"No 7.1 surround sound" means that the audio system does not support the 7.1 surround sound format. Surround sound systems with 7.1 channels provide a more immersive audio experience by using seven speakers and one subwoofer to create a more realistic and enveloping sound environment. Without 7.1 surround sound, the audio system may only support a different format, such as stereo or 5.1 surround sound, which may not provide the same level of immersion and spatial audio effects. **

If the Bluetooth speaker is connected to the smartphone but there is no sound, there are a few potential reasons for this issue. First, check the volume settings on both the smartphone and the Bluetooth speaker to ensure they are not muted or set too low. Additionally, make sure the Bluetooth speaker is selected as the audio output device on the smartphone. If these steps do not resolve the issue, try disconnecting and reconnecting the Bluetooth connection, or restarting both the smartphone and the Bluetooth speaker. If the problem persists, there may be an issue with the Bluetooth connection or the speaker itself, and further troubleshooting or technical support may be necessary. **

It ultimately depends on your specific needs and preferences. A soundbar with surround sound typically offers a more immersive audio experience, with separate speakers to create a more realistic surround sound effect. On the other hand, an adaptive soundbar is designed to analyze the acoustics of your room and adjust the sound output accordingly, providing a more customized listening experience. If you prioritize a more immersive surround sound experience, a soundbar with surround sound may be better for you. However, if you value a more personalized and adaptable audio experience, an adaptive soundbar may be the better choice. **

Bluetooth technology allows for wireless communication between devices within a short range. When a mobile phone is connected to a Bluetooth speaker, the phone sends audio data to the speaker using radio waves. The speaker then receives the data and converts it into sound waves that can be heard. On the other hand, the regular mobile phone speaker works by converting electrical signals from the phone into sound waves using a diaphragm and a magnet to produce sound. Both Bluetooth and regular mobile phone speakers rely on the conversion of electrical signals into sound waves, but Bluetooth technology allows for wireless transmission of audio data. **
