Students from time to time in the class reflected from time to time that their voices were small, and it was a bit difficult for them to scream loudly, especially if classes were not well scheduled. There were four classes in the morning and they did not want to say anything. Some colleagues around us bought such a small loudspeaker. I heard that the effect was good. Then I also bought a try to see if I could use a device to relieve the burden of a bit of dice.
ShotThe colleague used a bee, so he searched and found it:
Orders on the 23rd, today's harvest, not fast. Shangjing East House looked for it, there are 69, but the color is not the same.
Is this also going to be out of the box? Some of the deformation of the express box pressure is not on the map.
It's strange why the charging head is outside the box? Is the default is without a charger?
Open the box, the intention is to remove the amplifier, the result of accidentally fell out of all accessories: headset, charging cable, lanyard, see below:
The specific configuration is as follows (web page screenshot):
It's about the same size as a cell phone and weighs a bit more than a cell phone. It's a bit longer than a cell phone. The thickness of a cell phone is so thick. It's difficult to put it in your pocket (Huawei P8 on the left):
1, loud speaker
This is its main function. There are two knobs on the top of the loudspeaker, one for switching and adjusting the volume, and the other for adjusting the reverberation size. Turn on the power, plug the mic jack into the headset, the default into the amplified mode, after reading the box did not read the instructions, plug in the headset directly boot, is a scream, the sound is too loud, quickly shut down to see instructions. To avoid echo and howling during use, the distance between the microphone and the host must be kept at a distance of 50cm or more so as not to affect normal use. The amplifier has a so-called intelligent voice function. When it is turned on, it will first voice remind the current working mode, and the switch will remind the current operation.
When I started the audition, the echo was obvious, and my heart was a little buzzing. The effect of this sound effect was definitely discounted. Try to adjust the reverberation knob (ECHO) according to the instruction manual. The echo disappears. The results of other loudspeakers reflecting loud sounds are good. Well, wait for the class to see what the classroom effect looks like.
2, other
This multi-functional device has a number of other features in addition to the main loudspeaker. The other functions can be switched by the M key on the front of the host.
FM radio pulls out the antenna, presses “M†key, adjusts to FM mode, presses “start pause†button again, automatically searches for stations. In the city, 7 or 8 channels of broadcasting can be found. The effect is the same as that of the car radio. Do not support receiving the search station, so if you want to listen to the enemy's station, forget it.
The TF card/U disk player has a TF card socket at the top of the host and a USB standard Type-A socket and a Mini-USB interface at the right side. Can play TF card or U disk store MP3, WMA format audio. U disk audio can play this feature is still very good, to the students to play an English listening, telling a story to the children it ... ... convenient, practical, but if you want to use TF card is not so convenient, or to own a read The card reader is either copied to the TF card via a mobile phone and played in the loudspeaker. Because the machine's own Mini-USB port can only be used for charging, the TF card cannot be operated by connecting the computer.
After the audio input is connected to the host via the AUX audio cable, the host can be used as an active speaker for computers, mobile phones, MP3s, and other devices. Special note: This feature is not tested, mainly because it is not equipped with an AUX audio cable and it cannot connect peripherals.
Charging When the battery icon flashes on the screen, the main unit needs to be charged. Use the supplied power adapter (output 5V/500mA) and charging cable to charge from the Mini-USB connector on the right side. In fact, on the prevailing interface, if you configure the Micro-USB interface, you can use the extra mobile phone charger at home to charge the machine. The machine also saves the cost of the charger. The mainframe is equipped with a 1500mA lithium battery. It takes about 3-5 hours to fully charge the charger and 12-18 hours for charging. One charge can be used once a week, but there is still no measurement.
One-key recording In the case of accessing a U disk or TF card, insert a microphone, press the "Stop" button to start recording, and there will be a voice prompt before starting recording. After the recording is completed, press the "Stop" button again to play the previous one. Recording, but how to switch the function still have to fumble for a few more times, and, after starting the recording, it is necessary to wait a minute or two to record the sound and lose some sound in front of it. Feel this feature is not useful.
summaryThe sound amplification function of this bee microphone is enough, the sound quality is clear, and the sound amplification effect is good. However, the extension function is open to question, a tens of yuan worth of products, should focus on the main features to do better and stronger, in the current everyone with a powerful smart phone, affiliated FM radio, audio playback, AUX The use of recording, recording, etc. is not very useful. Increasing them will increase costs and reduce competitiveness. It is better to reduce the function, improve the quality, and improve the competitiveness.
