Abstract: Provided is a loudspeaker applied to an electronic device, including: a speaker body configured for vibrating and producing sound; a first acoustic channel having a first end communicated with the speaker body and a second end forming a first sound output port on a case of the electronic device; and a second acoustic channel having a first end communicated with the speaker body and a second end forming a second sound output port on the case of the electronic device. The first and second sound output ports are located on adjacent wall surfaces of the case of the electronic device. Compared with the related art, larger port area can be achieved by separately forming sound output ports on adjacent walls of the housing, resulting in high frequency response and higher gain. The horn-shaped sound output port facilitates design and reduces flow-related distortion and noise at low frequencies.

Abstract: An electronic device includes an enclosure defining a chamber and a first output port communicating the chamber with outside of the enclosure; a loudspeaker module disposed within the chamber. The loudspeaker module includes a first front cavity in communication with the first output port, a second front cavity acoustically connected with an inside space of the enclosure, a rear cavity, a transducer disposed between the first front cavity and the rear cavity, and a first passive radiator disposed between the second front cavity and the rear cavity. The passive radiator is capable of radiating low-frequency sound to the inside space of the enclosure via the second front cavity and an inside port or a second passive radiator. Then, the low-frequency sound re-radiates through surfaces of the enclosure and possible leaks in the enclosure to the outside environment. The low-frequency output is boosted.

Abstract: A method for testing user experience, comprising steps of: acquiring test indicating information; releasing a main task and an auxiliary task according to the test indicating information, each auxiliary task includes the main task and a corresponding physical signal providing prompting effect or inhibiting effect to the main task; acquiring feedback response information of a subject corresponding to the main task and the auxiliary task. In the technical solution of the present disclosure, through comparison of feedback response information of the subject between the auxiliary task and the main task, the perception situation of the subject on physical signals can be determined, and through comparison of feedback response information of the subject between the auxiliary tasks, the perception situation of the subject on different physical signals can be determined, thereby improving the effectiveness of the test result on perception attributes of physical signals.
