but after actual observation, it is found that the cigarette lighter of the new Jetta (13 models) is indeed a cartridge type. Is it the official mark wrong?

[Actual measurement on iPhone]

After photographing the appearance, I can't wait to get on the car and test it. The equipment I brought is as follows: one iPhone/Android data cable, the player itself, the current and voltage tester, and of course, two iPhones/Android phones.

Before the official measurement, let's compare the power supply plug of Ruimi player with that of traditional cigarette lighter. The power supply plug of the DASH CAM is shown, which is quite different.

Insert the player and it will light up perfectly. The player will emit a blue green light in the USB port.

I tested my iPhone first. At this time, I can find the option of "Ruimi Car borne Bluetooth Player" in the Bluetooth list of my phone. Click it to connect. Adjust the car radio to FM 96.4MHz, and the mobile phone plays music (such as turning on NetEase Music, QQ Music, etc.). When the music in the mobile phone is played through the car stereo, I can't help but say: Hmm, this is the function I want.

In the subsequent use process, it was found that if the mobile phone was used for navigation, the navigation voice could also be synchronously output to the car audio, so that there was no need to struggle with the small navigation voice of the mobile phone. Similarly, playing games and watching blockbuster audio on mobile phones can also be played through car stereos. Hmm, are you happy?

[Android phone measurement]

The iPhone connection operation is so simple, but what about Android phones? In fact, Android or other mobile phones that support Bluetooth can be so simple, so no demonstration will be made. However, this player's dedicated APP has other uses, so you might as well try it.

As explained above, you can download the special APP for this device by scanning the QR code on the sticker. Open the APP and follow the prompts step by step. If you don't have a Xiaomi account, you can apply for one. In the process, you will also be prompted to manually connect to Bluetooth.

Next, APP will recommend an FM frequency according to different regions (you can also modify the frequency in the settings later). After voice detection, you can select a default music player to enjoy music. In the future, when the mobile phone is connected to Ruimi, the set music player can be automatically started to play. The whole process is easy.

To sum up, the role of Android APP is actually to make personalized settings, including light settings, frequency modification, and default playback software settings.

[USB charging measurement]

Ruimi player has two USB charging ports, which is one of the reasons why I like this product. Listening to music, mobile phone charging, and driving recorder are conducted at the same time.

Insert the current and voltage tester into Ruimi's USB interface, and the voltage is stable at 5.2V under no-load condition. When charging the iPhone, the voltage is 5.1V, and the current is stable at 1.06A (at this time, the iPhone power is 33%).

When charging the iPad, the voltage is 5.1V, and the current is kept at about 1.66A (at this time, the iPad power is 59%). It can be seen that the USB output voltage is sufficient, and the current is automatically adjusted according to different devices.

How about charging two USB ports at the same time? Connect the current and voltage tester to the charging circuit of the iPhone, and then connect another USB to charge the iPad. At this time, the charging current of the iPhone is 1.04A, and the difference between the current when the iPhone is charged and the current when the iPhone is charged alone is almost negligible. The current between the two USB has almost no effect. (The sum of single charging current is not more than 3.1A)

Since Ruimi has been on duty, the power supply plug of the cigarette lighter matched with the DASH CAM will not work. So after all the tests have been completed, the system will decisively set the following parameters:? Subtract the power plug of the tachograph (rated input 5V/1A), find a USB plug of the old mouse (try to be thicker), and connect it together according to the principle of connecting the same color. In this way, the tachograph can get power from Ruimi. If you are in pursuit of perfection, you can directly purchase a sufficient length of USB cable for the DASH CAM on a treasure.

[Advantages, disadvantages and summary]

The advantages are obvious:

1. It is easy to play the music in the mobile phone;

2. Dual USB output, the dash cam and mobile phone can be charged correctly;

3. Support mobile navigation voice.

a fly in the ointment:

1. Although it is a combination of 360 degree full contact buckle and elastic cigarette lighter, there are two power interruptions in the use of several days, which still needs further improvement in industrial design;

2. The sound quality is average, and there is still a certain gap between the sound quality and that of AUX input.

Comparison with similar products:

1. Compared with Wifi connected players, Ruimi players do not contain storage media, so the cost and price are naturally lower;

2. Most similar products have a knob or button, while USB has only one. In fact, the songs saved in users' mobile phones are usually their favorite songs to listen to. Is the demand for cutting songs really high? Moreover, it is as safe as Zhu Xiaomu said: multiple buttons on the car will make the relatives cry. In contrast, it is better to make an extra USB for the space saved.

Summary:

Although there is no specific statistics, I believe that the car machine without Bluetooth function has a high market share, in other words, the market is very large. The appearance of Ruimi's on-board Bluetooth player not only makes up for the lack of Bluetooth functions in mid and low-end models, but also provides more power outlets for emerging smart cars, which can be said to be more at one stroke. In general, as a small toy on Xiaomi's ecological chain, Ruimi's mobile Bluetooth player is a product worth buying. What's a bicycle if you buy a Bluetooth player and high-quality two port car charger at the price of 69 yuan? (Do you dare to use the cheap car charger on a treasure?) In addition, according to the introduction on the official website of Ruimi, "Ruimi Smart Life" cannot only make this product. I believe that more intelligent cars from Ruimi will appear in the future.
