Sound output systems in a terminal device

A terminal device, comprising:

• a middle frame with a first through hole and a second through hole;
• a display module mounted on the middle frame;
• a sound output device located on a side of the middle frame away from the display module;
• a first sound output hole set;
• and
• a second sound output hole set;
• wherein
• the first sound output hole set and the second sound output hole set are provided between a top of the terminal device and the sound output device;
• wherein the sound output device and the first sound output hole set are located on a first side of a center of the top of the terminal device, and the sound output device is opposite to the first sound output hole set;
• wherein the second sound output hole set is located on a second side of the center of the top of the terminal device;
• wherein the sound output device is fixed to the middle frame by a bracket;
• wherein the bracket is provided with a first groove close to the middle frame, and wherein the first groove comprises a first groove section, a second groove section, and a third groove section located between the first groove section and the second groove section;
• wherein the first groove section and the first through hole are opposite to the first sound output hole set, and the second groove section and the second through hole are opposite to the second sound output hole set;
• wherein the sound output device is in communication with the first sound output hole set through the first groove section and the first through hole, and the sound output device is in communication with the second sound output hole set through the first groove section, the second groove section, the third groove section, and the second through hole;
• and
• wherein a channel is formed in the third groove section or in the bracket and the channel is configured to allow sound transmission to bypass a bottleneck caused by a camera module and to improve a screen-to-body ratio of the terminal device.
