Description

Content connection method and device Technical Field The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for content connection. Background With the development of terminal technology, content connection between multiple electronic devices can be realized, that is, seamless access and continuous processing of the same content and/or task between multiple electronic devices can be realized. At present, the functions of multi-screen collaboration, file mutual transmission, application circulation and the like of electronic equipment can enable content connection among different electronic equipment. In some scenarios, multi-screen collaboration, file interaction, and application streaming of the electronic device may all be implemented through a "one touch" feature. For example, a near field communication (NEAR FIELD communication) chip is deployed on a mobile phone, an electronic tag is deployed on a notebook computer, and when the NFC chip of the mobile phone is close to the electronic tag of the notebook computer, data can be transmitted between the mobile phone and the notebook computer, so that multi-screen collaboration, file mutual transmission and application circulation are realized. However, this approach may additionally increase the cost of the electronic device. Disclosure of Invention The application provides a content connection method and a device, which are beneficial to completing the content connection between electronic devices without increasing the cost of the electronic devices additionally. In a first aspect, an embodiment of the present application provides a content connection method, where the method includes establishing a wireless communication connection between a first device and a second device, performing ultrasonic ranging based on a speaker and/or a microphone of the first device and the second device, where the first device calculates a distance between the first device and the second device, and sending, by the first device, content displayed by the first device to the second device through the wireless communication connection when the distance between the first device and the second device is less than or equal to a distance threshold. The ultrasonic ranging may be one-way ultrasonic ranging or two-way ultrasonic ranging, which is not limited by the embodiment of the present application. For one-way ultrasonic ranging, the specific ranging method may refer to fig. 9, and for two-way ultrasonic ranging, the specific ranging method may refer to fig. 5 or fig. 7, which are not described herein. The distance threshold may be used to indicate that the first device is in proximity to the second device. If the ultrasonic ranging is two-way ultrasonic ranging, the determination of the distance threshold may refer to fig. 6, and will not be described in detail herein. Under the condition that wireless communication connection is established, the distance between the first equipment and the second equipment is smaller than or equal to a distance threshold value, the condition of content connection is met, and content connection can be performed, namely, the first equipment sends content displayed by the first equipment to the second equipment through the wireless communication connection, so that under the condition that NFC chips and electronic tags are not deployed by the first equipment and the second equipment respectively, content connection can be realized by using speakers and/or microphones which are included by most of equipment, and the cost of the electronic equipment is not increased additionally while content connection between the electronic equipment is facilitated. In one possible implementation, the distance between the first device and the second device is calculated based on ultrasonic ranging of the speaker and/or microphone of the first device and the second device, if one or more of the following conditions are met, the first device is in a motion state, or the gesture of the first device meets a preset gesture, the preset gesture comprises that the top position of the front surface of the first device points to the second device, or the intensity of the wireless signal received by the first device is greater than a first intensity threshold. In one example, the first device calculates a distance between the first device and the second device based on ultrasonic ranging of a speaker and/or microphone of the first device and the second device with the first device in motion. In this way, the first device is in a motion state, which indicates that the user is using the first device, and can perform ranging to determine whether the user wants to continue the content, so that the probability of false triggering of the content is reduced. In another example, in a case where the pose of the first device satisfies the preset pose, the first device performs ultrasonic ranging based on the speake
