An air-pressure soundbox is provided. The air-pressure soundbox includes a cabinet, a sound generation unit and a first ventilation panel. The cabinet has a first side surface and a second side surface opposite to each other, and includes an opening on the first side surface. The sound generation unit is disposed in the opening to seal the cabinet for forming an enclosed space. A horn of the sound generation unit faces an external space outside the cabinet. The first ventilation panel is disposed in the enclosed space to divide the enclosed space into a first subspace and a second subspace.

Air-pressure soundbox

A sound emitting device includes a speaker box, a loudspeaker, a temperature sensor, a central processing unit and a signal amplifier. The speaker box includes a sound hole. The temperature sensor detects a temperature of the sound emitting device and generates a detection signal. The central processing unit pre-stores a default audio signal. When the central processing unit determines that the loudspeaker is in a standby state and the temperature of the sound emitting device exceeds a threshold value, the central processing unit issues the default audio signal. The signal amplifier is connected to and disposed between the central processing unit and the loudspeaker for amplifying the default audio signal and transmitting the amplified default audio signal to the loudspeaker. A vibration diaphragm of the loudspeaker undergoes a vibration action according to the amplified default audio signal.

Sound emitting device using loudspeaker to dissipate heat and control method thereof

A detachable smart speaker system and a control method thereof are disclosed. The detachable smart speaker system includes a core device and a pairing device. The core device includes a microphone array, a CPU, a wireless communication module, a core bridge element and a database. The microphone array, the core bridge element and the database are connected to the CPU. The database includes plural audio parameter sets. The pairing device includes a speaker, a microcontroller unit, a pairing bridge element, and an identification code. The speaker and the pairing bridge element are connected to the microcontroller unit, respectively. The pairing device is detachably connected to the core device through the pairing bridge element, and a corresponding audio parameter set is to be selected from the audio parameter sets of the database according to the identification code. The core device controls the pairing device according to the corresponding audio parameter set.
