Embodiment 1

[0101] The electronic equipment is such as Figure 3A , Figure 3B and Figure 3C As shown in the notebook, the main body where the keyboard of the notebook is located is the second main body 202 . The notebook may include a double hinge 301 , through which the first main body 201 can be rotated 370° relative to the second main body 202 .

[0102] In the embodiment of the present invention, the electronic device includes at least two speaker units. Preferably, the electronic device may include four speaker units to achieve a better effect. Of course, it is also possible to include more speaker units. Yes, but it is necessary to consider the volume and weight of the electronic device, so it is better to include four speaker units in the electronic device. In this embodiment, it is better to include four speaker units in the electronic device. For example, they are respectively the first speaker unit, the second speaker unit, the third speaker unit and the fourth speaker unit...

Embodiment 2

[0109] The electronic equipment is such as Figure 4A , 4B For the PAD shown in 4C, the first main body 201 is the main body where the display screen of the PAD is located, and the second main body 202 may be the base of the PAD, and the base may include components such as a keyboard. The electronic device may further include a connecting piece 401 for connecting the first body 201 and the second body 202 .

[0110] In this embodiment, the electronic device includes four speaker units as an example for illustration, which are respectively the first speaker unit, the second speaker unit, the third speaker unit and the fourth speaker unit, wherein the The first speaker unit and the third speaker unit are high-frequency speaker units, and the second speaker unit and the fourth speaker unit are low-frequency speaker units. And in this embodiment, the first speaker unit and the second speaker unit are arranged on the first main body 201, and the third speaker unit and the fourth ...

Embodiment 3

[0116] The electronic equipment is such as Figure 5A and 5B For the notebook shown, the main body where the display screen of the notebook is located is the first main body 201 , and the main body where the keyboard of the notebook is located is the second main body 202 .

[0117] In this embodiment, the electronic device includes four speaker units as an example for illustration, which are respectively the first speaker unit, the second speaker unit, the third speaker unit and the fourth speaker unit, wherein the The first speaker unit and the third speaker unit are high-frequency speaker units, and the second speaker unit and the fourth speaker unit are low-frequency speaker units. And in this embodiment, the first speaker unit, the second speaker unit, the third speaker unit and the fourth speaker unit are all arranged on the second main body 202, wherein the first The speaker unit and the third speaker unit are arranged on the first surface of the second body 202, that ...

Abstract

The invention discloses a method for controlling sound output. The method for controlling sound output is used for achieving output of surround sounds. The method for controlling sound output comprises the steps that the position of a first subject and the position of a second subject are obtained, the current usage mode of electronic equipment is determined according to the position of the first subject and the position of the second subject, the electronic equipment is controlled to output first sounds in a first sound output mode when the electronic equipment is in a first usage mode, and the electronic equipment is controlled to output second sounds in a second sound output mode when the electronic equipment is in a second usage mode. The invention further discloses the electronic equipment used for realizing the method.

Description

technical field [0001] The invention relates to the fields of electronics and computers, in particular to a method for controlling sound output and electronic equipment. Background technique [0002] The sound effect of common electronic products at present is difficult to achieve the effect of surround sound, and all have the defect that the loudness and the bandwidth cannot be balanced. [0003] Existing solution 1: Use a filter to forcibly divide the sound signal into high and low frequencies, and then use the difference in the time between the high and low frequencies to reach the human ear to achieve a stereo effect. [0004] Disadvantages of this solution: filter devices are used, which increases the cost, and may cause problems such as electromagnetic interference and poor heat dissipation. [0005] Existing solution 2: simply use a speaker unit with high power. [0006] The disadvantages of this solution are: the product size needs to be increased, and the sound wo...
